Title:
高強度を示しかつ高温環境下ですぐれた耐摩耗性を示すEGR式内燃機関の再循環排ガス流量制御弁用焼結Cu合金製軸受
Document Type and Number:
Japanese Patent JP4507766
Kind Code:
B2
Abstract:
To provide a bearing made of a sintered Cu alloy for a recirculation exhaust gas flow rate control valve of an EGR type internal combustion engine, which has a high strength and exhibits excellent abrasion resistance even under a high temperature environment. The bearing for a reciprocating shaft made of an austenitic stainless steel operating the recirculation exhaust gas flow rate control valve of the EGR type internal combustion engine is made of sintered Cu alloy with a composition consisting of, by mass %, Ni: 10 to 30%, Sn: 5 to 12%, C: 3 to 10%, P: 0.1 to 0.9%, and Cu and inevitable impurities as the balance, and having a structure in which free graphite is dispersed and distributed into the base of a Cu-Ni-Sn-P based solid solution.
