Abstract
The invention relates to a method for the production of a one-piece, metal multiple wheel (2) for a traction mechanism comprising at least two adjacently disposed single wheels (3, 4), each comprising a wheel body (5, 6) having an outer circumference (7, 8), wherein teeth (9, 10) for engaging the traction mechanism are arranged in a distributed manner over the outer circumference (7, 8), and wherein at least one of the two single wheels (3, 4) is configured as a sprocket, gear or toothed belt wheel. The sprocket, gear or toothed belt wheel is produced with a rough contour, wherein a tooth thickness of the rough contour (17), in axial view, is greater than the tooth thickness of the final contour of the finished sprocket, gear or toothed belt wheel and thereafter depending on the traction means used, this rough contour is reformed by non-machining reforming, in particular by rolling, into the finished tooth contour, wherein a toothed belt wheel contour is produced from a sprocket wheel or gear wheel contour or a sprocket wheel contour is produced from a gear wheel or toothed belt wheel contour, or a gear wheel contour is produced from a toothed belt or sprocket wheel.
