摘要：Taking the off-sized balls and raceway error into account, the effects of axial preloading displacement on the mechanical performance of angular contact ball bearings are investigated in this paper. Through the geometric analysis of the angular contact ball bearing and the force balance, the contact load-deformation expressions of ball-to-raceway, the expression of load zone and their relation to axial preloading displacement are derived. By numerical calculation for a concrete example, we found the influences of preloading on the loading zone and maximum ball load and found the influences of off-sized balls and raceway error on the minimum preloading displacement, ball load distribution, inner ring centre trajectory and inner ring vibration frequency. Some curves about these influences are obtained and discussed.
