Bearing arrangement for e.g. electrical drive of motor vehicle, has radial bearing and axial bearing that is arranged as axial bearing ring in axial opening between axial inner wall area and rotor front side area

摘要

The arrangement has a rotor (3) with a given radial opening distance to an inner wall area (11) that radially surrounds a radial-casing area (8) in a radial direction. A radial bearing (13) is arranged as a radial dry-running operation bearing in a radial opening (5) between the rotor-casing area and the inner wall area. An axial bearing is arranged as an axial bearing ring (15) in an axial opening (6) between an axial inner wall area (12) and a rotor front side area (10).
