A quick release clutch coupling for coupling two flanges between which torque is transmitted. Each flange carries a pair of axially extending clutch elements, each of which has bearing surfaces so that the clutch elements of opposite facing flanges engage each other along the bearing surfaces for the transmission of torque from one flange to the other. The engaged bearing surfaces of each clutch element lie in a plane which passes through the axis of rotation of the coupling. A bolt, which has oppositely pitched threads, is mounted for rotational movement by a guide on the coupling, and the axis of rotation of the bolt extends in a direction transverse to the axis of the coupling. A pair of tension shoes are carried on the bolt for displacement in opposite radial directions upon rotation of the bolt for preventing axial displacement of one coupling flange with respect to the other. Each clutch element has a further bearing face which bears against one of the tension shoes. The tension shoes are configured such that the distance between these bearing faces and the longitudinal axis of the bolt decreases in a direction extending radially away from the center of the coupling. |
