Bearing cage for constant velocity cross groove drive joint has profiled thrust faces to minimise damage risk between cage apertures and bearings

摘要

A bearing cage design for a constant velocity cross groove drive joint has each thrust face (26) with a greater curvature than the ball bearing for accurate location of the bearing and to minimise the contact drag between the bearing and the cage. The opposite thrust face is either plane or convex for a positive location of the ball bearing. The bearing races can have straight or spiral sections w.r.t. the drive shaft axis.
