摘要：

调速型鼠笼式异步磁力联轴器即永磁调速器,它的力学参数、磁场分布对其传递能力及整个系统的稳定性与可靠性具有很大的影响,因此有必要对其工作时的轴向力进行深入研究.基于等效面电流法,推导出联轴器在低转差率下的螺旋进给/退出轴向力计算表达式;同时采用电磁场分析软件Magnet对其进行模拟分析,得到了不同啮合长度、不同转差率下的螺旋进给/退出轴向力值,并进行了对比分析.调速型鼠笼式异步磁力联轴器轴向力由完全啮合状态至脱离状态呈现先增大后减小的趋势;在相同输入转速情况下,转差率越大,轴向力越小,在脱离状态时趋于稳定值.这对于调速型鼠笼式异步磁力联轴器以及其它类型磁力联轴器的理论研究、参数设计与优化及其应用都有着一定的理论意义及实际应用价值.

Abstract:

Mechanical parameters and the magnetic field distribution of the adjustable speed squirrel-cage asynchronous magnetic coupling are closely related to the ability to transmit electromagnetic torque and the stability and reliability of the entire system. Therefore, it is necessary to study the axial force on working condition deeply. Based on equivalent surface current method, the calculation expression of rotary feeder/exit axial force was obtained through using three-dimensional analysis. By using Magnet (one kind of electromagnetic field analysis software), the value of rotary feeder/exit axial force was solved under the different length of engagement and different slip ratio, and then the comparative analysis was done. The axial force of adjustable speed radial squirrel-cage asynchronous magnetic coupling showed a trend of decrease after the first increase from complete meshing state to out of state. The greater slip, the smaller axial force, and it got stable value when the adjustable speed squirrel-cage asynchronous magnetic coupling was out of state under the condition of the same input speed. The study on the axial force has a certain theoretical significance and practical value in the field of theory, parametric design optimization and application in the research of adjustable speed squirrel-cage asynchronous magnetic coupling and other types of asynchronous magnetic coupling in the future.
