How Does Freewheel Clutch Bearing Works?

There are different types of bearing specially designed in order to fulfill the needs of their users in all ways. The Freewheel clutch Bearing is considered the best machine element essential to permit the rotation in one direction. It is an excellent brace to transfer the torque in the opposite directions. The force transfer can be taken place from the driving side. The torque can be applied at the outer as well as inner rings as in the desired form. The Sprag slide on the rotating raceway surface of the rings is in sliding frictions in the time of rotary motions in the idle directions. The torques is not transferred to the driven side.

How Does Sprag Clutch Bearing Work?

The Sprag Clutch Bearing looks like a roller bearing. It is essential to allow the necessary elements to roll in freely. They lock when it is rolled in the opposite directions. It has three main stopping options, they are

• Indexing

• Backstopping

• Overrunning

The Sprag clutch is the cam-shaped steel wedges that are placed at an angle, and it is controlled in one way direction of the movements. The movement tries to go in the opposite direction by the instant driving disengagement as well as locking may occur. The wedging actions of the Sprag are essential to allow the torque which is passed from one raceway to others. It is designed for max torque capacity, and there are different numbers of Sprag in all clutches that depend on the torque of the clutch.

About Overrunning Clutches:

The Overrunning clutch Bearing is otherwise called freewheel clutches. It is used to freewheel in one direction by driving in another direction of the rotation. The driven shaft is in rotating faster while comparing to the drive shaft. The clutch is mechanically disconnected to the drive shaft from the driven shaft. It is widely used in heavy-duty applications like agriculture, mining, industrial metal processing, indexing, and aerospace. It is also used in multiple speed, backstops, dual and one-way drives. There are four types of running clutches: wrap spring, wedge style, Sprag, and roller ramp. The longest-lasting design in the roller ramp clutch has many special features that the cylindrical roller that is positioned in wedge-shaped areas, which is formed in the outer cylindrical surface and an inner flat surface.
