Method for the production of a one-piece metallic multiple wheel, preform for the production thereof, and multiple wheel

A one-piece, multiple wheel for a traction mechanism from a metal material comprising at least one of at least two adjacently disposed single wheels configured as a finished sprocket wheel, a finished gear wheel, or a finished tooth belt wheel, each wheel comprising a wheel body, an outer circumference, and teeth with different geometry for engaging the traction mechanism are arranged in a distributed manner over the outer circumference, wherein the teeth geometry of the finished sprocket wheel, the finished gear wheel, and the finished toothed belt wheel have different teeth geometry, such that the two single wheels are configured for engaging different traction means, wherein at least one of the two single wheels is produced by non-machining reforming, the non-machining reforming comprising rolling, from a preform for a sprocket wheel contour, a gear wheel contour, or a toothed belt wheel contour, the preform having a rough contour configured in at least approximately an evolvent shape, and a tooth thickness of the rough contour, in axial view, is greater than a tooth thickness of a final contour of the finished sprocket, the finished gear wheel, or the finished toothed belt wheel, and wherein the finished toothed belt wheel can be produced from the preform for the sprocket wheel contour, the gear wheel contour, or the toothed belt wheel contour, further wherein the finished sprocket wheel can be produced from the preform for the gear wheel contour, the toothed belt wheel contour, or the sprocket wheel contour, further wherein the finished gear wheel can be produced from the preform for the toothed belt wheel contour, the sprocket wheel contour, or the gear wheel contour, whereby the metal material of the preform is brought at least partially from an area of an excess dimension of a tooth flank into a tooth head region, and a maximum dimension of an excess width in the area of excess dimension of the tooth flank can have a value selected from a range having an upper limit of 25% relative to the tooth thickness of the final contour.
