摘要
在理论分析磁场调制式磁齿轮工作机理的基础上,设计了一种传动比为2.67的圆筒型直线磁场调制式磁力齿轮,并应用有限元方法分析计算了该直线齿轮的气隙磁密、静态和动态推力特性,计算结果充分验证了设计的合理性。在此基础上,分析了调磁环尺寸对该齿轮输出力矩的影响及变化规律,为直线型磁力齿轮的参数优化提供了依据,并优化调磁环相对宽度为0.6、厚度为3mm、高速侧气隙宽度为1.2mm。
On the basis of theoretical analysis of the working mechanism of traditional magnetic field mod- ulation gear, a cylinder type linear magnetic gear is designed, whose transmission ratio is 2.67. Its air - gap flux density and static thrust characteristics and dynamic thrust characteristics are calculated by using the finite element analysis method. The correctness of the design is validated through the calculate results. Based on the above, the influence of magnetic field modulate ring size on the gear static thrust and the change rule of the in- fluence are analyzed, and a basis for parameter optimization of a linear magnetic gear is provided. At the last, the optimization of relative width of magnetic field modulate ring is to 0.6 and the thickness to 3 mm, the air gap width of high- speed side to 1.2 ram.
