外球面轴承座的内球面车削工艺

Turning technology for the spherical bore of Spherical outside surface bearing housing

在分析外球面轴承座的内球面几种车削方法的基础上,制定了合理的车削工艺,即在同一台专用车床上,一次定位夹紧工件,采用三把刀分别完成粗车内球面、切沟槽和精车内球面。重点分析了内球面的范成车削法,介绍了专用车床的主要结构特点。

The reasonable turning technology is worked out on the basis of analyzing several turning methods for the spherical bore of spherical outside surface bearing housing, that is the three tools are installed in a special lathe, for rough turning spherical bore groove and precision tourning bore respectively, the spherical bore turning by generating method is analyzed in detail and the main construction characteristics of the special lathe are introduced.
