Discharging device for discharging electrical interference

A discharging device (10, 26, 40, 60, 70, 80, 90) for discharging electrical interference, in particular currents, from a rotor part of a machine, said rotor part in particular being a shaft (18), into a stator part (17) of the machine, the discharging device having a contact device (11, 41, 91) comprising a contact element (13, 27, 43) which is accommodated in an axially displaceable manner in a guide and which is acted on by a contact force device (15, 28, 44) for generating a shaft contact force FW in order to establish electrical contact between a shaft contact surface (19, 29, 47, 92) of the contact element (13, 27, 43) and a rotor contact surface (20, 30, 48, 61, 71, 81) of the shaft (18),

• characterized in that
• the guide has a stator contact surface (25, 36, 50) for forming an electrical connection with the stator part (17) and the discharging device has a guide contact force device (21) for generating a guide contact force FF between a guide contact surface (24, 35, 49) of the contact element (13, 27, 43) and the stator contact surface (25, 36, 50) electrically connected to the stator part (17).
