Adjustable axial asynchronous magnetic force coupler

Abstract

The invention relates to the technical field of mechanical engineering transmission, in particular to an adjustable axial asynchronous magnetic force coupler. The adjustable axial asynchronous magnetic force coupler is mainly suitable for power transmission devices in the industries such as mines, metallurgy, aviation and the like. The coupler comprises an inner rotor assembly (1), an outer rotorassembly (2), a speed regulation device (3) and a distance sleeve (7), wherein the speed regulation device (3) is composed of a sleeve III (2), a sleeve I (3), a sleeve II (4), a rotation handwheel (11), a friction wheel driving wheel (12), a friction wheel driven wheel (13), a fixed sleeve (14) and double lines of angular contact ball bearings (15). The speed regulation device (3) of the adjustable axial asynchronous magnetic force coupler causes a meshed area between a permanent magnet (6) and a copper bar (10) to be changed by movement transmission between the friction wheel driving wheel and the friction wheel driven wheel, thereby realizing the purpose that the linearity of an output torque is stably changed, realizing the soft start function of the motor, and expanding the application range of the magnetic force coupler. In addition, the transmission mechanism formed by the inner rotor assembly and the outer rotor assembly is searched, the transmission mechanism which can provide stable torque, large power and high efficiency under different occasions is proposed, and the function of the magnetic force coupler is expanded.

[0002] Magnetic drive technology is a new technology that uses the magnetic force generated by permanent magnet materials to realize the contactless transmission of force or torque. The device that realizes this technology is called a magnetic drive, and the magnetic coupling is one of them; The biggest feature of the magnetic coupling is that it completely seals the inner rotor and the driven shaft, turning the dynamic seal into a static seal, so it is widely used in petroleum, chemical, pharmaceutical and other industries to reduce pollution and leakage; similar to permanent magnet The principle of the motor, the magnetic coupling can be divided into two types: synchronous and asynchronous. At present, the widely used magnetic coupling is the synchronous cylindrical magnetic coupling. Under severe conditions, demagnetization will occur, which will limit its application range; in addition, under harsh working conditions, how to realize the low-load start-up and full-load operation of the motor, how to effectively solve the problem of motor heating and failure when the motor load starts, and realize the coupling High-efficiency transmission is one of the key issues to expand the application range of magnetic couplings. Based on the above characteristics, it is necessary to study asynchronous cylindrical magnetic couplings.
