ABSTRACT:
Gear transmission between an input shaft and an output shaft, comprising a first and second face gear which are rotatable about a first axis of rotation and have identical toothing as regards number of teeth and module, which face gears are mounted at an adjustable distance from each other with the toothing facing each other and with an essentially fixed rotation position relative to each other, comprising a first cylindrical pinion with an axis of rotation at right angles to the first axis of rotation, which first pinion with a first tooth clearance is in mesh with the first face gear, and comprising a second cylindrical pinion whose axis of rotation is parallel to the axis of rotation of the first cylindrical pinion, which second pinion with a second tooth clearance is in mesh with the second face gear while the input or the output shaft is connected to the first pinion. The toothings of the face gears and the pinions in mesh therewith are designed in such a way that after theoretically correct setting of the toothings the first tooth clearance is greater than the second tooth clearance.
