1. The gear reducer motor overheats during the working process, and may even burn out the gear reducer motor. This scenario is usually common and usually has two factors. First, the gear reduction motor is overloaded. In this case, the user should check the rated power and actual load of the geared motor, and adjust it to a suitable gear. The second is the lack of lubricating oil, just add lubricating oil on time
2. Abnormal noise is generally divided into two categories. One is that the gear motor is working normally. In this case, it may be grinding noise. The bearing is damaged or the gear meshing is irregular. You can check the oil condition of the gear reducer in advance. If not, contact the customer in time. Service, the second is unstable working noise, relatively simple, oil pollution or lack of oil, according to the method.
3. In daily life, people may think that more oil is better, but they don't know that more oil will lead to such a scenario. Change gear oil every six months. Add oil to the gear motor oil level hole, not too much.
In the long-term operation of the gear reducer, faults such as wear and leakage often occur, mainly including:
1. The wear of the bearing chamber of the reducer, including the wear of the housing bearing box, the bearing chamber of the box hole, and the bearing chamber of the gear box.
2. The gear shaft diameter of the reducer is worn, and the main wear parts are the shaft head, keyway, etc.
3. The reducer wears the bearing position through the transmission shaft.
4. The joint surface of the reducer leaks.
For the wear problem, the traditional solution is machine maintenance after repair welding or brush plating, but both have some disadvantages: the thermal stress caused by the high temperature of repair welding cannot be completely solved, and material damage is prone to occur, but due to the limitation of coating thickness, The brush plate is easy to fall off, and the above two methods are to repair the metal with metal, which can neither change the "hard to hard" matching relationship, but also cause re-wear. Some large bearing enterprises cannot solve on-site problems and rely more on external maintenance. In order to solve the above problems, the repair method of polymer composites, which have strong adhesion and excellent compressive strength, has been widely used elsewhere. The maintenance is made of polymer materials, which does not need to be disassembled and processed, and is not affected by the thermal stress of the repaired welds, and the maintenance thickness is not limited.
For the leakage problem, the traditional method needs to disassemble and open the reducer, then replace the sealing gasket or apply sealant, which is time-consuming and laborious, and leakage will occur again during operation. The polymer composite material can control the leakage on the spot, and the material must have excellent adhesion, overcome the influence caused by the vibration of the reducer, and solve the leakage problem of the reducer well.
