The invention relates to the technical field of rail transit grounding equipment, in particular to a grounding device. The grounding device comprises a conductive inner ring, a conductive roller and a conductive outer ring. The conductive inner ring and the conductive outer ring achieve rolling friction contact through the conductive rollers arranged between the conductive inner ring and the conductive outer ring, the axle is sleeved with the conductive inner ring, and the conductive outer ring is electrically connected with a bogie frame of the railway vehicle. The non-working current of the rail vehicle and the bogie thereof is guided into the axle through the conductive outer ring, the conductive roller and the conductive inner ring, and then guided into the rail and the ground through the wheel pair. Compared with a grounding device with a friction disc and a carbon brush structure in the prior art, the grounding device disclosed by the invention can be conveniently mounted at the end part of the axle of the wheel set through the conductive inner ring, and the mounting is simple; meanwhile, the grounding device is in rolling friction, the friction force is small, and the friction loss of the grounding device is effectively reduced; and the maintenance periods of the grounding device and the axial device are effectively prolonged.
