Abstract: A transmission (26) of continuously-engaged gear teeth of standard gear design is provided for infinitely or steplessly varying the ratio of output angular velocity to torque across a range which can include zero output angular velocity. In one embodiment, the transmission comprises a planetary gear assembly including planetary gear (28), intermediary gear (30) and sun gear (32).

Novel mechanisms are provided for varying the orientation of the planetary gear (28) and for interconnecting the planetary shaft (110) to the orbital shaft (62).
