Abstract
The invention concerns a gearwheel (1) with a gear rim (2) and an insert (3) whose external diameter (d3) is greater than half of the external diameter (d1) of the gearwheel (1), wherein the insert (3) is surrounded by injection molding by means of a cone mold during the manufacture of the gearwheel. In particular, the gear rim (2), including gear teeth on the external circumference, is formed at the same time during the injection molding process.
