Claim 3:
4. 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′),
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 a first cover disk (510) and/or a second cover disk (520) are composed of 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) are preferably composed of plastic and/or comprise plastic, and/or wherein the inner ring (300, 300′) is preferably composed of metal and/or comprises 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 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′) are preferably 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′) are preferably injection-molded onto the inner ring (300, 300′), and/or
characterized in that the cavities (420) between the webs (410, 410′) are free from filling material.
