摘要

偏心磁谐波齿轮(EMHG)可以实现大扭矩、高效率、高传动比的传动。提出了计算气隙磁场的精确解析模型。解析方法基于双曲余切变换法，理论上是准确的。偏心气隙磁场解可由转子偏心影响下的相对磁导函数得到。在此基础上，利用遗传算法对EMHG进行了优化设计。分析结果与Ansoft有限元法计算结果吻合较好，验证了所建分析模型的正确性和有效性。

Exact Analytical Magnetic Field Analysis and Optimization Design of an Eccentric Magnetic Harmonic Gear

The eccentric magnetic harmonic gear (EMHG) can achieve large torque transmission, high efficiency with high gear ratios. Exact analytical model is proposed to calculate the air gap magnetic field. The analytical method is based on the hyperbolic cotangent transformation method, which is accurate in theory. The eccentric air gap magnetic field solutions can be obtained by the relative permeance function derived from the effect of rotor eccentricity. The genetic algorithm based on the proposed analytical method is used to optimize and design the EMHG. The analytical results are in good agreement with Ansoft finite element (FE) method results, which verifies the correctness and validity of the proposed analytical model.
