Abstract

Rolling element bearing components are subjected to high loads. These loads are transmitted from one bearing component to the next through Hertzian con- tacts. Since the bearing components are in motion as they transmit load, the elliptical contact region is subjected to normal as well as tangential pressure. The direction of the tangential pressure distribu- tion is dependant on the direction of the local slip vectors at each point within the elliptical contact. The purpose of the work presented here, is to study the influence of the local slip vectors in highly loaded elliptical Hertzian contacts. Instead of applying the conventional method of using a con- stant traction coefficient within the contact re- gion, the author, for the
