20世紀70-80年代，上減速器技術(shù)有了很大的發(fā)展，且與新技術(shù)革命的發(fā)展緊密結(jié)合。通用減速器的發(fā)展趨勢如下：
?、俑咚健⒏咝阅?。圓柱齒輪普遍采用滲碳淬火、磨齒，承載能力提高4倍以上，體積小、重量輕、噪聲低、效率高、可靠性高。
?、诜e木式組合設(shè)計?；緟?shù)采用優(yōu)先數(shù)，尺寸規(guī)格整齊，零件通用性和互換性強，系列容易擴充和花樣翻新，利于組織批量生產(chǎn)和降低成本。
?、坌褪蕉鄻踊?，變型設(shè)計多。擺脫了傳統(tǒng)的單一的底座安裝方式，增添了空心軸懸掛式、浮動支承底座、電動機與減速器一體式聯(lián)接，多方位安裝面等不同型式，擴大使用范圍。
促使減速器水平提高的主要因素有：
?、倮碚撝R的日趨完善，更接近實際(如齒輪強度計算方法、修形技術(shù)、變形計算、優(yōu)化設(shè)計方法、齒根圓滑過渡、新結(jié)構(gòu)等)。
?、诓捎煤玫牟牧?，普遍采用各種優(yōu)質(zhì)合金鋼鍛件，材料和熱處理質(zhì)量控制水平提高。
③結(jié)構(gòu)設(shè)計更合理。
?、芗庸ぞ忍岣叩絀SO5-6級。
?、葺S承質(zhì)量和壽命提高。
?、逎櫥唾|(zhì)量提高。
NTN軸承后橋驅(qū)動車輪運動的重要組成部分。NTN軸承工作中的主要化合物，能承受彎曲和扭矩，同時吸收一些沖擊載荷。車橋整體碳合金淬火鋼和淬火中常用的感應(yīng)加熱后硬化，硬化層深度為4-6mm的，硬度5-55HRC。NTN軸承的生產(chǎn)發(fā)現(xiàn)，經(jīng)常出現(xiàn)NTN軸承燒壞的現(xiàn)象，嚴重影響了生產(chǎn)的NTN軸承及零件感應(yīng)淬火質(zhì)量。試驗表明，NTN軸承燒壞地區(qū)位于線圈225。在工地附近，擴展雙方的故障特征的規(guī)律性。車橋傳感器加熱，除了加熱工件，在三種方式中的主要熱損失的傳感器所產(chǎn)生的熱量。

交流電機調(diào)速方法：
交流電機剛好相反。交流電機結(jié)構(gòu)簡單、慣量小、維護方便，可在惡劣環(huán)境中運行，容易實現(xiàn)大容量化、高壓化、高速化，而且價格低廉。
從節(jié)能的角度看，交流電機的調(diào)速裝置可以分為調(diào)速裝置和低效調(diào)速裝置兩大類。調(diào)速裝置的特點是：調(diào)速時基本保持額定轉(zhuǎn)差，不增加轉(zhuǎn)差損耗，或可以將轉(zhuǎn)差動率回饋至電網(wǎng)。
低效調(diào)速裝置的特點是：調(diào)速時改變轉(zhuǎn)差，增加轉(zhuǎn)差損耗。
調(diào)速方法包括：改變極對數(shù)調(diào)速—鼠籠式電機變頻調(diào)速—鼠籠式電機串級調(diào)速—繞線式電機換向器電機調(diào)速—同步電機。
低效調(diào)速方法包括：定子調(diào)壓調(diào)速—鼠籠式電機電磁滑差離合器調(diào)速—鼠籠式電機轉(zhuǎn)子串電阻調(diào)速—繞線式電機。

1、異步型
異步型交流伺服電動機指的是交流感應(yīng)電動機。它有三相和單相之分，也有鼠籠式和線繞式，通常多用鼠籠式三相感應(yīng)電動機。其結(jié)構(gòu)簡單，與同容量的直流電動機相比，質(zhì)量輕1/2，價格僅為直流電動機的1/3。缺點是不能經(jīng)濟地實現(xiàn)范圍很廣的平滑調(diào)速，必須從電網(wǎng)吸收滯后的勵磁電流。因而令電網(wǎng)功率因數(shù)變壞。
這種鼠籠轉(zhuǎn)子的異步型交流伺服電動機簡稱為異步型交流伺服電動機，用IM表示。
