摘要
东风7B型机车运用中柴油机主轴承螺栓断裂故障时有发生 ,分析认为主要有 3方面原因 :①螺栓本身的原因 ;②组装过程中产生和遗留的问题 ;③柴油机其他方面的状态对主轴承螺栓产生的影响。对主轴承螺栓的结构进行了改进。
The main bearing bolts of diesel engines of DF 7B locomotives often break during operation. There are three main reasons: (1) bolts themselves; (2) the problems occurring and left over during assembly; (3) the influences of the conditions of diesel engines in terms of the other aspects on main bearing bolts. The structure of main bearing bolts is improved.
