선박엔진용 Supply Unit에 대한 Camshaft의 마찰특성

The wear and friction characteristics of cam shaft in power supply unit have been investigated as function of a driving loads and speeds. The cam shaft is a core part in ship engine. To improve the efficiency of the engine, we had tested the friction and wear of them. The wear of SM45C is more degraded up to compared with SNCM420 materials. Also the friction characteristics of SNCM420 is lower than SM45C in high loads.
