ANTI-FRICTION BALL BEARING Russian patent published in 2018 - 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-turnover, high-loaded mechanisms to perceive significant radial and axial loads. Ball bearing has outer ring (1) and internal split ring (4) with raceways (2, 3, 5, 6) and collars on each of them, rolling bodies in the form of balls (7). Larger (12) collars of inner ring (4) are located on its outer ends, and smaller (13) collars of inner ring, made with bevels, are located on the inner adjacent ends of its halves. On each ring (1, 4) two pairs of aligned raceways are made (2, 3, 5, 6). Larger (9) collar of outer ring (1) is located between raceways (2, 3, 5, 6) on the axis of symmetry of the bearing. Smaller (10) collar of outer ring (1) with the bevels are located on its outer ends. Middle-height (11, 14) collars of rings (1, 4) are located between raceways (2, 3, 5, 6) inside each pair. Radial dimensions of raceways (2, 5) located at the outer ends of the bearing are larger than the radial dimensions of raceways (3, 6) located in the central part of the bearing. Difference between the diametrical dimensions of raceways (2, 3, 5, 6) along the rows of rolling elements (7) of the bearing is determined taking into account the necessary angle of contact between rolling elements (7) and raceways (2, 3, 5, 6).

EFFECT: increase bearing capacity in the axial and radial directions.
