These kind of magnetic couplings are sticking some pieces of permanent magnet materials on the main coupling and sub-coupling. The magnet materials in the main coupling and sub-coupling shells are attracting each other, to drive two couplings attracting, then achieve the purpose of torque transmission. As the magnets have the gap, the absorbing power of non-contact magnetic coupling will decline; now, the transmission will decline too.
In addition, the cupboard is made of non-magnetic materials, or the cupboard will play a role to separate magnet so that the couple can not pass. There are two kinds of functions of magnetic couplings:
1, as the magnetic field lines loop, the magnetic couplings will reduce magnetic flux leakage and enhance the suction.
2. Transfer torque.
The main functions and features of magnetic couplings are as follows.
This magnetic coupling is used conveniently, easily and installation is simple;
2. As a result of the process is to pass by the magnetic torque. Therefore, the magnetic couplings can reduce wear and increase with the coupling surface of life. Besides the work does not require lubrication coupling;
3. The magnetic couplings have the function of automatically adapting to flexible soft-connection;
4. Magnetic couplings have external load and overload limit protection;
5. Magnetic couplings have a slow twist earthquake shock and isolation functions.
