PROCEDURE FOR FABRICATION OF FRICTION BEARING Russian patent published in 2011 - IPC F16C33/00 

FIELD: machine building.

SUBSTANCE: according to invention there is fabricated bushing out of steel. The bushing has external diametre equal to pilot diametre of the unit, while internal diametre is bigger, than nominal. After fabrication "jugged" thread is cut on internal surface of the bushing and successively this surface is rolled at a slanted net. Bronze powder is sputtered by the gas-thermal procedure onto thus prepared surface. Upon sputtering the bearing is mechanically processed.

EFFECT: reduced cost of fabrication of friction bearing at high strength of adhesion of sputtered layer with base.
