氮化硅陶瓷滚子轴承的加速寿命试验和断油润滑试验

本文介绍了一次组合陶瓷轴承的加速寿命试验和断油润滑试验，试验轴承是用于某航空发动机主轴前支承的短圆柱滚子轴承，滚动体由氮化硅陶瓷材料制成，套圈和保持架仍采用原钢轴承的套和保持架，试验设备为航空轴承专用试验台，试验表明，试验陶瓷轴承在高速条件下工作寿命和短期油润滑能力均好于同型号钢轴承。

Accelarating Life test and Shut - off Oil Lubrication of Hybrid Bearing

This paper presents an accelerating life test and shut - off oil lubrication of hybrid ceramic bearing. The bearings are used as a main shaft bearing of an aircraft turbine engine. Its rollers are made of silicon nitride ceramic materials, and its races and cage are ordinary races of steel bearings. The test rig is a specific testing device of aircraft engine bearing, The test result shows that the working life and the ability of shut - off oil of ceramic bearings are more superior than of the same type steel bearings.
