A constant velocity universal joint has an outer race (22,122) provided with longitudinally extending, circumferentially spaced outer race grooves (40, 140; 42,142) in its inner concave surface. An inner race (26,126) is provided with longitudinally extending, circumferentially spaced inner race grooves (44,144; 46,146) in its outer convex surface. The inner race is disposed within the outer race with its outer convex surface spherically engaged with the inner concave surface of the outer race for relative angular movement of the inner and outer races. Each of the inner race grooves is arranged opposite a corresponding one of the outer race grooves to define a plurality of ball-groove pairs. The grooves of each ball-groove pair are disposed in transverse crossing-relation to one another. A ball (52,152) is disposed in each of the crossing ball-groove pairs for movement therealong during the relative angular movement of the inner and outer races. <IMAGE> |
