METHOD FOR MANUFACTURE OF PLAIN BEARING Russian patent published in 2002 - IPC

FIELD: process of molding of polymeric articles by centrifugal method. SUBSTANCE: polymeric composition in the form of a binder and filler is loaded into a metal bushing, and molding of the antifriction layer is accomplished at rotation of the metal bushing during preset periods at different speeds. During molding the binder is separated from the filler due to selection of the speed of rotation of the metal bushing, and after curing of the polymeric composition the clean layer of the binder is removed by boring. The density of the obtained layer of filler is adjusted due to variation of the speed of rotation of the metal bushing. Besides, the thickness of the obtained layer of filler is adjusted due to the amount of the injected filler. In contradistinction to the analogs, the given method for manufacture of the plain bearing provides for enhancing of the article guality due to uniform distribution and increasing of the density of the filler in the zone of friction. EFFECT: enhanced reliability and durability of the friction assembly. 3 cl, 4 dwg, 2 tbl
