交流直線伺服電機(jī)直接驅(qū)動進(jìn)給技術(shù)已趨成熟。數(shù)控機(jī)床的進(jìn)給驅(qū)動有‘旋轉(zhuǎn)伺服電機(jī)精密高速滾珠絲杠’和‘直線電機(jī)直接驅(qū)動’兩種類型。傳統(tǒng)的滾珠絲杠工藝成熟加工精度較高,實現(xiàn)高速化的成本相對較低,所以目前應(yīng)用廣泛。使用滾,珠絲杠驅(qū)動的高速加工機(jī)床移動速度90m/min,加速度1.5g。但滾珠絲杠是機(jī)械傳動,機(jī)械元件間存在彈性變形、摩擦和反向間隙,相應(yīng)會造成運動滯后和非線性誤差,所以再進(jìn)一步提高滾珠絲杠副移動速度和加速度比較難了。90年代以來,高速高精的大型加工機(jī)床中,應(yīng)用直線電機(jī)直接驅(qū)動進(jìn)給驅(qū)動方式。它比滾珠絲杠驅(qū)動具有剛度更高、速度范圍更寬、加速特性更好、運動慣量更小、動態(tài)響應(yīng)性能更佳,運行更平穩(wěn)、位置精度更高等優(yōu)點。且直線電機(jī)直接驅(qū)動,不需中間機(jī)械傳動,減小了機(jī)械磨損與傳動誤差,減少了維護(hù)工作。直線電機(jī)直接驅(qū)動與滾珠絲杠傳動相比,其速度提高30倍,加速度提高10倍,達(dá)10g,剛度提高7倍,響應(yīng)頻率達(dá)100Hz,還有較大的發(fā)展余地。當(dāng)前,在高速高精加工機(jī)床領(lǐng)域中,兩種驅(qū)動方式還會并存相當(dāng)長一段時間,但從發(fā)展趨勢來看,直線電機(jī)驅(qū)動所占的比重會愈來愈大。種種跡象表明,直線電機(jī)驅(qū)動在高速高精加工機(jī)床上的應(yīng)用已進(jìn)入加速增長期。

一般常用的有溶劑清洗法、化學(xué)處理清潔法和機(jī)械清潔法。表面干燥清洗干凈后可用過濾的干燥壓縮空氣吹干,或者用12~17℃的干燥器進(jìn)行干燥,也可用干凈紗布擦干。涂敷防銹油的方法1)浸泡法:一些小軸承采用浸泡在防銹油脂中,讓其表面粘附上一層防銹油脂的方法。油膜厚度可通過控制防銹油脂的溫度或粘度來達(dá)到。刷涂法用于不適用浸泡或噴涂的室外建筑設(shè)備或特殊形狀的制品,刷涂時既要注意不產(chǎn)生堆積,也要注意防止漏涂。

交流伺服電機(jī)也是無刷電機(jī),分為同步和異步電機(jī),目前運動控制中一般都用同步電機(jī),它的功率范圍大,可以做到很大的功率。大慣量,轉(zhuǎn)動速度低,且隨著功率增大而快速降低。因而適合做低速平穩(wěn)運行的應(yīng)用。
6, 使用電機(jī)時要注意的問題?
上電運行前要作如下檢查:
1) 電源電壓是否合適(過壓很可能造成驅(qū)動模塊的損壞);對于直流輸入的 +/- 極性一定不能接錯,驅(qū)動控制器上的電機(jī)型號或電流設(shè)定值是否合適(開始時不要太大);
2) 控制信號線接牢靠,工業(yè)現(xiàn)場要考慮屏蔽問題(如采用雙絞線);
3) 不要開始時就把需要接的線全接上,只連成基本的系統(tǒng),運行良好后,再逐步連接。
4) 一定要搞清楚接地方法,還是采用浮空不接。
5) 開始運行的半小時內(nèi)要密切觀察電機(jī)的狀態(tài),如運動是否正常,聲音和溫升情況,發(fā)現(xiàn)問題立即停機(jī)調(diào)整。
