Device for avoiding backlash in toothed gearings

摘要

The drive gearwheel (1) has through several bores (13) and is fitted with a ring bar (4). The adjoining gear wheel (2) has several through bores (17) associated with the bores of the drive wheel and a force ring (3) with several socket bores (14) is connected to the co-running gearwheel (2). Spring elastic elements (8) fixed at one end on the ring bar pass through the bores in the drive gear wheel and co-running gearwheel and into the socket bores of the force ring to exert a force through which the two gearwheels are pretensioned in opposite directions.
