Abstract:
A shaft coupling comprising:first and second hubs, each having respective first and second faces;first and second pluralities of teeth extending from the respective first and second faces, the teeth on the first face in parallel alignments with the teeth on the second face, the aligned teeth forming gaps between adjacent pairs of aligned teeth;a split, flexible belt having opposed edges and an inside and an outside surface, a plurality of spaced projections on the inside surface, each of the projections occupying one of the gaps,a first groove on the outside surface of the belt extending substantially perpendicular from one edge of the belt,a second groove on the outside surface of the belt in communication with the first groove and extending substantially perpendicular from the first groove and positioned between a mid-point of the belt and one of the edges, the second grove terminating at an end cavity,a third groove on the outside surface of the belt in communication with the first groove, and extending substantially perpendicular to the first groove, but in an opposite circumferential direction than the second groove and positioned between the mid-point and the other of the edges of the belt, the third groove terminating in an end cavity and adapted to receive the locating pin,an endless retainer band adapted for mounting around the belt, the band having interior and exterior surfaces, and opposed band edges,a locating pin protruding from the interior surface of the band, the locating pin received in the first groove as the retainer band is slid over the belt and received in the end cavity of the second or third grooves to restrain the band from farther circumferential rotation with respect to the belt regardless of the direction of rotation of the shafts.
