Abstract

A device for avoiding gear flank backlash or chattering of first and second gear trains. Each of the gear trains include a plurality of mutually meshing gear wheels. The first gear train has a first initial wheel and a first end wheel. The first initial wheel is driven. The second gear train has a second initial wheel and a second end wheel. The second end wheel is driven. The first and second initial wheels of the first and second gear trains are non-rotatably connected to one another. A tensioning device is connected between the first and second end wheels and it produces a torque in a preferred rotational direction of the gear wheels of the first gear train. The torque acts between the first initial wheel and the first end wheel and ensures a definite flank alignment of the gear wheels during the operation of the first gear train.
