ANTIFRICTION PRODUCT Russian patent published in 1996 - IPC

FIELD: various blanches of mechanical engineering in manufacture of products of the type of band packing rings, bearings and guide operating with friction in pairs with metal counterparts. SUBSTANCE: antifriction product has wear-resistant polymer base whose external surface from one and both sides is coated with a layer of filled antifriction polymer. In service, at the alignment stage, intensive attrition (wear) takes place of nonfilled layer 2 with formation on the metal counterpart of thin polymer antifriction film without particles of filler. In this case, alignment process is accelerated with minimum friction coefficient that contributes to higher economic efficiency of the unit as a whole. Alignment is discontinued with full wear of coating 2 from nonfilled antifriction polymer and formation on the surface of metal counterpart of thin polymer film. EFFECT: higher efficiency. 2 dwg
