摘 要:为深入研究内、外永磁体轴向啮合差值对筒式磁力联轴器传动性能的影响,通过Maxwell软件仿真确定磁力联轴器最佳永磁体组数,并对不同轴向啮合差值下筒式磁力联轴器的最大磁感应强度、磁力线分布、轴向中部和端部气隙磁场强度、输出转矩和隔离套涡流损耗进行了有限元分析。计算结果表明:磁力联轴器的气隙磁感应强度符合周期数为8的谐波分布,周期数与永磁体组数相同;轴向啮合差值增大时,磁力联轴器的最大磁感应强度先增后减,端部气隙磁场强度增大,中部气隙磁场强度基本不变,输出转矩和隔离套涡流损耗减小。To study the mechanism of the transmission performance of a cylindrical magnetic coupling affected by axial meshing difference between inner and outer permanent magnets,Maxwell software simulations were used to determine the optimal number of permanent magnet groups.Finite element analysis examined the maximum magnetic induction intensity,magnetic force line distribution,air gap magnetic field intensity at the middle and ends of the axis,output torque,and isolation sleeve eddy current loss of the cylindrical magnetic coupling under varying axial meshing differences.The results revealed that the air gap magnetic induction intensity exhibited a harmonic distribution with a period of 8,matching the number of permanent magnet groups.As the axial meshing difference increases,the maximum magnetic induction intensity first rises and then falls,the end air gap magnetic field intensity increases,the middle air gap magnetic field intensity remains nearly constant,while the output torque and isolation sleeve eddy current loss decrease.This research provides valuable insights for the structural design and performance optimization of cylindrical magnetic couplings.
