Abstract

The paper deals with computational analysis of contact stress distribution of rolling elements of roller bearing with regards to the effect of slewing bearing ring at intervals from 0 to 8 and load rate variety at intervals from 25% to 100% of its basic static radial load capacity. The main goal is to present changes in contact ellipse and changes in contact stress for the logarithmic profile of rolling element. Analyzed effect is expressed by functional dependence which can be used in technical application.
