SEALING SYSTEM FOR ROILING BEARING Russian patent published in 2016 - IPC F16C33/78 F16J15/32 

FIELD: machine building.

SUBSTANCE: invention relates to sealing system to seal the rolling bearing, in particular wheel bearing, between the first (30, 32) and second elements (31). Both bearing elements (30, 31, 32) are made with possibility of rotation relatively to each other, and create both axial intermediate space (61), and radial intermediate space (60) relatively to the common axis of rotation. The sealing system includes installation element (14, 24) with fastening part (37, 40) having shape of hollow cylinder to secure element (14, 24) on second element (31), and ring part (41, 43) to position the element (14, 24) on second element (31), secured on the first element (30, 32) of bearing the carrying attachment (39, 45) with elastic element (13, 23), creating the first axial sealing edge (17, 29) and/or radial sealing edge (19, 36). Element (14, 24) is provided to create the first catching groove (12, 22) with the going radially element of the second element (31). End part (34, 44) of element (14, 24) partially limits the hole (50, 51) exiting to the first catching groove (12, 22). Hole (51) is partially limited by continuation (26) of the elastic element (23).

EFFECT: increased service life and efficiency of sealing of the sealing system based on sealing edges, without loss of known properties of existing sealing systems.
