英文摘要	Based on the elastic theory, dynamics and raceway control theory of the rolling bearing, inner ring radial displacement of angular contact ball bearing caused by centrifugal force was calculated. In consideration of inner ring radial displacement, interference fit and preload, the comprehensive method and its corresponding program were given for calculating the contact angular of angular contact ball bearing during high-speed rotating. The calculated results taking 7012/CD bearing as an example show that because of inner ring centrifugal displacement, inner contact angular tend to decrease and the decrease of outer contact angular tend to slow with the increase of rotation speed when its rotation speed exceed a certain number; axial preload can restraint the variation of contact angular with the rotation speed; the interference fit has no effect on this variation of contact angular.
