Abstract

In order to improve the service life of bearing rings, a new method of cold rolling bimetal composite bearing rings was proposed in this paper.With Abaqus software,a finite element simulation model of the cold rolling of bimetal composite bearing rings was established. The law of the radial stress distribution, the diameter growth and the deformation of plastic zone during the cold rolling of bimetal composite bearing rings were analyzed. The results of these analyzes are helpful to study the deformation characteristics of the cold rolling of bimetal composite bearing rings. The results show that the bimetal composite bearing ring interface is well bonded and no segregation occurs during the process of cold rolling.
