Abstract
A hybrid transmission provides a continuous range of reduced output speeds in a coaxial relationship about a common central axis within a surrounding cylindrical housing. The input shaft speed is increased through a planetary transmission having a sun gear fixed to a variable eccentric shaft. The eccentric shaft is surrounded by an orbiter and spaced anchor and drive vanes, which are interconnected by a plurality of anchor and drive vanes. Output speed is varied by change of the degree of eccentricity, using a worm gear drive interposed between inner and outer eccentrics within the eccentric shaft. control is achieved through shift rings that rotate a worm in response to external cable tension.
