Due to the harsh operating environment of the gearbox, wear and leakage often occur. The editor of Shangying Transmission Technology will take you to learn about the troubleshooting methods of the gearbox, hoping to be helpful to you.
The fault classification is:
1. The wear of the gearbox bearing chamber includes the wear of the housing bearing box, the inner hole bearing chamber of the housing, and the gearbox bearing chamber;
2. The gear shaft diameter of the reducer is worn, mainly on the shaft head, keyway, etc;
3. The bearing position of the gearbox transmission shaft is worn;
4. The joint surface of the reducer is leaking.
The traditional solution to the problem of wear and tear is to repair it by welding or machining after brushing, but both have certain drawbacks: the thermal stress generated by high temperature welding cannot be completely solved, which can easily cause material damage and lead to bending or fracture of components; However, electric brush plating is limited by the thickness of the coating and is prone to peeling off. Both methods use metal to repair the metal and cannot change the "hard to hard" fit relationship. Under the combined action of various forces, it will still cause further wear. For some large bearing enterprises, it is even more difficult to solve on site, and they rely heavily on outsourcing repairs.
Contemporary Western countries often use polymer composite materials as repair methods for the above problems, which have good adhesion, excellent compressive strength and other comprehensive properties. The application of polymer materials for repair can be done without disassembly or machining, without the influence of welding thermal stress, and the repair thickness is not limited. At the same time, the product has the flexibility that metal materials do not have, which can absorb the impact and vibration of equipment, avoid the possibility of further wear, and greatly extend the service life of equipment components, saving a lot of downtime for enterprises and creating huge economic value.
For the leakage problem, traditional methods require disassembling and opening the gearbox, replacing the sealing gasket or applying sealant, which is not only time-consuming and laborious, but also difficult to ensure the sealing effect, and leakage may occur again during operation. Polymer materials can be used for on-site leakage control. The superior adhesion, oil resistance, and 350% tensile strength of the material overcome the impact of gearbox vibration and effectively solve the problem of gearbox leakage for enterprises.
