ABSTRACT:
A differential drive in which a reference sprocket is stationary for power drive and rotated for manual drive. In power drive, planet sprockets are orbited around the reference sprocket and rotated thereby. Drive planet sprockets on the same shafts drive an output sprocket at a slightly different ratio from the reference drive as they orbid around it, whereby there is a slow net rotation imparted thereto. In manual drive, the planet shaft axes are fixed and the reference wheel is rotated to drive the planet sprockets and rotate the output sprocket.
