BRUSH HOLDING ASSEMBLY FOR A CARBON BRUSH, AND ELECTRICAL MACHINE EQUIPPED WITH A BRUSH HOLDING ASSEMBLY OF THIS TYPE

摘要

The invention relates to a brush holding assembly for carbon brushes (1) in an electric motor or electric generator and to an electrical machine equipped with a brush holding assembly of this type. According to the invention, the carbon brush (1) is placed against a commutator of the machine by means of a spring (2) in order to transfer current, and a retaining and guiding system (8) having lateral guide surfaces (4) is provided for preventing a lateral movement of the carbon brush (1). In addition, a guide section (5) that interacts with said guide surfaces (4) is provided on the side of the spring, and the carbon brush (1) is fastened to the spring (2) while being located at a gap-forming distance from the guide surfaces (4). A paste for lubricating and damping noises is provided between the guide surface (4) and the guide section (5) of the spring (2).
