Disc magnetic coupling(also planar magnetic coupling) consists of two half hubs with powerful magnets. The torque applied to one disc is transferred through an air gap to the other disc. The transmittable torque can be varied by adjusting the air gap. Using the principle of interaction between the attraction and repulsion of strong magnets, It’s a power transmission device for non-contact space transmission

 

The requirements for the installation environment of disc magnetic coupling are relatively low. It adopts multiple N-S rare earth magnets. When the motor rotates, N pole and S pole attract each other to form torque. And in a certain range of torque, to achieve synchronous rotation.

 

 

 

1. Magnetic coupling has overload protection function, which improves the safety and reliability and completely eliminates the damage;
2. No contact, zero wear, easy installation, anti-vibration, anti-explosion, can be isolate and anti-leakage;
3. Non-contact magnetic disc coupling allows the device to work in extreme environment, like aggressive, toxic, explosive, precious or flammable gases and gas mixtures;
4. The torque and speed transmission required by the device can be achieved by adjusting the air gap, and the energy saving effect is remarkable;
5. Magnetic disk coupling has a compact structure and no other auxiliary equipment required for installation. The torque is transmitted through the air gap, so there is no direct contact between the two parts, that there will be no wearing parts, and can reduce up to 80% of vibration, prolonging the life of all parts.

 

Disc magnetic couplings is configured so that the magnetic flux is transferred about the flat end faces of the cylindrical assemblies. The two components are attracted to one and other axially, and typically require additional thrust bearing support for proper integration.

 

Axial misalignment – Mildly Tolerant. The amount of torque transmission is directly proportional to the axial spacing and number of magnets utilized in the design. Small variations in air gap may lead to large changes in torque

 

Radial misalignment – Highly Tolerant.

 

Angular misalignment – Tolerant. Due to the relationship between torque output and axial spacing, high angular misalignment may lead to unexpected torque reductions.

 

 

The magnetic transmission technology has realized a new technological revolution in the history of global transmission, and will definitely bring unprecedented economic benefits to mining business.
