The gear assembly can be operatively connected on the input side to a drive machine and on the output side preferably to an actuating element of the electrically operable brake and comprises at least one gear stage. The at least one gear stage comprises at least two intermeshing gear wheels, of which at least one gear wheel is rotatably mounted on an axle element by engagement of the axle element in a receptacle of the at least one gear wheel. The receptacle and the axle element have mutually corresponding peripheral surfaces, of which, in the axial direction, at least one peripheral surface has an outwardly curved contour and the other peripheral surface has a contour designed such that the peripheral surfaces roll against one another on the contours in order to bring the at least one gear wheel and the axle element into an oblique position relative to one another.
