THE DAMAGE OF THE RACES OF LARGE BEARINGS
Journal Title: Tribologia - Year 2011, Vol 237, Issue 3
Abstract
In this paper, some form of large bearing race damages and their causes are presented. Particular attention was paid to the single row four-point contact ball bearing races. The variations of the contact angle of the ball bearing are analysed, taking into consideration susceptibility to bending and twisting of bearing races. Simulation research was carried out using the finite element method. The identification of the contact angle of each individual ball was obtained. Limited load from axial force and overturning moment was considered. The results indicate that the contact angle of some rolling elements augment significantly. It may cause the ruin of the race through the rolling of bearing ring edges. Ways are proposed to avoid premature race damages through design and bearing selection.<br/><br/>
