What Is The Function Of Collar In Mechanical?

collars serve as important mechanical functions in transmission applications. They act as mechanical stops, locating components and load-bearing surfaces. As with many mechanical components, there are various types available. They are used in many industries including auto, medical, packaging, food and beverage, and many others.

Set Screws

Standard set screw collars, the most commonly used type of shaft collars, are used as locating and retaining components. The set screw locks down the collar by digging into the shaft to hold the collar’s position. Therefore, they are most ideal when applied to a shaft made of a material softer than the screw. Set screw collars produce higher holding strength and torque capacity than other methods. They are typically used to lock power transmission components in place, such as gears, sprockets, pulleys, and bearings.

Clamping Shaft Collars

Clamping shaft collars were designed to overcome the issues that set screws present. Rather than damaging the shaft, they are mounted using compression and clamp down to lock into place. There are two styles available, one-piece and two-piece.

One-piece – provides even distribution with only one screw. This allows it to be repositioned as required. However, since it’s placed over the end of the shaft, it must be placed when the assembly is apart.

Two-piece – contains two screws and therefore holds a lot tighter than a one piece. If you remove both screws, you can it place over the shaft and assemble in place without moving other components. The assembly does not need to be pulled apart, saving time, effort and money.
