Abstract

In a coupling tooth formation, in particular in a gear box, either on a gear sleeve or on a gear wheel, the teeth are fitted to the base end of a cylindrical base (12) in relation to the rotational axis, elongate in axial direction and provided at their coupling end with a roof outline sloping from the tooth base towards the tooth head, comprising a rounded roof edge (5); the radius of the roof edge rounding increases from the tooth base towards the tooth head according to a pre-set function in order to design the procedure of the tracking process after the initial contact as smoothly running as possible.
