VERFAHREN UND VORRICHTUNG ZUM HERSTELLEN EINES ZAHNRADES

摘要

There are described a method and an apparatus for producing a gear wheel from a powder metal blank (1) pressed and sintered with an overmeasure in the toothing area, which powder metal blank is compacted under a plastic deformation in the vicinity of the overmeasure by pressing against a counter-toothing (8) of at least one rotating pressing tool (3) by the overmeasure, which counter-toothing engages in the toothing (9) of the powder metal blank (1). To create advantageous constructional conditions it is proposed that the counter-toothing (8) designed as internal toothing of the annular pressing tool (3) enclosing the powder metal blank (1) is pressed into the toothing (9) of the powder metal blank (1) by means of a pressure roller rolling on the outside periphery (10) of the pressing tool (3).
