1. A shaft grounding arrangement (X), comprising:
a housing (GG);
a shaft (W, GW2, DS1, DS2) supported in the housing (GG) and protruding from the housing (GG);
a shaft grounding device (E) configured for establishing an electrically conductive contact (SK) between the shaft (W, GW2, DS1, DS2) and the housing (GG); and
a cover (C) fixedly connected to the shaft (W, GW2, DS1, DS2) and configured for protecting the shaft grounding device (E) against environmental influences, the cover (C) at least partially surrounding the shaft grounding device (E),
wherein the shaft grounding device (E) is fixedly connected to the housing (GG), and the electrically conductive contact (SK) is formed by a sliding contact between contacts (EK) of the shaft grounding device (E) and a surface of the cover (C).
