Types of Splines

There are four types of splines: Involute, Parallel key, helical, and ball. Learn about their characteristics. And, if you’re not sure what they are, you can always request a quotation. These splines are commonly used for building special machinery, repair jobs, and other applications. The CZPT Manufacturing Company manufactures these shafts. It is a specialty manufacturer and we welcome your business.
splineshaft

Involute splines

The involute spline provides a more rigid and durable structure, and is available in a variety of diameters and spline counts. Generally, steel, carbon steel, or titanium are used as raw materials. Other materials, such as carbon fiber, may be suitable. However, titanium can be difficult to produce, so some manufacturers make splines using other constituents.
When splines are used in shafts, they prevent parts from separating during operation. These features make them an ideal choice for securing mechanical assemblies. Splines with inward-curving grooves do not have sharp corners and are therefore less likely to break or separate while they are in operation. These properties help them to withstand high-speed operations, such as braking, accelerating, and reversing.
A male spline is fitted with an externally-oriented face, and a female spline is inserted through the center. The teeth of the male spline typically have chamfered tips to provide clearance with the transition area. The radii and width of the teeth of a male spline are typically larger than those of a female spline. These specifications are specified in ANSI or DIN design manuals.
The effective tooth thickness of a spline depends on the involute profile error and the lead error. Also, the spacing of the spline teeth and keyways can affect the effective tooth thickness. Involute splines in a splined shaft are designed so that at least 25 percent of the spline teeth engage during coupling, which results in a uniform distribution of load and wear on the spline.

Parallel key splines

A parallel splined shaft has a helix of equal-sized grooves around its circumference. These grooves are generally parallel or involute. Splines minimize stress concentrations in stationary joints and allow linear and rotary motion. Splines may be cut or cold-rolled. Cold-rolled splines have more strength than cut spines and are often used in applications that require high strength, accuracy, and a smooth surface.
A parallel key splined shaft features grooves and keys that are parallel to the axis of the shaft. This design is best suited for applications where load bearing is a primary concern and a smooth motion is needed. A parallel key splined shaft can be made from alloy steels, which are iron-based alloys that may also contain chromium, nickel, molybdenum, copper, or other alloying materials.
A splined shaft can be used to transmit torque and provide anti-rotation when operating as a linear guide. These shafts have square profiles that match up with grooves in a mating piece and transmit torque and rotation. They can also be easily changed in length, and are commonly used in aerospace. Its reliability and fatigue life make it an excellent choice for many applications.
The main difference between a parallel key splined shaft and a keyed shaft is that the former offers more flexibility. They lack slots, which reduce torque-transmitting capacity. Splines offer equal load distribution along the gear teeth, which translates into a longer fatigue life for the shaft. In agricultural applications, shaft life is essential. Agricultural equipment, for example, requires the ability to function at high speeds for extended periods of time.
splineshaft

Involute helical splines

Involute splines are a common design for splined shafts. They are the most commonly used type of splined shaft and feature equal spacing among their teeth. The teeth of this design are also shorter than those of the parallel spline shaft, reducing stress concentration. These splines can be used to transmit power to floating or permanently fixed gears, and reduce stress concentrations in the stationary joint. Involute splines are the most common type of splined shaft, and are widely used for a variety of applications in automotive, machine tools, and more.
Involute helical spline shafts are ideal for applications involving axial motion and rotation. They allow for face coupling engagement and disengagement. This design also allows for a larger diameter than a parallel spline shaft. The result is a highly efficient gearbox. Besides being durable, splines can also be used for other applications involving torque and energy transfer.
A new statistical model can be used to determine the number of teeth that engage for a given load. These splines are characterized by a tight fit at the major diameters, thereby transferring concentricity from the shaft to the female spline. A male spline has chamfered tips for clearance with the transition area. ANSI and DIN design manuals specify the different classes of fit.
The design of involute helical splines is similar to that of gears, and their ridges or teeth are matched with the corresponding grooves in a mating piece. It enables torque and rotation to be transferred to a mate piece while maintaining alignment of the two components. Different types of splines are used in different applications. Different splines can have different levels of tooth height.

Involute ball splines

When splines are used, they allow the shaft and hub to engage evenly over the shaft’s entire circumference. Because the teeth are evenly spaced, the load that they can transfer is uniform and their position is always the same regardless of shaft length. Whether the shaft is used to transmit torque or to transmit power, splines are a great choice. They provide maximum strength and allow for linear or rotary motion.
There are three basic types of splines: helical, crown, and ball. Crown splines feature equally spaced grooves. Crown splines feature involute sides and parallel sides. Helical splines use involute teeth and are often used in small diameter shafts. Ball splines contain a ball bearing inside the splined shaft to facilitate rotary motion and minimize stress concentration in stationary joints.
The two types of splines are classified under the ANSI classes of fit. Fillet root splines have teeth that mesh along the longitudinal axis of rotation. Flat root splines have similar teeth, but are intended to optimize strength for short-term use. Both types of splines are important for ensuring the shaft aligns properly and is not misaligned.
The friction coefficient of the hub is a complex process. When the hub is off-center, the center moves in predictable but irregular motion. Moreover, when the shaft is centered, the center may oscillate between being centered and being off-center. To compensate for this, the torque must be adequate to keep the shaft in its axis during all rotation angles. While straight-sided splines provide similar centering, they have lower misalignment load factors.
splineshaft

Keyed shafts

Essentially, splined shafts have teeth or ridges that fit together to transfer torque. Because splines are not as tall as involute gears, they offer uniform torque transfer. Additionally, they provide the opportunity for torque and rotational changes and improve wear resistance. In addition to their durability, splined shafts are popular in the aerospace industry and provide increased reliability and fatigue life.
Keyed shafts are available in different materials, lengths, and diameters. When used in high-power drive applications, they offer higher torque and rotational speeds. The higher torque they produce helps them deliver power to the gearbox. However, they are not as durable as splined shafts, which is why the latter is usually preferred in these applications. And while they’re more expensive, they’re equally effective when it comes to torque delivery.
Parallel keyed shafts have separate profiles and ridges and are used in applications requiring accuracy and precision. Keyed shafts with rolled splines are 35% stronger than cut splines and are used where precision is essential. These splines also have a smooth finish, which can make them a good choice for precision applications. They also work well with gears and other mechanical systems that require accurate torque transfer.
Carbon steel is another material used for splined shafts. Carbon steel is known for its malleability, and its shallow carbon content helps create reliable motion. However, if you’re looking for something more durable, consider ferrous steel. This type contains metals such as nickel, chromium, and molybdenum. And it’s important to remember that carbon steel is not the only material to consider.

The Benefits of Spline Couplings for Disc Brake Mounting Interfaces

Spline couplings are commonly used for securing disc brake mounting interfaces. Spline couplings are often used in high-performance vehicles, aeronautics, and many other applications. However, the mechanical benefits of splines are not immediately obvious. Listed below are the benefits of spline couplings. We’ll discuss what these advantages mean for you. Read on to discover how these couplings work.

Disc brake mounting interfaces are splined

There are two common disc brake mounting interfaces – splined and six-bolt. Splined rotors fit on splined hubs; six-bolt rotors will need an adapter to fit on six-bolt hubs. The six-bolt method is easier to maintain and may be preferred by many cyclists. If you’re thinking of installing a disc brake system, it is important to know how to choose the right splined and center lock interfaces.
splineshaft

Aerospace applications

The splines used for spline coupling in aircraft are highly complex. While some previous researches have addressed the design of splines, few publications have tackled the problem of misaligned spline coupling. Nevertheless, the accurate results we obtained were obtained using dedicated simulation tools, which are not commercially available. Nevertheless, such tools can provide a useful reference for our approach. It would be beneficial if designers could use simple tools for evaluating contact pressure peaks. Our analytical approach makes it possible to find answers to such questions.
The design of a spline coupling for aerospace applications must be accurate to minimize weight and prevent failure mechanisms. In addition to weight reduction, it is necessary to minimize fretting fatigue. The pressure distribution on the spline coupling teeth is a significant factor in determining its fretting fatigue. Therefore, we use analytical and experimental methods to examine the contact pressure distribution in the axial direction of spline couplings.
The teeth of a spline coupling can be categorized by the type of engagement they provide. This study investigates the position of resultant contact forces in the teeth of a spline coupling when applied to pitch diameter. Using FEM models, numerical results are generated for nominal and parallel offset misalignments. The axial tooth profile determines the behavior of the coupling component and its ability to resist wear. Angular misalignment is also a concern, causing misalignment.
In order to assess wear damage of a spline coupling, we must take into consideration the impact of fretting on the components. This wear is caused by relative motion between the teeth that engage them. The misalignment may be caused by vibrations, cyclical tooth deflection, or angular misalignment. The result of this analysis may help designers improve their spline coupling designs and develop improved performance.
CZPT polyimide, an abrasion-resistant polymer, is a popular choice for high-temperature spline couplings. This material reduces friction and wear, provides a low friction surface, and has a low wear rate. Furthermore, it offers up to 50 times the life of metal on metal spline connections. For these reasons, it is important to choose the right material for your spline coupling.
splineshaft

High-performance vehicles

A spline coupler is a device used to connect splined shafts. A typical spline coupler resembles a short pipe with splines on either end. There are two basic types of spline coupling: single and dual spline. One type attaches to a drive shaft, while the other attaches to the gearbox. While spline couplings are typically used in racing, they’re also used for performance problems.
The key challenge in spline couplings is to determine the optimal dimension of spline joints. This is difficult because no commercial codes allow the simulation of misaligned joints, which can destroy components. This article presents analytical approaches to estimating contact pressures in spline connections. The results are comparable with numerical approaches but require special codes to accurately model the coupling operation. This research highlights several important issues and aims to make the application of spline couplings in high-performance vehicles easier.
The stiffness of spline assemblies can be calculated using tooth-like structures. Such splines can be incorporated into the spline joint to produce global stiffness for torsional vibration analysis. Bearing reactions are calculated for a certain level of misalignment. This information can be used to design bearing dimensions and correct misalignment. There are three types of spline couplings.
Major diameter fit splines are made with tightly controlled outside diameters. This close fit provides concentricity transfer from the male to the female spline. The teeth of the male spline usually have chamfered tips and clearance with fillet radii. These splines are often manufactured from billet steel or aluminum. These materials are renowned for their strength and uniform grain created by the forging process. ANSI and DIN design manuals define classes of fit.
splineshaft

Disc brake mounting interfaces

A spline coupling for disc brake mounting interfaces is a type of hub-to-brake-disc mount. It is a highly durable coupling mechanism that reduces heat transfer from the disc to the axle hub. The mounting arrangement also isolates the axle hub from direct contact with the disc. It is also designed to minimize the amount of vehicle downtime and maintenance required to maintain proper alignment.
Disc brakes typically have substantial metal-to-metal contact with axle hub splines. The discs are held in place on the hub by intermediate inserts. This metal-to-metal contact also aids in the transfer of brake heat from the brake disc to the axle hub. Spline coupling for disc brake mounting interfaces comprises a mounting ring that is either a threaded or non-threaded spline.
During drag brake experiments, perforated friction blocks filled with various additive materials are introduced. The materials included include Cu-based powder metallurgy material, a composite material, and a Mn-Cu damping alloy. The filling material affects the braking interface’s wear behavior and friction-induced vibration characteristics. Different filling materials produce different types of wear debris and have different wear evolutions. They also differ in their surface morphology.
Disc brake couplings are usually made of two different types. The plain and HD versions are interchangeable. The plain version is the simplest to install, while the HD version has multiple components. The two-piece couplings are often installed at the same time, but with different mounting interfaces. You should make sure to purchase the appropriate coupling for your vehicle. These interfaces are a vital component of your vehicle and must be installed correctly for proper operation.
Disc brakes use disc-to-hub elements that help locate the forces and displace them to the rim. These elements are typically made of stainless steel, which increases the cost of manufacturing the disc brake mounting interface. Despite their benefits, however, the high braking force loads they endure are hard on the materials. Moreover, excessive heat transferred to the intermediate elements can adversely affect the fatigue life and long-term strength of the brake system.

Applications of Spline Couplings

A spline coupling is a highly effective means of connecting two or more components. These types of couplings are very efficient, as they combine linear motion with rotation, and their efficiency makes them a desirable choice in numerous applications. Read on to learn more about the main characteristics and applications of spline couplings. You will also be able to determine the predicted operation and wear. You can easily design your own couplings by following the steps outlined below.
splineshaft

Optimal design

The spline coupling plays an important role in transmitting torque. It consists of a hub and a shaft with splines that are in surface contact without relative motion. Because they are connected, their angular velocity is the same. The splines can be designed with any profile that minimizes friction. Because they are in contact with each other, the load is not evenly distributed, concentrating on a small area, which can deform the hub surface.
Optimal spline coupling design takes into account several factors, including weight, material characteristics, and performance requirements. In the aeronautics industry, weight is an important design factor. S.A.E. and ANSI tables do not account for weight when calculating the performance requirements of spline couplings. Another critical factor is space. Spline couplings may need to fit in tight spaces, or they may be subject to other configuration constraints.
Optimal design of spline couplers may be characterized by an odd number of teeth. However, this is not always the case. If the external spline’s outer diameter exceeds a certain threshold, the optimal spline coupling model may not be an optimal choice for this application. To optimize a spline coupling for a specific application, the user may need to consider the sizing method that is most appropriate for their application.
Once a design is generated, the next step is to test the resulting spline coupling. The system must check for any design constraints and validate that it can be produced using modern manufacturing techniques. The resulting spline coupling model is then exported to an optimisation tool for further analysis. The method enables a designer to easily manipulate the design of a spline coupling and reduce its weight.
The spline coupling model 20 includes the major structural features of a spline coupling. A product model software program 10 stores default values for each of the spline coupling’s specifications. The resulting spline model is then calculated in accordance with the algorithm used in the present invention. The software allows the designer to enter the spline coupling’s radii, thickness, and orientation.
splineshaft

Characteristics

An important aspect of aero-engine splines is the load distribution among the teeth. The researchers have performed experimental tests and have analyzed the effect of lubrication conditions on the coupling behavior. Then, they devised a theoretical model using a Ruiz parameter to simulate the actual working conditions of spline couplings. This model explains the wear damage caused by the spline couplings by considering the influence of friction, misalignment, and other conditions that are relevant to the splines’ performance.
In order to design a spline coupling, the user first inputs the design criteria for sizing load carrying sections, including the external spline 40 of the spline coupling model 30. Then, the user specifies torque margin performance requirement specifications, such as the yield limit, plastic buckling, and creep buckling. The software program then automatically calculates the size and configuration of the load carrying sections and the shaft. These specifications are then entered into the model software program 10 as specification values.
Various spline coupling configuration specifications are input on the GUI screen 80. The software program 10 then generates a spline coupling model by storing default values for the various specifications. The user then can manipulate the spline coupling model by modifying its various specifications. The final result will be a computer-aided design that enables designers to optimize spline couplings based on their performance and design specifications.
The spline coupling model software program continually evaluates the validity of spline coupling models for a particular application. For example, if a user enters a data value signal corresponding to a parameter signal, the software compares the value of the signal entered to the corresponding value in the knowledge base. If the values are outside the specifications, a warning message is displayed. Once this comparison is completed, the spline coupling model software program outputs a report with the results.
Various spline coupling design factors include weight, material properties, and performance requirements. Weight is one of the most important design factors, particularly in the aeronautics field. ANSI and S.A.E. tables do not consider these factors when calculating the load characteristics of spline couplings. Other design requirements may also restrict the configuration of a spline coupling.

Applications

Spline couplings are a type of mechanical joint that connects two rotating shafts. Its two parts engage teeth that transfer load. Although splines are commonly over-dimensioned, they are still prone to fatigue and static behavior. These properties also make them prone to wear and tear. Therefore, proper design and selection are vital to minimize wear and tear on splines. There are many applications of spline couplings.
A key design is based on the size of the shaft being joined. This allows for the proper spacing of the keys. A novel method of hobbing allows for the formation of tapered bases without interference, and the root of the keys is concentric with the axis. These features enable for high production rates. Various applications of spline couplings can be found in various industries. To learn more, read on.
FE based methodology can predict the wear rate of spline couplings by including the evolution of the coefficient of friction. This method can predict fretting wear from simple round-on-flat geometry, and has been calibrated with experimental data. The predicted wear rate is reasonable compared to the experimental data. Friction evolution in spline couplings depends on the spline geometry. It is also crucial to consider the lubrication condition of the splines.
Using a spline coupling reduces backlash and ensures proper alignment of mated components. The shaft’s splined tooth form transfers rotation from the splined shaft to the internal splined member, which may be a gear or other rotary device. A spline coupling’s root strength and torque requirements determine the type of spline coupling that should be used.
The spline root is usually flat and has a crown on one side. The crowned spline has a symmetrical crown at the centerline of the face-width of the spline. As the spline length decreases toward the ends, the teeth are becoming thinner. The tooth diameter is measured in pitch. This means that the male spline has a flat root and a crowned spline.
splineshaft

Predictability

Spindle couplings are used in rotating machinery to connect two shafts. They are composed of two parts with teeth that engage each other and transfer load. Spline couplings are commonly over-dimensioned and are prone to static and fatigue behavior. Wear phenomena are also a common problem with splines. To address these issues, it is essential to understand the behavior and predictability of these couplings.
Dynamic behavior of spline-rotor couplings is often unclear, particularly if the system is not integrated with the rotor. For example, when a misalignment is not present, the main response frequency is one X-rotating speed. As the misalignment increases, the system starts to vibrate in complex ways. Furthermore, as the shaft orbits depart from the origin, the magnitudes of all the frequencies increase. Thus, research results are useful in determining proper design and troubleshooting of rotor systems.
The model of misaligned spline couplings can be obtained by analyzing the stress-compression relationships between two spline pairs. The meshing force model of splines is a function of the system mass, transmitting torque, and dynamic vibration displacement. This model holds when the dynamic vibration displacement is small. Besides, the CZPT stepping integration method is stable and has high efficiency.
The slip distributions are a function of the state of lubrication, coefficient of friction, and loading cycles. The predicted wear depths are well within the range of measured values. These predictions are based on the slip distributions. The methodology predicts increased wear under lightly lubricated conditions, but not under added lubrication. The lubrication condition and coefficient of friction are the key factors determining the wear behavior of splines.

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.

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 four 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 three 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 two 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 two 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 one another.
