SLIDING BEARING FOR INTERNAL COMBUSTION ENGINE

摘要

A sliding bearing being improved in resistance to seizure under a high bearing pressure condition, the bearing having a lining of a copper alloy in which Ag and Sn are preset as additive metals in solid solution state and form a hexagonal compound or an eutectic between themselves or with Cu. The improved bearing has a back metal having, adhered thereon, a copper alloy wherein 0.1 to 2 wt.% of Ag and 1 to 10 wt.% of Sn are present as essential metal components and the residue is composed essentially of Cu, and a surface obtained by covering a roughened surface, which is positioned on the opposite side to said back metal of copper alloy and has a roughness (Rz) of about 0.5 to about 10 mu m, with an overlay of a thermosetting resin, such as a polyimide resin, a polyamideimide resin, an epoxy resin and a phenol resin, containing MoS2 in an amount of 55 to 90 wt.%.
