磁阻永磁齿轮结构及其动态特性仿真分析

Simulation on the structure and transmission characteristics of reluctance permanent magnet gear

通过对磁阻永磁齿轮的结构分析,对一种传动特性较好的结构形式,详细分析了其在两种形式负载下的传动特性。分析表明,在阶跃负载作用下,其经过短暂启动后,进入平稳运行阶段,启动冲击较大;在线性负载作用下,磁阻永磁齿轮启动时的冲击较阶跃负载作用下的要小,并且其最大转矩传递能力较阶跃负载作用下的要大。根据极弧比的概念对极弧比对转矩传递能力的影响进行了仿真分析,得出了最佳极弧比。

By analizing the structure of reluctance permanent magnet gear,a structure form with good transmission characteristics was proposed,and a detailed analysis was given for transmission characteristics under two kinds of loads.The result shows that under step load,after a short start,the system enters the stable operation stage,with a larger starting impact;under linear load under the reluctance permanent magnet gear has a smaller start impact and higher maximum torque transmission capacity than that under step load.According to the concept of polar arc ratio,the influence of the pole arc ratio on the torque transfer capability is simulated and analyzed,and the optimum arc ratio determined.
