The invention relates to a method for machining a toothing (7) on an outer circumference (6) or an inner circumference of a work piece (2) made of pressed and sintered powder metal, by means of a rolling process on the toothing (7) using two rotatable section rolling wheels (8), which comprise a formed toothing (13) engaging in the toothing (7) of the work piece (2). Two section rolling wheels (8) are rotatably arranged with at least approximately constant center distances (16) from each other between the section rolling wheels axles (9) in a common supporting frame (10). The invention further relates to a device for a rolling treatment of a toothing.
L'invention concerne un procédé d'usinage d'une denture (7) sur une périphérie extérieure (6) ou une périphérie intérieure d'une pièce (2) en métal pulvérulent comprimé et fritté, ce procédé comprenant une opération de laminage réalisée sur la denture (7) au moyen de deux roues de laminage de profilés (8) rotatives qui présentent une denture profilée (13) s'engrenant dans la denture (7) de la pièce (2). Selon l'invention, les deux roues de laminage de profilés (8) sont disposées de façon rotative dans un cadre support (10) commun, l'entraxe (16) entre les axes (9) des roues étant au moins sensiblement constant. L'invention concerne également un dispositif d'usinage d'une denture par laminage.
