Abstract
A method for producing a sintered component in the form of a workpiece having teeth, wherein crowning, with a central region and end regions, is formed in flanks of teeth, the tooth thickness being smaller in at least one of the end regions than in the central region of the flanks. In order to form the crowning, at least one pressing punch acts on the teeth, which are located in a die, along a first axis such that the teeth are sized at least to the central region by means of axial pressing.
Claims15
A method for producing a sintered component in the form of a workpiece having teeth, each tooth having:
- a longitudinal axis, and opposing end faces disposed on the longitudinal axis, wherein a distance between the end faces defines a width of the tooth,
- opposing flanks extending between the end faces, wherein a distance between the flanks defines a thickness of the tooth,
- a crowning formed in the flanks, and extending along the width of the tooth, the crowning having a central region and end regions formed in the flanks, the tooth thickness being smaller in at least one of the end regions than in the central region,
- wherein the tooth is disposed in a die, and a pressing punch acts on the tooth along the longitudinal axis by a pressing punch to form the crowning along the width of the tooth, such that the tooth is calibrated to an exact fit, at least in the central region, by means of axial pressing.
