摘　　要：同心式磁力齿轮是一种结构新颖、具有广阔发展前景的新型传动装置,它是利用磁场调制原理实现大转矩传递。本文在同心式磁力齿轮结构的基础上对调磁环进行改进,在调磁环的内侧加入硅钢构成一个机械桥,运用二维有限元法对改进型磁力齿轮模型进行仿真,并计算磁力齿轮电磁场和电磁转矩,同时与普通同心式磁力齿轮磁场和转矩进行比较。计算结果表明,改进型磁力齿轮磁场较普通型磁力齿轮磁场磁密幅值高,其谐波含量较低,转矩也有所提高。这对同心式磁力齿轮转矩密度的提高研究及应用具有重要意义。The concentric magnetic gear is a transmission gear with a novel structure and a promising prospect, by using the magnetic field modulation principle, the large torque transmission is realized. On the basis of concentric magnetic gear structure, the modulation magnet ring is improved, the silicon steel is added on the in- side of the modulation magnet ring to constitute a mechanical bridge. The model of the improved magnetic gear is simulated by using two dimensional （2D） finite element （FE） method, and the magnetic field and electromagnetic torque are calculated. At the same time, the magnetic field and torque are compared with the common gear. The results show that improved magnetic gear magnetic field is higher than normal -type magnetic gear, lower harmonic content, and torque is also improved. It is significant for the research and application of the concentric magnetic gear.
