Gearwheel for structure-borne sound reduction in electric drives, having a toothed ring and a wheel hub, which has a structured annular or corrugated web between a shaft seat and the toothed ring. The web has a structure designed with deviations from uniform stiffness and mass distribution about an axis of rotation of the gearwheel, and has an axial symmetry to avoid imbalance. The gearwheel has a two-fold, four-fold, six-fold or eight-fold cyclic axial symmetry.
