THREE-ROW SELF-ALIGNMENT RADIAL PLAIN BEARING Russian patent published in 2012 - IPC F16C19/54 F16C19/55 

FIELD: machine building.

SUBSTANCE: proposed bearing comprises iner race 1, first intermediate race 2, second intermediate race 3, outer races 4 and solids of revolution 7 arranged there between. Iner and intermediate races 1 and 2, 3, respectively, represent eccentric element while outer race 4 is concentric element. Sum of eccentricities (e₁, e₂) of iner (1) and first intermediate (2) races exceeds that of eccentricity (e₃) of second intermediate race (3) and eccentricity (e₄) between geometrical axes (O₁, O₄).

EFFECT: transfer or rotation from inner race to outer race at misaligned axes of said rings.
