Novel single-pole magnet rotating superconducting coupler

Abstract

The invention relates to the technical field of transmission in mechanical engineering, and concretely relates to a novel single-pole magnet rotating superconducting coupler. The coupler is composed of a driving permanent magnet disc assembly, a driven conductor disc assembly and a low-temperature constant-temperature device, a speed regulating device is installed on the driving permanent magnet disc assembly, the driven conductor disc assembly is arranged in the low-temperature constant-temperature device, and a superconducting coil is installed in a driven frame. And the driven conductor disc assembly is arranged in a cryostat filled with liquid nitrogen. The permanent magnet disc can be used as a driving disc to drive the conductor disc to rotate or vice versa. The speed regulating device adopts a bevel gear speed regulation mechanism, and the air gap flux density is changed along with the change of the air gap thickness, the opposite area and the permanent magnet arrangement mode between a driving disc and a driven disc, so that the speed regulation is realized. In addition, by changing the superconducting state of the coil, the direction and the magnetism gathering degree of magnetic lines can be changed, and then the air gap flux density is changed to achieve speed regulation.

Description

technical field [0001] The invention relates to the technical field of transmission in mechanical engineering, and is a non-contact magnetic coupler for torque transmission, in particular a novel unipolar magnet rotary superconducting coupler. It can realize the power transmission between the power source and the load end without mechanical contact, and is suitable for occasions that need to transmit power between two different environments. Background technique [0002] Mechanical couplings are an important part of mechanical transmission systems and are widely used in many fields such as mining, metallurgy, aviation and chemical industry, but due to the problems of elastic force and moment caused by axial deviation during installation, as well as radial and angular Misalignment tends to cause vibration and noise. The magnetic coupling has the characteristics of non-contact connection, which can effectively solve this problem. Therefore, in some high-torque vibration occas...

Problems solved by technology

However, in this invention, the conductor plate is a common solid conductor structure composed of ring conductors and yokes, and there is no material performance requirement for the main and driven plates, so it does not consider the impact of high temperature on the materials of the main and driven plates. Therefore, the coupler is prone to high temperature and heat problems in heavy-load starting occasions, especially in heavy-load fields such as ship propulsion and wind power generation, resulting in insufficient load capacity of the coupler.
