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.

超硬态切削在滚动轴承表面形成的残余压应力,经作应力衰成为影响滚动接触疲劳寿命的应力状态。

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.

车床主轴支撑滑动轴承轴瓦严重磨损,加降低,故改用滚动轴承支撑。
