What are the common faults of the reducer that need attention

Unlike home appliances and some standard products, the reducer is basically free of problems. On the contrary, there are often many problems, and some even break down after a few uses. There are many reasons for this. Let me tell you a few points;
Due to the harsh operating environment of the reducer, failures such as wear and leakage often occur. The most important ones are:
1. Wear of the bearing chamber of the reducer, including the wear of the housing bearing box, the inner bore bearing chamber of the box, and the gearbox bearing chamber;
2. The shaft diameter of the gear shaft of the reducer is worn, and the main wear parts are on the shaft head, keyway, etc.;
3. The bearing position of the drive shaft of the reducer is worn;
4. The joint surface of the reducer is leaking;
5. The ventilation cap was not replaced, which is especially disgusting as a manufacturer;
For the wear problem, the traditional solution is to repair welding or brush plating, but both have certain drawbacks: the thermal stress generated by the high temperature of repair welding cannot be completely eliminated, which is easy to cause material damage, resulting in bending or breaking of parts; 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" matching relationship, and will still cause re-wear under the combined effect of various forces.For some large bearing companies, it is impossible to solve on-site, and more rely on external repair.Contemporary western countries mostly use the repair method of polymer composite materials to solve the above problems, which has comprehensive properties such as super adhesion and excellent compressive strength.It is repaired by polymer materials, which can be disassembled and free of machining. It is not affected by the thermal stress of repair welding, and the repair thickness is not limited. At the same time, the metal material of the product does not have the concessional property, which can absorb the shock and vibration of the equipment and avoid re-wear. It is possible to 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, then replace the sealing 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.The polymer material can control leakage on site. The material has superior adhesion, oil resistance and 350% elongation, which overcomes the influence of the vibration of the reducer and solves the leakage problem of the reducer for the enterprise.
Since there are many types, specifications and parameters of the reducer, many people in the industry do not know how to select the correct type, so it is normal for the user to select the type and cause the reducer to be damaged or have a short service life; There is also a very important problem. In order to reduce costs, some equipment manufacturers and manufacturers choose the model of the reducer to be one or two sizes smaller. The price of the reducer will come down when the model is smaller. This is also the reducer. Often a major cause of problems.
