Constant velocity drive joint has pairs of caged ball bearings with one ball of each pair supporting torque in one direction and vice versa for the second ball

摘要

A constant velocity drive joint with reduced drag has outer (102) and inner (104) bearing tracks with pairs of ball bearings (106) in cages. The tracks and cages are arranged so that one ball of each pair supports torque in one direction and one ball supports torque in the other direction. This ensures that half the balls and half the tracks transmit the torque.
