ABSTRACT:
A variable-ratio gear assembly comprising an input shaft, an output shaft, and at least two intercoupled independently-variable coplanar reverted gear train loops coupled to the input and output shaft. Each coplanar reverted gear train loop comprises a torque input member, a torque output member and a reactive member. A clutch is coupled to the coplanar reverted gear train loops for independently switching at least two of the members from coupling to one of the casing of the gear assembly, the input shaft and the output shaft to coupling to another of the casing, the input shaft and the output shaft for varying the velocity ratio of the coplanar reverted gear train loops.
