| 摘 要： | 磁力传动重质残油齿轮泵磁耦合器扭矩计算为三位磁场计算，边界条件复杂，加之漏磁、磁性材料参数误差等影响，求解较困难．导出精确求解磁耦合器扭矩的解析解，结果与实验解相符．并根据相似原理给出永磁体的长径比L/D=2/3~1，导磁材料径向厚度t=(1.5~2)L ( 为磁体厚)，可供设计时参考。

| Abstract: | The torque calculating of magnetic coupling of the heavy still bottoms gear is difficult because of 3 dimensions fields and the complex final conditions added the leakage and tolerant of materials performance． It derived the torque formulary of the coupling by analyzing and conrformed by experiment·It also gave the ration of length and diameter of the permanent magnet L/D=2/3~1，and the thick of conductor radial t=(1.5~2)L by similar principle．It can be reference in magnetic coupling designing． |
