摘　　要：介绍了永磁涡流联轴器的结构与工作原理,根据涡电流透入深度,运用电磁场理论推导了永磁涡流联轴器的涡电流密度表达式,将涡电流去磁效应折算到永磁铁上,根据涡电流表达式推导了永磁涡流联轴器传递转矩的计算公式,该计算公式反映了永磁涡流联轴器各设计参数的相互关系,且理论计算值与试验值基本吻合,说明该方法是可行的,可用于指导永磁涡流联轴器产品的设计和开发。The structure and working principle of the permanent eddy-current coupling are presented. The depth of penetra- tion is involved and the expressions of the eddy-current density are derived according to the eleclxomagnetic field theory. Formulas of transmit-torque calculation of the permanent magnetic coupling are derived from the eddy-current expression with converting the demagnetizing effect of the eddy-current to the permanent magnet. The expression shows that the calculating parameters correlate to each other,the result of theoretical calculation generally meets with the experimental values, and the proposed method is feasible and can be used to the design and development of the permanent magnetic coupling.
