HINGED BEARING AND ITS APPLICATION IN BALL-AND-SOCKET HINGE Russian patent published in 2011 - IPC F16C11/06 B60G7/02 

FIELD: machine building.

SUBSTANCE: hinged bearing (1) for ball-and-socket hinge consists of two spherical insertions (1a, 1b) of friction bearing. These insertions have sliding layer (5) containing sliding material and at least one stable by form bearing layer (7). Insertions (1a, 1b) of friction bearing additionally contain at least one flexible layer (9) arranged in insertion (1a, 1b) of the friction bearing with preliminary tension in a direction perpendicular to the direction of layer expansion. Additionally, the invention refers to the ball-and-socket hinge including ball-like head (2) of the hinge and spherical hinged bearing (1) and to preferable application of hinged bearing (1) according to the invention.

EFFECT: self-lubricating hinged bearing of simple design and with improved characteristics for vibration damping wherein there is compensated operational wear of material of sliding layer at operation of hinged bearing.
