Flexible wrap-type shaft coupling

摘要

A flexible coupling assembly adapted for mounting on the ends of a shaft in coaxial alignment. The coupling includes a pair of annular hubs. A plurality of radially outwardly opening receptacles are spaced around the circumferential edge of each hub. A molded flexible belt is wrapped around the circumferential edge of both hubs, and has a plurality of spaced resilient teeth extending from one side of the belt. Each tooth is received in a pair of aligned receptacles formed in the hubs. The belt is molded with a length greater than the circumference of the circumferential edge, and the belt is cut to a length such that there is no more than one tooth per pair of receptacles. An annular retainer is slipped over the belt to retain the teeth in the receptacles. The retainer is held over the belt by at least one deformable pin extending from another side of the belt, and the pin is received in a circumferential groove formed on an inner surface of the annular retainer to retain the retainer over the belt.
