为了改善磁力齿轮的扭矩传递能力,研究了一种采用鼠笼式调磁装置的同轴式磁力齿轮。通过建立磁力齿轮的瞬态分析有限元模型,模拟分析得到内外气隙长度、永磁体厚度和长径比等结构参数对其传递扭矩能力的影响规律曲线,并得出了机构参数的优化值,模拟了该参数下磁力齿轮的运行情况。基于优化值制作实验样机进行实验研究,实验结果表明,采用此种调磁极片能够实现定传动比传动并能传递一定的扭矩。实验结果与模拟分析具有相似性,表明优化的结构参数能够保证磁力齿轮扭矩传递能力。

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.
