【摘要】：永磁渦流聯(lián)軸器是通過電磁感應原理將原動機與工作機聯(lián)接起來的一種新型聯(lián)軸器。它無需直接的機械連接,而是利用磁場可穿透一定的空間距離和物質(zhì)材料的特性和永磁體在運行時產(chǎn)生的交變磁場對內(nèi)轉(zhuǎn)子鼠籠形成的渦流作用來進行機械能量的傳送。永磁渦流聯(lián)軸器主要由以下三部分組成：主動磁環(huán),從動磁環(huán)以及主、從磁環(huán)中間的隔離盤。永磁渦流聯(lián)軸器實現(xiàn)了無機械連接傳動,解決了過載保護、主從動軸對中、軟啟動問題,同時也解決了一些傳動裝置中密封性要求等問題。 目前市場上的永磁渦流聯(lián)軸器大致可分為徑向的和軸向兩種。主要的研究方向為如何提高永磁渦流聯(lián)軸器的傳遞轉(zhuǎn)矩,而對其傳遞轉(zhuǎn)矩的平穩(wěn)性方面研究較少,參考電機的轉(zhuǎn)子斜槽結(jié)構(gòu)對啟動所產(chǎn)生的高平穩(wěn)性,提出將轉(zhuǎn)子斜槽結(jié)構(gòu)應用于深槽鼠籠異步磁力聯(lián)軸器中,進而得到內(nèi)轉(zhuǎn)子斜槽鼠籠異步磁力聯(lián)軸器。采用此種結(jié)構(gòu)能大大削弱永磁渦流聯(lián)軸器在啟動時的振動和噪音。 永磁渦流聯(lián)軸器在各行各業(yè)應用越來越廣泛,有著巨大的市場效益,有必要對永磁渦流聯(lián)軸器的裝置設計和傳動理論進行進一步的設計和研究。 本文所研究的永磁渦流聯(lián)軸器是在徑向磁力聯(lián)軸器的基礎(chǔ)上,對深槽鼠籠異步磁力聯(lián)軸器的內(nèi)轉(zhuǎn)子采用斜槽結(jié)構(gòu)。對采用斜槽后的永磁渦流聯(lián)軸器進行齒槽轉(zhuǎn)矩和輸出轉(zhuǎn)矩的分析,并據(jù)此對其進行結(jié)構(gòu)優(yōu)化,結(jié)合對其渦流、傳動效率的進一步分析,最終得出完整的分析結(jié)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.
