Gear part and method for forming a gear part

Abstract

A gear part and method is provided for forming a gear part, in which a circular blank-like workpiece is fixed in a flow-forming machine in a radially inner area, the circular blank-like workpiece is rotated, at least one roller is substantially radially moved, in which during the radial moving in workpiece material flows radially, so that the workpiece wall thickness is reduced in this area, in a central area of the workpiece a boss is formed and during radial moving in the roller is increasingly axially infed. The method also relates to forming a gear part in which the circular blank edge is thickened by at least one forming roller, the shaping of the circular blank edge taking place through the contour of gripping jaws and/or the forming roller and the cross-section of the circular blank edge is formed in an approximately rectangular manner.
