Abstract

Determining the parameters of angular contact ball bearings under preload is the key issue to improve the accuracy and performance of high-speed spindle. The impact of gyro force and centrifugal force were considered, a static and a dynamic model for angular contact ball bearings under rigid preload were presented. By using Newton iterative method, dynamic parameters of the angular contact bearings were obtained, including eccentricity of contact ellipse, contact angle, contact force, maximum contact stress, contact ellipse radii and stiffness, etc. According to numerical simulation, relationship between the parameters, versus preload and versus rotation speed were given. The results reveal that the stiffness increases as the preload increases appropriately, the contact stress and contact ellipse radii increase as the preload increases excessively. In addition, under rigid preload this model has no bearing softening effect. This method provides valuable theoretical basis for further researches, such as calculating bearings calorific value, calculating bearings fatigue life and optimizing bearings structure, etc.
