摘　　要：基于Ansoft有限元分析,对轴向永磁涡流联轴器的安装误差进行分析,包括轴向间距的变化对输出转矩和转速的影响,不同径向轴间距下转矩的变化,不同端面夹角下转矩和轴向力的变化.通过不同条件下的传递转矩与轴向力对比讨论,得到轴向永磁涡流联轴器安装误差的影响,以及所容许误差范围大小.笔者的研究方法与结论对轴向永磁涡流联轴器的设计与安装提供了参考.The application and development of permanent magnet eddy current coupling are sketched as well as the basic structure and principle. The assembling deviations of the axial permanent magnet eddy-current coupling are analyzed based on the Ansoft software, including the variations of the output torque and rotational speed following the air gaps, the variation of the torque following different radial axial range, the variations of the torque and axial force following different transverse angles. The effects of assembling deviations and the range assembling deviations ensured for the axial permanent magnet eddy current coupling are obtaimed by the comparison of the axial force and torque under different conditions. The research methods and conclusions in the paper provide reference for the design and installation of the axial permanent magnet eddy-current coupling.
