内燃机车主轴承失效故障分析及控制措施研究

Research on Failure Analysis and Control Measures of Main Bearing Failure in Internal Combustion Locomotives

以某内燃机车为例,对柴油机主轴承失效情况进行统计,从机体、曲轴、轴瓦三大部件方面剖析主轴承失效的原因,并提出具体的控制措施。

Taking an internal combustion locomotive as an example,the failure of main bearing of diesel engine is statistically analysed,and the reasons for the failure of main bearing are analysed in terms of three major components,i.e.,body,crankshaft and axle shaft,and specific control measures are proposed.
