Abstract
A shaft grounding arrangement (X) includes a housing (GG), a shaft (W, GW2, DS1, DS2) supported in the housing (GG), a shaft grounding device (E) for establishing an electrically conductive contact (SK) between the shaft (W, GW2, DS1, DS2) and the housing (GG), and a covering element (C) fixedly connected to the shaft (W, GW2, DS1, DS2) for protecting the shaft grounding device (E) against environmental influences. The covering element (C) at least partially surrounds the shaft grounding device (E). The shaft grounding device (E) is fixedly connected to the housing (GG). The electrically conductive contact (SK) is formed by a sliding contact between contact elements (EK) of the shaft grounding device (E) and a surface of the covering element (C). A transmission (G) may include the shaft grounding arrangement (X) of this type, and an electric axle drive (EA) may include the transmission (G).
