针对东风4型机车传动轴连续断裂故障,对变速箱的安装调整工艺进行分析,指出故障原因是安装调整变速箱时忽略了变速箱输入轴与柴油机轴中心线的平行度。通过制作并应用变速箱安装调整工具,解决了传动轴连续断裂问题。
Aiming at the continuous failure of the transmission shaft of DF4 locomotive, the installation and adjustment process of the gearbox is analyzed. The reason of the failure is that the parallelism of the input axis of the gearbox and the center line of the diesel engine is ignored when the gearbox is adjusted. Through the production and application of gearbox installation and adjustment tools to solve the problem of continuous transmission shaft fracture.
