The invention relates to the technical field of transmission in mechanical engineering, in particular to a disk-type magnetic gear using a magnetic-gathering magnetic adjustment device. It is composed of a driving disk assembly, a driven disk assembly and a magnetic concentration type magnetic modulation device assembly. It is characterized in that: the magnetic modulation block of the magnetic concentration type magnetic modulation device adopts a side 1 / 2 period sine wave and an approximate isosceles trapezoid The cross-sectional structure, combined with the mechanical structure of the matching installation, enhances the reliability of the magnetic gear. Depending on the base material of the magnetic block, different connection methods can be selected. In order to prevent magnetic flux leakage at the end, a transverse soft magnetic material is added, and the magnetic modulation device realizes the effects of magnetic modulation and magnetic concentration at the same time, improving the magnetic modulation performance and the magnetic concentration ability. The permanent magnets of the driving disc and the driven disc are all arranged in a 90°Halbach arrangement or a close arrangement with a high magnetic energy density. The invention enhances the torque density of the magnetic gear through the design of the structure of the magnetic adjustment device and the arrangement of the permanent magnets, so that it can be widely used in high-torque working environments.
Description
technical field [0001] The invention relates to the technical field of transmission in mechanical engineering, and relates to a non-contact connected magnetic gear, in particular to a disk-type magnetic gear using a magnetism-concentrating type magnetic adjustment device. It can be applied to non-contact transmission systems with high torque and high and low speed transmission. Background technique [0002] In industrial production, mechanical gears are widely used in various transmission systems due to their fixed transmission ratio, wide range of applicable speed and load, and long life. The contact wear is serious, and the mechanical gear does not have the function of overload protection. These shortcomings will reduce the transmission performance of the mechanical gear and limit its use in certain specific working environments. With the development of modern technology and the improvement of the performance of permanent magnet materials, many scholars have proposed a so...
