What Are The Common Failure Analysis And Treatment Methods Of The Reducer?
The reducer manufacturer’s friendly reminder:
The operating environment of the reducer needs to be clean and tidy. Due to the poor operating environment of some customers, the reducer often suffers from wear and leakage.
To summarize, the main faults include the following:
Fault 1: The shaft diameter of the gear shaft of the reducer is worn, and the main wear parts are on the shaft head, keyway, etc.;
Fault 2: wear of the bearing chamber of the reducer, including the wear of the housing bearing box, the bearing chamber of the box bore, and the bearing chamber of the gearbox;
Fault 3: Leakage on the joint surface of the reducer;
Fault 4: The bearing of the reducer drive shaft is worn out.
The processing methods given for the above faults:
For the wear problem, the traditional solution is repair welding or machining and 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 parts to bend or break; and Electric brush plating is limited by the thickness of the coating and is easy to peel off. 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 cannot be solved on-site, and most of them have to rely on outsourcing to repair.
For the leakage problem, the traditional method needs to disassemble and open the reducer, replace the sealing gasket or apply 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.
In view of the above problems, the repair methods of polymer composite materials are often used, and the comprehensive properties such as excellent compressive strength are used. The application of polymer materials for repair can avoid disassembly and machining. There is no thermal stress for repair welding, and the repair thickness is not limited. At the same time, the product has a retreat that the metal material does not have, 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.
