Bearing arrangement for rotatable supporting of shaft opposite to housing, has magnetic bearing and catch bearing that has roller bearing for transmitting axial or radial forces between shaft and housing

摘要

The bearing arrangement (1) has a magnetic bearing (2) and a catch bearing (5) that has a roller bearing for transmitting axial or radial forces between a shaft (4) and a housing (3',3''). The catch bearing has a slide bearing that transmits additional forces between the shaft and the housing from a predetermined load of the roller bearing. The slide bearing has a slide bearing disk (13,14) connected with a bearing ring of the roller bearing in a torque-proof manner. the slide bearing disk has an annular body with a reinforcing rib (23).
