METHOD FOR MANUFACTURE OF PLAIN BEARING Russian patent published in 2003 - IPC

FIELD: process of molding of plastic articles by the centrifugal method applicable for manufacture of plain bearings. SUBSTANCE: polymeric composition is loaded in a metal bushing in the form of a binder and fillers. Molding of antifriction coating is accomplished at rotation of the metal bushing. The fillers are loaded in the required sequence in the periods of rotation of the metal bushing providing for delamination of the fillers by layers in thickness of the antifriction coating. Use is made of different speeds of rotation of the metal bushing and conditions of cutting of the polymeric composition. The first filler of reinforcing material is loaded at a high speed of rotation of the metal bushing. The rest antifriction fillers are loaded in a pure layer of the binder after segregation of the reinforcing material at low speeds of rotation of the metal bushing. EFFECT: enhanced antifriction properties and durability of the plain bearing. 3 cl, 4 dwg
