BALL-ROLLING BEARING Russian patent published in 2019 - IPC F16C19/18 F16C33/58 

FIELD: machine building.

SUBSTANCE: invention relates to the field of engineering, in particular to multi-row anti-friction ball bearings, and can be used in low-speed high-loaded mechanisms to perceive considerable radial and axial loads, especially at considerable excess of axial load in one direction of axial load in other direction. Rolling bearing contains external split (1) and internal (4) rings with pair of raceways (5) and collars on each rolling bodies in the form of balls (6). Larger of collars (8) of outer ring (1) are located on the side of its outer ends, and smaller (9) of beads of outer ring (1), made with chamfers, are located on internal adjacent ends in section area. Larger collar (10) of inner ring (4) is located between raceways, and smaller (11) of collars of inner ring (4) are located on the side of its external ends. Outer ring (1) and inner ring (4) are made with formation of additional raceways (3, 5) on section nearby external ring (1) cutting zone. Larger of collars (7) of external ring (1), the height of which is equal to the height of collars (8) of external ring, located on the side of its external ends, is arranged on section between two raceways (2). Second larger collar (10) of inner ring (4) is located in the section between two raceways (5) opposite to the zone of external ring (1), and the smaller of collars (9) of the outer ring are made with chamfers.

EFFECT: higher bearing capacity in radial and one-sided axial directions.
