ABSTRACT:
A device for non-cutting manufacturing of an annular part having external teeth includes a core tool that supports the blank from which the annular part is manufactured and is axially displaceable between two profiling rollers arranged diametrically opposite each other, and a separate rotating drive for each of the core tool and the two profiled rollers. The device further includes a computer element which controls the three rotating drives for synchronizing rotational speeds of the core tool and the two profiling rollers. The computer element also controls radial adjustment of the two rollers with their respective full-height regions with respect to the core tool by a calibration amount at the conclusion of the shaping operation.
