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 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 a fixed rotation position relative to each other and which face gears are together axially displacable, a first cylindrical pinion with an axis of rotation at a right angle to the first axis of rotation, which first pinion is in mesh with the first face gear with a first tooth clearance, and a second cylindrical pinion whose axis of rotation is parallel to the axis of rotation of the first cylindrical pinion, which second pinion is in mesh with the second face gear with a second tooth clearance, while the input or the output shaft being connected to the first pinion, said gear transmission capable of transmitting a torque in both directions of rotation, wherein the toothings of the face gears and the pinions in mesh therewith are designed such that the first tooth clearance is greater than the second tooth clearance.
