Abstract

The analysis and computation on stress and load-distribution state of rolling bearings via finite element method is one of the major studies on rolling bearings. This finite element analysis is much more complicated than that of common structures because of the contact problems existed in it and most of them can not be treated as plane prolems. This paper not only discusses the basic method of 3D contact finite element analysis and its solving technique in terms of the characteristics of four-row taper roller bearings attached to cold-rolling-mill work rolls, but also presents a simplified analytical model and computing results. The load-distribution curve under different working conditions is illustrated too in this paper.
