BALL SPHERICAL DOUBLE-ROW ROLLING BEARING Russian patent published in 2015 - IPC F16C19/18 F16C33/58 

FIELD: machine building.

SUBSTANCE: bearing contains rolling bodies in form of balls (3), outer race (1) with spherical raceway connected with ball (3) surfaces, and internal race (2) with two toroidal raceways connected with ball (3) surfaces. Distance between the raceways is selected such that balls (3) of one raceway are in contact with balls (3) of adjacent raceways only creating clearance between balls (3) on the same raceway. At that the lock ring (4) is installed on one end of the outer race (1) limiting the mutual skewness of races (1, 2) and eliminating possibility of the bearing self-disassembling.

EFFECT: increased loading capacity and decreasing of bearing dimensions in longitudinal direction upon absence of the possibility for self-disassembling.
