    由于作业时装载机上下两铰接销要承受很大的径向冲击载荷,其装配轴承的配合间隙很容易变大、极易磨损毁坏,若按常规维修思路修复装载机,则修理难度大、费用高,并且影响机架的整体性能,为保证机架可靠的工作要求,济南装载机配件建议采用下列修复方法。

    1、加工一根800mm长的定位芯轴,外径尺寸与铰接销的外径一致,直线度不大于0.1mm;
    Processing a 800mm long positioning mandrel outer diameter size is consistent with the hinge pin, straightness is not greater than 0.1mm;
    2、加工4个外径Φ200mm、内径与前小型装载机机架1母孔的理论尺寸一致、厚度15mm的同心圆盘,材料用40Cr,直行渗碳处理后硬度达HRC60;
    Processing four outer diameter Φ200mm, consistent with the previous theoretical size of the inner diameter of the rack a small loader mother hole concentric plate of 15mm thickness, material 40Cr, straight carburizing HRC60 hardness after treatment;
    3、从市场上购置(或按要求加工)两根加长的铰接销,其长度约280mm;
    Purchase (or on demand processing) two elongated hinge pin, its length is about 280mm from the market;
    4、更换后机架2母孔的中间衬套;将定位芯轴1、同心圆盘2及前、后机架按图2所示位置装配,将4个圆盘分别焊在前机架板体5上,去掉定位芯轴,将同心圆盘体与前机架板体焊牢。
    Replace the intermediate frame 2 female bush hole; positioning a mandrel, the disc 2 and concentric front and rear rack assembly according to the position shown in Figure 2, are welded to the disc4 the front frame plate 5 on, remove the positioning mandrel, the concentric coil body and front frame plate weld.
    5、将加长的铰接销按图1所示位置安装即可。
