N2 - According to the elastic theory the calculating formulas of inner ring centrifugal displacement are inferred, in consideration of inner ring centrifugal displacement the basic equations of angular contact ball bearing are set up, effect of inner ring centrifugal displacement on the dynamic characteristics of high-speed angular contact ball bearings are studied. The results from taking 7012C bearing as an example show that, in high-speed condition inner ring centrifugal displacement decreases ball centrifugal force and increases ball gyroscopic moment, reduces the difference between inner and outer contact angles, increases contact deformation and contact stress, decrease spin-roll ratio between ball and inner raceway. Furthermore, the inner ring centrifugal displacement not only compensates angular contact ball bearing axial and angular stiffness softening due to centrifugal force but also greatly increases its radial, axial and angular stiffness. Therefore, in order to make the dynamics analysis of angular contact ball bearing more accurate and closer to the factual condition, the effect of inner ring centrifugal displacement should be considered.
