A set of bearing pins (6) is arranged at a distance from the gears, where one of the pins comprises a diameter over a part of its axial extension. The diameter lies in a region of 90 to 100 percent of root diameter of toothing of associated gears. The gears and the bearing pins are manufactured from a workpiece.
