ABSTRACT:
This gear unit connects coaxial drive and driven shafts. It comprises two integral coaxial externally-toothed cluster gears which mesh, respectively, with two coaxial internal gears, one of which is secured in the fixed housing of the unit and the other of which is fixed to one of the shafts. The other shaft has a crank secured to it which drives a pin that is coaxial with the cluster gears but eccentric of the internal gears. The pin has a cylindrical bearing portion engaging a cylindrical thrust member carried by the internal gear which is fixed to one of the shafts. This thrust member is coaxial with the shafts.
