Abstract
A discharge device for discharging electric currents from a rotor part of a machine, in particular a rotor part with a shaft, into a stator part, the discharge device having a contact element, a support and a spring mechanism, the support being connectable to a stator part in an electrically conductive manner, the contact element being predominantly made of carbon, the contact element being accommodated on the support in an axially movable manner and connected to it in an electrically conductive manner, a contact force applicable to the contact element by the spring mechanism so as to establish an electrically conductive sliding contact between a sliding contact surface of the contact element to establish the sliding contact, and an axial shaft contact surface of the shaft, wherein the contact element is disk-shaped, the sliding contact surface being at least annular and disposable coaxially relative to the shaft contact surface.
