摘要
用金相、透射电镜及光谱分析的方法,对国内外航空发动机主轴轴承保持架材料进行了研究。结果表明,国外保持架材料的质量优于我国。在高温、高速和重负荷条件下应选用钢制保持架。
The material of spindle bearing cage of aircraft engine at home and abroad has been studied by means of OEM,TEM and spectral analysis. The results shows that the material quality of foreign cages are better than that of our country. The spindle bearing cage made from steel should be selected under the condition of high temperature, high velocity and heavy load.
