摘要
A gear wheel includes multiple helical toothings, each having a different helical angle. A pressing method for molding a gear wheel involves introducing a compactable material into a chamber of a pressing tool, compacting the material, exposing the helical toothings of the gear wheel, and removing the molded body from the pressing tool. A pressing tool for pressing, as one part, a gear wheel, includes a matrix, cylindrical first and second molding tool parts which can be translated along and then rotated about a longitudinal axis, and a driver coupled to the molding tool parts or driving them. The molding tool parts can be moved towards and away from each other and the inner surface of the matrix delimits the chamber and is shaped to allow a linear axial sliding movement of the compactable material relative to the matrix.
