高速小型复合分子泵中的轴承为混合陶瓷球轴承，轴承在工作过程中由于摩擦力矩会产生大量的热量，影响分子泵的正常工作。采用Palmgren发热量计算模型给出了具体工况下陶瓷球轴承生热量的计算公式，应用有限元分析软件ANSYS Workbench得到了轴承的温度场分布，为陶瓷球轴承的润滑和延寿奠定基础。

Bearing of high speed small composite molecular pump is hybrid ceramic ball bearings. The friction torque of bearing generated a lot of heat,affecting the normal work of the composite molecular pump. Based on the special working conditions,the ceramic ball bearing heating was calculated. This pa-per applied the finite element method to get the temperature field distribution of the bearing. It laid the foundation for the ceramic ball bearing lubrication and Life extension.
