Abstract: A constant velocity universal joint has an outer race provided with longitudinally extending, circumferentially spaced outer race grooves in its inner concave surface. An inner race is provided with longitudinally extending, circumferentially spaced inner race grooves 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 is disposed in each of the crossing ball-groove pairs for movement therealong during the relative angular movement of the inner and outer races.

Abstract: A constant velocity joint comprises an outer race, an inner race, a plurality of balls and a cage. The outer race and inner race have crossed grooves of multiform length. The outer race grooves and the inner race grooves are circumfercntially spaced and paired to hold the balls. The central planes of paired grooves are inclined from the longitudinal direction and are crossed relative to one another. The outer race, inner race and cage having mating part-spherical surfaces that accommodate joint angulation while supporting the components against axial stroking about a fixed center. The grooves have a substantially uniform depth along their lengths including toward the closed end of the outer race to provide full support to the balls at high joint angles.
