济南装载机配件谈铰接销损坏怎么办？

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。
