REXROTH油泵分類
力士樂油泵有三大類：力士樂柱塞泵，力士樂葉片泵，力士樂齒輪泵，REXROTH力士樂柱塞泵根據(jù)傾斜元件的不同，有斜盤式和斜軸式兩種。斜盤式是斜盤相對(duì)回轉(zhuǎn)的缸體有一傾斜角度，而引起柱塞在泵缸中往復(fù)運(yùn)動(dòng)。傳動(dòng)軸軸線和缸體軸線是*的。這種結(jié)構(gòu)較簡(jiǎn)單，轉(zhuǎn)速較高，但工作條件要求高，柱塞端部與斜盤的接觸部往往是薄弱環(huán)節(jié)，REXROTH葉片泵只不過是離心泵的一種具體應(yīng)用的泵而命名。實(shí)質(zhì)上砂泵只是一個(gè)籠統(tǒng)的叫法，力士樂齒輪泵是采用齒輪內(nèi)嚙合原理，內(nèi)外齒輪節(jié)圓緊靠一邊，另一邊被泵蓋上“月牙板”隔開。主軸上的主動(dòng)內(nèi)齒輪帶動(dòng)其中外齒輪同向轉(zhuǎn)動(dòng)，在進(jìn)口處齒輪相互分離形成負(fù)壓而吸入液體 。國(guó)力士樂柱塞泵A10VSO 45排量：A10VSO45DR/31R-PPA12N00 A10VSO45DR/31R-PPA12K01 A10VSO45DFR1/31R-PPA12N00 A10VSO45DFR1/31R-PPA12N00 A10VSO45DFR1/31R-PPA12K02 A10VSO45DFR/31R-PPA12N00 A10VSO45DFR/31R-PPA12K01 A10VSO45DFR/31R-PPA12K26 A10VSO45DFLR/31R-PPA12N00 A10VSO45DG/31R-PPA12N00 A10VSO45DRG/31R-PPA12N00 A10VSO45DFE1/31R-PPA12N00 A10VSO45FHD/31R-PPA12N00 A10VSO45ED/31R-PPA12N00

REXROTH柱塞泵：斜軸式的斜盤軸線與傳動(dòng)軸軸線是*的。它是由于柱塞缸體相對(duì)傳動(dòng)軸傾斜一角度而使柱塞作往復(fù)運(yùn)動(dòng)。流量調(diào)節(jié)依靠擺動(dòng)柱塞缸體的角度來實(shí)現(xiàn)，故有的又稱擺缸式。它與斜盤式相比，工作可靠，流量大，但結(jié)構(gòu)復(fù)雜。 軸向柱塞泵與徑向柱塞泵比較，排出壓力高，它一般可在20～50MPa范圍內(nèi)工作，效率也高，徑向尺寸小、結(jié)構(gòu)緊湊、體積小、重量輕。但結(jié)構(gòu)較徑向柱塞泵復(fù)雜，加工制造要求高，價(jià)格較貴。 為了提高效率，在應(yīng)軸向柱塞泵一般都由缸體、配油盤、柱塞和斜盤等主要零件組成。缸體內(nèi)有多個(gè)柱塞，柱塞是軸向排列的，即柱塞的中心線平行于傳動(dòng)軸的軸線，因此稱它為軸向柱塞泵。但它又不同于往復(fù)式柱塞泵，因?yàn)樗闹粌H在泵缸內(nèi)做往復(fù)運(yùn)動(dòng)，而且柱塞和泵缸與斜盤相對(duì)有旋轉(zhuǎn)運(yùn)動(dòng)。柱塞以一球形端頭與斜盤接觸。在配油盤上有高低壓月形溝槽，它們彼此由隔墻隔開，保證一定的密封性，它們分別與泵的進(jìn)油口和出油口連通。斜盤的軸線與缸體軸線之間有一傾斜角度。
