Rolling bearing with flexible plastics outside race - has enclosing sleeve formed with concentric zones of different elasticity

摘要

The radial rolling bearing has an outside race enclosed by a rubber or plastics sleeve. The flexible material is readily incorporated into a bearing race. The enclosing sleeve (5) is an integral component with concentric zones of different elasticity. The outside bearing face (3) is connected to an outer zone (6) of higher strength or hardness with lower elasticity than the radial outwards adjoining zone (7). The sleeve (5) is made of different injection moulded plastics materials whose contact faces are firmly joined by fusion in a hot plastics state. The outer zone of the injection moulded plastics can also be foamed.
