【摘要】：永磁涡流联轴器是通过电磁感应原理将原动机与工作机联接起来的一种新型联轴器。它无需直接的机械连接,而是利用磁场可穿透一定的空间距离和物质材料的特性和永磁体在运行时产生的交变磁场对内转子鼠笼形成的涡流作用来进行机械能量的传送。永磁涡流联轴器主要由以下三部分组成：主动磁环,从动磁环以及主、从磁环中间的隔离盘。永磁涡流联轴器实现了无机械连接传动,解决了过载保护、主从动轴对中、软启动问题,同时也解决了一些传动装置中密封性要求等问题。目前市场上的永磁涡流联轴器大致可分为径向的和轴向两种。主要的研究方向为如何提高永磁涡流联轴器的传递转矩,而对其传递转矩的平稳性方面研究较少,参考电机的转子斜槽结构对启动所产生的高平稳性,提出将转子斜槽结构应用于深槽鼠笼异步磁力联轴器中,进而得到内转子斜槽鼠笼异步磁力联轴器。采用此种结构能大大削弱永磁涡流联轴器在启动时的振动和噪音。永磁涡流联轴器在各行各业应用越来越广泛,有着巨大的市场效益,有必要对永磁涡流联轴器的装置设计和传动理论进行进一步的设计和研究。本文所研究的永磁涡流联轴器是在径向磁力联轴器的基础上,对深槽鼠笼异步磁力联轴器的内转子采用斜槽结构。对采用斜槽后的永磁涡流联轴器进行齿槽转矩和输出转矩的分析,并据此对其进行结构优化,结合对其涡流、传动效率的进一步分析,最终得出完整的分析结果。
[Abstract]:The permanent magnet eddy current coupling is a new type of coupling which connects the prime mover with the working machine by electromagnetic induction principle. It does not need direct mechanical connection. The mechanical energy is transmitted by the magnetic field which can penetrate a certain space distance and the characteristics of the material and the eddy current effect of the alternating magnetic field produced by the permanent magnet on the inner rotor cage. The permanent magnet eddy current coupling is used to transfer the mechanical energy. It consists of three parts: active magnetic ring, The driven magnetic ring and the isolation disk in the middle of the main and slave magnetic ring. The permanent magnet eddy current coupling realizes the transmission without mechanical connection, which solves the problem of overload protection and soft starting in the main follower shaft alignment. At the same time, it also solves some problems such as seal requirement in transmission device. At present, the permanent magnet eddy current couplings in the market can be roughly divided into radial and axial direction. The main research direction is how to improve the transfer torque of the permanent magnet eddy current couplings, but there is little research on the smoothness of the transfer torque. Referring to the high stability of rotor slotting structure of motor to start up, the rotor slant slot structure is applied to the asynchronous magnetic coupling of deep slot squirrel cage. The induction magnetic coupling of the inner rotor inclined slot cage can be obtained, and the vibration and noise of the permanent magnet eddy current coupling can be greatly reduced by using this structure. Permanent magnet eddy current coupling is more and more widely used in various industries and has great market benefit. It is necessary to further design and study the device design and transmission theory of permanent magnet eddy current coupling. The permanent magnet eddy current coupling studied in this paper is based on the radial magnetic coupling. The internal rotor of the deep slot squirrel cage asynchronous magnetic coupling is constructed with slant slot structure. The tooth groove torque and output torque of the permanent magnet eddy current coupling after adopting the inclined slot are analyzed, and the structure of the coupling is optimized and combined with the eddy current. Further analysis of transmission efficiency, the final complete analysis results.
