In response to the wear problem, the traditional solution is to repair by welding or brush plating and then machine processing, but both have certain drawbacks: the heat stress generated by welding cannot be completely eliminated, which can easily cause material damage, leading to bending or fracture of the components.
while brush plating is limited by the thickness of the coating, it is easy to peel off. Both of these methods involve repairing metal with metal, and cannot change the "hard to hard" mating relationship. Under the comprehensive action of various forces, it will still cause wear and tear again. It is impossible to solve some large bearings on site.
As for the leakage problem, the traditional method requires disassembling and opening the gear reducer, replacing the sealing gasket or applying sealant, which is not only time-consuming and laborious, but also difficult to ensure the sealing effect, and leakage will occur again during operation. Meijiahua polymer materials can handle leakage on site, and the material has excellent adhesion, oil resistance, and 350% elongation, overcoming the impact of gear reducer vibration, and effectively solving the problem of gear reducer leakage for enterprises.
During long-term operation, gear reducers often experience faults such as wear and leakage, the main ones being:
1. Wear of the gear reducer bearing chamber, including the wear of the housing bearing box, the internal hole bearing chamber of the box, and the wear of the gearbox bearing chamber
2. Wear of the gear reducer gear shaft, with the main wear occurring at the shaft head, keyway, etc.
3. Wear of the gear reducer transmission shaft bearing position
4. Leakage of the gear reducer joint surface
