Abstract:
The invention relates to a method for producing a toothed wheel (1) in net shape or near-net shape quality, in particular a chain wheel, for a VVT system from a powder, with the toothed wheel (1) having an at least approximately cylindrically shaped housing (2) which is delimited in axial direction by one respective end face (6, 7) and which has an outside surface (3), and at the outside surface (3), a toothing (8) having teeth (9) and tooth roots (10) between the teeth (9) is embodied at a distance to both of the end faces (6, 7), and the toothing (8) has a tooth root circle (25) having a tooth root circle diameter, and the powder is filled into a mold (28) and pressed by means of at least one punch, and protrusions (11, 20) are embodied at least in the region of the teeth (9) at the outside surface (3) of the housing (2) and projecting over the latter in radial direction.
