Title:
DISC TYPE MAGNETIC GEAR USING MAGNETISM GATHERING TYPE MAGNETISM ADJUSTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/082379
Kind Code:
A1
Abstract:
The invention relates to the technical field of transmission in mechanical engineering, in particular to a disc type magnetic gear using a magnetism gathering type magnetism adjusting device. The magnetic gear is composed of a driving disc assembly, a driven disc assembly and a magnetism gathering type magnetism adjusting device assembly, and is characterized in that: a magnetism adjusting block of the magnetism gathering type magnetism adjusting device adopts a structure with ½ periodic sine sides and an approximate isosceles trapezoid cross section, in combination with a mechanical structure installed in a matching way, to enhance the reliability of the magnetic gear. Different connection modes can be selected according to the different base materials of the magnetism adjusting block. In order to prevent magnetic leakage at the end, a transverse soft magnetic material is added, the magnetism adjusting device can simultaneously realize the magnetism adjusting and gathering effects, improving the magnetism adjusting performance, and enhancing the magnetism gathering capacity. The permanent magnets of the driving disc and the driven disc are both arranged in a 90-degree Halbach arrangement mode or a compact arrangement mode and the like with higher magnetic energy density. The present invention enhances the torque density of the magnetic gear by the design of the structure of the magnetism adjusting device and the arrangement of the permanent magnet, so that the magnetic gear is widely applied to a high torque working environment.
