In the long-term operation of the reducer
, there are often faults such as wear and leakage. The most important ones are:
1. The bearing chamber of the reducer is worn,including the wear of the bearing housing of the shell an so on.
2. The shaft diameter of the gear shaft of the reducer is worn, and the main wear parts are in the shaft head and keyway.
3. The bearing of the reducer drive shaft is worn.
4. The reducer joint surface leaks.
For the wear problem, the traditional solution is repairing after repair welding or brush plating, but both have certain drawbacks: the thermal stress generated by the repair welding high temperature cannot be completely eliminated, which may cause damage to the material and cause the parts to bend or break. Brush plating is limited by the thickness of the coating and is easily peeled off.
For the leakage problem, the traditional method needs to disassemble and open the reducer, replace the sealing gasket or apply the sealant, which is not only time-consuming and laborious, but also difficult to ensure the sealing effect, and leakage will occur again during operation. The polymer material can be used to treat leakage on the spot. The material has excellent adhesion, oil resistance and good tensile strength, which can overcome the impact of the vibration of the reducer.
