Quasi-Static Analysis on a Large-Sized Four Contact-Point Slewing Bearing with Negative Axial Play

Abstract:

A quasi-static analysis of a large-sized four contact-point slewing bearing with negative axial play is performed. The values of normal contact loads of a slewing ring bearing between balls and inner/outer ring were computed at different negative axial plays without applied load. The results show that the normal loads of the four contact points increase as the absolute value of negative axial play increases. Slightly changing negative axial play makes big change on normal contact load. Startup friction torque can be improved largely by increasing slightly the absolute value of negative axial play.
