Abstract:
1. Coupling arrangement having a rotational axis, about which the coupling arrangement can rotate, having: a first coupling element with a flat-side spur toothing system which extends axially with regard to the rotational axis and has first teeth which extend radially with respect to the rotational axis, a second coupling element with a flat-side corresponding toothing system which extends axially with regard to the rotational axis, engages axially into the spur toothing system, and has second teeth which extend radially with respect to the rotational axis, and at least one bracing means for bracing the first coupling element axially with the second coupling element, which coupling elements are fixedly connected to one another so as to rotate together about the rotational axis via the spur toothing system and the corresponding toothing system to transmit a torque, wherein at least one of the spur toothing system and the corresponding toothing system is configured in such a way that the first teeth and second teeth have tooth tip lines which are curved convexly in the axial direction away from a tooth root thereof between a radially outermost region and a radially innermost region of a tooth tip, and wherein the curved tooth tip is configured to be narrowest at a highest axial extent of the curved tooth tip as viewed in a circumferential direction of the coupling element with regard to the rotational axis.
