中文摘要：

针对一台永磁内转子极对数为7,永磁外转子极对数为15的高性能磁力齿轮,为了研究其传动性能,讨论了磁力齿轮的3种运行方式,推导了其传动比关系,并在此基础上,推导了传动效率、转矩与传动比之间的关系公式;在转速较低的情况下,当传动效率为1,输出转矩仅为输入转矩与传动比的乘积。为此,运用有限元软件,对3种运动方式在转速较低的情况下分别进行了双转子转动时的动态仿真分析,得到了不同负载对转矩的影响。最后通过传动性能实验装置进行实验验证,测得不同负载下磁力齿轮的转矩。结果表明,在转速较低的情况下,输入转矩随着输出转矩的增大成线性增加,且输出转矩与输入转矩的比值近似等于传动比的值,这一研究可用于在传动比已知情况下的动态转矩的估算。

英文摘要：

Aiming at the high-performance magnetic gear with 7 pole pairs of permanent magnet inner rotor and 15 pole pairs of permanent magnet outer rotor,in order to study the working principle and transmission performance,the three different running manners are discussed,their gear ratios relation are derived,and the relationship among efficiencies,torques and gear ratios are also derived. When the speeds is lower,the efficiency is almost equal to 1,thus the out torque is equal to the input torque times its gear ratio. Also,the three different running manners under lower speeds are dynamically simulated by using the finite element analysis software,and the influence of different loads on torques is obtained. Then,the input torque and output torque are measured under different loads by transmission experiment platform respectively. The results show that the input torque increases linearly with the increase of the output torque,and the ratio of output and input torque is equal to the gear ratio. All these can be used to estimate the dynamic torque when the transmission ratio is given.
