Abstract
A method and an apparatus are described for producing a gear wheel from a powder metal blank () which is sintered and pressed with an overmeasure in the flank and root region of the teeth and which in the region of the overmeasure is densified under plastic deformation by the overmeasure by pressing in a counter-toothing () of a pressing tool () which engages in the toothing (). In order to provide advantageous conditions it is proposed that during the plastic deformation of the flank or foot region of the tooth, the tip surface of the respective tooth is subjected to a pressure force counteracting an extension of the tooth.
