1. A transmission for an on-load tap-changer, the on-load tap-changer comprising a motor with an output shaft and a diverter switch with a drive shaft, the transmission comprising:
a cam disk;
a drive gear wheel; and
a roller, which is coupled to the drive gear wheel,
wherein the cam disk is connected in a rotationally fixed manner to the output shaft and the output shaft lies on a rotation axis of the cam disk,
wherein the drive gear wheel is connected in a rotationally fixed manner to the drive shaft,
wherein the cam disk has an inner contour and an outer contour, the inner contour and the outer contour being configured to be followed by the roller,
wherein the inner contour and the outer contour each have a first region with a constant radius of curvature and a second region in which a distance of a respective contour from the rotation axis of the cam disk changes, and
wherein the roller is configured such that, in an event of a rotational movement of the cam disk, the roller follows the inner contour and the outer contour in such a way that the roller follows a portion of the first region of the outer contour, thereafter follows a portion of the second region of the outer contour and thereafter follows a portion of the first region of the inner contour.
