An assembly for joining together two splined shafts adapted to facilitate angular alignment of the splines relative to each other wherein one of the shafts is a splined hub having an opening formed in the wall thereof within which a ball is held with a given degree of play to enable rotation thereof, the center of the opening being in an axial plane with the center of one of the splines of the splined hub. The axial distance between the centerline of the opening and an end of the splined hub is identical to or greater than the axial length of a centering cylindrical surface formed between the splined hub end and the termination of the splines within the splined hub. The cylindrical centering surface engages the outer diameter of the splines of a splined shaft which is to be joined with the splined hub in order to ensure axial alignment between the shafts, with the ball engaging between splines of the splined shaft while being securely held in the opening so that the radial segment of the ball extending into the interior of the hub is equal to the gap between individual splines of the hub splined shaft. |
