Abstract

A contact-making rotary transmission includes a brush forming an electrically conductive sliding contact element and a contact path of electrically conductive material for contact with the brush. The brush is guided and/or held by an arrangement which includes a plurality of carrier segments arranged axially behind one another. Each carrier segment has attached thereto a brush receptacle such as to define a first gap between the carrier segment and the brush receptacle. The brush receptacle includes a stationary receiving shaft which is formed by walls and configured to receive the brush, and a guide element which is provided on a wall of the receiving shaft so as to define a second gap between the brush and the wall. At least one of the walls includes an opening in communication with the first and second gaps to allow a flow of cooling air for cooling the brush.
