Brief description of one-way clutch

One-way clutches (bearings) are those that can drive in one direction but overrun in the other. However, in service different models will contain different load characteristics and require changes in the structural technical details of the clutch.

Therefore, one-way clutches are divided into three categories for the functions they were originally intended to use, namely overrunning, indexing and backstop.

1. Overrun one-way clutch bearing

This type of clutch can be used in a variety of ways, mainly as a speed conversion of various mechanical devices.

2. Indexing one-way clutch bearing

In this form of application, the reciprocating motion provided to the drive race is converted into intermittent motion on the driven race and in only one direction.

3. Reverse one-way clutch

In back-stop applications, a raceway is often mounted on a device that is fixed relative to the ground. The function of a one-way clutch is a mechanical device that allows connection to other races, in one direction only, and prevents any rotation in the opposite direction at any time. Although this type of one-way clutch overruns most of the time, it provides backstop for things like conveyor belts, gear reductions, and the like, because its function is to prevent reverse rotation.
