Common faults and solutions
In long-term operation of the reducer, wear and leakage often occur. The most important ones are:
1. The bearing room of the reducer is worn, which includes the wear of the housing bearing box, the bore bearing room in the box body, and the gearbox bearing room.
2. The shaft diameter of the gear shaft of the reducer is worn. The main wear parts are the shaft head and the keyway.
3. The bearing position of the reducer transmission shaft is worn.
4. Leaking surface of reducer.
For the problem of wear and tear, the traditional solution of the company is repair welding or machining after brush plating, but both have certain disadvantages: the thermal stress caused by the high temperature of repair welding cannot be completely eliminated, which may cause material damage and cause parts to bend or break; The brush plating is limited by the thickness of the coating, and it is easy to peel off. Moreover, the above two methods use metal to repair the metal, which cannot change the "hard to hard" cooperation relationship. Under the combined effect of various forces, it will still cause wear and tear. For some large bearing companies, it is impossible to solve it on-site, and they rely on external repair. Contemporary western countries use polymer composite repair methods to address the above problems, and more applications include Mika Technology products, which have comprehensive properties such as superior adhesion and excellent compressive strength. The application of polymer material repair can be dismantled and machined without the influence of welding thermal stress, and the repair thickness is also not limited. At the same time, the metal material of the product does not have the concession, which can absorb the shock and vibration of the equipment and avoid re-wear Possibly, and greatly extend the service life of equipment components, save a lot of downtime for enterprises, and create great economic value.
For the leakage problem, the traditional method needs to disassemble and open the reducer, then replace the gasket or apply 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 material can control the 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 reducer leakage for enterprises.
