摘要

设计出一种基于Halbach充磁阵列的双摆线式永磁齿轮（Double cycloid permanent magnetic gear，DCPMG）。给出了DCPMG运行机理和初步参数的设计计算方法，通过空间电磁谐波法建立了传动比的计算模型；并通过等效电流法和麦克斯韦张量法给出了内、外层气隙的电磁转矩表达式；基于Ansoft Maxwell 2D建立了DCPMG的有限元模型，并据此验证了初选模型的正确性；通过控制变量法对DCPMG气隙长度、偏心距、轭铁厚度及永磁体厚度进行了仿真优化。结果表明，优化后的DCPMG转矩密度可达353 kN·m/m,3,，较初选模型提升了约10%。

Abstract

A double cycloid permanent magnetic gear （DCPMG） based on Halbach magnetizing array is designed. The operation mechanism of DCPMG and the design and calculation method of preliminary parameters are given，the calculation model of transmission ratio is established by space electromagnetic harmonic method.The expressions of electromagnetic torque of inner and outer air gap are given by equivalent current method and Maxwell tensor method.Based on Ansoft Maxwell 2D，a finite element model of DCPMG is established，and the correctness of the primary model is verified.The air gap length，eccentricity，yoke thickness and permanent magnet thickness of DCPMG are simulated and optimized by control variable method. The results show that the torque density of the optimized DCPMG can reach 353 kN, $\cdot$ ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=34817298&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=34817290&type=,1.86266661,2.62466669,m/m,3,，which is about 10% higher than that of the primary model.
