摘　　要：基于磁场调制式永磁齿轮运行原理,提出了一种新型磁力增速齿轮传动系统,即将多个高转矩密度的磁场调制式永磁齿轮级联起来,使其成为具有过载保护、隔离冲击与振动且无须润滑等优点的高转矩密度的增速传动系统。通过有限元法详细分析了永磁齿轮增速传动系统中各组成部分的损耗产生机理及影响因素,并通过控制变量法对连接模块永磁齿轮的内外永磁体、调磁环、外转子轭铁等结构进行优化,使得整个增速系统效率提高至91.1%。Based on the operating principle of magnetic field modulation permanent magnet gears,a new type of magnetic speed increasing gear transmission system is proposed.It is cascading high torque density magnetic field modulated permanent magnet gears enable substantial power transmission with elevated transmission ratios.This high torque density transmission system has the advantages of overload protection,isolation of impacts and vibrations and no need for lubrication.An efficiency of 91.1%is achieved by selectively optimizing structural parameters such as internal and external permanent magnets,stationary ring and outer yoke iron in the connection module.
