詳細(xì)介紹
香港rexroth力士樂齒輪泵 在rexroth力士樂齒輪泵中,油液作用在輪外緣的壓力是不均勻的,從低壓腔到高壓腔,壓力沿齒輪旋轉(zhuǎn)的方向逐齒遞增,因此,齒輪和軸受到徑向不平衡力的作用,工作壓力越高,徑向不平衡力越大,徑向不平衡力很大時(shí),能使泵軸彎曲,導(dǎo)致齒頂壓向定子的低壓端,使定子偏磨,同時(shí)也加速軸承的磨損,降低軸承使用壽命。為了減小徑向不平衡力的影響,常采取縮小壓油口的辦法,使壓油腔的壓力僅作用在一個(gè)齒到兩個(gè)齒的范圍內(nèi),同時(shí),適當(dāng)增大徑向間隙,使齒頂不與定子內(nèi)表面產(chǎn)生金屬接觸,并在支撐上多采用滾針軸承或滑動(dòng)軸承。AZPNF-11-032/008RDC720KB-S0023

rexroth力士樂齒輪泵體內(nèi)相互嚙合的主、從動(dòng)齒輪2和3與兩端蓋及泵體一起構(gòu)成密封工作容積,齒輪的嚙合點(diǎn)將左、右兩腔隔開,形成了吸、壓油腔,當(dāng)齒輪按圖示方向旋轉(zhuǎn)時(shí),右側(cè)吸油腔內(nèi)的輪齒脫離嚙合,密封工作腔容積不斷增大,形成部分真空,油液在大氣壓力作用下從油箱經(jīng)吸油管進(jìn)入吸油腔,并被旋轉(zhuǎn)的輪齒帶入左側(cè)的壓油腔。左側(cè)壓油腔內(nèi)的輪齒不斷進(jìn)入嚙合,使密封工作腔容積減小,油液受到擠壓被排往系統(tǒng),這就是齒輪泵的吸油和壓油過程。在齒輪泵的嚙合過程中,嚙合點(diǎn)沿嚙合線,把吸油區(qū)和壓油區(qū)分開
