【摘要】 永磁齿轮利用永磁磁场的相互耦合作用产生磁性力来实现非接触传动。采用有限元法求得了永磁齿轮的磁场,进而采用虚功原理求得了磁力矩以及永磁齿轮的矩角特性。通过仿真分析了动轮随主动轮转动的机理。制作了实验模型,实验结果验证了分析方法的正确性。更多还原

【Abstract】 Non-contact drive is realized through magnetic force produced by the coupling function of permanent magnetic field for permanent magnetic gear.Magnetic field of permanent gear is got by adopting finite element method.Therefore,the specialities of magnetic torque and torque angle of permanent gear is got with fictitions power principle.Through analog simulation,the principle of traction wheels follow the rotation of driver wheels is analyzed here.Also,the experiment model is made and the correctness of the test result is verified.更多还原
