Claim 0:
1. A gearwheel for structure-borne sound reduction in electric drives, comprising:
a toothed ring; and
a wheel hub, which has a structured annular or corrugated web between a shaft seat and the toothed ring,
wherein the structured annular or corrugated web has a structure with deviations from uniform mass distribution about an axis of rotation of the gearwheel, and
wherein the structured annular or corrugated web has an axial symmetry to avoid imbalance,
wherein the structured annular or corrugated web has adjacent, differently structured sectors with different stiffness and mass distribution, which are present in pairs and can be brought into congruence after a rotation of 180° about the axis of rotation of the gearwheel.
