Shaft Collar

How to Choose the Right Shaft Collar

A shaft collar is a small, inexpensive machine component that serves a variety of purposes in power transmission. It is most commonly used in gearboxes and motors. It can serve as a mechanical stop, bearing face, or locating component. Its simple design makes it easy to install. Here are some of the most common types and their functions.


Shaft collars are an important part of many mechanical systems. These devices hold mechanical components on a shaft and also help mount shafts on flat surfaces. They are available in many different styles, sizes, and materials. Selecting the right shaft collar is essential in preventing damage to components. Stafford Manufacturing, a leading manufacturer of shaft collars and other related mechanical components, can help you choose the right one for your application.
There are two main types of shaft collars. The first is the Heavy Duty type. It has a larger outer diameter and wider opening. While this may seem to increase holding power, the problem with that is that it can reduce the amount of space the collar has on the shaft. On the other hand, the Thin Line type is similar, but is made with smaller outer diameters. Another type is the Threaded Bore shaft collar. These shaft collars offer exceptional axial holding power, and are designed to protect threaded shafts without causing any damage.
A shaft collar has many uses and is typically used in industrial applications. It can act as a spacer and to stop shaft movement in reciprocating applications. It can also be used to align and position parts of automation machinery.


There are several different types of shaft collars. These components are critical for a variety of applications, and their design plays a large role in the performance of the resulting product. To select the most appropriate collar, designers must consider several factors, including the style, material, bore size, and geometry of the shaft. Many manufacturers provide performance data, and users can contact them for assistance.
There are many different types of shaft collars, which make it important to understand how each one works and what applications they can serve. Fortunately, shaft collars are easy to install and require little maintenance. Whether you need to secure industrial railings or position medical equipment, shaft collars are a versatile component that can be tailored to meet your needs.
One type of shaft collar is the locking collar. This type of shaft collar has a threaded end that is designed to mate with spindle bearings. They offer an increased TIR than standard shaft collars and allow for precise preload control. They also feature slots for spanner wrenches.
Shaft Collar


Shaft collars come in a variety of sizes. You can get a small diameter shaft collar for small equipment, or a large diameter shaft collar for larger equipment. Both styles are made from solid steel, and they come in several thicknesses. You can choose between one-half inch and six-inch collars, depending on your needs.
There are no specific standards for shaft collars, but most manufacturers have similar designs. They’re either single-point faced or double-split, and can be fine or coarse threaded. They’re often used as mechanical stops, bearing faces, or as locating components. Their bore is either fine or coarse, and their outside diameter and width are determined by the shaft diameter.
Shaft collars are commonly found in mechanical and automation equipment. These ring-shaped devices hold motor components, sprockets, and bearings in place. They also allow them to be adjusted and positioned precisely. A shaft collar is often used to connect the end of a shaft to a mechanical stop.
Another type of shaft collar is called a set collar. It has a recessed area for a screw to bite into a shaft. These collars are perfect for holding sprocket hubs, bearings, and spacers. They can also be used as a rigid coupling.


When choosing a shaft collar, consider its intended application and cost. Some shaft collars are very expensive while others are quite affordable. Choose one that meets the needs of your assembly. If you’re using the shaft collar infrequently, a clamp style or a set screw style may be a better choice. Then, you can easily adjust or disassemble it with just a few tools. If you’re using it more frequently, choose a two-piece shaft collar.
The material of the shaft collar is also an important consideration. Steel and stainless steel are common choices. While both materials are strong and durable, steel tends to have better holding power. However, aluminum shaft collars are lighter and provide better strength-to-weight ratio. The type of material you choose depends on the amount of corrosion protection you need, and whether you’ll need the collar to resist extreme temperatures. If the shaft collar is going to be used in a hot environment, you may want to go with a titanium collar.
There are many different sizes and types of shaft collars. The type of collar you choose depends on the specific application and the system it’ll be used in. Consider the dimensions of your shaft, the material of the shaft, and the length of the shaft to find the right fit. If you’re not sure what size you need, ask a manufacturer for help.
Shaft Collar

Placement on shaft

In some applications, the placement of the shaft collar can be critical to the overall performance of the machine. The collar’s design must take many factors into account, including material, style, bore size, and shaft geometry. If a user is uncertain of the proper placement of their collar, they should refer to the manufacturer’s website for guidance.
While shaft collars may look simple, they’re actually essential mechanical components that are used in almost every type of machinery. Despite their ubiquitous use in every industry, they are often underappreciated due to their complexity. Many people aren’t aware of their importance or the various types of collars available. This shaft collar guide will provide detailed information to help you find the right shaft collar for your specific application.
The surface treatment of the shaft collar is another important factor that contributes to its holding power. The most common treatment is a black oxide finish. This finish enhances screw torque while preserving the frictional properties of the bore. This finish can be further optimized by applying light oil to the screw. Zinc plating is also a good option for shaft collars. This material offers better corrosion resistance, but can reduce holding power.

Clamp style

A clamp style shaft collar is a simple and effective tool for securing shafts in machine tools. Its two-piece design allows for quick and easy positioning adjustments and has greater holding power than set screw collars. In addition, its friction-based connection maintains ease of use and prevents shaft damage. This type of collar is also more corrosion resistant than set screw collars.
There are several different types of shaft collars, including single and double split collars. Single-piece clamp collars are anchored into the shaft with a single tangential screw, whereas double-piece collars are anchored to the shaft with two socket cap screws. The latter type provides more stability and axial holding power and is suitable for rotating assemblies. A single or double-piece clamp collar can also be threaded to allow for precise positioning along the shaft. Its internal threads also provide enhanced support for high axial loads and act as a positive mechanical stop.
There are different types of shaft collars, each with its own set of advantages and disadvantages. A set-screw collar may be preferred over a clamp-style shaft collar, but it’s not the only choice. A set-screw collar can severely mar the shaft and can prevent fine adjustments. However, it is a good idea to use the torque wrench when tightening a shaft collar.

Zinc plated

Zinc plated shaft collars are available in a variety of sizes. They are precision machined from cold finished steel bar stock and zinc plated for corrosion resistance. They are also very attractive. They are made in the USA. Whether you need a zinc-plated shaft collar for a simple repair or a more complicated installation, Lovejoy has the right solution for your needs.
The CZPT MSP-12-FZ two-piece shaft collar has a 12mm bore, 28mm OD, and 11mm width. Its clamp style design allows you to easily install and remove the shaft collar. It is easily adjustable and is stamped with the CZPT name.

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 one 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 two shafts, one 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 two 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 one 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 four 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.
