Roller bearing arrangement for railway vehicles with current lead-through

摘要

The arrangement has a roller bearing (2) with one or more rows for transferring a load and an adjacent device for transferring current from the casing to the axle. The current transfer device consists of an additional inclined roller bearing (5) insulated from the main roller bearing with an inner ring (5''') seated rigidly on the shaft (1) and with an insulating bush (6) or a gap between the outer ring (5') and a casing (3) or cover (4). The insulating bush is bridged at one or more points on the cover periphery by a connecting device (8) that is electrically insulated with respect to the casing or cover.
