| 摘 要： | 针对某型柴油机连杆轴瓦多次出现异常磨损,且均为短里程异常磨损的问题,对相关零部件的设计和应用进行分析。分析表明:曲轴连杆颈油孔倒角位置圆角过小及连杆轴瓦工作表面处理方式不当是导致该故障的主要原因。据此给出了改进方案,经台架试验及市场验证,该改进方案有效。

| Abstract: | Abnormal wear of connecting rod bearings occurred several times on a certain type of diesel engines, and all within short running time. Research was carried out on the design and application of relative components. The results show that the corner at the oil hole fillet of crank pin is too small and bad surface treatment of the bearing are the main causes. The improvement measures were given and proved to be effective by bench test and market feedback. |
