Multi-layer engine bearings and method of manufacture |
摘要 |
A multilayer engine bearing (26) includes a steel backing (36) having a liner (38) of bearing metal of either copper-lead or aluminum alloys formed on the backing (36) and a thin layer (44) of either copper or nickel plated on the liner (38) to define a base lining member (40) of the bearing (26). A multilayer overplate (46) is formed on the base lining member (40) and includes an underlayer (48) of a lead-tin-copper alloy having a thickness of about 10 mum and an overlayer (50) of tin having a thickness of about 5 mum. The multilayer overplate (46) exhibits exceptional fatigue resistance under high dynamic loading conditions and retains good conformability and embedibility characteristics.
