Abstract
The disclosure relates to a claw clutch mechanism, comprising opposing, interengaged clutch halves, each having axially projecting claws extending into the other. Cylindrical elastic bumpers are interposed between adjacent claws to absorb shock and accommodate axial displacement of the clutch halves. The clutch halves are of pressure cast aluminum construction, formed to provide large radius transitional fillets or roundings at the base of the claws, which correspond in radius to the contours of the cylindrical elastic bumpers. Integral reinforcing rings connect the angularly arrayed claws of each clutch half, both on the outside and the inside of the claws, to provide mechanical support for about half the length of the claw. The reinforcing rings also serve to confine the elastic bumpers, and may be provided with opposed flat surfaces at positions corresponding to bumper locations. The elastic bumpers, which advantageously are formed of a Polyamid plastic, may be connected by an integral bridge ring, accommodating limited torsional displacement of the individual bumper elements. Typically, all of the bumpers will be held in one clutch half, being retained therein by crescent shape spring levers carried by the claws of that clutch half.
