Example Embodiment

[0039] The working principle of Example 1: the barrel-type magnetic adjustment device is located between the inner and outer rotors, and is connected and fixed with the external base 8 through the support frame 4. The barrel-type magnetic adjustment device needs to ensure good coaxiality with the inner and outer rotors to form a uniform Internal and external air gaps; (1) The working principle of the magnetically regulated magnetic gear: when the rotor is driven at a speed n 1 The number of driving pole pairs is P 1 When the magnet rotates, it will generate a rotational speed of n 1 , the number of pole pairs is P 1 The rotating magnetic field of , after being modulated by the number of R-adjusted magnet blocks 1, will form the number of magnetic pole pairs P. 2 =R-P 1 The harmonic magnetic field of the second order, the rotational speed of the harmonic magnetic field is n 2 =n 1 ×P 1 / P 2 , the number of the harmonic magnetic field and the pole pairs is P 2 The magnet...

Abstract

The invention relates to a superconductive magnetism-isolation-type magnetism adjusting device, and belongs to the technical field of mechanical engineering transmission. The device is characterized by comprising a magnetism adjusting iron block, a superconductive substrate, a heat insulation layer, a supporting frame, a cold conveying pipe, a loop pipe and a refrigerator. The meissner effect of a superconductive material is utilized, when the temperature of the superconductive material is lower than a critical temperature and a superconductive state is formed, the superconductive material repels magnetic lines of force completely out of the superconductive material so that magnetic lines of force of an external magnetic field cannot penetrate through the superconductive material, the direction of the magnetic lines of force is changed and all the magnetic lines of force pass through the magnetism adjusting iron block. An adjustment magnetic field formed after the external magnetic field is adjusted through the magnetism adjusting iron block is different in rotation speed and distribution from an original magnetic field, and accordingly a magnetism transmission device has a speed adjustment function.

Description

technical field [0001] The invention relates to a superconducting magnetic isolation type magnetic adjustment device, which belongs to the technical field of mechanical engineering transmission. Background technique [0002] Magnetic transmission is the integration of transmission technology, manufacturing technology and technological materials. It is based on modern magnetism and uses the magnetic force generated by permanent magnet materials to realize a new technology of non-contact transmission of force or torque. Magnetic transmission technology not only solves the problem of It solves the leakage problem in the transmission process of special industries, and also has some unique advantages that traditional transmission forms do not have: 1) There is no rigid connection between the main and follower parts of the magnetic drive, which can realize non-contact transmission that cannot be realized by traditional mechanical equipment, and at the same time Can reduce mechanic...
