直線(xian)傳動機構電(dian)(dian)動推桿英文名LinearActuator，又稱推桿電(dian)(dian)機、電(dian)(dian)動缸及線(xian)性(xing)致動器。電(dian)(dian)動推桿是(shi)一種(zhong)將電(dian)(dian)動機的(de)(de)旋轉(zhuan)運動轉(zhuan)變為推桿的(de)(de)直線(xian)往(wang)復(fu)運動的(de)(de)電(dian)(dian)力驅動裝(zhuang)置。

可(ke)用于各種(zhong)簡單或(huo)復雜(za)的(de)工(gong)藝(yi)流程中做(zuo)為執行機(ji)(ji)械使用，以(yi)實(shi)現遠距離(li)控(kong)制、集中控(kong)制或(huo)自動(dong)(dong)(dong)(dong)控(kong)制。直(zhi)線(xian)傳動(dong)(dong)(dong)(dong)機(ji)(ji)構(gou)電動(dong)(dong)(dong)(dong)推(tui)桿(gan)，直(zhi)線(xian)傳動(dong)(dong)(dong)(dong)機(ji)(ji)構(gou)電動(dong)(dong)(dong)(dong)推(tui)桿(gan)工(gong)作原(yuan)理電動(dong)(dong)(dong)(dong)機(ji)(ji)經齒輪減速(su)后，帶動(dong)(dong)(dong)(dong)一對絲桿(gan)螺母(mu)。把電機(ji)(ji)的(de)旋轉(zhuan)運動(dong)(dong)(dong)(dong)變成直(zhi)線(xian)運動(dong)(dong)(dong)(dong)，利(li)用電動(dong)(dong)(dong)(dong)機(ji)(ji)正(zheng)反轉(zhuan)完成推(tui)桿(gan)動(dong)(dong)(dong)(dong)作。如通過(guo)各種(zhong)杠(gang)桿(gan)、搖桿(gan)或(huo)連桿(gan)等機(ji)(ji)構(gou)可(ke)完成轉(zhuan)動(dong)(dong)(dong)(dong)、搖動(dong)(dong)(dong)(dong)等復雜(za)動(dong)(dong)(dong)(dong)作。通過(guo)改變杠(gang)桿(gan)力臂長度(du)，可(ke)以(yi)增(zeng)大或(huo)加大行程
