<p>The invention relates to a method for the production of a one-piece metal lic multiple wheel (2) for a traction mechanism, having at least two single wheels (3, 4) disposed next to each other, each having a wheel body (5, 6) w ith an exterior circumference (7, 8), wherein teeth (9, 10) are distributed across the outer circumference (7, 8) for engaging the traction mechanism, a nd wherein at least one of the at least two single wheels (3, 4) is configur ed as a chain, gear, or toothed belt wheel. The chain, gear, or toothed belt wheel is produced having a rough contour, wherein the tooth thickness of th e rough contour - in an axial view - is larger than the tooth thickness of t he final contour of the finished chain, gear, or toothed belt wheel, and thi s rough contour is then reformed by means of non-machining reforming, partic ularly by means of rolling, into the finished tooth contour as a function of the traction mechanism used, wherein a toothed belt wheel contour is produc ed from a chain wheel, or gear wheel contour, or a chain wheel contour is pr oduced from a gear wheel or toothed belt wheel contour, or a gear wheel cont our is produced from a toothed belt wheel or a chain wheel. The invention fu rther relates to a preform for the production of a multiple wheel, and to a multiple wheel.</p> |
