Abstract:
A process for powder metallurgic manufacture of a coupling body with a crown of coupling teeth, whose flanks extending from wedge-shaped end faces are in relief, such that a formed body with coupling teeth, which have wedge-shaped end faces and axis-parallel flanks, is pressed:out of a sintering powder and sintered to a molded blank, whose coupling teeth for forming the flank reliefs are subjected to axial compression molding between two form tools on the one hand for the wedge-shaped end faces and on the other hand for the flank reliefs, characterized in that during the compression molding of the flank reliefs in a transition region between the flanks and the wedge-shaped end faces a flank-side interlocking shoulder, with a rounded transition to the wedge-shaped end faces and lying in the molding surface of the form tools, is impressed into the flanks of the coupling teeth.
