摘　　要：为进一步预防因船用柴油机凸轮轴故障造成的问题,文章以船用中速柴油机凸轮轴故障原因及分析为研究方向。选取装船机器是12v280系列柴油机为例。从案例分析来看,常见故障为凸轮啃伤、凸轮型面剥离、硬质拉伤、凸轮型面异常磨损、衬套(轴承)烧损等,针对上述问题,文章提出相关针对性措施,在凸轮啃伤预防措施上,应保证导向销装配过盈、提高导向销耐磨性能同时,防止喷油泵工作负荷失衡,同时做好凸轮型面剥离预防,减少凸轮轴型面磨损及预防衬套(轴承)烧损。In order to further prevent the problems caused by the camshaft failure of Marine diesel engine camshaft,the reason and analysis of the camshaft failure of Marine diesel engine are the research direction.The loading machine is selected to be a 12v280 series diesel engine as an example.From the case analysis,common faults for cam bite,cam face stripping,hard strain,cam surface abnormal wear,bushing(bearing)burn,etc.,according to the above problems,the paper puts forward the relevant targeted measures,prevention measures,on the cam should ensure the guide pin assembly surplus,improve the guide pin wear resistance performance at the same time,prevent the injection pump load imbalance,and cam surface wear and prevention of liner(bearing)burn,in order to provide theoretical guidance and help for relevant scholars.
