PURPOSE:To increase the revolution speed of a trailing shaft by the increase of the resistance of the fluid in a body which is generated by the operation of a valve by constituting the captioned apparatus from gear pumps which perform planetary movement. CONSTITUTION:A gear 7 fixed at the top edge of a trailing shaft 8 is installed inside a casing 9 which is fixed onto a motion shaft and revolved. A plurality of gears meshed with the gear 7 are arranged and carry out planetary movement in the sealed casing. Each shaft constitutes plurality of gear pumps, and a flow-rate control valve is installed, and speed change is performed by increasing and decreasing fluid resistance. Therefore, the frictional resistance is not applied from outside, and the transmission efficiency can be improved. |
