BALL HINGE Russian patent published in 2018 - IPC F16C11/06 

FIELD: machine building.

SUBSTANCE: invention relates to a hinge support, in particular for a ball joint with a bearing of a sliding bearing. Said ball joint comprises a body in which a finger with a ball head is installed, an insert consisting of two parts made in the form of a truncated spherical shell made of elastoplastic material. Above insert has radial apertures made uniformly along the circumference in the supporting surface at the end of the truncated portion of the equatorial plane for lubrication, and further comprises a gasket of elastic material in the form of a segment of a spherical shell with a flange and radial holes positioned coaxially with the apertures of the insert and filled with a lubricant. On its top, the liner with the gasket is closed with an adjustable cap with a thread and a wrench head.

EFFECT: technical result: the creation of a self-lubricating hinged support, which is characterized by simplicity of construction and improved characteristics with respect to vibration damping, at the same time the operational wear of the slip layer material is compensated for the operation of the hinge support.
