ABSTRACT:
A rotary motion transmitting device having oppositely disposed toric discs mounted on its input and output shafts. Motion transmitting rollers are frictionally engaged between the toric discs for transmitting motion from one toric element to the other and tension sheets extend between opposite rollers to balance forces exerted on the rollers. Pivotal roller supports are interconnected by correlating means which point limited independent pivotal movement of the roller supports while resiliently forcing the supports into the same angular positions. Also means are provided for controlling the transmission ratio such that the output torque assumes a desired value.
