Abstract

The invention provides a magnetic coupling and a mounting method thereof. The magnetic coupling comprises an inner permanent magnet rotor, an outer permanent magnet rotor and a plurality of positioning connectors, wherein the inner permanent magnet rotor comprises an inner permanent magnet and an inner cylinder part for bearing the inner permanent magnet, and the outer wall of the inner cylinder part is provided with an annular flange convex radially; the outer permanent magnet rotor comprises an outer permanent magnet and an outer cylinder part for bearing the outer permanent magnet, one side surface of the outer cylinder part is provided with an annular flange convex radially, and the outer cylinder part sleeves the inner cylinder part to enable magnetic poles of the inner permanent magnet and the outer permanent magnet to be mutually matched and enable an air gap to be left; and the plurality of positioning connectors are uniformly and circumferentially arranged around the axis of the coupling, and are detachably connected between the end surface of the outer cylinder part and the annular flange of the inner cylinder part to enable the two to be connected and positioned. The inner permanent magnet rotor and the outer permanent magnet rotor are not adsorbed together, the coaxiality of the two permanent magnet rotors are ensured, stability and reliability during a high-speed rotation process can be ensured, and thus, the structure is compact, the mounting is convenient, the weight is light, and the operation is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of shaft couplings, in particular to a magnetic coupling and an installation method thereof. Background technique [0002] Magnetic coupling is a coupling that transmits torque by magnetic parts, which is very suitable for the transmission of torque between internal and external parts of toxic, harmful and high-pressure vessels. Magnetic couplings generally have two forms: disc-shaped and cylindrical-shaped. Since the disk-shaped coupling is composed of two facing ring magnets and the spacer, and there is an axial force between the two ring magnets, especially when the transmission power is large, the axial force is very large, and it is very difficult to overcome it. Tricky, generally less used. [0003] Cylindrical couplings usually include an inner permanent magnet rotor and an outer permanent magnet rotor sleeved outside the inner permanent magnet rotor. Magnetic steel (ie permanent magnets) are instal...
