高性能同轴式磁力齿轮结构设计与实验研究
Design and Experiment of a High-performance Coaxial Magnetic Gear
摘要
Abstract
In order to improve the torque transmission ability of a magnetic gear,a coaxial magnetic gear of modulating pole-pieces squirrel-cage structure was developed.A finite element model of transient analysis of the magnetic gear was built to obtain the law curve of transmission torque affected by a series of structural parameters,such as air gap,the thickness of permanent magnet and length-diameter ratio,as well as the optimal value of these structural parameters.The operation of the magnetic gear with these parameters was simulated.An experimental prototyping was designed based on the optimal values and tests.The experimental results show that fixed ratio drive and transmission torque can be achieved using this modulating pole-pieces,and verify that the optimal structural parameters can ensure torque transmission ability of magnetic gear,which indicates high similarity with simulation analyses.关键词
