推(tui)桿電(dian)(dian)機(ji)(ji)又名直(zhi)線(xian)驅動(dong)器，主要是(shi)由電(dian)(dian)機(ji)(ji)推(tui)桿和控(kong)制裝置等機(ji)(ji)構組成的一(yi)種新型直(zhi)線(xian)執行機(ji)(ji)構，可以(yi)認為是(shi)旋轉電(dian)(dian)機(ji)(ji)在結構方(fang)面(mian)的一(yi)種延伸。電(dian)(dian)動(dong)推(tui)桿是(shi)一(yi)種將電(dian)(dian)動(dong)機(ji)(ji)的旋轉運動(dong)轉變(bian)為推(tui)桿的直(zhi)線(xian)往復運動(dong)的電(dian)(dian)力驅動(dong)裝置。可用于各種簡單或(huo)復雜的工藝流程中(zhong)做(zuo)為執行機(ji)(ji)械使用，以(yi)提升遠距(ju)離控(kong)制、集中(zhong)控(kong)制或(huo)自動(dong)控(kong)制。

推桿電機原理：

電(dian)(dian)動(dong)(dong)(dong)(dong)機經齒輪(lun)或蝸(gua)輪(lun)蝸(gua)桿(gan)(gan)(gan)減速后，帶動(dong)(dong)(dong)(dong)一對(dui)絲桿(gan)(gan)(gan)螺(luo)母(mu)。把(ba)電(dian)(dian)機的旋轉運(yun)(yun)動(dong)(dong)(dong)(dong)變成(cheng)(cheng)直線運(yun)(yun)動(dong)(dong)(dong)(dong)，利用電(dian)(dian)動(dong)(dong)(dong)(dong)機正反(fan)轉完成(cheng)(cheng)推桿(gan)(gan)(gan)動(dong)(dong)(dong)(dong)作。如通過各種杠桿(gan)(gan)(gan)、搖桿(gan)(gan)(gan)或連桿(gan)(gan)(gan)等機構可完成(cheng)(cheng)轉動(dong)(dong)(dong)(dong)、搖動(dong)(dong)(dong)(dong)等復雜動(dong)(dong)(dong)(dong)作。通過改變杠桿(gan)(gan)(gan)力臂長度(du)，可以增大(da)或減小行程(cheng)。

蝸(gua)輪蝸(gua)桿(gan)驅動(dong)形式：電(dian)(dian)機(ji)齒輪上的蝸(gua)桿(gan)帶(dai)動(dong)蝸(gua)輪轉動(dong)，使蝸(gua)輪內的小絲桿(gan)作軸(zhou)向移動(dong)，由連(lian)接板帶(dai)動(dong)限(xian)位桿(gan)相(xiang)應作軸(zhou)向移動(dong)，至所需行程(cheng)時(shi)，通過(guo)調節限(xian)位塊壓下行程(cheng)開關斷(duan)電(dian)(dian)，電(dian)(dian)動(dong)機(ji)停止運轉（正反控制相(xiang)同）。

齒(chi)輪(lun)驅動(dong)(dong)形式：電機通過減速(su)齒(chi)輪(lun)后帶(dai)動(dong)(dong)安裝于(yu)內(nei)管的小絲桿，帶(dai)動(dong)(dong)與之(zhi)連接一起的做軸向(xiang)運(yun)行(xing)(xing)螺母，至所設定(ding)的行(xing)(xing)程時螺母觸(chu)角壓住限(xian)位(wei)開(kai)關斷開(kai)電源，電機停止(zhi)運(yun)動(dong)(dong)（反向(xiang)與之(zhi)相同）。
