SPHERICAL DOUBLE-ROW ROLLING BEARING Russian patent published in 2013 - IPC F16C19/49 F16C23/08 F16C33/60 

FIELD: machine building.

SUBSTANCE: spherical double-row rolling bearing includes split external (1) and internal (2) races with raceways, rolling bodies (3, 4), and cage for separation of rolling bodies (3, 4). Raceway of the first half of race (1) has toroid-shaped surface. Raceway of race (2) has spherical surface. Rolling bodies in the first half of race (1) are made in the form of rollers (3) having the profile conjugated with surfaces of raceways of races (1,2). Rolling bodies in the second half of race (1) are made in the form of balls (4) having the profile conjugated with surfaces of raceways of races (1).

EFFECT: reduction of friction losses during operation of the bearing.
