Abstract
A discharging device for discharging electrical interference, in particular currents, from a rotor part of a machine, said rotor part in particular being a shaft, into a stator part (17) of the machine, the discharging device having a contact device (11) comprising a contact element (13) which is accommodated in an axially displaceable manner in a guide and which is acted on by a contact force device (15) for generating a shaft contact force (FW) in order to establish electrical contact between a shaft contact surface (19) of the contact element (13) and a rotor contact surface (20) of the shaft (18), wherein the guide has a stator contact surface (25) 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) of the contact element (13) and the stator contact surface (25) electrically connected to the stator part (17).
