Problems solved by technology

[0004] In the Chinese invention patent 201020669057.8, a stator for coaxial magnetic gears is mentioned, including a support mechanism and a magnetic adjustment mechanism. The magnetic adjustment mechanism includes an annular sheath and a number of axially distributed magnetic adjustment core blocks. There is an air groove between the magnet adjustment core blocks; the magnet adjustment core block of the invention is mechanically connected with the annular sheath, which ensures that the magnet adjustment block will not move under the action of large torque, and the mechanical strength of the whole device is improved. ; In the Chinese invention patent 201210432030.0, a kind of I-shaped composite magnetic adjustment device is mentioned, which adopts the mechanism design of the integration of the magnetic adjustment pole piece and the non-magnetic conductive substrate. The contact area of ​​the magnetic substrate overcomes the displacement caused by the radial or axial magnetic force, thereby improving the structural rigidity and strength of the entire magnetic modulation device; but the above two invention patents, the air groove and the non-magnetic substrate are both Absolute magnetic isolation cannot be achieved, and there is a relatively obvious phenomenon of magnetic flux leakage, which weakens the strength of the modulated magnetic field and reduces the transmission performance of the device

Embodiment 1

[0039] The working principle of embodiment 1: the barrel type magnetization device is located between the inner and outer rotors, and is connected and fixed by the support frame 4 with the outer base 8. The barrel type magnetization 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 adjustable magnetic gear: When the rotor is driven at a speed of n 1 Drive the number of magnetic pole pairs as P 1 When the magnet rotates, it will produce a speed of n 1 , The number of pole pairs is P 1 After being modulated by the number of R-adjusting magnet block 1, the number of magnetic pole pairs will be P 2 =R-P 1 Harmonic magnetic field, the speed of the harmonic magnetic field is n 2 =n 1 ×P 1 / P 2 , The number of harmonic magnetic field and magnetic pole pair is P 2 The magnetic fields generated by the permanent magnets on the inner rotor are coupled with each other, so that ...

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.

Technical field [0001] The invention relates to a superconducting magnetic isolation type magnetic modulation 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 scientific and technological materials. It uses modern magnetism as the basic theory and uses the magnetic force generated by permanent magnet materials to realize the non-contact transmission of force or torque; magnetic transmission technology not only solves To solve the leakage problem in the transmission process of special industries, it also has some unique advantages that the traditional transmission form does not have: 1) There is no rigid connection between the main and the follower of the magnetic drive, which can realize the non-contact transmission that cannot be achieved by traditional mechanical equipment. It can reduce mechanical noise and vibratio...
