ABSTRACT:
A planetary worm type gear system in which an integrated worm type gear on a first shaft is driven by a worm set on another shaft, or a separate coaxially driven worm and gear set. The planetary worm type gear system has two or more worm-gears coupled to a ring type internal worm set, and a shaft driven by the ring type internal worm set for output. Alternatively, a rotor arm around the shaft may be driven by the two or more worm gears for rotary output, or both can be driven for differential output.
