ABSTRACT:
An eccentric reduction gear for a vehicle window winder system has a ring gear, a planet pinion that is eccentric relative to the ring gear, a drive component that drives the planet pinion and the ring gear so that they roll relative to each other, and a winding drum attached to the planet pinion. A transmission component is wound around the winding drum and drives a vehicle window. The reduction gear provides a high reduction ratio in a small space and also ensures that the movement cannot be reversed.
