A differential motion gear system to control the output speed ratio by changing the input direction. The gear system utilizes a planetary gearset to achieve the desired results. The input shaft may be directly connected to the sungear, the differential motion gear set, or to the ring gear. One or more one-way drive mechanisms are connected between a stationary case and one or more of the planetary gearset elements and between the planetary gearset elements and the output shaft. Selective braking of the planetary gearset elements, in conjunction with the change of direction of the input shaft causes the output shaft to rotate in a single direction, but at different output speeds.
