Flexible couplings with end float limiting

A flexible coupling comprising:

• first and second hubs having a central axis and an annular cross-section, each terminating in respective first and second substantially flat annular surfaces;
• first and second pluralities of teeth integrally formed with and extending respectively from each of said first and second annular surfaces, the teeth being equally spaced around the circular periphery of each said annular surface, each tooth having an outer surface contoured to lie on the surface of a common cylinder, and a receptacle formed in each said outer surface;
• a split, flexible belt having a cylindrical outer surface and an inner periphery, said belt being removably wrapped about said first and second hubs and having a plurality of wedge-shaped projections formed around the inner periphery thereof, each wedge-shaped projection being separated from an adjacent wedge-shaped projection by an opening, each said opening receiving a tooth of said first plurality of teeth and a tooth of said second plurality of teeth, said belt being of a width such that the teeth of said first plurality do not contact the teeth of said second plurality;
• said belt further including first and second projection means in each said opening for releasably mating respectively with the receptacle of a tooth of said first plurality of teeth and the receptacle of a tooth of said second plurality of teeth for limiting motion of said first and second hubs substantially parallel to said central axis;
• and
• an endless metal retainer band mounted adjacent said belt.
