摘　　要：机械特性与调速特性是调速型磁力耦合器的两项重要特性,通过对这两项特性的深入研究可以使得耦合器更好地实现调速功能。以盘式实心异步磁力耦合器为研究对象,建立其传动转矩的计算公式,从而推导出恒转矩负载与变转矩负载下的调速关系计算模型,并对转矩与调速关系进行了离散化求解。运用有限元法进行了磁力耦合器两种工作特性的模拟分析,获得了机械特性曲线与调速特性曲线,确定了该耦合器在恒转矩、变转矩两种负载下调速的最佳气隙区间;并试验测试了恒转矩负载与变转矩负载下的调速关系,从而验证了理论计算与模拟分析的正确性。For adjustable-speed magnetic couplers, mechanical properties and adjustable-speed characteristics are both important characteristics. In order to realize the speed regulating function better, these two characteristics above should be studied deeply. An axial-flux solid asynchronous magnetic coupler was proposed, and the calculation model of the transmitted torque was established. From this, the adjustable-speed relationship expressions were derived under the constant torque load and variable load torque conditions, respectively. Moreover, the relationships between the torque and the speed regulation were solved by discretization. In addition, the above two working characteristics of the coupler were simulated by finite element method, respectively. Particularly, the curves of mechanical property and adjustable-speed characteristic were also obtained, and the optimal air gap control ranges under the two different conditions of the constant torque load and variable torque load were determined. Furthermore, the adjustable-speed relationships when the constant torque load or variable torque load were verified experimentally, and the experimental results are in good agreement with the results of theoretical calculation and simulation analysis.
