ABSTRACT:
A technique for modifying an input rotation in continuously variable increments to produce a controlled rotational output is disclosed herein. This technique combines epicyclic motion of a series of planetary shafts in a parallel fashion in order to produce continuous, controlled, intermediate output in the same direction and at the same speed or a greater speed than the input rotation. This intermediate output is then modified to produce a continuous, controlled, final rotational output only when the intermediate output is greater in speed than the input. The final output can be in the same direction as the rotational input and at a speed which is proportionate to the excess speed of intermediate output.
