<p>In a face gear transmission with a cylindrical pinion and a face gear meshing therewith the toothing of the face gear is derived from a theoretical profile (22) of a pinion with an infinitely small thickness by moving the centre of this pinion along an imaginary axis which then coincides with the axis of rotation of the cylindrical pinion. The teeth of the face gear are crowned so as to achieve the required tooth clearance. The shape of the teeth of the face gear is such that upon the movement of the theoretical pinion profile (22) in the direction of the imaginary axis of rotation, starting from a defined diameter between the maximum and the minimum diameter of the toothing of the face gear, the centre of the theoretical pinion profile undergoes a displacement (p1, p2) at the same time at right angles to the imaginary axis of rotation in the direction towards the toothing of the face gear.</p> |
