ABSTRACT OF THE DISCLOSURE A double Cardan universal joint is provided with improved centering means. One end joke of the joint has a plurality of cir- cular ridges or gear teeth facing the other end yoke with the center line of the gear teeth being coaxial with the axis of rotation of the one yoke. The other end yoke has a plurality of circular ridges or gear teeth facing the one end yoke with the center line of those gear teeth coaxial with the axis of rotation of that yoke. The teeth are positioned so that one tooth extends between two teeth of the other yoke for any position of the end yokes and the drive and driven mem- bers or shafts to which they are attached. One of the end yokes has a gear-tooth shaped projection at the center line and the other has a gear-tooth shaped recess at its center line. The sets of teeth are in patterns of sphere segments so that any longitudinal cross section taken centrally through the gear teeth has the same appear- ance as a spur gear segment. The tooth profile is such that points of contact are always on the pitch radii at the intersection with a line through the center of the sphere segments of the gear teeth.
