Forging Manufacturer: Troubleshooting of reducer forgings
Forging manufacturer: Due to the long-term use of reducer forgings in harsh environments, there will inevitably be wear and leakage during use, mainly caused by the wear of the bearing type of the reducer forging, including the wear of the shaft program shell inside the box, the wear of the bearing box and the wear of the bearing type of the gearbox, while the gear shaft diameter of the reducer is mainly worn at its shaft head and keyway. The rotating bearing position of the gearbox may wear and the bonding surface may leak. Next, Bian Xiao will share with you how we should deal with these gearbox forging failures.
Forging manufacturer: For the wear of reducer broken arrows, we can repair them by patch welding or electric brushing plating. However, these two methods also have some disadvantages, that is, the heat stress generated by the high temperature when patch welding can not be completely eliminated, easy to damage the reducer forging, resulting in parts fracture or bending. However, due to the limitation of the thickness of the coating, the brush degree is easy to fall off. And the above two methods are used to repair the metal, can not change the form of hard-to-hard matching. Under the action of various forces, it is likely that the state of wear will appear again. But for some large bearing parts, there is no immediate solution. In many cases, they are repaired by external equipment.
Forging manufacturers: Later on, people used the repair method of polymer composites, which have high adhesion and good compressive strength. If the reducer is repaired with polymer materials, it is avoided that the machine can be dismantled without machining and that it does not need to be patched under the influence of thermal stress. At the same time, the thickness of the repair is not limited. At the same time the retreat of the product metal material absorbs the shocks and vibrations of the reducer forging in the working process, thus preventing the reducer forging from wearing out again.
Forging manufacturer: To solve the leakage problem, the traditional method requires disassembling and opening the reducer forging, then replacing the sealing gasket or applying sealant, which is not only time-consuming and laborious, but also difficult to ensure the sealing effect, and the leakage will occur again during operation. Polymers can handle leaks on site, and the material has good adhesion, oil resistance and 350% elongation, which overcomes the effects of reducer vibration and solves the problem of reducer forging leaks very well. One of the main causes of oil leakage from reduction gear forgings is that the internal pressure is higher than the external atmospheric pressure. If we manage to balance the internal and external pressures in the engine, we can prevent the well cover from being opened each time we refuel. If we open it once, we increase the likelihood of an oil leak so that the original leak will also occur.
