ABSTRACT:
A modified planetary gear assembly includes a sun gear, planetary gears, an internally-toothed ring gear and a carrier, and can either transmit or not transmit torque from the sun gear to the carrier. The internally-toothed ring gear has outer peripheries on both sides suitable for being supported by a bearing device and a middle groove on the outer surface having timing teeth shaped around the groove. The peripheries are supported by a bearing device. A stopper device which is movable in a radial direction is mounted at a point around the middle groove. When the stopper device is moved forward to engage with the timing tooth, the internally-toothed ring gear is fixed and torque is transmitted from the sun gear to the carrier. When the stopper device is retracted, the internally-toothed ring gear freely rotates and no torque is transmitted. Thus, there are two states of torque transmission. The rotation speed of the internally-toothed ring gear is inversely determined by the rotation speed of the sun gear and the carrier.
