BALL SPHERICAL DOUBLE-ROW ROLLING BEARING Russian patent published in 2011 - IPC F16C19/08 F16C23/08 F16C33/58 F16C33/60 

FIELD: machine building.

SUBSTANCE: invention refers to machine building, particularly, to rolling bearings. Ball spherical double-row rolling bearing consists of external (1) and internal (2) rings with rolled races, rolling members in form of balls (3) and of a separator for separation of rolling members. Also, rolled races of external ring (1), split along symmetry axis, are made with toroid surfaces; a rolled race of internal ring (2) is spherical, while balls (3) have profile conjugated with toroid surfaces of rolled races of external ring (1).

EFFECT: increase of allowed angle of mutual distortion of rings at maintaining normal operation of bearing in whole.
