ABSTRACT:
A shaft coupling including a socket, a first shaft, a plug on a second shaft seated in the socket, and a clamp operative to clamp together the first and the second shafts in the direction of a longitudinal centerline of the shaft coupling to prevent dislodgment of the plug from the socket. The clamp includes an annular first flange on the first shaft, an annular second flange on the second shaft facing the first flange, oppositely facing frustoconical shoulders on the first and the second flanges, a plurality of clamp jaws pivotally mounted on the first shaft arrayed symmetrically around the first and the second flanges each having a closed position inducing radial thrust on the oppositely facing frustoconical shoulders, and springs biasing each of the clamp jaws toward its closed position. The oppositely facing frustoconical shoulders convert the radial thrust of the clamp jaws into linear thrust in the direction of the longitudinal centerline of the shaft coupling to force together the annular first and second flanges. A peripheral edge of the annular second flange pivots the clamp jaws to open positions against the bias of the springs to permit completion of the shaft coupling in quick-connect fashion.
