ABSTRACT:
A modified jaw type shaft coupling has two opposed members arranged to allow limited flexure about a point that is the geometric center of mating spherical surfaces, a concave surface on one member and a mating convex surface on the other member. One member is attached to each shaft to be rotationally and axially coupled. The jaws on one coupling member have lugs that extend radially inward to axially entrap a larger flange attached to the other coupling member. The flange has notches to allow the flange to axially traverse the lugs. The flange is then rotated relative to the lugs to allow the flange to oppose the lugs. The flange is secured to the other coupling member after the coupling members are axially moved together to allow the jaws to interdigitate to provide rotational coupling. The convex and concave surfaces cooperate to accept axial compressive loads and the flange and lugs prevent axial separation.
