Patent ID: 8876427

Claim:
In a coupling element having a spur toothing formed on the coupling element for transmitting torque about a rotational axis, the spur toothing engagable axially into a corresponding mating toothing, the improvement comprising: spur teeth comprised of plastically formable material, wherein the spur teeth are formed on a first section that comprises an annular bead which projects axially outwardly from a base on the coupling element and which has the teeth at least proportionally on an axial end side, which faces axially outwardly from the coupling element in the direction of the rotational axis and the first section projects such that an axially open annular groove is formed radially between the first section and a second section which projects axially outwardly from the coupling element, the second section being spaced radially inwardly from the first section, the second section extends axially and radially outwardly from the coupling element so as to form the open annular groove radially between the first and second sections, and the base has a spacing between a radially outer contour of the first section and a radially inner contour of the first section, and the teeth have an overall length in a tooth root plane, wherein an axial projection of the overall length of the teeth is greater than an axial projection of the spacing of the base.
