▎ 摘　　要

NOVELTY - The arrangement (1) has a roller bearing (2) which is provided with an inner ring (3), an outer ring (4) and rolling elements (5). The inner ring comprises an inner ring raceway (6), the outer ring comprises an outer ring raceway (7), and the rolling elements are rollingly mounted between the inner ring and the outer ring. An electrically conductive element (8) is arranged between the inner ring and the outer ring, and is configured to connect the inner ring to the outer ring in an electrically conductive manner. The current-conducting element comprises a spongy support structure (9) lying in the current flow, which is provided at least in sections with a coating that contains graphene or is formed entirely from graphene. USE - Arrangement of rolling bearing used for fixing axles and shafts. ADVANTAGE - The arrangement provides protection against harmful bearing currents in a wet-running roller bearing arrangement. It provides low-friction protection against the harmful bearing current. The graphene-coated sponge-shaped carrier structure forms a water-repellent surface and at the same time has very good electrical conductivity. Due to its advantageous adsorption properties, it absorbs and binds oils and fats. The risk of an electrically non-conductive oil film building up between the spongy support structure and a bearing ring can be reduced. The porous, cell-like structure and the inner surface of the bearing ring cause a large number of electrically conductive contact points to form a bearing, which ensures permanent electrical conductive, even with wet rolling bearings. The coating that contains graphene or is formed entirely from graphene is in particular also found. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view of the roller bearing arrangement.
