交叉滚柱式回转支承滚道剥落的原因一般是偏载造成的。而偏载的原因则主要是由于表面光洁度不高、滚道几何形状热处理变形和安装误差太大所造成。设计者对于受载前后,齿圈相对位置变化以及滚柱与滚道的45°°线接
Cross roller slewing ring raceway spalling is generally due to partial load caused. The partial load is mainly due to the surface finish is not high, heat distortion geometry and raceway installation error caused by too much. Designers before and after the load, the relative position of the ring gear changes and the roller and raceway 45 ° line connection
