Transmission with high ratio

摘要

The gear has a threaded spindle (24) driven by at least one nut (20). The threaded spindle curves along a circular track (28) and is rotatable relative to the nut around the center point of this circular track. The thread has a driven element (32) which is moved along by the threaded spindle and upon which is made available a force or a torque on a radius which is reduced in relation to the circular track. A tension element is mounted on the driven element on the driven side.
