METHOD AND APPARATUS FOR MANUFACTURING A GEAR WHEEL WITH STUB TOOTHING

摘要

Method for manufacturing a gear wheel with stub toothing for a change-speed gearbox, wherein, in a first forming step, a gear wheel body (1) is drop-forged and the stub toothing is formed finally in at least one further forming step by cold calibration in the forging die by means of a forming tool (23) with forming parts which are arranged in a fan-shaped manner and the forming ends of which penetrate into the tooth spaces, wherein the forming parts are guided jointly between an upper and a lower receiving plate (29, 30) and are moved in a direction radially inwards in such a way that material is displaced out of the region of the tooth flanks into the tooth root regions.
