Due to the harsh operating environment of the reducer, there are often wear, leakage and other failures

1. The wear of the bearing chamber of the reducer includes the wear of the bearing box of the housing, the bearing chamber of the inner hole of the housing and the bearing chamber of the gearbox;
2. The main wear parts are shaft head and keyway;
3. The bearing position of transmission shaft of reducer is worn;
4. Leakage at the joint surface of reducer;
5. Did not replace the ventilation cap, as a manufacturer, especially for this point abhorrent;

In view of the wear problem, the traditional solution is repair welding or machining after brush plating, but both of them have some disadvantages: the thermal stress caused by high temperature of repair welding can not be completely eliminated, which is easy to cause material damage and lead to bending or fracture of parts; However, due to the limitation of coating thickness, brush plating is easy to peel off, and the above two methods use metal to repair metal, which can not change the "hard to hard" matching relationship. Under the combined action of various forces, it will still cause re wear. For some large bearing enterprises, it is impossible to solve the problem on site, so they have to rely on outsourcing repair. In order to solve the above problems, modern western countries often use polymer composite repair methods, which has super adhesion, excellent compressive strength and other comprehensive properties. The application of polymer material repair can avoid disassembly and machining, without the influence of repair welding thermal stress, and the repair thickness is not limited. At the same time, the metal material of the product does not have the concession, which can absorb the impact and vibration of the equipment, avoid the possibility of re wear, greatly extend the service life of the equipment parts, and save a lot of downtime for the enterprise, Create huge economic value.

To solve the leakage problem, the traditional method needs to replace the sealing gasket or apply sealant after disassembling and opening the reducer, which is not only time-consuming and laborious, but also difficult to ensure the sealing effect, and leakage will occur again in operation. Polymer materials can be used to control the leakage on site. The excellent adhesion, oil resistance and 350% tensile strength of the materials can overcome the influence caused by the vibration of the reducer and solve the leakage problem of the reducer for the enterprise.

Because there are so many types, specifications and parameters of reducers, many people in the industry do not know how to choose the correct type, so it is normal for the user to have problems in the selection of reducers, which leads to the damage or short service life of reducers; There is also a very important problem. In order to reduce the cost, some equipment manufacturers and users choose one or two smaller models of reducers. If the models of reducers are smaller, the price will come down. This is one of the main reasons why reducers often have problems.
