Dog Bone Coupling

A flexible, narrow-necked coupling connects a driven load to a motive source.

The coupling, constructed of plastic such as urethane, elastically secures together two shafts having diameters considerably larger than the coupling's central portion. The coupling may be assembled on the shafts by stretching its ends or by shrinking a tube onto the shafts. Air escapes during assembly through hole 1 or serrations 2 (which also increase the grip between the shafts and the coupling).

The source drives the load through the coupling smoothly even though the load position shifts from A to B. The coupling is a mechanical fuse if the materials are chosen to slip or fracture when a predetermined force is exceeded.
