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 split (1) and inner (4) rings with two pairs of raceways (2, 3, 5, 6) and beads on each, rolling bodies in the form of balls (7). Large (9) of outer ring collars (1) are located on the side of its outer ends, and smaller (10) of outer ring beads (1) formed with the bevels are located on the inner adjacent ends of its halves. Larger (12) of the collars of inner ring (4) is centrally located, and smaller (14) of the collars of inner ring (4) are located on the side of its outer ends. Middle (11, 13) rings of rings (1, 4) are also located between raceways (2, 3, 5, 6), and smaller (14) of the beads of inner ring (4) are formed with bevels. Radial dimensions of raceways (3, 6) located in the central part of the bearing are greater than the radial dimensions of raceways (2, 5) located at the outer ends 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.
