Abstract

The invention relates to a device for reducing rattling noises in a toothed gear mechanism, comprising a toothed, annular spring element (3), which is resilient in the circumferential direction and is mounted on the side of the driven toothed gear (1) of a toothed gear pair facing away from the synchronization unit (2), the spring element having the same number of teeth and the same tooth geometry as the driven toothed gear (1) and being connected to the toothed gear (1) such that the teeth (6) thereof are disposed at an offset by a predetermined deviation angle with regard to the teeth (7) of the toothed gear (1) such that if the driven toothed gear (1) is engaged in the driving toothed gear (4) in the mounted state, the spring element (3) is pre-tensioned.
