PURPOSE:To variably rotate an output part of a different planetary mechanism in no relation to an input shaft, by connecting a variable speed changer to one output part of the planetary mechanisms mutually connected with plural constitutional members responsively operated with the single input shaft. CONSTITUTION:When an input shaft 1 is driven at a fixed speed by a motor 12, if an output ring 4 is fixed, an output ring 5 is rotated as said before by a differential output, and if rotation of the ring 5 is controlled by a servo motor 11 so as to obtain the same rotary speed to the speed at this time, a rotary speed of the ring 4 becomes 0 even without receiving any brake force, then if a rotary speed of the ring 5 is decreased by the motor 11, the ring 4 begins to rotate, and if the ring 5 is stopped rotation or reversely rotated, the ring 4, that is, an output shaft 8 further increases its rotary speed. |
