Sealing arrangement for sealing rolling bearing, of viscous coupling i.e. motor fan, has elastomeric sealing structure whose side comprises rejection structures that are arranged along opposite side of fluid flow along radial direction

摘要

The arrangement (40) has an elastomeric sealing structure (41) attached to an axial end region of a bearing such that the elastomeric sealing structure is placed relative to an abrasive movable rubbing sealing edge (46). The elastomeric sealing structure faces away from outer side of the bearing. A freely accessible side (47) of the elastomeric sealing structure comprises rejection structures (48, 49) that are arranged along opposite side of fluid flow along radial direction, where the fluid flow is extended from the rubbing sealing edge to avoid penetration of the fluid in the bearing. The fluid is specified as silicone oil.
