ROLLER BEARING ASSEMBLY (VERSIONS) Russian patent published in 2012 - IPC F16C19/38 F16C19/40 F16C33/76 B61F15/22 

FIELD: machine building.

SUBSTANCE: roller bearing assembly (10) includes inner race (38, 40) with raceway facing to the outside, external race (32) with raceway (34, 36) facing to the inside and directed radially, the bore (17, 19) of which faces inwards, between raceways of which there retained are rollers (42, 44), divider (46) adjacent to inner race (38, 40), wear ring (60, 62), seal (52, 54) and support (72) of divider. Ring (60, 62) adjoins flat end of ring (38, 40), which faces inwards along the axis, and directed inwards from it in axial direction, and has cylindrical external surface (37, 60). Seal (52, 54) has the first end part (48, 50) and the second end part (55, 63). At that, the first end part (48, 50) enters bore (17, 19) of ring (32). Support (72) of divider has inner end directed radially and adjacent to divider (46), and outer end directed radially and adjacent to ring (32). According to the second version, bearing assembly (10) differs from the first one in the way that it contains elastic sealing element (56, 58) attached to part (55, 63); besides, element (55, 63) contacts surface (37, 60) of ring (60, 62).

EFFECT: providing proper distance between inner races due to clamping and positioning of divider.
