据机务段反映,东风4型内燃机车柴油机定位后,往往出现静压变速箱中心线对柴油机中心线的左右偏移较大;花键套与密封套筒内孔的四周间隙≥1.5毫米不易保证,甚至产生花键套偏磨;柴油机安装高度不易掌握等现象。总结两年多时间以来我厂检修东风4型内燃机车的经验,提出了影响柴油机安装的一些因素,供有关单位参考。 16V240Z型柴油机在机车上定位后,所处的空间位置(指曲轴中心线位置),理论上应该是水平的,与启动变速箱和静压变速箱
According to the locomotive depot, after DF4 diesel locomotive locates, there often appears left and right deviation of the center line of the static pressure transmission to the center line of the diesel engine. The clearance between the spline sleeve and the inner circumference of the sealing sleeve is not easy to be guaranteed , And even spline sleeve partial wear; diesel installation height is not easy to grasp and so on. Summary of more than two years since I plant maintenance experience Dongfeng 4 diesel locomotive, put forward some factors affecting the installation of diesel engines for reference by the relevant units. 16V240Z diesel locomotive location, the location of the space (referring to the crankshaft centerline position), in theory, should be level, with the start gearbox and static pressure gearbox
