Troubleshooting
In the long-term operation of the reducer, there are often faults such as wear and leakage.Top 10 gearbox manufacturers in india The most important ones are:
1. The bearing chamber of the reducer is worn, which in turn includes the wear of the bearing housing of the housing, the bearing chamber of the housing, and the bearing chamber of the transmission.
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 position of the reducer drive shaft is worn.
4. The reducer joint surface leaks.

For the wear problem, the traditional solution of the enterprise 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; Top 10 gearbox manufacturers in india. Brush plating is limited by the thickness of the coating, and it is easy to peel off. The above two methods use metal to repair the metal, which can not change the "hard to hard" coordination relationship. Under the combined action of each force, it will still cause re-wear. For some large bearing enterprises, it is impossible to solve on-site, and it is necessary to rely on external repair. In the contemporary Western countries, the repair method of polymer composite materials is often used for the above problems, and the application has more comprehensive properties such as superior adhesion and excellent compressive strength. The application of polymer material repair can be free of disassembly and machining without the influence of repair welding thermal stress, and the thickness of repair can not be restricted. At the same time, the metal material of the product does not have the concession, which can absorb the shock vibration of the equipment and avoid the wear again. It is possible, and greatly extends the service life of equipment components, saving a lot of downtime for the enterprise and creating 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 not only time-consuming and laborious, but also difficult to ensure the sealing effect, and leakage will occur again during operation. Top 10 gearbox manufacturers in india. The polymer material can be used to treat leakage on site. The material has excellent adhesion, oil resistance and 350% elongation, which overcomes the impact caused by the vibration of the reducer, and solves the problem of leakage of the reducer for the enterprise.
