The reducer is an independent component consisting of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the original moving part and the working machine.During the long-term operation of the reducer, there will be abnormal vibration and noise. Let's take a look at the specific reasons below.
The reason for the abnormal sound may be that the bearing seat is worn, the gap becomes larger, and the abnormal sound occurs.The gears are worn, the meshing gap becomes larger, and abnormal noise is generated.Lack of lubricating oil, dry grinding sound.reducerThe shaft is bent and deformed, and abnormal noise occurs; the load is too large, and abnormal noise occurs.An important factor for shaft wear is the properties of the metal used to manufacture the shaft. Although the metal has good hardness, it has poor impact resistance and cannot be restored after deformation.And the fatigue resistance is poor, so it is easy to cause fatigue wear such as bearing chamber wear, shaft head wear, journal wear, and shaft sleeve wear of the equipment. Most of the shaft wear is not easy to be found. When people notice it, it is often already It causes the beating range of the machine to increase or the noise to increase, and in severe cases, it will also cause the machine to stop.
How to deal with the abnormal vibration of the reducer?
The common solution for enterprises is repair welding or machining repair after brush plating, but both of them have certain disadvantages: the thermal stress generated by the high temperature of repair welding cannot be completely eliminated, and it is easy to cause material damage, resulting in bending or breaking of parts; while brush plating Limited by the thickness of the coating, it is easy to peel off, and 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 equipment, it is impossible to solve it on site, and most of them have to rely on outsourced repairs.Now widely used Soleil carbon nano-polymer material technology has super strong adhesion, excellent compressive strength and other comprehensive properties.The application of this material can be repaired without disassembly and machining. There is no thermal stress of repair welding, and the thickness of the repair is not limited. At the same time, the metal material of the product does not have the concession, which can absorb the shock and vibration of the equipment and avoid the possibility of re-wear , and greatly prolong the service life of equipment components.
