1、装载机减速器的输入端旋转而输出端不旋转，或旋转速度明显低于正常值这种情况主要原因是，减速器的内部传动部件出了问题，多为齿轮断齿或断轴，此故障只能通过拆检减速器更换相应零件解决。
The input end of the loader reducer in Shandong is not rotated, or the rotation speed is obviously lower than the normal value. The main reason is that the internal transmission parts of the reducer are a problem, and more than a broken teeth or broken shaft, this fault can only be resolved through the replacement of the corresponding parts of the reducer.

2、装载机减速器的输入、输出端都不能旋转这种情况的检修办法有两种：一是将输入端的马达或电机反转观察是否可行，酌情修理或更换，二是拆检减速器更换相应的零件。
Shandong loader reducer input, output can not rotate the maintenance approach has two kinds: one is to the input side of the motor or motor reverse observation is feasible, as appropriate, repair or replacement, the replacement of the two is the replacement of the corresponding parts.

3、装载机减速器噪声和振动明显高于正常值造成的原因可能是，连接螺栓松动或减速器的有效定位失效，或润滑油油温太高、油液太脏。
Shandong loader gear box noise and vibration was significantly higher than that of the normal value of the cause may be, effective positioning connecting bolt looseness or reducer failure, or lubricating oil temperature is too high, oil too dirty.
