滚动轴承

The residual stress formed on the surface of rolling bearing in superfinish hard turning will influence the fatigue life of rolling contacting after stress decay.

超精硬态切削在轴承表面形成的残余压应,作应衰减后才成为影响接触疲劳寿命的应状态。

In order to prevent the reduction of the working accuracy of S1-280 Type Lathe that is made from overwear of main shaft bush bearing, it is substituted with rolling bearing.

车床主轴支撑滑轴承轴瓦严重磨损,加精度降低,故改轴承支撑。
