A shaft coupling system for accommodating axial displacement and angular misalignment between two shafts. A hollow bushing is force fit into the hollow end of a first shaft. The bushing is provided with a plurality of part-circular recesses on its inner surface. A spline adapter is slip-fit onto a second shaft. The spline adapter cooperates with the bushing, and has spline teeth extending from its outer surface which are substantially boat-shaped. The shape of the teeth allows for extra clearance at the ends of the coupling system, which is necessary to accommodate angular misalignment. The bushing is made of readily replaceable and relatively inexpensive plastic materials.

A shaft coupling system comprising: a first shaft having a hollow end; a hollow bushing secured within the hollow end of said first shaft; a second shaft having means for cooperating with said hollow bushing on the end of said second shaft, said means for cooperating having a surface arcuate in longitudinal cross section and having spline teeth extending from the surface, each of said spline teeth having an outer surface part-circular in longitudinal cross section, defined by a radius substantially greater than the distance between an axis of said second shaft and the outer surface of said teeth, and having a transverse cross section defined by substantially identical first and second part-circular arcs meeting at a single common point, said first and second arcs defining first and second sides respectively of the tooth, the radius centers of said first and second arcs coinciding at the point where the surface of said means for cooperating is the greatest radial distance from the center of said second shaft and from said point of coincidence to each end of said spline teeth, the radius center radius of said first arc is closer to said second side than to said first side, and the radius center of said second arc is closer to said first side than said second side, such that said teeth are tapered from said point to each end and the radial height of the teeth is greatest at the point of coincidence and decreases progressively from that point to each end.
