磁场调制式磁力齿轮具有无摩擦、无油污、少维护以及安装简便等优点,是一种具有广阔发展前景的传动装置。从内、外转子极对数比方面对磁力齿轮进行研究,建立了不同传动比的磁力齿轮模型,比较了不同模型的输入、输出转矩波形,分析了内转子极对数(,P,1,)和外转子极对数(,P,2,)对转矩脉动的影响。根据磁场调制原理和空间磁场谐波分布,磁力齿轮两转子转矩脉动受,P,1,和,P,2,影响较大。研究结果表明,选择,P,1,=4,内、外转子极对数比为1∶,n,+0.25或1∶,n,+0.75(,n,为自然数)的磁力齿轮,可以有效降低转矩脉动。
The field modulation magnetic gear is a kind of transmission device with broad development prospects. It has the advantages of no friction, no pollution, less maintenance and easy installation. The magnetic gear models with different transmission ratio are established. The input and output torque waveforms of different models are compared. The influences of the number of pole pairs of inner rotor (,P,1,) and the number of pole pairs of outer rotor (,P,2,) on torque ripple are analyzed. According to the principle of magnetic field modulation and spatial magnetic field harmonic distribution, the torque ripple of magnetic gear is greatly affected by ,P,1, and ,P,2,. The research results show that the torque ripple can be effectively reduced by selecting the magnetic gear with ,P,1,=4, ,P,1,:,P,2,=1:,n,+0.25 or 1:,n,+0.75 (,n, is a natural number).
