交流伺服電機(jī)的基本類型
長(zhǎng)期以來(lái)，在要求調(diào)速性能較高的場(chǎng)合，一直占據(jù)主導(dǎo)地位的是應(yīng)用直流電動(dòng)機(jī)的調(diào)速系統(tǒng)。但直流電動(dòng)機(jī)都存在一些固有的缺點(diǎn)，如電刷和換向器易磨損，需經(jīng)常維護(hù)。換向器換向時(shí)會(huì)產(chǎn)生火花，使電動(dòng)機(jī)的速度受到限制，也使應(yīng)用環(huán)境受到限制，而且直流電動(dòng)機(jī)結(jié)構(gòu)復(fù)雜，制造困難，所用鋼鐵材料消耗大，制造成本高。而交流電動(dòng)機(jī)，特別是鼠籠式感應(yīng)電動(dòng)機(jī)沒(méi)有上述缺點(diǎn)，且轉(zhuǎn)子慣量較直流電機(jī)小，使得動(dòng)態(tài)響應(yīng)更好。在同樣體積下，交流電動(dòng)機(jī)輸出功率可比直流電動(dòng)機(jī)提高10﹪～70﹪，此外，交流電動(dòng)機(jī)的容量可比直流電動(dòng)機(jī)造得大，達(dá)到更高的電壓和轉(zhuǎn)速?，F(xiàn)代數(shù)控機(jī)床都傾向采用交流伺服驅(qū)動(dòng)，交流伺服驅(qū)動(dòng)已有取代直流伺服驅(qū)動(dòng)之勢(shì)。

減速器是原動(dòng)機(jī)和工作機(jī)之間的獨(dú)立的閉式傳動(dòng)裝置，用來(lái)降低轉(zhuǎn)速和增大轉(zhuǎn)矩，以滿足工作需要，在某些場(chǎng)合也用來(lái)增速，稱為增速器。
選用減速器時(shí)應(yīng)根據(jù)工作機(jī)的選用條件，技術(shù)參數(shù)，動(dòng)力機(jī)的性能，經(jīng)濟(jì)性等因素，比較不同類型、品種減速器的外廓尺寸，傳動(dòng)效率，承載能力，質(zhì)量，價(jià)格等，選擇的減速器。 [編輯本段]減速器分類 減速器的類別、品種、型式很多，目前已制定為行（國(guó)）標(biāo)的減速器有40余種。減速器的類別是根據(jù)所采用的齒輪齒形、齒廓曲線劃分；減速器的品種是根據(jù)使用的需要而設(shè)計(jì)的不同結(jié)構(gòu)的減速器；減速器的型式是在基本結(jié)構(gòu)的基礎(chǔ)上根據(jù)齒面硬度、傳動(dòng)級(jí)數(shù)、出軸型式、裝配型式、安裝型式、聯(lián)接型式等因素而設(shè)計(jì)的不同特性的減速器。

一般在35轉(zhuǎn)/分以下轉(zhuǎn)速的電機(jī)大多采用CM游隙，如高溫高速電機(jī)則要求采用相對(duì)較大的游隙。INA軸承游隙在裝配后會(huì)因?yàn)閮?nèi)孔的漲大及外圓的縮小而導(dǎo)致減少，游隙的減少量=過(guò)盈量×6％（軸承室是鋁的除外）。比如INA軸承裝配前游隙是.1mm，裝配時(shí)過(guò)盈量為.1mm，則INA軸承裝配后的游隙為.4mm。在理論上INA軸承在零游隙時(shí)噪音和壽命都達(dá)到的狀態(tài)，但在實(shí)際運(yùn)轉(zhuǎn)中考慮到溫升等問(wèn)題，INA軸承在裝配后游隙為.2mm-.4mm較好。

IKO軸承斷裂失效主要原因是缺陷與過(guò)載兩大因素。當(dāng)外加載荷超過(guò)材料強(qiáng)度極限而造成零件斷裂稱為過(guò)載斷裂。過(guò)載原因主要是主機(jī)突發(fā)故障或安裝不當(dāng)。軸承零件的微裂紋、縮孔、氣泡、大塊外來(lái)雜物、過(guò)熱組織及局部燒傷等缺陷在沖擊過(guò)載或劇烈振動(dòng)時(shí)也會(huì)在缺陷處引起斷裂，稱為缺陷斷裂。應(yīng)當(dāng)指出，軸承在制造過(guò)程中，對(duì)原材料的入廠復(fù)驗(yàn)、鍛造和熱處理質(zhì)量控制、加工過(guò)程控制中可通過(guò)儀器正確分析上述缺陷是否存在，今后仍必須加強(qiáng)控制。
