摘　　要：磁力驱动技术实现了转矩无接触传递,解决了普通连接方式中的泄漏问题。在吸收国内外先进磁力驱动设计经验的基础上,进行磁转矩计算;磁路形式采用密封性能好、磁能积利用率高的拉推组合式结构;通过ANSYS对不同磁体厚度和不同工作气隙宽度的磁转子进行磁场分析。结果表明:随永磁体厚度的增加,转矩增加较快,但当厚度增加到一定值时,转矩增加较慢或不明显,并随气隙宽度增加,磁转矩迅速减小。磁体材料采用高矫顽力和高剩余磁感应强度的铷铁硼材料。通过ANSYS有限元分析对隔离套的结构进行优化,并利用Pro/E进行三维造型及机构运动仿真,以利于结构改进,提高结构设计的可靠性和科学性。The no touch transfer of torque was realized by magnet forcing rotary technology ,which solves the problem of leakage at common linking mode. After absorbing the design experience of magnet forcing rotary technology at home and abroad, magnetic torque was calculated,drag-push combination structure was abopted for magnetic circuit which seals well and has high utilization ratio of magnetic energy. The finite element software ANSYS was separately used for magnetic field analysis of the magnetic rotor for different working-gap width and different thickness of magnet. The result shows that：with the thickness of magnet increasing, magnetic torque increases rapidly, however when the thickness of magnet increased to a certain value, magnetic torque increases slower or indistinct ;with the working gap width increasing, magnetic torque reduces rapidly. Magnet material adopts NdFeB per- manent magnet material with high coercive force and high remanence density. The optimization for structure of isolate sleeve was carried out using ANSYS, 3-dimention design and simulation of the whole component was realized based on Pro/E. Then the structure is judged by simulation, which improves element structure and advances rational structural design.
