Abstract
A tool for producing a gear part having external toothing using a method of shaping by compression or by rolling. Said tool comprises a receiving tool for supporting the work piece which is impinged upon by a projection. Said receiving tool is driven to perform a rotational movement. The tool includes a roller pivotal about an axis (Y) that is parallel to the axis (X) of the rotating receiving tool which hold the work piece. The roller can be adjusted in the direction of its Y axis in relation to the work piece. It is subdivided in the direction of its Y axis in order to carry out the compression method. The tooth height of the individual shaping areas increases while the crown circle remains the same across all shaping areas. The root radius of the individual shaping areas decreases and the tooth depth increases from one shaping area to the next shaping area. As a result, the tooth thickness at the root circle increases in all of the shaping areas.
