A Halbach Array Coupler

Abstract

The invention belongs to the technical field of magnetic induction, in particular to a Helbeck array coupler which comprises an input shaft, an input end cover, a bearing group, an output shaft, an output end cover, a shell, a cooling mechanism and a buffer mechanism. The bearing group comprises a first bearing and a second bearing. The input end cover and the output end cover are connected through the shell. The input shaft is fixedly connected on the outer end of the input end cover through screws. The first bearing is rotatably installed in the inner side wall of the input end cover. An axial copper conductor is fixedly installed on the inner surface of the input end cover. The coupler is mainly used for solving the problem that the internal parts are damaged due to shock force when theexisting magnetic coupler is used on the truck in a perennial hot area and the magnetism in the coupler is liable to decrease or disappear in the high temperature environment, and the magnetic flux leakage phenomenon occurs in the magnetic coupler and leads to the loss of the magnetic induction line and thus the transmission efficiency of the magnetic coupler is influenced.

Description

technical field [0001] The invention belongs to the technical field of magnetic induction, in particular to a Halbach array coupler. Background technique [0002] In a microwave system, it is often necessary to divide the microwave power of one path into several paths in proportion, which is the problem of power allocation. The components that realize this function are called power distribution components or couplers, which mainly include: directional couplers, power dividers and various microwave branch devices. [0003] The Halbach Array is a magnet structure, which is an approximate ideal structure in engineering, and the goal is to generate the strongest magnetic field with the least amount of magnets. In 1979, American scholar Klaus Halbach discovered this special permanent magnet structure when he was doing electron acceleration experiments, and gradually perfected this structure, and finally formed the so-called "Halbach" magnet. With the gradual development of the m...

AI Technical Summary

Problems solved by technology

The present invention is mainly used to solve the problem that when the existing magnetic coupler is used on a truck in a perennially hot area, the internal parts will be damaged due to the vibration force, and in such a high temperature environment, the magnetism in the coupler will easily decrease or disappear. At the same time, due to the magnetic flux leakage phenomenon of the magnetic coupler, it will cause the loss of the magnetic induction line, which will affect the transmission efficiency of the magnetic coupler.
