Abstract
A constant velocity joint has an outer race, inner race, and balls interposed therebetween. The balls are seated in apertures of a cage. The inner wall profile of the cage has a cross section contour through the longitudinal axis that is radial about a radius that has its center origins offset from the center point of the cage along the ball center plane. The outer wall profile also has a cross sectional contour that is radial about a radius with its center also offset from the center point along the ball center plane of the cage and from the radial center of the inner wall radius.
Claims6
A constant velocity joint, comprising:
- an inner race;
- an outer race;
- a cage disposed between said inner race and said outer race;
- a plurality of torque-transmitting balls disposed between said inner race and said outer race and captured by said cage;
- and
- wherein said cage has an outer wall surface of predetermined convex curvature in an axial direction of said cage, and an inner wall surface of predetermined concave curvature in said axial direction, said outer and inner wall surfaces being non-concentrically arranged along a central longitudinal axis of said cage to provide a variable wall thickness to said cage that is greater adjacent a ball center plane of said cage and tapers to a lesser thickness adjacent opposite axial ends of said cage.
