Constant velocity joint

A constant velocity joint, comprising:

• an inner race having opposite inner race sides with a plurality of inner rolling member tracks following an inner rolling member track helical path relative to the central axis of rotation, each inner rolling member track having an inner rolling member track radius of curvature extending from one of the inner race sides to the other of the inner race sides;
• an outer race disposed about the inner race such that the inner race and the outer race extend about a common central axis of rotation, the outer race having opposite outer race sides with a plurality of outer rolling member tracks following an outer rolling member track helical path relative to the central axis of rotation, each outer rolling member track having an outer rolling member track radius of curvature extending from one of the outer race sides to the other of the outer race sides, the outer rolling member tracks being arranged in paired relation with the inner rolling member tracks to define a plurality of rolling member raceways;
• and
• at least one rolling member disposed in each of the rolling member raceways for rolling receipt in the inner rolling member tracks and the outer rolling member tracks,
• wherein at least one inner rolling member track radius of curvature has a convex radius of curvature and the paired outer rolling member track radius of curvature has a concave radius of curvature,
• wherein at least one inner rolling member track radius of curvature has a concave radius of curvature and the paired outer rolling member track radius of curvature has a convex radius of curvature.
