超导调制盘形磁性齿轮的研究与设计

Research and Design on Superconducting Modulation Disc Magnetic Gear

针对齿轮在机械传动中出现的转矩密度低等现象,根据同轴磁性齿轮传动的工作原理和超导材料在临界温度时会出现的"迈斯纳效应",设计出盘形非接触式磁性齿轮,并运用超导材料作为阻磁块来改进调制环,替代了传统的环氧树脂等材料。通过建立三维模型设计出传动比为7.4的齿轮传动,并进行有限元仿真分析,证明了超导调制盘形磁性齿轮的设计比传统接触式磁性齿轮在转矩密度方面有明显提升,在传递转矩方面也达到了传统齿轮的水平。

Gear is widely used in mechanical transmission.But the phenomenon such as low torque density is inevitable.According to the working principle of coaxial magnetic gear transmission and the critical temperature when superconducting material occurs ＂ Meissner effect＂,a non-contact magnetic gear was designed.Superconducting materials were used as magnetic blocks to improve modulation ring,replacing the traditional materials such as epoxy resin.Through the established three-dimensional model and finite element simulation analysis,it was proved that the superconducting modulation disc magnetic gear design has improved significantly in the torque density than traditional non-contact magnetic gear.In terms of transmission torque,the new design has reached the level of traditional gear.
