摘　　要：柴油机是船舶的动力系统,其质量关系到整个船舶的性能。曲轴作为重要的核心零部件,长期以来作为国内外柴油制造厂家将曲轴作为研究的重点。曲轴作为柴油机的组成部分,表面承受很大的压力,轴颈散热能力差导致材料磨损。因此,必须进行检查,进行预防,减少事故的发生。围绕中速柴油机曲轴的磨损故障展开讨论,常见损伤有磨损、裂纹等,分析故障的处理措施,提出曲轴磨损故障的预防技术。The diesel engine is the power system of the ship,and its quality is related to the per⁃formance of the whole ship.As an important core component,the crankshaft has long been the fo⁃cus of research as a domestic and foreign diesel manufacturer.As an integral part of the diesel en⁃gine,the surface of the crankshaft is subjected to a lot of pressure,and the poor heat dissipation ability of the journal leads to material wear.Therefore,it is necessary to carry out inspections to prevent accidents and reduce the occurrence of accidents.This paper discusses the wear and tear faults of the crankshaft of medium-speed diesel engines,and the common damages include wear and cracks,analyzes the treatment measures of the faults,and proposes the prevention technology of crankshaft wear faults.
