After using the mining electric locomotive for a period of time, sometimes abnormal noise can be heard from the reduction box. What are the reasons for this phenomenon? Here are a few reasons we have sorted out for you:
1. Need to add lubricating oil.
2. The load is too large or the speed is too high, and the pressure of the gearbox parts is too high.
3. The gear needs to be replaced, if the tooth surface is severely worn or broken, so that the meshing is not good.
4. The bearing needs to be replaced, ibid.
5. The fasteners on the gearbox are loose.
After abnormal noise is found, the cause should be found out in time and the corresponding treatment should be carried out.
