摘要

双永磁轮非接触永磁力直线驱动装置是一种依靠永磁力进行长距离直线传动的磁力驱动装置。双永磁驱动轮与铁质导轨齿条之间没有直接的表面接触，通过控制伺服电机带动永磁驱动轮转动，依靠永磁体对铁质导轨齿条凸齿产生的磁力实现装置的直线驱动。首先，根据双永磁轮磁力驱动装置的结构建立磁力数学模型；其次，利用有限元方法对驱动装置的水平驱动力和竖直干扰力进行仿真分析，将仿真结果与单永磁轮驱动装置的仿真结果进行对比分析。对比分析的结果说明，双永磁轮非接触永磁力直线驱动装置不仅消除了纵向竖直干扰力的干扰，增大了驱动装置的水平驱动力，同时消除了驱动装置在驱动过程中的反向间隙，使导轨在水平方向受力平衡，大大提高了驱动装置的驱动效率。

Abstract

The non-contact permanent magnet force linear driving device of double permanent magnet wheel is a magnetic driving device for long-distance linear transmission by means of permanent magnet force. There is no direct surface contact between the double permanent magnet driving wheel and the iron rail rack，and the servo motor is controlled. The permanent magnet driving wheel is driven by the servo motor，and the device is driven by the magnetic force generated by the permanent magnet to the iron guide rack convex teeth. Firstly，the mathematical model of the magnetic force is established according to the structure of the dual permanent magnet wheel magnetic drive device. Secondly，the finite element method is used to simulate the horizontal driving force and the vertical interference force of the driving device，and the simulation result is compared with the single permanent magnet wheel driving device. The simulation results are compared and analyzed. Through comparative analysis，it is shown that the dual permanent magnet wheel non-contact permanent magnet force linear drive device not only eliminates the interference of longitudinal vertical interference force，but also increases the horizontal driving force of the driving device，and eliminates the backlash of the driving device during the driving process. The rail is balanced in the horizontal direction，which greatly improves the driving efficiency of the driving device.
