ABSTRACT:
A dynamic tooth clutch interposed between two rotating members for coupling same includes a first collar slidably mounted on one of the members and has a plurality of equally angularly spaced axially extending radial first inner and outer teeth. A second collar is fixed to the other member and has a plurality of equally angularly spaced axially extending radial second outer teeth that are designed to intermesh with the first outer teeth and are so angularly spaced that when the first and second outer teeth are centered relative to one another there can be a first predetermined amount of bidirectional angular rotational movement therebetween before there is abutment of adjacent tooth side surfaces. A cam ring coacts with the second collar, with the cam ring being capable of a predetermined amount of bidirectional angular rotational movement relative to the second collar. The cam ring, which is preloaded and self-centered relative to the second collar, has a plurality of second inner teeth that are angularly aligned with the second outer teeth in the self-centered cam position, with the combined tooth depth of the first and second inner teeth being greater than the combined tooth depth of the first and second outer teeth, thus permitting axial end abutment of only the inner teeth in the absence of intermeshing. The force for displacing the first collar toward the second collar is less than the centering force on the cam ring thus permitting direct meshing of the first and second inner teeth but only complete centered axial meshing of the first and second outer teeth prior to the angular displacement of the cam ring relative to the second collar, thereby allowing full axial intermeshing of the first and second outer teeth before there is abutment and subsequent torque transfer between the outer teeth.
