Auxiliary gear for motors with high RPM for auxiliary drive units e.g. used with seat back raking mechanism of motor vehicle seat

摘要

At least one additional eccentric disc (34) effecting mass balancing is axially connected to a second eccentric disc (13) supporting a spur gear (15). The second eccentric disc is connected and torsionally fixed to the drive shaft (11) of the motor (10) in such a way, that the highest eccentric points of the two discs lie diametrally opposite one another. A spur gear, forming a transmission element between drive components (14,27), may be mounted on the second eccentric disc and engages in the inner tooth of an internal ring gear (17).
