轴承内圈挡边中，双列调心滚子轴承中挡边和圆锥滚子轴承大挡边为球面挡边 (图 1)。球面挡边中心和内滚道母线交点重合。对于中小型轴承可采用 M8812T等挡边磨床磨削球面挡边，但对于没有挡边磨床的中小型轴承球面挡边和大型轴承的球面挡边就需另想办法。 先来分析用 M8812T磨
Bearing inner ring ribs, double row spherical roller bearings in the ribs and tapered roller bearings large ribs for the spherical ribs (Figure 1). The intersection of spherical surface center and inner raceway bus coincide. For small and medium-sized bearings can be used M8812T and other edge grinding grinder spherical ribs, but there is no grinder for small and medium-sized bearings spherical ribs and large bearings spherical ribs need to find a solution. First to analyze with M8812T mill
