Gear for reducing structural noise in electric drive

The invention relates to a gear wheel (1) for reducing structural noise in an electric drive, comprising a ring gear (11) and a hub (12) which has a structured ring-shaped or corrugated bridge (14) between an axle seat (13) and the ring gear (11), characterized in that the bridge (14) has such a structure that the bridge (14) is connected to the ring gear (11) and the ring gear (11). Said structure is configured to differ from a uniform stiffness and mass distribution about the axis of rotation (16) of the gear (1), and has an axial symmetry to avoid imbalance, a periodic axial symmetry of double, quadruple, sextuple or octuple. 本发明涉及一种用于降低在电驱动装置中的结构噪声的齿轮(1)，齿轮具有齿圈(11)和轮毂(12)，轮毂在轴座(13)和齿圈(11)之间具有结构化的圆环形的或瓦楞形的桥接部(14)，其特征在于，-桥接部(14)具有这样的结构，即，所述结构构造成与绕齿轮(1)的旋转轴线(16)均匀的刚性和质量分布有区别，并且-具有轴对称性以避免不平衡，-具有二重的、四重的、六重的或八重的周期性的轴对称性。
