摘　　要：介绍了矿用永磁调速装置的结构和原理,设计了一种基于正弦曲线的调速沟槽形式,并对调速沟槽的接触应力进行有限元分析计算。将永磁调速装置中的轴向力与气隙值进行函数曲线拟合,结合调速沟槽的特性曲线得出不同气隙下调速所需的扭矩值;通过试验得到执行器实际输出扭矩值,将扭矩的理论计算值与试验结果进行对比,发现两者变化趋势相同,扭矩峰值误差为5.5%,吻合度较高。通过函数曲线拟合的数值计算方法量化了不同气隙下的调速扭矩值,可为永磁调速装置调速机构的研究提供技术支持。Structure and principles of mine-used permanent magnet speed regulator were introduced.A sinusoidal-based speed regulating groove was designed and contact stress of the groove was analyzed by finite element method.Axial force and air gap value in the permanent magnetic speed regulator were fitted by function curve,according to characteristic function curve of the groove,torque values under different air gaps were obtained.Actual output torque of actuator was obtained through test.By comparing theoretical calculation value of torque with the test results,it is found that both have the same change trend and high coincidence degree,peak torque error was 5.5%.Through numerical calculation method of function curve fitting,the value of speed regulation torque under different air gaps is quantified,which canprovide technical support for research of speed regulating mechanism of permanent magnet speed regulator.
