Abstract
A rotatable combination that includes first and second members respectively having first and second longitudinally extending pluralities of splines. The second plurality of splines extend substantially parallel to the rotational axis. The first plurality of splines includes first and second longitudinally extending sections having different orientations with the second longitudinal section defining an angle with the rotational axis. The first longitudinal section engages the second plurality of splines before the second longitudinal section during assembly of the two members. Engagement of the second longitudinal section with the second plurality of splines generates a greater resistance to longitudinal movement than engagement of the first longitudinal section with the second plurality of splines. Engagement of the second longitudinal section with the second plurality of splines rotationally couples the first and second members in a backlash-free engagement and may be advantageously employed with a constant velocity joint.
