Device for stepping up and stepping down a gear system comprises a fixed tube (1) which is connected to the housing of the drive element. Preferred Features: A drive segment (2) has three balls (3) which are clamped in a three-point position to form a rolling frictionally engaged power connection. The necessary force for the frictional engagement is produced from the angle of the drive segment (50).
