due toReducerThe operating environment is harsh, and failures such as wear and leakage often occur. The most important ones are:
1. Wear of the bearing chamber of the reducer, including the bearing housing of the housing, the bearing chamber of the housing bore, and the bearing chamber of the gearbox
2. The shaft diameter of the gear shaft of the reducer is worn, and the main wear parts are the shaft head, keyway, etc.
3. Wear of the bearing of the reducer drive shaft
4. Leakage on the joint surface of the reducer
For the wear problem, the traditional solution of the company is repair welding or machining repair after brush plating, but both have certain drawbacks: the thermal stress generated by the high temperature of repair welding cannot be completely eliminated, and it is easy to cause material damage and cause the parts to bend or break; However, electric brush plating is limited by the thickness of the coating, which is easy to peel off, and the above two methods use metal to repair the metal, which cannot change the \"hard to hard\" coordination relationship. Under the combined action of various forces, it will still cause re-wear . For some large bearing companies, it is impossible to solve them on-site, and most of them rely on outsourcing to repair. Contemporary Western countries mostly use polymer composite repair methods for the above problems, which have super adhesion, excellent compressive strength and other comprehensive properties. The application of polymer materials for repair can avoid disassembly and machining. There is no thermal stress of repair welding, and the repair thickness is not limited. At the same time, the product has the retreat of the metal material, which can absorb the shock and vibration of the equipment and avoid re-wearing Possibly, and greatly extend the service life of equipment components, save a lot of downtime for enterprises, and create huge economic value.
For the leakage problem, the traditional method needs to disassemble and open the reducer, replace the sealing gasket or apply the sealant, which is time-consuming and laborious, and it is difficult to ensure the sealing effect, and leakage will occur again during operation. The polymer material can treat leakage on site. The material has superior adhesion, oil resistance and 350% stretch, overcomes the impact of reducer vibration, and solves the problem of reducer leakage for enterprises.
