Abstract
A device for compensating for the tooth backlash between two toothed gears in engagement with one another, with a toothed disk, which is connected in parallel with one of the toothed gears and provided with the same gear pitch, and which is held such that it can be hydraulically adjusted relative thereto until it bears against the non-force-transmitting tooth flanks of the mating toothed gear. In order to achieve a design that is as simple as possible and requires little mounting space, there must be provided at least one hydraulic adjusting element, which exerts an adjusting force in circumferential direction on the toothed gear and which is equipped with a steel piston held adjustably in a housing and urged by a spring as well as by pressurized fluid supplied via a check valve.
