调心滚子轴承内圈滚道仿形车削的质量控制

Quality control of contour turning of self-aligning roller bearing inner ring raceway

为保证内圈滚道在仿形车削时其形状和位置的加工质量,滚道车削前通常要进行平面软磨或精车。在仿形车床上利用仿形板车削滚通后,要对用R样板和滚道位置样板检查两个圆弧滚道的形状和位置,用D724等相应仪器检查和控制两滚道的尺寸精度。

In order to ensure the manufacturing quality of the shape and location of the inner ring raceway during contour turning,the surface of the raceway needs to be softly grinded and finish turning.After using the gauge finder to turning the raceway on the contour lathe,the shape and location of the raceway should be checked by R type template and raceway location template,and D427 should be used to exam and control the dimension precision of the two raceway.
