The invention relates to a device for grounding a shaft, in particular a rotor shaft of an electric machine, comprising a grounding hub (17) via which the shaft to be grounded is electrically conductively connected to ground, preferably a housing (9). In order to now achieve reliable grounding with low production costs, a separate guide element (30) is fastened to the grounding hub (17), which guide element fixes the grounding hub (17) in the rotational direction and/or limits a movement of the grounding hub (17) in at least one axial direction. The invention also relates to a transmission, to an electric axle drive unit for a motor vehicle, and to an electric machine, in which the aforementioned device is implemented.

    本发明涉及一种用于将轴、尤其是电机的转子轴接地的装置,该装置包括接地毂部(17),要被接地的轴经由该接地毂部与地、优选壳体(9)导电连接。现在为了在低制造耗费的情况下实现可靠接地,在接地毂部(17)上固定单独的引导元件(30),该引导元件将接地毂部(17)在旋转方向上固定和/或限制接地毂部(17)在至少一个轴向方向上的移动。本发明还涉及一种变速器、一种用于机动车的电的车桥驱动单元和一种电机,在它们之中实现上述装置。
