MAGNETIC BEARING Russian patent published in 2020 - IPC F16C32/04 F16C39/06 

FIELD: machine building.

SUBSTANCE: invention relates to magnetic bearings on permanent magnets, which can serve as support for rotating shafts of machines and mechanisms. Unlike common sliding and rolling bearings, the connection in the declared magnetic bearing with the shaft is mechanically noncontact, i.e. principle of magnetic levitation is used. Magnetic bearing is made in the form of two solid rotation bodies (1, 2) equipped with magnetic systems (3, 4) from permanent magnets and arranged relative to each other so that their magnetic systems interact with each other through gap (5). Magnetic systems (3, 4) of volumetric bodies (1, 2) are made so that surfaces of magnetic systems (3, 4) in the place of their interaction through gap (5) have identical magnetic poles and are made with shapes providing gap equidistance (5) between them, wherein this surface on one solid body (1) is made convex, and interacting with it surface on other solid body (2) is concave, besides, one of the magnetic systems is designed so that the line of equal potential of its magnetic field in cross section is a continuous line, and the similar pole of magnetic system (3, 4) interacting with it is placed in the zone of its magnetic field action.

EFFECT: providing stable interaction and non-contact arrangement of permanent magnets of two magnetic systems of magnetic bearing in space relative to each other at axial loads with provision of stability of volume bodies in axial and radial direction.
