Abstract

The invention relates to a coupling toothing in a gearbox between two rotationally symmetrical coupling structures (5,6) which can be coupled with each other. The toothing comprises the following features to increase the strength thereof: (a) both coupling structures (5,6) have claws on opposing sides which project axially from a base surface (10); (b) in a first of the two coupling structures (6), the claws (14,15,16) are arranged on the inner peripheral surface (17) of an outer collar (18) delimiting the base surface (10); (c) in the second of the two coupling structures (5), the claws (7,8) are arranged on the external periphery surface (9) of an inner collar (13) delimiting the base surface (10); and (d) the coupling surfaces of the two claws each have an undercut profile.
