[0002] Magnetic drive technology is a new technology that uses the magnetic force generated by permanent magnet materials to realize the non-contact transmission of force or torque. The device that realizes this technology becomes a magnetic drive, and the magnetic coupling is one of them; The coupling uses the principle of magnetic induction to realize the combination and separation of the main and driven shafts of the machine through the magnetic force of the permanent magnet. There is no mechanical contact between the two, which overcomes the fatal defect of machine parts wear, eliminates vibration, and improves the transmission. efficiency, and can adjust the torque and transmission ratio in the process of power transmission arbitrarily, so that the magnetic coupling is widely used in petrochemical, mining, metallurgy, medicine and health, transportation and other fields; some axial asynchronous magnetic couplings are currently The motor uses a manual speed regulating device to adjust the meshing area between the conductor rotor and the permanent magnet to achieve output of different torques, thereby realizing adjustable speed, but the manual adjustment method is cumbersome to operate, and the accuracy is difficult to ensure accurately, so it is not suitable for Application in occasions with high precision requirements; how to accurately adjust the output torque in the magnetic coupling through the remote intelligent control system has become a new topic in the research direction of magnetic technology

[0003] At present, a small number of patents have been researched on this kind of magnetic coupling. In the patent with the related application number CN200910232125.6, a permanent magnetic coupling composed of a cylindrical conductor rotor, a cylindrical permanent magnet rotor, and a regulator is disclosed. Magnetic speed governor, in which the cylindrical conductor rotor is installed on the input shaft, and the cylindrical permanent magnet rotor is installed on the outer ring part of the cylindrical permanent magnet rotor. Although this kind of magnetic coupling can realize the non-contact transmission of torque, but The shape and features of the adjuster are rarely mentioned in the patent; and an adjustable axial asynchronous magnetic coupling is disclosed in the patent application number CN201110219054.3, including: inner rotor assembly ①, outer rotor assembly ② The speed regulating device ③ mainly changes the meshing area between the permanent magnet and the copper bar through the movement transmission between the friction wheel and the driving wheel, and changes the output torque accordingly. The principle of this kind of magnetic coupling speed regulation is simple , convenient, but due to the slippage in the friction wheel movement, the rotation accuracy of the driven wheel is affected, and the transmission efficiency is low; the invention proposes a remote intelligent control adjustable speed axial asynchronous magnetic coupling, which is driven by a remote intelligent controller Controlling the rotation of the motor can well adjust the meshing area between the permanent magnets on the outer rotor and the guide bars on the inner rotor, thereby changing the output torque and realizing precise speed change, so it is obviously different from the above patents
