What factors need to be considered during the purchase of magnetic couplings? The magnetic coupling has the advantages of no wear, less touch, avoidance of protection, and the driving vibration is not transmitted to the output. In general, the coaxial transmission includes the following parts: outer rotor, inner rotor and barrier sleeve bearing system. Among them, the barrier sleeve and the bearing system are mainly used in the structure of the magnetic transmission seal.

       The magnetic coupling does not need to be directly mechanically connected in the working state, but uses the interaction between the rare earth permanent magnets, and the magnetic field can penetrate a certain space interval and the characteristics of material materials to transmit mechanical energy. The appearance of the magnetic coupling solves the leakage problem of the dynamic seal in some mechanical equipment. This product is widely used in sealed transmission machinery in chemical, electroplating, papermaking, pharmaceutical, food, vacuum and other industries.

       Drive, control and control output can be achieved through the transmission of rotation, so what needs to be considered in the selection of it?

       1. Magnetic couplings are partly standardized products. In the initial stage of selecting couplings, it is possible to understand whether there are any types of coupling products that meet the needs of use in my country's standards, machinery industry standards and my country's patented coupling products.

       2. The torque of the magnetic coupling should meet the requirements of the power machine of the transmission system. According to the power and speed of the power machine and the working machine, a reasonable torque value of the coupling can be calculated, so that the coupling can be selected.

       3. After the initial selection of the magnetic coupling, the size of the coupling should be determined according to the shaft diameter and the length of the shaft hole of the driving shaft and the driven shaft, and the standard of the coupling should be adjusted.

       4. When selecting a magnetic coupling, it is necessary to comprehensively consider various factors again to ensure that the size, torque, shaft diameter, and shaft hole of the coupling are matched with the prime mover and working machine, and can adapt to the working environment.
