Abstract
The invention relates to a flowturning device (1; 101) for producing an internal geared wheel (17) with inner toothing, one set of which is slanted. The workpiece (9) is held by a retaining member (16; 116) during shaping of the first inner toothing. The workpiece (9) is held by the first toothing on the first shaping toot (2; 102) during shaping of the second inner toothing. Once the internal geared wheel (17) has been finished, the rotational coupling between both shaping tools (2, 4; 102, 104) is detached. The internal geared wheel (17) is detached from the slanted toothing(s) by means of a stripping member (18).
