链式拖拉机修理费多是我团农机维修的一个实际问题。平均在1.7万元左右,个别机车修理费高达2.5万元以上。有的机车修后技术状态并没有恢复,表现在:①变速箱第一轴与离合器轴同心度超差,车架变形松动,方向接盘经常损坏,408轴和50408轴承超耗,发动机震动,更有甚者驾驶棚晃动,各紧固件松动。②链轨板脱轨,引起前梁断裂,引导轮拐轴变形,后桥空心轴弯曲,由于多次脱轨,加剧了以上各件的损坏。③后桥空心大轴在车架上不易紧固,紧固后又松动。更有甚者,拖拉机—带负荷变速箱前端抬头,
Chain tractor repair fee is more than a problem of maintenance of our farm machinery. An average of 17,000 yuan, individual locomotive repair costs up to 25,000 yuan or more. Some locomotive repair after the technical state and did not recover, manifested in: ① first gear shaft and clutch shaft concentricity over poor, loose frame deformation, the direction of the plate is often damaged, 408 and 50408 bearing overload, engine vibration, more Some even swinging shed, the fasteners loose. ② derailment of the chain rail plate, causing the front beam fracture, the guide wheel camshaft deformation, bending the hollow shaft after the bridge, due to repeated derailment, exacerbated the above pieces of damage. ③ rear axle hollow shaft in the frame is not easy to fasten, loose after fastening. What is more, tractors - with load transmission front-end rise,
