What does a one-way clutch bearing do?
One Way Bearings are designed to transmit torque between the shaft and housing in one direction and allow free motion in the opposite direction. Proper mounting is easily accomplished with a simple press fit in the housing. Clutches and clutch and bearing assemblies are offered both in inch and metric series.
What type of clutch automatically engages in one direction but freewheels in the opposite direction?
Overrunning clutches, sometimes called freewheel clutches, are used to freewheel in one direction while driving in another direction of rotation. When the driven shaft is rotating faster than the driveshaft, the clutch mechanically disconnects the driveshaft from the driven shaft.
What is a sprag clutch used for?
A sprag clutch allows movement in one direction only and instantly prevents force from being driven in the opposite direction. It’s also called a one-way bearing or a freewheel clutch.
What are the three types of overrunning clutches?
Most overrunning clutches are one of three types: roller ramp, sprag, or wrap spring. A relatively new device, called the wedge ramp clutch, incorporates the major benefits of these well-established types.
Where are overrunning clutches used?
They are used in heavy-duty applications, such as agriculture, mining, aerospace, industrial metal processing, indexing, and more. They are often used when backstops, multiple-speed, dual- and one-way drives are required. Four types of overrunning clutches include the sprag, roller ramp, wrap spring, and wedge styles.
What is a freewheel sprocket?
A freewheel which is also known as a block, consists of either a single sprocket or a set of sprockets mounted on a body which will contain an internal ratcheting mechanism and mount on a threaded hub.
What is backstopping clutch?
Backstop clutches are used as a safety measure to prevent reverse movement of incline conveyors, bucket elevators, or pump systems. They not only help protect critical equipment from damage, they also help ensure worker safety.
