Anti-leakage magnetic suspension type radial transmission magnetic coupling

Abstract

The invention discloses an anti-leakage magnetic suspension type radial transmission magnetic coupling which comprises a driving shaft, a driven shaft and a radial magnetic coupling arranged between the driving shaft and the driven shaft. The radial magnetic coupling comprises a magnetic inner rotor, a magnetic outer rotor and a flange isolation hood, and a placement deep groove for placing the magnetic inner rotor is formed in the center of the upper end face of the flange isolation hood; a plurality of bolt fixing holes are annularly arrayed along the edge of the flange isolation hood, an annular groove is further formed between the bolt fixing holes and the placement deep groove, a sealing ring is arranged in the annular groove, and the magnetic inner rotor, the flange isolation hood and the magnetic outer rotor are all in a suspended non-contact state. The anti-leakage magnetic suspension type radial transmission magnetic coupling is simple in structure and is convenient to install and use, the non-contact connection transmission between shafts can be realized, and the vacuum transmission and sealed transmission are realized to convey torque, so that mechanical wear caused by transmission is reduced, the risk of leakage is avoided, and the anti-leakage magnetic suspension type radial transmission magnetic coupling has the advantages of long service life, no maintenance, strong shock resistance and good sealing effect, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of shaft couplings, in particular to an anti-leakage magnetic suspension radial transmission magnetic shaft coupling. Background technique [0002] Most of the couplings on the market are contact couplings, that is, the contact coupling shaft is installed between two shafts to make them rotate together and transmit torque, but it is necessary to ensure high precision between the two shafts during installation. Requirements, and during long-term use, it will cause noise, dust and wear and aging of the coupling. In the later maintenance, it will take a lot of time, energy and maintenance costs. [0003] At present, a small part of the market uses magnetic couplings to replace contact couplings to achieve non-contact transmission, so as to achieve no wear, noise and dust, so it is widely used, such as petrochemical, medical equipment , Vacuum equipment, aerospace equipment and other high-end equipment fields, ...
