Coupling is an important part in mechanical transmission, which transmits torque through the interconnection of the driving shaft and the driven shaft.
The traditional coupling is contact type, the structure is relatively complex, and wear will occur in daily operation. If the operation is overloaded, it will cause serious wear to other mechanical parts, which is very unfavorable to the stability of mechanical operation equipment. of. If the driving shaft and the driven shaft of the coupling need to work in two different media that are isolated from each other, sealing elements must be used for dynamic sealing. In this way, there will be either increased rotation resistance to ensure reliable sealing, or poor sealing Problems with leakage.
In addition, with the wear and aging of sealing elements, the leakage will be aggravated, especially in the system where harmful gas (hazardous liquid) exists, once it leaks, it will pollute the environment and endanger life.
The magnetic coupling is a non-contact coupling, which is generally composed of two magnets, and an isolation cover is set in the middle to separate the two magnets. The inner magnet is connected to the transmission part, and the outer magnet is effectively connected to the power part. Magnetic field NS pole coupling interaction transmits power. The magnetic coupling has the function of buffering and absorbing vibration.
In addition, it adopts a new magnetic coupling principle to realize the transmission of force and torque between the driving shaft and the driven shaft without direct contact, and can turn the dynamic seal into a static seal. , to achieve zero leakage. Therefore, it is widely used in occasions with special requirements for leakage.
