【摘要】：摆线永磁齿轮是通过内转子本身自转和公转来传递转速,可以获得较高的传动比和转矩密度。为改善漏磁、提高永磁体利用率,将永磁体采用Halbach排列,根据其工作原理设计制造了一台样机。通过有限元模拟摆线永磁齿轮的磁场分布和静态转矩特性。与一般结构相比,采用90°Halbach结构时最大转矩密度的平均值可提高30%左右,且最大转矩密度的波动较小,传动更平稳。最后,通过实验分别测试转子不同转角时的传动转矩,所得结果与模拟结果比较吻合。结果表明基于Halbach排列的摆线永磁齿轮可以有效的改善漏磁现象,获得更高的转矩密度。
[Abstract]:The cycloidal permanent magnet gear transfers the rotational speed through the rotation and rotation of the inner rotor itself, which can obtain higher transmission ratio and torque density. In order to improve magnetic flux leakage and improve the utilization ratio of permanent magnets, a prototype was designed and manufactured according to the working principle of the permanent magnets arranged by Halbach. The magnetic field distribution and static torque characteristics of cycloid permanent magnet gear were simulated by finite element method. Compared with the general structure, the average maximum torque density of 90 掳Halbach structure can be increased by about 30%, and the fluctuation of the maximum torque density is smaller and the transmission is more stable. Finally, the torque of the rotor with different rotation angles is measured by experiments, and the results are in good agreement with the simulation results. The results show that cycloidal permanent magnetic gears based on Halbach arrangement can effectively improve magnetic flux leakage and obtain higher torque density.
