Stiffness and Torsional Vibration of Spline-Couplings

In this paper, we describe some basic characteristics of spline-coupling and examine its torsional vibration behavior. We also explore the effect of spline misalignment on rotor-spline coupling. These results will assist in the design of improved spline-coupling systems for various applications. The results are presented in Table 1.
splineshaft

Stiffness of spline-coupling

The stiffness of a spline-coupling is a function of the meshing force between the splines in a rotor-spline coupling system and the static vibration displacement. The meshing force depends on the coupling parameters such as the transmitting torque and the spline thickness. It increases nonlinearly with the spline thickness.
A simplified spline-coupling model can be used to evaluate the load distribution of splines under vibration and transient loads. The axle spline sleeve is displaced a z-direction and a resistance moment T is applied to the outer face of the sleeve. This simple model can satisfy a wide range of engineering requirements but may suffer from complex loading conditions. Its asymmetric clearance may affect its engagement behavior and stress distribution patterns.
The results of the simulations show that the maximum vibration acceleration in both Figures 10 and 22 was 3.03 g/s. This results indicate that a misalignment in the circumferential direction increases the instantaneous impact. Asymmetry in the coupling geometry is also found in the meshing. The right-side spline’s teeth mesh tightly while those on the left side are misaligned.
Considering the spline-coupling geometry, a semi-analytical model is used to compute stiffness. This model is a simplified form of a classical spline-coupling model, with submatrices defining the shape and stiffness of the joint. As the design clearance is a known value, the stiffness of a spline-coupling system can be analyzed using the same formula.
The results of the simulations also show that the spline-coupling system can be modeled using MASTA, a high-level commercial CAE tool for transmission analysis. In this case, the spline segments were modeled as a series of spline segments with variable stiffness, which was calculated based on the initial gap between spline teeth. Then, the spline segments were modelled as a series of splines of increasing stiffness, accounting for different manufacturing variations. The resulting analysis of the spline-coupling geometry is compared to those of the finite-element approach.
Despite the high stiffness of a spline-coupling system, the contact status of the contact surfaces often changes. In addition, spline coupling affects the lateral vibration and deformation of the rotor. However, stiffness nonlinearity is not well studied in splined rotors because of the lack of a fully analytical model.

Characteristics of spline-coupling

The study of spline-coupling involves a number of design factors. These include weight, materials, and performance requirements. Weight is particularly important in the aeronautics field. Weight is often an issue for design engineers because materials have varying dimensional stability, weight, and durability. Additionally, space constraints and other configuration restrictions may require the use of spline-couplings in certain applications.
The main parameters to consider for any spline-coupling design are the maximum principal stress, the maldistribution factor, and the maximum tooth-bearing stress. The magnitude of each of these parameters must be smaller than or equal to the external spline diameter, in order to provide stability. The outer diameter of the spline must be at least 4 inches larger than the inner diameter of the spline.
Once the physical design is validated, the spline coupling knowledge base is created. This model is pre-programmed and stores the design parameter signals, including performance and manufacturing constraints. It then compares the parameter values to the design rule signals, and constructs a geometric representation of the spline coupling. A visual model is created from the input signals, and can be manipulated by changing different parameters and specifications.
The stiffness of a spline joint is another important parameter for determining the spline-coupling stiffness. The stiffness distribution of the spline joint affects the rotor’s lateral vibration and deformation. A finite element method is a useful technique for obtaining lateral stiffness of spline joints. This method involves many mesh refinements and requires a high computational cost.
The diameter of the spline-coupling must be large enough to transmit the torque. A spline with a larger diameter may have greater torque-transmitting capacity because it has a smaller circumference. However, the larger diameter of a spline is thinner than the shaft, and the latter may be more suitable if the torque is spread over a greater number of teeth.
Spline-couplings are classified according to their tooth profile along the axial and radial directions. The radial and axial tooth profiles affect the component’s behavior and wear damage. Splines with a crowned tooth profile are prone to angular misalignment. Typically, these spline-couplings are oversized to ensure durability and safety.

Stiffness of spline-coupling in torsional vibration analysis

This article presents a general framework for the study of torsional vibration caused by the stiffness of spline-couplings in aero-engines. It is based on a previous study on spline-couplings. It is characterized by the following 3 factors: bending stiffness, total flexibility, and tangential stiffness. The first criterion is the equivalent diameter of external and internal splines. Both the spline-coupling stiffness and the displacement of splines are evaluated by using the derivative of the total flexibility.
The stiffness of a spline joint can vary based on the distribution of load along the spline. Variables affecting the stiffness of spline joints include the torque level, tooth indexing errors, and misalignment. To explore the effects of these variables, an analytical formula is developed. The method is applicable for various kinds of spline joints, such as splines with multiple components.
Despite the difficulty of calculating spline-coupling stiffness, it is possible to model the contact between the teeth of the shaft and the hub using an analytical approach. This approach helps in determining key magnitudes of coupling operation such as contact peak pressures, reaction moments, and angular momentum. This approach allows for accurate results for spline-couplings and is suitable for both torsional vibration and structural vibration analysis.
The stiffness of spline-coupling is commonly assumed to be rigid in dynamic models. However, various dynamic phenomena associated with spline joints must be captured in high-fidelity drivetrain models. To accomplish this, a general analytical stiffness formulation is proposed based on a semi-analytical spline load distribution model. The resulting stiffness matrix contains radial and tilting stiffness values as well as torsional stiffness. The analysis is further simplified with the blockwise inversion method.
It is essential to consider the torsional vibration of a power transmission system before selecting the coupling. An accurate analysis of torsional vibration is crucial for coupling safety. This article also discusses case studies of spline shaft wear and torsionally-induced failures. The discussion will conclude with the development of a robust and efficient method to simulate these problems in real-life scenarios.

Effect of spline misalignment on rotor-spline coupling

In this study, the effect of spline misalignment in rotor-spline coupling is investigated. The stability boundary and mechanism of rotor instability are analyzed. We find that the meshing force of a misaligned spline coupling increases nonlinearly with spline thickness. The results demonstrate that the misalignment is responsible for the instability of the rotor-spline coupling system.
An intentional spline misalignment is introduced to achieve an interference fit and zero backlash condition. This leads to uneven load distribution among the spline teeth. A further spline misalignment of 50um can result in rotor-spline coupling failure. The maximum tensile root stress shifted to the left under this condition.
Positive spline misalignment increases the gear mesh misalignment. Conversely, negative spline misalignment has no effect. The right-handed spline misalignment is opposite to the helix hand. The high contact area is moved from the center to the left side. In both cases, gear mesh is misaligned due to deflection and tilting of the gear under load.
This variation of the tooth surface is measured as the change in clearance in the transverse plain. The radial and axial clearance values are the same, while the difference between the 2 is less. In addition to the frictional force, the axial clearance of the splines is the same, which increases the gear mesh misalignment. Hence, the same procedure can be used to determine the frictional force of a rotor-spline coupling.
Gear mesh misalignment influences spline-rotor coupling performance. This misalignment changes the distribution of the gear mesh and alters contact and bending stresses. Therefore, it is essential to understand the effects of misalignment in spline couplings. Using a simplified system of helical gear pair, Hong et al. examined the load distribution along the tooth interface of the spline. This misalignment caused the flank contact pattern to change. The misaligned teeth exhibited deflection under load and developed a tilting moment on the gear.
The effect of spline misalignment in rotor-spline couplings is minimized by using a mechanism that reduces backlash. The mechanism comprises cooperably splined male and female members. One member is formed by 2 coaxially aligned splined segments with end surfaces shaped to engage in sliding relationship. The connecting device applies axial loads to these segments, causing them to rotate relative to 1 another.

What Are Screw Shaft Threads?

A screw shaft is a threaded part used to fasten other components. The threads on a screw shaft are often described by their Coefficient of Friction, which describes how much friction is present between the mating surfaces. This article discusses these characteristics as well as the Material and Helix angle. You’ll have a better understanding of your screw shaft’s threads after reading this article. Here are some examples. Once you understand these details, you’ll be able to select the best screw nut for your needs.

Coefficient of friction between the mating surfaces of a nut and a screw shaft

There are 2 types of friction coefficients. Dynamic friction and static friction. The latter refers to the amount of friction a nut has to resist an opposing motion. In addition to the material strength, a higher coefficient of friction can cause stick-slip. This can lead to intermittent running behavior and loud squeaking. Stick-slip may lead to a malfunctioning plain bearing. Rough shafts can be used to improve this condition.
The 2 types of friction coefficients are related to the applied force. When applying force, the applied force must equal the nut’s pitch diameter. When the screw shaft is tightened, the force may be removed. In the case of a loosening clamp, the applied force is smaller than the bolt’s pitch diameter. Therefore, the higher the property class of the bolt, the lower the coefficient of friction.
In most cases, the screwface coefficient of friction is lower than the nut face. This is because of zinc plating on the joint surface. Moreover, power screws are commonly used in the aerospace industry. Whether or not they are power screws, they are typically made of carbon steel, alloy steel, or stainless steel. They are often used in conjunction with bronze or plastic nuts, which are preferred in higher-duty applications. These screws often require no holding brakes and are extremely easy to use in many applications.
The coefficient of friction between the mating surfaces of t-screws is highly dependent on the material of the screw and the nut. For example, screws with internal lubricated plastic nuts use bearing-grade bronze nuts. These nuts are usually used on carbon steel screws, but can be used with stainless steel screws. In addition to this, they are easy to clean.

Helix angle

In most applications, the helix angle of a screw shaft is an important factor for torque calculation. There are 2 types of helix angle: right and left hand. The right hand screw is usually smaller than the left hand one. The left hand screw is larger than the right hand screw. However, there are some exceptions to the rule. A left hand screw may have a greater helix angle than a right hand screw.
A screw’s helix angle is the angle formed by the helix and the axial line. Although the helix angle is not usually changed, it can have a significant effect on the processing of the screw and the amount of material conveyed. These changes are more common in 2 stage and special mixing screws, and metering screws. These measurements are crucial for determining the helix angle. In most cases, the lead angle is the correct angle when the screw shaft has the right helix angle.
High helix screws have large leads, sometimes up to 6 times the screw diameter. These screws reduce the screw diameter, mass, and inertia, allowing for higher speed and precision. High helix screws are also low-rotation, so they minimize vibrations and audible noises. But the right helix angle is important in any application. You must carefully choose the right type of screw for the job at hand.
If you choose a screw gear that has a helix angle other than parallel, you should select a thrust bearing with a correspondingly large center distance. In the case of a screw gear, a 45-degree helix angle is most common. A helix angle greater than zero degrees is also acceptable. Mixing up helix angles is beneficial because it allows for a variety of center distances and unique applications.

Thread angle

The thread angle of a screw shaft is measured from the base of the head of the screw to the top of the screw’s thread. In America, the standard screw thread angle is 60 degrees. The standard thread angle was not widely adopted until the early twentieth century. A committee was established by the Franklin Institute in 1864 to study screw threads. The committee recommended the Sellers thread, which was modified into the United States Standard Thread. The standardized thread was adopted by the United States Navy in 1868 and was recommended for construction by the Master Car Builders’ Association in 1871.
Generally speaking, the major diameter of a screw’s threads is the outside diameter. The major diameter of a nut is not directly measured, but can be determined with go/no-go gauges. It is necessary to understand the major and minor diameters in relation to each other in order to determine a screw’s thread angle. Once this is known, the next step is to determine how much of a pitch is necessary to ensure a screw’s proper function.
Helix angle and thread angle are 2 different types of angles that affect screw efficiency. For a lead screw, the helix angle is the angle between the helix of the thread and the line perpendicular to the axis of rotation. A lead screw has a greater helix angle than a helical one, but has higher frictional losses. A high-quality lead screw requires a higher torque to rotate. Thread angle and lead angle are complementary angles, but each screw has its own specific advantages.
Screw pitch and TPI have little to do with tolerances, craftsmanship, quality, or cost, but rather the size of a screw’s thread relative to its diameter. Compared to a standard screw, the fine and coarse threads are easier to tighten. The coarser thread is deeper, which results in lower torques. If a screw fails because of torsional shear, it is likely to be a result of a small minor diameter.

Material

Screws have a variety of different sizes, shapes, and materials. They are typically machined on CNC machines and lathes. Each type is used for different purposes. The size and material of a screw shaft are influenced by how it will be used. The following sections give an overview of the main types of screw shafts. Each 1 is designed to perform a specific function. If you have questions about a specific type, contact your local machine shop.
Lead screws are cheaper than ball screws and are used in light-duty, intermittent applications. Lead screws, however, have poor efficiency and are not recommended for continuous power transmission. But, they are effective in vertical applications and are more compact. Lead screws are typically used as a kinematic pair with a ball screw. Some types of lead screws also have self-locking properties. Because they have a low coefficient of friction, they have a compact design and very few parts.
Screws are made of a variety of metals and alloys. Steel is an economical and durable material, but there are also alloy steel and stainless steel types. Bronze nuts are the most common and are often used in higher-duty applications. Plastic nuts provide low-friction, which helps reduce the drive torques. Stainless steel screws are also used in high-performance applications, and may be made of titanium. The materials used to create screw shafts vary, but they all have their specific functions.
Screws are used in a wide range of applications, from industrial and consumer products to transportation equipment. They are used in many different industries, and the materials they’re made of can determine their life. The life of a screw depends on the load that it bears, the design of its internal structure, lubrication, and machining processes. When choosing screw assemblies, look for a screw made from the highest quality steels possible. Usually, the materials are very clean, so they’re a great choice for a screw. However, the presence of imperfections may cause a normal fatigue failure.
screwshaft

Self-locking features

Screws are known to be self-locking by nature. The mechanism for this feature is based on several factors, such as the pitch angle of the threads, material pairing, lubrication, and heating. This feature is only possible if the shaft is subjected to conditions that are not likely to cause the threads to loosen on their own. The self-locking ability of a screw depends on several factors, including the pitch angle of the thread flank and the coefficient of sliding friction between the 2 materials.
One of the most common uses of screws is in a screw top container lid, corkscrew, threaded pipe joint, vise, C-clamp, and screw jack. Other applications of screw shafts include transferring power, but these are often intermittent and low-power operations. Screws are also used to move material in Archimedes’ screw, auger earth drill, screw conveyor, and micrometer.
A common self-locking feature for a screw is the presence of a lead screw. A screw with a low PV value is safe to operate, but a screw with high PV will need a lower rotation speed. Another example is a self-locking screw that does not require lubrication. The PV value is also dependent on the material of the screw’s construction, as well as its lubrication conditions. Finally, a screw’s end fixity – the way the screw is supported – affects the performance and efficiency of a screw.
Lead screws are less expensive and easier to manufacture. They are a good choice for light-weight and intermittent applications. These screws also have self-locking capabilities. They can be self-tightened and require less torque for driving than other types. The advantage of lead screws is their small size and minimal number of parts. They are highly efficient in vertical and intermittent applications. They are not as accurate as lead screws and often have backlash, which is caused by insufficient threads.

How to Choose the Right Worm Shaft

You might be curious to know how to choose the right Worm Shaft. In this article, you will learn about worm modules with the same pitch diameter, Double-thread worm gears, and Self-locking worm drive. Once you have chosen the proper Worm Shaft, you will find it easier to use the equipment in your home. There are many advantages to selecting the right Worm Shaft. Read on to learn more.
worm shaft

Concave shape

The concave shape of a worm’s shaft is an important characteristic for the design of a worm gearing. Worm gearings can be found in a wide range of shapes, and the basic profile parameters are available in professional and firm literature. These parameters are used in geometry calculations, and a selection of the right worm gearing for a particular application can be based on these requirements.
The thread profile of a worm is defined by the tangent to the axis of its main cylinder. The teeth are shaped in a straight line with a slightly concave shape along the sides. It resembles a helical gear, and the profile of the worm itself is straight. This type of gearing is often used when the number of teeth is greater than a certain limit.
The geometry of a worm gear depends on the type and manufacturer. In the earliest days, worms were made similar to simple screw threads, and could be chased on a lathe. During this time, the worm was often made with straight-sided tools to produce threads in the acme plane. Later, grinding techniques improved the thread finish and reduced distortions resulting from hardening.
When a worm gearing has multiple teeth, the pitch angle is a key parameter. A greater pitch angle increases efficiency. If you want to increase the pitch angle without increasing the number of teeth, you can replace a worm pair with a different number of thread starts. The helix angle must increase while the center distance remains constant. A higher pitch angle, however, is almost never used for power transmissions.
The minimum number of gear teeth depends on the angle of pressure at zero gearing correction. The diameter of the worm is d1, and is based on a known module value, mx or mn. Generally, larger values of m are assigned to larger modules. And a smaller number of teeth is called a low pitch angle. In case of a low pitch angle, spiral gearing is used. The pitch angle of the worm gear is smaller than 10 degrees.
worm shaft

Multiple-thread worms

Multi-thread worms can be divided into sets of one, two, or 4 threads. The ratio is determined by the number of threads on each set and the number of teeth on the apparatus. The most common worm thread counts are 1,2,4, and 6. To find out how many threads you have, count the start and end of each thread and divide by two. Using this method, you will get the correct thread count every time.
The tangent plane of a worm’s pitch profile changes as the worm moves lengthwise along the thread. The lead angle is greatest at the throat, and decreases on both sides. The curvature radius r” varies proportionally with the worm’s radius, or pitch angle at the considered point. Hence, the worm leads angle, r, is increased with decreased inclination and decreases with increasing inclination.
Multi-thread worms are characterized by a constant leverage between the gear surface and the worm threads. The ratio of worm-tooth surfaces to the worm’s length varies, which enables the wormgear to be adjusted in the same direction. To optimize the gear contact between the worm and gear, the tangent relationship between the 2 surfaces is optimal.
The efficiency of worm gear drives is largely dependent on the helix angle of the worm. Multiple thread worms can improve the efficiency of the worm gear drive by as much as 25 to 50% compared to single-thread worms. Worm gears are made of bronze, which reduces friction and heat on the worm’s teeth. A specialized machine can cut the worm gears for maximum efficiency.

Double-thread worm gears

In many different applications, worm gears are used to drive a worm wheel. These gears are unique in that the worm cannot be reversed by the power applied to the worm wheel. Because of their self-locking properties, they can be used to prevent reversing motion, although this is not a dependable function. Applications for worm gears include hoisting equipment, elevators, chain blocks, fishing reels, and automotive power steering. Because of their compact size, these gears are often used in applications with limited space.
Worm sets typically exhibit more wear than other types of gears, and this means that they require more limited contact patterns in new parts. Worm wheel teeth are concave, making it difficult to measure tooth thickness with pins, balls, and gear tooth calipers. To measure tooth thickness, however, you can measure backlash, a measurement of the spacing between teeth in a gear. Backlash can vary from 1 worm gear to another, so it is important to check the backlash at several points. If the backlash is different in 2 places, this indicates that the teeth may have different spacing.
Single-thread worm gears provide high speed reduction but lower efficiency. A multi-thread worm gear can provide high efficiency and high speed, but this comes with a trade-off in terms of horsepower. However, there are many other applications for worm gears. In addition to heavy-duty applications, they are often used in light-duty gearboxes for a variety of functions. When used in conjunction with double-thread worms, they allow for a substantial speed reduction in 1 step.
Stainless-steel worm gears can be used in damp environments. The worm gear is not susceptible to rust and is ideal for wet and damp environments. The worm wheel’s smooth surfaces make cleaning them easy. However, they do require lubricants. The most common lubricant for worm gears is mineral oil. This lubricant is designed to protect the worm drive.
worm shaft

Self-locking worm drive

A self-locking worm drive prevents the platform from moving backward when the motor stops. A dynamic self-locking worm drive is also possible but does not include a holding brake. This type of self-locking worm drive is not susceptible to vibrations, but may rattle if released. In addition, it may require an additional brake to keep the platform from moving. A positive brake may be necessary for safety.
A self-locking worm drive does not allow for the interchangeability of the driven and driving gears. This is unlike spur gear trains that allow both to interchange positions. In a self-locking worm drive, the driving gear is always engaged and the driven gear remains stationary. The drive mechanism locks automatically when the worm is operated in the wrong manner. Several sources of information on self-locking worm gears include the Machinery’s Handbook.
A self-locking worm drive is not difficult to build and has a great mechanical advantage. In fact, the output of a self-locking worm drive cannot be backdriven by the input shaft. DIYers can build a self-locking worm drive by modifying threaded rods and off-the-shelf gears. However, it is easier to make a ratchet and pawl mechanism, and is significantly less expensive. However, it is important to understand that you can only drive 1 worm at a time.
Another advantage of a self-locking worm drive is the fact that it is not possible to interchange the input and output shafts. This is a major benefit of using such a mechanism, as you can achieve high gear reduction without increasing the size of the gear box. If you’re thinking about buying a self-locking worm gear for a specific application, consider the following tips to make the right choice.
An enveloping worm gear set is best for applications requiring high accuracy and efficiency, and minimum backlash. Its teeth are shaped differently, and the worm’s threads are modified to increase surface contact. They are more expensive to manufacture than their single-start counterparts, but this type is best for applications where accuracy is crucial. The worm drive is also a great option for heavy trucks because of their large size and high-torque capacity.

Product Description

 HUB BEARINGS is the main role of load-bearing and provide accurate guidance for the rotation of the hub, it bears both axial load and radial load, is a very important component. The traditional automobile wheel bearing is composed of 2 sets of tapered roller bearing or ball bearing. The installation, oiling, sealing and clearance adjustment of the bearing are all carried out on the automobile production line. This structure makes it difficult to assemble in the automobile production plant, high cost, poor reliability, and the car in the maintenance point maintenance, but also need to clean, oiling and adjustment of bearings. Wheel hub bearing unit is in the standard angular contact ball bearings and tapered roller bearings, on the basis of it will be 2 sets of bearing as a whole, has the assembly clearance adjustment performance is good, can be omitted, light weight, compact structure, large load capacity, for the sealed bearing prior to loading, ellipsis external wheel grease seal and from maintenance etc, and has been widely used in cars, There is also a trend of gradually expanding application in truck.

Lead Screws and Clamp Style Collars

If you have a lead screw, you’re probably interested in learning about the Acme thread on this type of shaft. You might also be interested in finding out about the Clamp style collars and Ball screw nut. But before you buy a new screw, make sure you understand what the terminology means. Here are some examples of screw shafts:

Acme thread

The standard ACME thread on a screw shaft is made of a metal that is resistant to corrosion and wear. It is used in a variety of applications. An Acme thread is available in a variety of sizes and styles. General purpose Acme threads are not designed to handle external radial loads and are supported by a shaft bearing and linear guide. Their design is intended to minimize the risk of flank wedging, which can cause friction forces and wear. The Centralizing Acme thread standard caters to applications without radial support and allows the thread to come into contact before its flanks are exposed to radial loads.
The ACME thread was first developed in 1894 for machine tools. While the acme lead screw is still the most popular screw in the US, European machines use the Trapezoidal Thread (Metric Acme). The acme thread is a stronger and more resilient alternative to square threads. It is also easier to cut than square threads and can be cut by using a single-point threading die.
Similarly to the internal threads, the metric versions of Acme are similar to their American counterparts. The only difference is that the metric threads are generally wider and are used more frequently in industrial settings. However, the metric-based screw threads are more common than their American counterparts worldwide. In addition, the Acme thread on screw shafts is used most often on external gears. But there is still a small minority of screw shafts that are made with a metric thread.
ACME screws provide a variety of advantages to users, including self-lubrication and reduced wear and tear. They are also ideal for vertical applications, where a reduced frictional force is required. In addition, ACME screws are highly resistant to back-drive and minimize the risk of backlash. Furthermore, they can be easily checked with readily available thread gauges. So, if you’re looking for a quality ACME screw for your next industrial project, look no further than ACME.
screwshaft

Lead screw coatings

The properties of lead screw materials affect their efficiency. These materials have high anti-corrosion, thermal resistance, and self-lubrication properties, which eliminates the need for lubrication. These coating materials include polytetrafluoroethylene (PFE), polyether ether ketone (PEK), and Vespel. Other desirable properties include high tensile strength, corrosion resistance, and rigidity.
The most common materials for lead screws are carbon steel, stainless steel, and aluminum. Lead screw coatings can be PTFE-based to withstand harsh environments and remove oil and grease. In addition to preventing corrosion, lead screw coatings improve the life of polymer parts. Lead screw assembly manufacturers offer a variety of customization options for their lead screw, including custom-molded nuts, thread forms, and nut bodies.
Lead screws are typically measured in rpm, or revolutions per minute. The PV curve represents the inverse relationship between contact surface pressure and sliding velocity. This value is affected by the material used in the construction of the screw, lubrication conditions, and end fixity. The critical speed of lead screws is determined by their length and minor diameter. End fixity refers to the support for the screw and affects its rigidity and critical speed.
The primary purpose of lead screws is to enable smooth movement. To achieve this, lead screws are usually preloaded with axial load, enabling consistent contact between a screw’s filets and nuts. Lead screws are often used in linear motion control systems and feature a large area of sliding contact between male and female threads. Lead screws can be manually operated or mortised and are available in a variety of sizes and materials. The materials used for lead screws include stainless steel and bronze, which are often protected by a PTFE type coating.
These screws are made of various materials, including stainless steel, bronze, and various plastics. They are also made to meet specific requirements for environmental conditions. In addition to lead screws, they can be made of stainless steel, aluminum, and carbon steel. Surface coatings can improve the screw’s corrosion resistance, while making it more wear resistant in tough environments. A screw that is coated with PTFE will maintain its anti-corrosion properties even in tough environments.
screwshaft

Clamp style collars

The screw shaft clamp style collar is a basic machine component, which is attached to the shaft via multiple screws. These collars act as mechanical stops, load bearing faces, or load transfer points. Their simple design makes them easy to install. This article will discuss the pros and cons of this style of collar. Let’s look at what you need to know before choosing a screw shaft clamp style collar. Here are some things to keep in mind.
Clamp-style shaft collars are a versatile mounting option for shafts. They have a recessed screw that fully engages the thread for secure locking. Screw shaft clamp collars come in different styles and can be used in both drive and power transmission applications. Listed below are the main differences between these 2 styles of collars. They are compatible with all types of shafts and are able to handle axial loads of up to 5500 pounds.
Clamp-style shaft collars are designed to prevent the screw from accidentally damaging the shaft when tightened. They can be tightened with a set screw to counteract the initial clamping force and prevent the shaft from coming loose. However, when tightening the screw, you should use a torque wrench. Using a set screw to tighten a screw shaft collar can cause it to warp and reduce the surface area that contacts the shaft.
Another key advantage to Clamp-style shaft collars is that they are easy to install. Clamp-style collars are available in one-piece and two-piece designs. These collars lock around the shaft and are easy to remove and install. They are ideal for virtually any shaft and can be installed without removing any components. This type of collar is also recommended for those who work on machines with sensitive components. However, be aware that the higher the OD, the more difficult it is to install and remove the collar.
Screw shaft clamp style collars are usually one-piece. A two-piece collar is easier to install than a one-piece one. The two-piece collars provide a more effective clamping force, as they use the full seating torque. Two-piece collars have the added benefit of being easy to install because they require no tools to install. You can disassemble one-piece collars before installing a two-piece collar.
screwshaft

Ball screw nut

The proper installation of a ball screw nut requires that the nut be installed on the center of the screw shaft. The return tubes of the ball nut must be oriented upward so that the ball nut will not overtravel. The adjusting nut must be tightened against a spacer or spring washer, then the nut is placed on the screw shaft. The nut should be rotated several times in both directions to ensure that it is centered.
Ball screw nuts are typically manufactured with a wide range of preloads. Large preloads are used to increase the rigidity of a ball screw assembly and prevent backlash, the lost motion caused by a clearance between the ball and nut. Using a large amount of preload can lead to excessive heat generation. The most common preload for ball screw nuts is 1 to 3%. This is usually more than enough to prevent backlash, but a higher preload will increase torque requirements.
The diameter of a ball screw is measured from its center, called the ball circle diameter. This diameter represents the distance a ball will travel during 1 rotation of the screw shaft. A smaller diameter means that there are fewer balls to carry the load. Larger leads mean longer travels per revolution and higher speeds. However, this type of screw cannot carry a greater load capacity. Increasing the length of the ball nut is not practical, due to manufacturing constraints.
The most important component of a ball screw is a ball bearing. This prevents excessive friction between the ball and the nut, which is common in lead-screw and nut combinations. Some ball screws feature preloaded balls, which avoid “wiggle” between the nut and the ball. This is particularly desirable in applications with rapidly changing loads. When this is not possible, the ball screw will experience significant backlash.
A ball screw nut can be either single or multiple circuits. Single or multiple-circuit ball nuts can be configured with 1 or 2 independent closed paths. Multi-circuit ball nuts have 2 or more circuits, making them more suitable for heavier loads. Depending on the application, a ball screw nut can be used for small clearance assemblies and compact sizes. In some cases, end caps and deflectors may be used to feed the balls back to their original position.

The Different Types of Splines in a Splined Shaft

A splined shaft is a machine component with internal and external splines. The splines are formed in 4 different ways: Involute, Parallel, Serrated, and Ball. You can learn more about each type of spline in this article. When choosing a splined shaft, be sure to choose the right 1 for your application. Read on to learn about the different types of splines and how they affect the shaft’s performance.
splineshaft

Involute splines

Involute splines in a splined shaft are used to secure and extend mechanical assemblies. They are smooth, inwardly curving grooves that resist separation during operation. A shaft with involute splines is often longer than the shaft itself. This feature allows for more axial movement. This is beneficial for many applications, especially in a gearbox.
The involute spline is a shaped spline, similar to a parallel spline. It is angled and consists of teeth that create a spiral pattern that enables linear and rotatory motion. It is distinguished from other splines by the serrations on its flanks. It also has a flat top. It is a good option for couplers and other applications where angular movement is necessary.
Involute splines are also called involute teeth because of their shape. They are flat on the top and curved on the sides. These teeth can be either internal or external. As a result, involute splines provide greater surface contact, which helps reduce stress and fatigue. Regardless of the shape, involute splines are generally easy to machine and fit.
Involute splines are a type of splines that are used in splined shafts. These splines have different names, depending on their diameters. An example set of designations is for a 32-tooth male spline, a 2,500-tooth module, and a 30 degree pressure angle. An example of a female spline, a fillet root spline, is used to describe the diameter of the splined shaft.
The effective tooth thickness of splines is dependent on the number of keyways and the type of spline. Involute splines in splined shafts should be designed to engage 25 to 50 percent of the spline teeth during the coupling. Involute splines should be able to withstand the load without cracking.

Parallel splines

Parallel splines are formed on a splined shaft by putting 1 or more teeth into another. The male spline is positioned at the center of the female spline. The teeth of the male spline are also parallel to the shaft axis, but a common misalignment causes the splines to roll and tilt. This is common in many industrial applications, and there are a number of ways to improve the performance of splines.
Typically, parallel splines are used to reduce friction in a rotating part. The splines on a splined shaft are narrower on the end face than the interior, which makes them more prone to wear. This type of spline is used in a variety of industries, such as machinery, and it also allows for greater efficiency when transmitting torque.
Involute splines on a splined shaft are the most common. They have equally spaced teeth, and are therefore less likely to crack due to fatigue. They also tend to be easy to cut and fit. However, they are not the best type of spline. It is important to understand the difference between parallel and involute splines before deciding on which spline to use.
The difference between splined and involute splines is the size of the grooves. Involute splines are generally larger than parallel splines. These types of splines provide more torque to the gear teeth and reduce stress during operation. They are also more durable and have a longer life span. And because they are used on farm machinery, they are essential in this type of application.
splineshaft

Serrated splines

A Serrated Splined Shaft has several advantages. This type of shaft is highly adjustable. Its large number of teeth allows large torques, and its shorter tooth width allows for greater adjustment. These features make this type of shaft an ideal choice for applications where accuracy is critical. Listed below are some of the benefits of this type of shaft. These benefits are just a few of the advantages. Learn more about this type of shaft.
The process of hobbing is inexpensive and highly accurate. It is useful for external spline shafts, but is not suitable for internal splines. This type of process forms synchronized shapes on the shaft, reducing the manufacturing cycle and stabilizing the relative phase between spline and thread. It uses a grinding wheel to shape the shaft. CZPT Manufacturing has a large inventory of Serrated Splined Shafts.
The teeth of a Serrated Splined Shaft are designed to engage with the hub over the entire circumference of the shaft. The teeth of the shaft are spaced uniformly around the spline, creating a multiple-tooth point of contact over the entire length of the shaft. The results of these analyses are usually satisfactory. But there are some limitations. To begin with, the splines of the Serrated Splined Shaft should be chosen carefully. If the application requires large-scale analysis, it may be necessary to modify the design.
The splines of the Serrated Splined Shaft are also used for other purposes. They can be used to transmit torque to another device. They also act as an anti-rotational device and function as a linear guide. Both the design and the type of splines determine the function of the Splined Shaft. In the automobile industry, they are used in vehicles, aerospace, earth-moving machinery, and many other industries.

Ball splines

The invention relates to a ball-spinned shaft. The shaft comprises a plurality of balls that are arranged in a series and are operatively coupled to a load path section. The balls are capable of rolling endlessly along the path. This invention also relates to a ball bearing. Here, a ball bearing is 1 of the many types of gears. The following discussion describes the features of a ball bearing.
A ball-splined shaft assembly comprises a shaft with at least 1 ball-spline groove and a plurality of circumferential step grooves. The shaft is held in a first holding means that extends longitudinally and is rotatably held by a second holding means. Both the shaft and the first holding means are driven relative to 1 another by a first driving means. It is possible to manufacture a ball-splined shaft in a variety of ways.
A ball-splined shaft features a nut with recirculating balls. The ball-splined nut rides in these grooves to provide linear motion while preventing rotation. A splined shaft with a nut that has recirculating balls can also provide rotary motion. A ball splined shaft also has higher load capacities than a ball bushing. For these reasons, ball splines are an excellent choice for many applications.
In this invention, a pair of ball-spinned shafts are housed in a box under a carrier device 40. Each of the 2 shafts extends along a longitudinal line of arm 50. One end of each shaft is supported rotatably by a slide block 56. The slide block also has a support arm 58 that supports the center arm 50 in a cantilever fashion.
splineshaft

Sector no-go gage

A no-go gauge is a tool that checks the splined shaft for oversize. It is an effective way to determine the oversize condition of a splined shaft without removing the shaft. It measures external splines and serrations. The no-go gage is available in sizes ranging from 19mm to 130mm with a 25mm profile length.
The sector no-go gage has 2 groups of diametrally opposed teeth. The space between them is manufactured to a maximum space width and the tooth thickness must be within a predetermined tolerance. This gage would be out of tolerance if the splines were measured with a pin. The dimensions of this splined shaft can be found in the respective ANSI or DIN standards.
The go-no-go gage is useful for final inspection of thread pitch diameter. It is also useful for splined shafts and threaded nuts. The thread of a screw must match the contour of the go-no-go gage head to avoid a no-go condition. There is no substitute for a quality machine. It is an essential tool for any splined shaft and fastener manufacturer.
The NO-GO gage can detect changes in tooth thickness. It can be calibrated under ISO17025 standards and has many advantages over a non-go gage. It also gives a visual reference of the thickness of a splined shaft. When the teeth match, the shaft is considered ready for installation. It is a critical process. In some cases, it is impossible to determine the precise length of the shaft spline.
The 45-degree pressure angle is most commonly used for axles and torque-delivering members. This pressure angle is the most economical in terms of tool life, but the splines will not roll neatly like a 30 degree angle. The 45-degree spline is more likely to fall off larger than the other two. Oftentimes, it will also have a crowned look. The 37.5 degree pressure angle is a compromise between the other 2 pressure angles. It is often used when the splined shaft material is harder than usual.

How to Calculate the Diameter of a Worm Gear

worm shaft
In this article, we will discuss the characteristics of the Duplex, Single-throated, and Undercut worm gears and the analysis of worm shaft deflection. Besides that, we will explore how the diameter of a worm gear is calculated. If you have any doubt about the function of a worm gear, you can refer to the table below. Also, keep in mind that a worm gear has several important parameters which determine its working.

Duplex worm gear

A duplex worm gear set is distinguished by its ability to maintain precise angles and high gear ratios. The backlash of the gearing can be readjusted several times. The axial position of the worm shaft can be determined by adjusting screws on the housing cover. This feature allows for low backlash engagement of the worm tooth pitch with the worm gear. This feature is especially beneficial when backlash is a critical factor when selecting gears.
The standard worm gear shaft requires less lubrication than its dual counterpart. Worm gears are difficult to lubricate because they are sliding rather than rotating. They also have fewer moving parts and fewer points of failure. The disadvantage of a worm gear is that you cannot reverse the direction of power due to friction between the worm and the wheel. Because of this, they are best used in machines that operate at low speeds.
Worm wheels have teeth that form a helix. This helix produces axial thrust forces, depending on the hand of the helix and the direction of rotation. To handle these forces, the worms should be mounted securely using dowel pins, step shafts, and dowel pins. To prevent the worm from shifting, the worm wheel axis must be aligned with the center of the worm wheel’s face width.
The backlash of the CZPT duplex worm gear is adjustable. By shifting the worm axially, the section of the worm with the desired tooth thickness is in contact with the wheel. As a result, the backlash is adjustable. Worm gears are an excellent choice for rotary tables, high-precision reversing applications, and ultra-low-backlash gearboxes. Axial shift backlash is a major advantage of duplex worm gears, and this feature translates into a simple and fast assembly process.
When choosing a gear set, the size and lubrication process will be crucial. If you’re not careful, you might end up with a damaged gear or 1 with improper backlash. Luckily, there are some simple ways to maintain the proper tooth contact and backlash of your worm gears, ensuring long-term reliability and performance. As with any gear set, proper lubrication will ensure your worm gears last for years to come.
worm shaft

Single-throated worm gear

Worm gears mesh by sliding and rolling motions, but sliding contact dominates at high reduction ratios. Worm gears’ efficiency is limited by the friction and heat generated during sliding, so lubrication is necessary to maintain optimal efficiency. The worm and gear are usually made of dissimilar metals, such as phosphor-bronze or hardened steel. MC nylon, a synthetic engineering plastic, is often used for the shaft.
Worm gears are highly efficient in transmission of power and are adaptable to various types of machinery and devices. Their low output speed and high torque make them a popular choice for power transmission. A single-throated worm gear is easy to assemble and lock. A double-throated worm gear requires 2 shafts, 1 for each worm gear. Both styles are efficient in high-torque applications.
Worm gears are widely used in power transmission applications because of their low speed and compact design. A numerical model was developed to calculate the quasi-static load sharing between gears and mating surfaces. The influence coefficient method allows fast computing of the deformation of the gear surface and local contact of the mating surfaces. The resultant analysis shows that a single-throated worm gear can reduce the amount of energy required to drive an electric motor.
In addition to the wear caused by friction, a worm wheel can experience additional wear. Because the worm wheel is softer than the worm, most of the wear occurs on the wheel. In fact, the number of teeth on a worm wheel should not match its thread count. A single-throated worm gear shaft can increase the efficiency of a machine by as much as 35%. In addition, it can lower the cost of running.
A worm gear is used when the diametrical pitch of the worm wheel and worm gear are the same. If the diametrical pitch of both gears is the same, the 2 worms will mesh properly. In addition, the worm wheel and worm will be attached to each other with a set screw. This screw is inserted into the hub and then secured with a locknut.

Undercut worm gear

Undercut worm gears have a cylindrical shaft, and their teeth are shaped in an evolution-like pattern. Worms are made of a hardened cemented metal, 16MnCr5. The number of gear teeth is determined by the pressure angle at the zero gearing correction. The teeth are convex in normal and centre-line sections. The diameter of the worm is determined by the worm’s tangential profile, d1. Undercut worm gears are used when the number of teeth in the cylinder is large, and when the shaft is rigid enough to resist excessive load.
The center-line distance of the worm gears is the distance from the worm centre to the outer diameter. This distance affects the worm’s deflection and its safety. Enter a specific value for the bearing distance. Then, the software proposes a range of suitable solutions based on the number of teeth and the module. The table of solutions contains various options, and the selected variant is transferred to the main calculation.
A pressure-angle-angle-compensated worm can be manufactured using single-pointed lathe tools or end mills. The worm’s diameter and depth are influenced by the cutter used. In addition, the diameter of the grinding wheel determines the profile of the worm. If the worm is cut too deep, it will result in undercutting. Despite the undercutting risk, the design of worm gearing is flexible and allows considerable freedom.
The reduction ratio of a worm gear is massive. With only a little effort, the worm gear can significantly reduce speed and torque. In contrast, conventional gear sets need to make multiple reductions to get the same reduction level. Worm gears also have several disadvantages. Worm gears can’t reverse the direction of power because the friction between the worm and the wheel makes this impossible. The worm gear can’t reverse the direction of power, but the worm moves from 1 direction to another.
The process of undercutting is closely related to the profile of the worm. The worm’s profile will vary depending on the worm diameter, lead angle, and grinding wheel diameter. The worm’s profile will change if the generating process has removed material from the tooth base. A small undercut reduces tooth strength and reduces contact. For smaller gears, a minimum of 14-1/2degPA gears should be used.

Analysis of worm shaft deflection

To analyze the worm shaft deflection, we first derived its maximum deflection value. The deflection is calculated using the Euler-Bernoulli method and Timoshenko shear deformation. Then, we calculated the moment of inertia and the area of the transverse section using CAD software. In our analysis, we used the results of the test to compare the resulting parameters with the theoretical ones.
We can use the resulting centre-line distance and worm gear tooth profiles to calculate the required worm deflection. Using these values, we can use the worm gear deflection analysis to ensure the correct bearing size and worm gear teeth. Once we have these values, we can transfer them to the main calculation. Then, we can calculate the worm deflection and its safety. Then, we enter the values into the appropriate tables, and the resulting solutions are automatically transferred into the main calculation. However, we have to keep in mind that the deflection value will not be considered safe if it is larger than the worm gear’s outer diameter.
We use a four-stage process for investigating worm shaft deflection. We first apply the finite element method to compute the deflection and compare the simulation results with the experimentally tested worm shafts. Finally, we perform parameter studies with 15 worm gear toothings without considering the shaft geometry. This step is the first of 4 stages of the investigation. Once we have calculated the deflection, we can use the simulation results to determine the parameters needed to optimize the design.
Using a calculation system to calculate worm shaft deflection, we can determine the efficiency of worm gears. There are several parameters to optimize gearing efficiency, including material and geometry, and lubricant. In addition, we can reduce the bearing losses, which are caused by bearing failures. We can also identify the supporting method for the worm shafts in the options menu. The theoretical section provides further information.

Calculating the Deflection of a Worm Shaft

In this article, we’ll discuss how to calculate the deflection of a worm gear’s worm shaft. We’ll also discuss the characteristics of a worm gear, including its tooth forces. And we’ll cover the important characteristics of a worm gear. Read on to learn more! Here are some things to consider before purchasing a worm gear. We hope you enjoy learning! After reading this article, you’ll be well-equipped to choose a worm gear to match your needs.

Calculation of worm shaft deflection

The main goal of the calculations is to determine the deflection of a worm. Worms are used to turn gears and mechanical devices. This type of transmission uses a worm. The worm diameter and the number of teeth are inputted into the calculation gradually. Then, a table with proper solutions is shown on the screen. After completing the table, you can then move on to the main calculation. You can change the strength parameters as well.
The maximum worm shaft deflection is calculated using the finite element method (FEM). The model has many parameters, including the size of the elements and boundary conditions. The results from these simulations are compared to the corresponding analytical values to calculate the maximum deflection. The result is a table that displays the maximum worm shaft deflection. The tables can be downloaded below. You can also find more information about the different deflection formulas and their applications.
The calculation method used by DIN EN 10084 is based on the hardened cemented worm of 16MnCr5. Then, you can use DIN EN 10084 (CuSn12Ni2-C-GZ) and DIN EN 1982 (CuAl10Fe5Ne5-C-GZ). Then, you can enter the worm face width, either manually or using the auto-suggest option.
Common methods for the calculation of worm shaft deflection provide a good approximation of deflection but do not account for geometric modifications on the worm. While Norgauer’s 2021 approach addresses these issues, it fails to account for the helical winding of the worm teeth and overestimates the stiffening effect of gearing. More sophisticated approaches are required for the efficient design of thin worm shafts.
Worm gears have a low noise and vibration compared to other types of mechanical devices. However, worm gears are often limited by the amount of wear that occurs on the softer worm wheel. Worm shaft deflection is a significant influencing factor for noise and wear. The calculation method for worm gear deflection is available in ISO/TR 14521, DIN 3996, and AGMA 6022.
The worm gear can be designed with a precise transmission ratio. The calculation involves dividing the transmission ratio between more stages in a gearbox. Power transmission input parameters affect the gearing properties, as well as the material of the worm/gear. To achieve a better efficiency, the worm/gear material should match the conditions that are to be experienced. The worm gear can be a self-locking transmission.
The worm gearbox contains several machine elements. The main contributors to the total power loss are the axial loads and bearing losses on the worm shaft. Hence, different bearing configurations are studied. One type includes locating/non-locating bearing arrangements. The other is tapered roller bearings. The worm gear drives are considered when locating versus non-locating bearings. The analysis of worm gear drives is also an investigation of the X-arrangement and four-point contact bearings.

Influence of tooth forces on bending stiffness of a worm gear

The bending stiffness of a worm gear is dependent on tooth forces. Tooth forces increase as the power density increases, but this also leads to increased worm shaft deflection. The resulting deflection can affect efficiency, wear load capacity, and NVH behavior. Continuous improvements in bronze materials, lubricants, and manufacturing quality have enabled worm gear manufacturers to produce increasingly high power densities.
Standardized calculation methods take into account the supporting effect of the toothing on the worm shaft. However, overhung worm gears are not included in the calculation. In addition, the toothing area is not taken into account unless the shaft is designed next to the worm gear. Similarly, the root diameter is treated as the equivalent bending diameter, but this ignores the supporting effect of the worm toothing.
A generalized formula is provided to estimate the STE contribution to vibratory excitation. The results are applicable to any gear with a meshing pattern. It is recommended that engineers test different meshing methods to obtain more accurate results. One way to test tooth-meshing surfaces is to use a finite element stress and mesh subprogram. This software will measure tooth-bending stresses under dynamic loads.
The effect of tooth-brushing and lubricant on bending stiffness can be achieved by increasing the pressure angle of the worm pair. This can reduce tooth bending stresses in the worm gear. A further method is to add a load-loaded tooth-contact analysis (CCTA). This is also used to analyze mismatched ZC1 worm drive. The results obtained with the technique have been widely applied to various types of gearing.
In this study, we found that the ring gear’s bending stiffness is highly influenced by the teeth. The chamfered root of the ring gear is larger than the slot width. Thus, the ring gear’s bending stiffness varies with its tooth width, which increases with the ring wall thickness. Furthermore, a variation in the ring wall thickness of the worm gear causes a greater deviation from the design specification.
To understand the impact of the teeth on the bending stiffness of a worm gear, it is important to know the root shape. Involute teeth are susceptible to bending stress and can break under extreme conditions. A tooth-breakage analysis can control this by determining the root shape and the bending stiffness. The optimization of the root shape directly on the final gear minimizes the bending stress in the involute teeth.
The influence of tooth forces on the bending stiffness of a worm gear was investigated using the CZPT Spiral Bevel Gear Test Facility. In this study, multiple teeth of a spiral bevel pinion were instrumented with strain gages and tested at speeds ranging from static to 14400 RPM. The tests were performed with power levels as high as 540 kW. The results obtained were compared with the analysis of a three-dimensional finite element model.

Characteristics of worm gears

Worm gears are unique types of gears. They feature a variety of characteristics and applications. This article will examine the characteristics and benefits of worm gears. Then, we’ll examine the common applications of worm gears. Let’s take a look! Before we dive in to worm gears, let’s review their capabilities. Hopefully, you’ll see how versatile these gears are.
A worm gear can achieve massive reduction ratios with little effort. By adding circumference to the wheel, the worm can greatly increase its torque and decrease its speed. Conventional gearsets require multiple reductions to achieve the same reduction ratio. Worm gears have fewer moving parts, so there are fewer places for failure. However, they can’t reverse the direction of power. This is because the friction between the worm and wheel makes it impossible to move the worm backwards.
Worm gears are widely used in elevators, hoists, and lifts. They are particularly useful in applications where stopping speed is critical. They can be incorporated with smaller brakes to ensure safety, but shouldn’t be relied upon as a primary braking system. Generally, they are self-locking, so they are a good choice for many applications. They also have many benefits, including increased efficiency and safety.
Worm gears are designed to achieve a specific reduction ratio. They are typically arranged between the input and output shafts of a motor and a load. The 2 shafts are often positioned at an angle that ensures proper alignment. Worm gear gears have a center spacing of a frame size. The center spacing of the gear and worm shaft determines the axial pitch. For instance, if the gearsets are set at a radial distance, a smaller outer diameter is necessary.
Worm gears’ sliding contact reduces efficiency. But it also ensures quiet operation. The sliding action limits the efficiency of worm gears to 30% to 50%. A few techniques are introduced herein to minimize friction and to produce good entrance and exit gaps. You’ll soon see why they’re such a versatile choice for your needs! So, if you’re considering purchasing a worm gear, make sure you read this article to learn more about its characteristics!
An embodiment of a worm gear is described in FIGS. 19 and 20. An alternate embodiment of the system uses a single motor and a single worm 153. The worm 153 turns a gear which drives an arm 152. The arm 152, in turn, moves the lens/mirr assembly 10 by varying the elevation angle. The motor control unit 114 then tracks the elevation angle of the lens/mirr assembly 10 in relation to the reference position.
The worm wheel and worm are both made of metal. However, the brass worm and wheel are made of brass, which is a yellow metal. Their lubricant selections are more flexible, but they’re limited by additive restrictions due to their yellow metal. Plastic on metal worm gears are generally found in light load applications. The lubricant used depends on the type of plastic, as many types of plastics react to hydrocarbons found in regular lubricant. For this reason, you need a non-reactive lubricant.
