Worm Gear Motors

Worm gear motors are often preferred for quieter operation because of the smooth sliding motion of the worm shaft. Unlike gear motors with teeth, which may click as the worm turns, worm gear motors can be installed in a quiet area. In this article, we will talk about the CZPT whirling process and the various types of worms available. We’ll also discuss the benefits of worm gear motors and worm wheel.
worm shaft

worm gear

In the case of a worm gear, the axial pitch of the ring pinion of the corresponding revolving worm is equal to the circular pitch of the mating revolving pinion of the worm gear. A worm with 1 start is known as a worm with a lead. This leads to a smaller worm wheel. Worms can work in tight spaces because of their small profile.
Generally, a worm gear has high efficiency, but there are a few disadvantages. Worm gears are not recommended for high-heat applications because of their high level of rubbing. A full-fluid lubricant film and the low wear level of the gear reduce friction and wear. Worm gears also have a lower wear rate than a standard gear. The worm shaft and worm gear is also more efficient than a standard gear.
The worm gear shaft is cradled within a self-aligning bearing block that is attached to the gearbox casing. The eccentric housing has radial bearings on both ends, enabling it to engage with the worm gear wheel. The drive is transferred to the worm gear shaft through bevel gears 13A, 1 fixed at the ends of the worm gear shaft and the other in the center of the cross-shaft.

worm wheel

In a worm gearbox, the pinion or worm gear is centered between a geared cylinder and a worm shaft. The worm gear shaft is supported at either end by a radial thrust bearing. A gearbox’s cross-shaft is fixed to a suitable drive means and pivotally attached to the worm wheel. The input drive is transferred to the worm gear shaft 10 through bevel gears 13A, 1 of which is fixed to the end of the worm gear shaft and the other at the centre of the cross-shaft.
Worms and worm wheels are available in several materials. The worm wheel is made of bronze alloy, aluminum, or steel. Aluminum bronze worm wheels are a good choice for high-speed applications. Cast iron worm wheels are cheap and suitable for light loads. MC nylon worm wheels are highly wear-resistant and machinable. Aluminum bronze worm wheels are available and are good for applications with severe wear conditions.
When designing a worm wheel, it is vital to determine the correct lubricant for the worm shaft and a corresponding worm wheel. A suitable lubricant should have a kinematic viscosity of 300 mm2/s and be used for worm wheel sleeve bearings. The worm wheel and worm shaft should be properly lubricated to ensure their longevity.

Multi-start worms

A multi-start worm gear screw jack combines the benefits of multiple starts with linear output speeds. The multi-start worm shaft reduces the effects of single start worms and large ratio gears. Both types of worm gears have a reversible worm that can be reversed or stopped by hand, depending on the application. The worm gear’s self-locking ability depends on the lead angle, pressure angle, and friction coefficient.
A single-start worm has a single thread running the length of its shaft. The worm advances 1 tooth per revolution. A multi-start worm has multiple threads in each of its threads. The gear reduction on a multi-start worm is equal to the number of teeth on the gear minus the number of starts on the worm shaft. In general, a multi-start worm has 2 or 3 threads.
Worm gears can be quieter than other types of gears because the worm shaft glides rather than clicking. This makes them an excellent choice for applications where noise is a concern. Worm gears can be made of softer material, making them more noise-tolerant. In addition, they can withstand shock loads. Compared to gears with toothed teeth, worm gears have a lower noise and vibration rate.
worm shaft

CZPT whirling process

The CZPT whirling process for worm shafts raises the bar for precision gear machining in small to medium production volumes. The CZPT whirling process reduces thread rolling, increases worm quality, and offers reduced cycle times. The CZPT LWN-90 whirling machine features a steel bed, programmable force tailstock, and five-axis interpolation for increased accuracy and quality.
Its 4,000-rpm, 5-kW whirling spindle produces worms and various types of screws. Its outer diameters are up to 2.5 inches, while its length is up to 20 inches. Its dry-cutting process uses a vortex tube to deliver chilled compressed air to the cutting point. Oil is also added to the mixture. The worm shafts produced are free of undercuts, reducing the amount of machining required.
Induction hardening is a process that takes advantage of the whirling process. The induction hardening process utilizes alternating current (AC) to cause eddy currents in metallic objects. The higher the frequency, the higher the surface temperature. The electrical frequency is monitored through sensors to prevent overheating. Induction heating is programmable so that only certain parts of the worm shaft will harden.

Common tangent at an arbitrary point on both surfaces of the worm wheel

A worm gear consists of 2 helical segments with a helix angle equal to 90 degrees. This shape allows the worm to rotate with more than 1 tooth per rotation. A worm’s helix angle is usually close to 90 degrees and the body length is fairly long in the axial direction. A worm gear with a lead angle g has similar properties as a screw gear with a helix angle of 90 degrees.
The axial cross section of a worm gear is not conventionally trapezoidal. Instead, the linear part of the oblique side is replaced by cycloid curves. These curves have a common tangent near the pitch line. The worm wheel is then formed by gear cutting, resulting in a gear with 2 meshing surfaces. This worm gear can rotate at high speeds and still operate quietly.
A worm wheel with a cycloid pitch is a more efficient worm gear. It reduces friction between the worm and the gear, resulting in greater durability, improved operating efficiency, and reduced noise. This pitch line also helps the worm wheel engage more evenly and smoothly. Moreover, it prevents interference with their appearance. It also makes worm wheel and gear engagement smoother.
worm shaft

Calculation of worm shaft deflection

There are several methods for calculating worm shaft deflection, and each method has its own set of disadvantages. These commonly used methods provide good approximations but are inadequate for determining the actual worm shaft deflection. For example, these methods do not account for the geometric modifications to the worm, such as its helical winding of teeth. Furthermore, they overestimate the stiffening effect of the gearing. Hence, efficient thin worm shaft designs require other approaches.
Fortunately, several methods exist to determine the maximum worm shaft deflection. These methods use the finite element method, and include boundary conditions and parameter calculations. Here, we look at a couple of methods. The first method, DIN 3996, calculates the maximum worm shaft deflection based on the test results, while the second one, AGMA 6022, uses the root diameter of the worm as the equivalent bending diameter.
The second method focuses on the basic parameters of worm gearing. We’ll take a closer look at each. We’ll examine worm gearing teeth and the geometric factors that influence them. Commonly, the range of worm gearing teeth is 1 to four, but it can be as large as twelve. Choosing the teeth should depend on optimization requirements, including efficiency and weight. For example, if a worm gearing needs to be smaller than the previous model, then a small number of teeth will suffice.

Analytical Approaches to Estimating Contact Pressures in Spline Couplings

A spline coupling is a type of mechanical connection between 2 rotating shafts. It consists of 2 parts – a coupler and a coupling. Both parts have teeth which engage and transfer loads. However, spline couplings are typically over-dimensioned, which makes them susceptible to fatigue and static behavior. Wear phenomena can also cause the coupling to fail. For this reason, proper spline coupling design is essential for achieving optimum performance.

Modeling a spline coupling

Spline couplings are becoming increasingly popular in the aerospace industry, but they operate in a slightly misaligned state, causing both vibrations and damage to the contact surfaces. To solve this problem, this article offers analytical approaches for estimating the contact pressures in a spline coupling. Specifically, this article compares analytical approaches with pure numerical approaches to demonstrate the benefits of an analytical approach.
To model a spline coupling, first you create the knowledge base for the spline coupling. The knowledge base includes a large number of possible specification values, which are related to each other. If you modify 1 specification, it may lead to a warning for violating another. To make the design valid, you must create a spline coupling model that meets the specified specification values.
After you have modeled the geometry, you must enter the contact pressures of the 2 spline couplings. Then, you need to determine the position of the pitch circle of the spline. In Figure 2, the centre of the male coupling is superposed to that of the female spline. Then, you need to make sure that the alignment meshing distance of the 2 splines is the same.
Once you have the data you need to create a spline coupling model, you can begin by entering the specifications for the interface design. Once you have this data, you need to choose whether to optimize the internal spline or the external spline. You’ll also need to specify the tooth friction coefficient, which is used to determine the stresses in the spline coupling model 20. You should also enter the pilot clearance, which is the clearance between the tip 186 of a tooth 32 on 1 spline and the feature on the mating spline.
After you have entered the desired specifications for the external spline, you can enter the parameters for the internal spline. For example, you can enter the outer diameter limit 154 of the major snap 54 and the minor snap 56 of the internal spline. The values of these parameters are displayed in color-coded boxes on the Spline Inputs and Configuration GUI screen 80. Once the parameters are entered, you’ll be presented with a geometric representation of the spline coupling model 20.

Creating a spline coupling model 20

The spline coupling model 20 is created by a product model software program 10. The software validates the spline coupling model against a knowledge base of configuration-dependent specification constraints and relationships. This report is then input to the ANSYS stress analyzer program. It lists the spline coupling model 20’s geometric configurations and specification values for each feature. The spline coupling model 20 is automatically recreated every time the configuration or performance specifications of the spline coupling model 20 are modified.
The spline coupling model 20 can be configured using the product model software program 10. A user specifies the axial length of the spline stack, which may be zero, or a fixed length. The user also enters a radial mating face 148, if any, and selects a pilot clearance specification value of 14.5 degrees or 30 degrees.
A user can then use the mouse 110 to modify the spline coupling model 20. The spline coupling knowledge base contains a large number of possible specification values and the spline coupling design rule. If the user tries to change a spline coupling model, the model will show a warning about a violation of another specification. In some cases, the modification may invalidate the design.
In the spline coupling model 20, the user enters additional performance requirement specifications. The user chooses the locations where maximum torque is transferred for the internal and external splines 38 and 40. The maximum torque transfer location is determined by the attachment configuration of the hardware to the shafts. Once this is selected, the user can click “Next” to save the model. A preview of the spline coupling model 20 is displayed.
The model 20 is a representation of a spline coupling. The spline specifications are entered in the order and arrangement as specified on the spline coupling model 20 GUI screen. Once the spline coupling specifications are entered, the product model software program 10 will incorporate them into the spline coupling model 20. This is the last step in spline coupling model creation.
splineshaft

Analysing a spline coupling model 20

An analysis of a spline coupling model consists of inputting its configuration and performance specifications. These specifications may be generated from another computer program. The product model software program 10 then uses its internal knowledge base of configuration dependent specification relationships and constraints to create a valid three-dimensional parametric model 20. This model contains information describing the number and types of spline teeth 32, snaps 34, and shoulder 36.
When you are analysing a spline coupling, the software program 10 will include default values for various specifications. The spline coupling model 20 comprises an internal spline 38 and an external spline 40. Each of the splines includes its own set of parameters, such as its depth, width, length, and radii. The external spline 40 will also contain its own set of parameters, such as its orientation.
Upon selecting these parameters, the software program will perform various analyses on the spline coupling model 20. The software program 10 calculates the nominal and maximal tooth bearing stresses and fatigue life of a spline coupling. It will also determine the difference in torsional windup between an internal and an external spline. The output file from the analysis will be a report file containing model configuration and specification data. The output file may also be used by other computer programs for further analysis.
Once these parameters are set, the user enters the design criteria for the spline coupling model 20. In this step, the user specifies the locations of maximum torque transfer for both the external and internal spline 38. The maximum torque transfer location depends on the configuration of the hardware attached to the shafts. The user may enter up to 4 different performance requirement specifications for each spline.
The results of the analysis show that there are 2 phases of spline coupling. The first phase shows a large increase in stress and vibration. The second phase shows a decline in both stress and vibration levels. The third stage shows a constant meshing force between 300N and 320N. This behavior continues for a longer period of time, until the final stage engages with the surface.

Misalignment of a spline coupling

A study aimed to investigate the position of the resultant contact force in a spline coupling engaging teeth under a steady torque and rotating misalignment. The study used numerical methods based on Finite Element Method (FEM) models. It produced numerical results for nominal conditions and parallel offset misalignment. The study considered 2 levels of misalignment – 0.02 mm and 0.08 mm – with different loading levels.
The results showed that the misalignment between the splines and rotors causes a change in the meshing force of the spline-rotor coupling system. Its dynamics is governed by the meshing force of splines. The meshing force of a misaligned spline coupling is related to the rotor-spline coupling system parameters, the transmitting torque, and the dynamic vibration displacement.
Despite the lack of precise measurements, the misalignment of splines is a common problem. This problem is compounded by the fact that splines usually feature backlash. This backlash is the result of the misaligned spline. The authors analyzed several splines, varying pitch diameters, and length/diameter ratios.
A spline coupling is a two-dimensional mechanical system, which has positive backlash. The spline coupling is comprised of a hub and shaft, and has tip-to-root clearances that are larger than the backlash. A form-clearance is sufficient to prevent tip-to-root fillet contact. The torque on the splines is transmitted via friction.
When a spline coupling is misaligned, a torque-biased thrust force is generated. In such a situation, the force can exceed the torque, causing the component to lose its alignment. The two-way transmission of torque and thrust is modeled analytically in the present study. The analytical approach provides solutions that can be integrated into the design process. So, the next time you are faced with a misaligned spline coupling problem, make sure to use an analytical approach!
In this study, the spline coupling is analyzed under nominal conditions without a parallel offset misalignment. The stiffness values obtained are the percentage difference between the nominal pitch diameter and load application diameter. Moreover, the maximum percentage difference in the measured pitch diameter is 1.60% under a torque of 5000 N*m. The other parameter, the pitch angle, is taken into consideration in the calculation.
