Abstract
A method for manufacturing a hollow wheel equipped with an internal gear toothing, wherein a work-piece includes a tubular section with a longitudinal axis, by which the term radial utilized in the following is defined. By N≧2 stamping tools, of which each one during the implementation of the method is brought into a working position, the tool for producing the gear toothing is processed on the inside of the tubular section, wherein the work-piece carries out a rotating movement with a rotation speed varying in time around the mentioned longitudinal axis and at least one stamping tool in the working position carries out radially oscillating movements, which are synchronized with the mentioned rotating movement. The at least one stamping tool in the working position processes the work-piece repeatedly.
