Planetary gearbox for the wear problem, the traditional solution of the enterprise is repair welding or brush plating after machining repair, but both have certain drawbacks: the thermal stress caused by the high temperature of repair welding cannot be eliminated, which is easy to cause material damage, and the planetary gearbox causes bending or fracture of components; However, brush plating is limited by the thickness of the coating, which is easy to peel off, and the above two methods are to repair metal with metal, which cannot change the "hard to hard" fit relationship, and will still cause re-wear under the comprehensive action of various forces. For some large bearing enterprises, it is impossible to solve it on the spot, and it is mostly dependent on outsourcing repair.
In view of the above problems, the repair method of polymer composite materials is mostly used in the contemporary West, and it has super adhesion, excellent compressive strength and other comprehensive properties. The application of polymer material repair, can be disassembled and machined without the influence of thermal stress of repair welding, repair thickness is not limited, at the same time, the product has the metal material does not have the concession, can absorb the impact and vibration of the equipment, avoid the possibility of wear again, and greatly extend the service life of the equipment components, save a lot of downtime for the enterprise, and create huge economic value. In view of the leakage problem, the traditional method requires disassembling and opening the reducer, 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 will occur again during operation. Polymer materials can be treated for leakage on site, and the material has superior adhesion, oil resistance and 350% elongation, which overcomes the impact of reducer vibration and solves the problem of reducer leakage for enterprises.
