摘要：
A model for kinematic analysis of the high speed angular contact ball bearing are constructed. The friction moment model of ball bearing are given. Heat generation of the high speed ball bearing is studied by analyzing the local friction in the bearing. A new model for evaluating bearing temperature is set up treating the contact surfaces between rolling elements and raceways as moving heat sources. Using this model and finite element method, friction power loss and operating temperature of the high-speed angular contact ball bearing in high speed electric spindle system is studied. It can be found that the maximum heat generation and temperature rise of the ball bearing located the inner raceway where the surface damage occurs easily.
