摘　　要：基于Hertz接触理论,分析并给出了高温、高速下定位预紧配对角接触球轴承的最小工作预紧力,以有效防止球的陀螺旋转,结合高温、高速工作中离心膨胀、工作温度及配合过盈量对轴承预紧力的影响,建立了初始预紧力及最小工作预紧力的关系,基于此关系编制计算软件,可以快速得到所需初始预紧力。The minimum operating preload is analyzed and given for fixed - position preload paired angular contact ball bearings used under high - speed and high - temperature based on Hertz contact theory, which is able to effectively pre- vent gyro rotation of balls. The relationship between initial preload and minimum operating preload is built with the in- fluences of high - temperature, centrifugal inflation in high speed operation, operating temperature and magnitude of in- terference fit on bearing preload. The calculation software is programmed based on this relationship, and the required initial preload is quickly received.
