SPHERICAL PLAIN BEARING Russian patent published in 2019 - IPC F16C11/06 F16C17/00 F16C23/04 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, as well as to other industries, in which designs of friction bearings are used, in particular, can be used in machine building, in elements of friction assemblies of different machines, mechanisms and equipment. Spherical plain bearing includes inner ring (1) with external spherical surface, outer ring (2) with inner spherical surface and at least two flat resilient inserts (3) fixed in external ring. Inserts (3) are installed in equatorial plane perpendicular to axis of outer ring (2) with possibility of interaction with inner ring (1), in which annular groove (4) is made in equatorial plane perpendicular to ring axis. Groove of inner and outer ring is made equal to width of insert (3). Circular groove (4) of internal ring (1) has Y-shape in cross section and is made with expansion of section to periphery, and insert (3) is made in form of Belleville flat plate spring. Insert (3) is made in the form of Belleville flat plate spring, in Y-shaped cross-section it is made with expansion of section to center.

EFFECT: technical result is creation of spherical sliding bearing with high bearing capacity, operating under conditions of possible motions, perpendicular to bearing axis (inclinations).
