摘　　要：针对高速固体润滑轴承的高频剪切作用引起的摩擦发热,温度升高以及磨损物增多、堆积等问题,对影响轴承摩擦发热的自旋速度、滑滚比等性能参数进行分析,以接触应力和滑滚比为目标函数优化719/7轴承结构主参数,优化后轴承在真空、转速为4 000 r/min工况条件下寿命达到4×10~8 r。In view of the problems of friction heating, temperature rise, increase and accumulation of wear debris caused by high-frequency shear action of high speed solid-lubricated bearings, the performance parameters are analyzed such as spinning speed and slip roll ratio that affect the friction heating of the bearings. Taking contact stress and slip roll ratio as objective functions, the main structural parameters of 719/7 bearings are optimized. After optimization, the service life of the bearings reaches 4×10~8 r under the conditions of vacuum and rotational speed of 4 000 r/min.
