ABSTRACT:
An apparatus for transmitting rotary power includes first and second discret sources of rotary power and a pair of intercoupled first and secondary planetary gear assemblies, each having a primary driving member, secondary driving member and driven follower member. The primary driving member, secondary driving member and driven follower member correspond to one of the following elements: ring gear, sun gear and planetary carrier cage. The primary driving member of the first gear assembly is driven by the first source of rotary power. The secondary driving members of both gear assemblies are driven by the second source of rotary power. The driven follower member of the first assembly is coupled to the primary driving member of the second assembly and the driven follower member of the second assembly, which drives the output shaft, is other than the carrier cage. A drive shaft velocity control controls the absolute speed of at least one of the first and second sources of rotary power without affecting the speed of the other. The relative speeds of the two sources of rotary power can be controlled within a narrow speed range close to the optimum speed of the power source(s) employed and yet produce a broad range of output speeds at the output shaft.
