<P>PROBLEM TO BE SOLVED: To provide a multi-layered bearing, a thrust multi-layered bearing, and a thrust multi-layered bearing device, which are free from degradation of a friction resistance under a high speed condition, while considering an environmental conservation, and are excellent in a creep resistance, a low friction, a wear resistance, etc. under a high surface pressure. <P>SOLUTION: The multi-layered bearing 1 has a triple-layerd structure provided with: a copper sintered layer 3 including no lead on the surface of a metal iron sheet 2 constituted of a back metal; and a resin layer 4 constituted of a resin component, and formed on the copper sintered layer 3. The resin composition includes at least one filling material selected from: heat resistance synthetic resin such as polyether ether ketone resin, and polyphenylene sulfide resin; a fibrous reinforcing material such as a glass fiber and a carbon fiber; and mica and talc. The resin layer 4 is formed to coat the sintered layer 3 by spraying, on the copper sintered layer 3, heating and pressurizing a powder mixture including powder of the heat resistance synthetic resin, the fibrous reinforcing material and the filling material. <P>COPYRIGHT: (C)2013,JPO&INPIT |
