Claim 5:
6. A method (1000) for producing a sprocket (1, 1′) for transferring a drive power from a drive shaft, in particular from a drum motor (800), to a plastic modular belt (900), the sprocket (1, 1′) comprising at least one toothed ring (110) and an outer ring (200, 200′), which adjoins the toothed ring (110), and an inner ring (300, 300′), wherein the inner ring (300, 300′) and the outer ring (200, 200′) are connected to one another by means of webs (410, 410′), the method is characterized in that
at least one toothed ring (110) and an outer ring (200, 200′) are formed, which adjoins the toothed ring, and an inner ring (300, 300′), wherein the inner ring (300, 300′) and the outer ring (200, 200′) are connected to one another by means of webs (410, 410′),
characterized in that the toothed ring or the toothed rings (110, 120) and/or the outer ring (200, 200′) and/or the inner ring (300, 300′) and/or the webs (410, 410′) and/or an intermediate disk (430) and/or the first cover disk (510) and/or the second cover disk (520) are produced from solid material, in particular plastic or metal, wherein the toothed ring or the toothed rings (110, 120) and/or the outer ring (200, 200′) and/or the webs (410, 410′) and/or the intermediate disk (430) and/or the first cover disk (510) and/or the second cover disk (520) preferably are or have been produced from and/or with plastic, and/or wherein the inner ring (300, 300′) preferably is or has been produced from and/or with metal, and/or
characterized in that the toothed ring or the toothed rings (110, 120) and/or the outer ring (200, 200′) and/or the inner ring (300, 300′) and/or the webs (410, 410′) and/or the intermediate disk (430) and/or the first cover disk (510) and/or the second cover disk (520) are produced in an injection-molding process, wherein the toothed ring or the toothed rings (110, 120) and the outer ring (200, 200′) and the inner ring (300, 300′) and the webs (410, 410′) and the intermediate disk (430) are preferably produced in a single, common injection-molding step, and/or
characterized in that the toothed ring or the toothed rings (110, 120) and/or the outer ring (200, 200′) and/or the webs (410, 410′) and/or the intermediate disk (430) and/or the first cover disk (510) and/or the second cover disk (520) are or have been produced in an injection-molding process, wherein the toothed ring or the toothed rings (110, 120) and the outer ring (200, 200′) and the webs (410, 410′) preferably are or have been produced in a single, common injection-molding step, and/or wherein the toothed ring or the toothed rings (110, 120) and the outer ring (200, 200′) and the webs (410, 410′) preferably are or have been injection-molded onto the inner ring (300, 300′), and/or
characterized in that a semi-finished sprocket product is initially produced which has, proceeding from a center point, production webs (500), in particular exactly three production webs (500), which preferably connect an injection point corresponding in particular to the center point, and/or two or more injection points assigned in each case to one or more production webs, to the inner ring (300, 300′) and/or the webs (410, 410′).
