FRICTION BEARING WITH MAGNET POWDER LUBRICATING SYSTEM Russian patent published in 2010 - IPC F16C33/10 F16C32/04 F16C39/06 

FIELD: machine building.

SUBSTANCE: friction bearing with magnet powder lubricating system consists of shaft out of magnet conducting material, of diamagnetic bushing with cavities for magnet-powder lubrication and of unit for lubricant loosening. Rectilinear tapers at angle to internal surface of the bushing are made on internal surface of it on ends of each cavity from the side of the shaft; the tapers facilitate supply of magnet-powder lubricant in contact between the bushing and the shaft. The unit for lubricant loosening is made in form of a rod installed into each cavity of the bushing; one end of each of these is rigidly fixed on surface of the bushing, while ribs for lubricant loosening are secure on the free end. External surface of the shaft is equipped with a lug at shaft rotation interacting with the free end of each rod of the unit for lubricant loosening.

EFFECT: increased resource of bearing and reliability of its operation.
