一、齒輪油泵的特點有哪些

齒輪油泵是通過一對參數和結構相同的漸開線齒輪的相互滾動嚙合,將油箱內的低壓油升至能做功的高壓油的重要部件。那么你知道齒輪油泵的特點有哪些嗎？

1、結構緊湊(cou)，使用(yong)和保養方便(bian)。

2、具有良好的(de)自吸性，故每次開泵前無須灌(guan)入(ru)液體。

3、齒輪油泵的(de)潤滑是靠輸送(song)的(de)液體而(er)自動達到(dao)的(de)，故日(ri)常工(gong)作時無須別加潤滑油。

二、齒輪油泵的作用是什么

齒輪油泵的(de)的(de)作(zuo)用是(shi)用來傳送(song)粘性(xing)比較大的(de)液(ye)(ye)態(tai)(tai)，如潤滑(hua)油(you)和燃燒油(you)，不(bu)適合傳送(song)粘性(xing)較低(di)的(de)液(ye)(ye)態(tai)(tai)例(li)如水以及(ji)汽油(you)等(deng)等(deng)，不(bu)適合傳送(song)帶有顆粒雜(za)質的(de)液(ye)(ye)態(tai)(tai)影(ying)響泵的(de)使用期限，可身為(wei)潤滑(hua)系(xi)統(tong)油(you)泵和液(ye)(ye)壓系(xi)統(tong)油(you)泵，普遍用于汽車(che)發動機(ji)、汽輪(lun)發電機(ji)、多級離心風機(ji)、數控車(che)床以及(ji)其他設備。齒輪(lun)油(you)泵加工(gong)工(gong)藝要求高，不(bu)容易獲得準(zhun)確的(de)匹(pi)配以及(ji)不(bu)影(ying)響環(huan)保。

當齒(chi)(chi)輪(lun)油(you)(you)泵積(ji)極主動(dong)(dong)傳(chuan)動(dong)(dong)齒(chi)(chi)輪(lun)旋轉，吸(xi)油(you)(you)腔(qiang)傳(chuan)動(dong)(dong)齒(chi)(chi)輪(lun)松脫嚙合，傳(chuan)動(dong)(dong)齒(chi)(chi)輪(lun)的(de)傳(chuan)動(dong)(dong)齒(chi)(chi)輪(lun)推出齒(chi)(chi)間，使密閉(bi)容積(ji)擴大，產生局(ju)部性真空，汽車油(you)(you)箱中(zhong)的(de)液壓(ya)油(you)(you)在外部大氣壓(ya)的(de)的(de)作用下(xia)，經吸(xi)輸(shu)油(you)(you)管(guan)路、吸(xi)油(you)(you)腔(qiang)進(jin)到(dao)齒(chi)(chi)間。伴(ban)隨著傳(chuan)動(dong)(dong)齒(chi)(chi)輪(lun)旋轉，吸(xi)入齒(chi)(chi)間的(de)液壓(ya)油(you)(you)被送到(dao)另一邊，進(jin)到(dao)壓(ya)油(you)(you)腔(qiang)。

這也是傳動齒輪進(jin)到嚙(nie)合(he)(he)，使密閉(bi)性漸漸縮減(jian)，傳(chuan)動(dong)(dong)(dong)(dong)齒(chi)輪(lun)間部份(fen)的(de)(de)液壓(ya)油(you)(you)(you)被擠出來(lai)，產生了傳(chuan)動(dong)(dong)(dong)(dong)齒(chi)輪(lun)的(de)(de)壓(ya)油(you)(you)(you)全過(guo)程。齒(chi)輪(lun)嚙(nie)合(he)(he)時齒(chi)向接觸線(xian)把吸油(you)(you)(you)腔(qiang)和(he)壓(ya)油(you)(you)(you)腔(qiang)分開(kai)，起配(pei)油(you)(you)(you)的(de)(de)作用。當齒(chi)輪(lun)油(you)(you)(you)泵的(de)(de)積(ji)極(ji)主動(dong)(dong)(dong)(dong)傳(chuan)動(dong)(dong)(dong)(dong)齒(chi)輪(lun)有電動(dong)(dong)(dong)(dong)機帶(dai)動(dong)(dong)(dong)(dong)連(lian)續(xu)不斷旋轉時，傳(chuan)動(dong)(dong)(dong)(dong)齒(chi)輪(lun)松脫(tuo)嚙(nie)合(he)(he)一邊，因為密閉(bi)容積(ji)增大，則連(lian)續(xu)不斷從汽車油(you)(you)(you)箱中吸油(you)(you)(you)，傳(chuan)動(dong)(dong)(dong)(dong)齒(chi)輪(lun)進(jin)到嚙(nie)合(he)(he)的(de)(de)一邊，因為密閉(bi)容積(ji)縮減(jian)則不斷排油(you)(you)(you)，產生一個連(lian)續(xu)不斷循環的(de)(de)全過(guo)程。

齒輪油(you)泵(beng)(beng)在泵(beng)(beng)殼中(zhong)配有一(yi)對旋(xuan)轉傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)齒輪，一(yi)個(ge)積(ji)極主動(dong)(dong)(dong)，一(yi)個(ge)處(chu)于被(bei)(bei)動(dong)(dong)(dong)，依靠兩(liang)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)齒輪的(de)互相嚙合，把泵(beng)(beng)內的(de)整體工作腔(qiang)分2個(ge)獨立的(de)部(bu)份。A為(wei)吸入腔(qiang)，B為(wei)排(pai)出(chu)來(lai)腔(qiang)。齒輪油(you)泵(beng)(beng)在運(yun)行時(shi)積(ji)極主動(dong)(dong)(dong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)齒輪帶動(dong)(dong)(dong)處(chu)于被(bei)(bei)動(dong)(dong)(dong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)齒輪旋(xuan)轉，當傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)齒輪從(cong)嚙合到松脫時(shi)在吸入側A就產生局部(bu)性(xing)真空(kong)，液(ye)態(tai)(tai)被(bei)(bei)吸入。被(bei)(bei)吸入的(de)液(ye)態(tai)(tai)充(chong)滿傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)齒輪的(de)各個(ge)齒谷而(er)送到排(pai)出(chu)來(lai)側B，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)齒輪進到嚙合時(shi)液(ye)態(tai)(tai)被(bei)(bei)擠出(chu)來(lai)，產生高(gao)壓液(ye)態(tai)(tai)并經(jing)泵(beng)(beng)排(pai)出(chu)口(kou)排(pai)出(chu)來(lai)泵(beng)(beng)外。
