摘要

The device has a drive wheel (6), an output wheel (7) coaxially arranged to drive wheel and a transmission wheel arranged between the drive wheel and the output wheel and aligned coaxially to the drive wheel and the output wheel. A double wheel (2) is provided which consists of two gear wheels (10,11) with two teeth (Z2,Z3) and a bearing dome arranged between the gear wheels. The external geometry of the bearing dome is as large as the tip circle diameter of the gear wheels.
