1.损坏原因 (1)变速箱第一轴与主离合器轴同心度偏差超过4毫米,致使联轴节接盘及螺栓受到一附加力,造成接盘及螺栓疲劳损坏。变速箱第一轴与主离合器轴不同心的主要原因有5:①安装调整不当;②发动机前支架和前梁磨损,发动机后支座螺栓松动,这样,工作中机车频繁震动,破坏了变速箱第一轴与主离合器轴的同心度;③车架顺梁变形、折断或铆钉松动,使发动机和后桥轴的相对位置发生变化,破坏了变速箱第一轴与主离合器轴的同心度;④修理铆合车架时,前后横梁的相对位置改变,致使发动机和后桥的相对位置改变,造成变速箱第一轴与主离合器轴不同心;⑤变速箱前支点螺栓松动或丢失,使变速箱和后桥有
1. Causes of damage (1) Concentricity deviation of the first gear shaft of the transmission with the main clutch shaft is more than 4mm, resulting in an additional force on the coupling plate and the bolt, resulting in fatigue damage of the connecting plate and the bolt. The main reason for the gearbox first axis and the main clutch shaft is not the heart of 5: ① improper installation; ② engine front bracket and front beam wear and tear, the engine rear bearing bolts loose, so that frequent vibration locomotive at work, destroyed the gearbox The first shaft and the main clutch shaft concentricity; ③ frame along the beam deformation, fracture or rivet loose, so that the relative position of the engine and the rear axle change, undermining the first gear shaft and the main clutch shaft concentricity; ④ repair riveting frame, the relative position of the beam before and after the change, resulting in changes in the relative position of the engine and the rear axle, resulting in the first gear shaft and the main clutch shaft is not the heart; ⑤ front fulcrum bolt loose or missing, Box and rear axle there
