Needle roller, crowning (end relieving), centreless grinding machine


Needle roller bearings are designed to carry heavy radial loads but due to misalignment and edge loading it is affecting the life of the bearing. So in the design of needle roller bearings, the profile of the roller plays important role. Roller with crowning lead to reduce the edge stress concentration, so as to improve the service life of roller bearings. In this paper, the design of processing equipment for crowning rollers is developed and experimentation is performed, from which suitable radius of curvature of the wheels of modified centreless grinding machine is determined.
