力士樂徑向柱塞泵

  德國rexroth徑向柱塞泵工作原理:驅(qū)動扭矩由驅(qū)動軸 通過十字聯(lián)軸器 傳遞給星形的液壓缸體轉(zhuǎn)子，定于不受其它橫向作用力。轉(zhuǎn)于裝在配流軸上。位于轉(zhuǎn)子中的徑向布置的柱塞，通過靜壓平衡的滑靴緊貼著偏心行程定子。柱塞與滑靴 球鉸相連，并通過卡簧鎖定。二個保持環(huán)將滑靴卡在行程定子上。

泵轉(zhuǎn)動時，它依靠離心力和液壓力壓在定于內(nèi)表面上。當(dāng)轉(zhuǎn)子轉(zhuǎn)動時，由于定于的偏心作用，柱塞將作往復(fù)運動，它的行程為定于偏心距的2倍。定子的偏心距可由泵體上的徑向位置相對的兩個柱塞來調(diào)節(jié)。

油液的進(jìn)出通過泵體和配流軸上的流道，并由配流軸上吸油口控制，泵體內(nèi)產(chǎn)生的液壓力被靜壓平衡的表面所吸收。摩擦副的靜壓平衡采取了過平衡壓力補償方法，形成了開環(huán)控制。支承驅(qū)動軸的軸承只起支承作用，不受其他外力的作用。

德國Rexroth的工作原理圖。這種泵由柱塞1、轉(zhuǎn)子2、襯套3、定子4和配油軸5組成。定子和轉(zhuǎn)子之間有一個偏心e。襯套3固定在轉(zhuǎn) 子孔內(nèi)隨之一起轉(zhuǎn)動。配油軸5是固定不動的。柱塞在轉(zhuǎn)子（缸體）的徑向孔內(nèi)運動，形成了泵的密封工作容腔。顯然，當(dāng)轉(zhuǎn)子按圖示方向轉(zhuǎn)動時，位于上半周的工 作容腔處于吸油狀態(tài)，油箱中的油液經(jīng)配油軸的a孔進(jìn)入b腔；位于下半周的工作容腔則處于壓油狀態(tài)，c腔中的油將從配油軸的d孔向外輸出。改變定子與轉(zhuǎn)子偏 心距e的大小和方向，就可以改變泵的輸出流量和泵的吸、壓油方向。因此徑向柱塞泵可以做成單向或雙向變量泵。
德國Rexroth的徑向尺寸大，自吸能力差，配油軸受徑向不平衡液壓力作用，易于磨損。這些原因限制了轉(zhuǎn)速和工作壓力的提高。
