  新聞:井阱礦區(qū)數(shù)控車床用步進(jìn)馬達(dá)28H45-0674A哪里有賣
　　交流直線伺服電機(jī)直接驅(qū)動(dòng)進(jìn)給技術(shù)已趨成熟。數(shù)控機(jī)床的進(jìn)給驅(qū)動(dòng)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(dòng)’兩種類型。傳統(tǒng)的滾珠絲杠工藝成熟加工精度較高，實(shí)現(xiàn)高速化的成本相對(duì)較低，所以目前應(yīng)用廣泛。使用滾，珠絲杠驅(qū)動(dòng)的高速加工機(jī)床移動(dòng)速度90m/min，加速度1.5g。但滾珠絲杠是機(jī)械傳動(dòng)，機(jī)械元件間存在彈性變形、摩擦和反向間隙，相應(yīng)會(huì)造成運(yùn)動(dòng)滯后和非線性誤差，所以再進(jìn)一步提高滾珠絲杠副移動(dòng)速度和加速度比較難了。90年代以來(lái)，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(dòng)進(jìn)給驅(qū)動(dòng)方式。它比滾珠絲杠驅(qū)動(dòng)具有剛度更高、速度范圍更寬、加速特性更好、運(yùn)動(dòng)慣量更小、動(dòng)態(tài)響應(yīng)性能更佳，運(yùn)行更平穩(wěn)、位置精度更高等優(yōu)點(diǎn)。且直線電機(jī)直接驅(qū)動(dòng)，不需中間機(jī)械傳動(dòng)，減小了機(jī)械磨損與傳動(dòng)誤差，減少了維護(hù)工作。直線電機(jī)直接驅(qū)動(dòng)與滾珠絲杠傳動(dòng)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(dòng)方式還會(huì)并存相當(dāng)長(zhǎng)一段時(shí)間，但從發(fā)展趨勢(shì)來(lái)看，直線電機(jī)驅(qū)動(dòng)所占的比重會(huì)愈來(lái)愈大。種種跡象表明，直線電機(jī)驅(qū)動(dòng)在高速高精加工機(jī)床上的應(yīng)用已進(jìn)入加速增長(zhǎng)期。
