Abstract
The design of Clutch Release Bearings (CRB) is usually based on angular contact ball bearings. This kind of bearings supports both axial and radial loads and the load limits depend directly on the contact angle. The CRB has its own particularity, since it is a radial angular contact ball bearing and its main load is on axial direction. Due to this special situation, this work is done to evaluate this CRB design according to the classical theory of bearing life calculation, developed by Lundberg and Palmgren (1947), which the standard ISO 281 is based on. The analysis is focused on the basic dynamic load rating of the bearing, which briefly means the expected load that the bearings support a life of 1 million cycles. This expectation follows a Weibull distribution with increasing failure ratio and a specific reliability.
