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.
