力士乐Rexroth油泵概述
力士乐Rexroth油泵是液压系统的动力机构，它将原动机（电动机、内燃机等）的机械能转变为液体的压力能。
力士乐油泵可以分为容积式和非容积室（蜗轮式）两种。
非容积式有离心泵、轴流泵等，利用高速旋转的叶轮使进口产生真空吸入液体，并在出口连续输出压力液体。这种泵进口与出口相通，效率随液体粘度增加而降低，并且输出液体量随出口压力升高而显著减少。   
容积式泵是通过一个封闭的空间容积的变化来实现吸油和压油的。当这个封闭容积由小变大时进行吸油，由大变小时进行压油。典型的为力士乐柱塞泵，柱塞从缸孔中拉出时吸油，压进时压油。这种泵进口与出口是被隔开的，效率取决于隔开吸压油腔的各对运动零件间的结构工艺间隙及油液的粘度等。粘度越高效率越高，输油量几乎保持不变（因效率略有影响，另外压力升高至18MPa，油液会被压缩1%）。

博世力士乐Rexroth生产先进的工业液压元件与系统，配合了微电子技术，令传动有力而精确。其电子传动与控制产品及系统永远走在科技前端
力士乐Rexroth柱塞泵根据倾斜元件的不同，有斜盘式和斜轴式两种。斜盘式是斜盘相对回转的缸体有一倾斜角度，而引起柱塞在泵缸中往复运动。传动轴轴线和缸体轴线是一致的。这种结构较简单，转速较高，但工作条件要求高，柱塞端部与斜盘的接触部往往是薄弱环节。斜轴式的斜盘轴线与传动轴轴线是一致的。它是由于柱塞缸体相对传动轴倾斜一角度而使柱塞作往复运动。流量调节依靠摆动柱塞缸体的角度来实现，故有的又称摆缸式。它与斜盘式相比，工作可靠，流量大，但结构复杂。
轴向柱塞泵与径向柱塞泵比较，排出压力高，它一般可在20～50MPa范围内工作，效率也高，径向尺寸小、结构紧凑、体积小、重量轻。但结构较径向柱塞泵复杂，加工制造要求高，价格较贵。
力士乐Rexroth轴向柱塞泵一般用于机床、冶金、锻压、矿山及起重机械的液压传动系统中，特别广泛地应用于大功率的液压传动系统中。为了提高效率，在应轴向柱塞泵一般都由缸体、配油盘、柱塞和斜盘等主要零件组成。缸体内有多个柱塞，柱塞是轴向排列的，即柱塞的中心线平行于传动轴的轴线，因此称它为轴向柱塞泵。但它又不同于往复式柱塞泵，因为它的柱塞不仅在泵缸内做往复运动，而且柱塞和泵缸与斜盘相对有旋转运动。柱塞以一球形端头与斜盘接触。在配油盘上有高低压月形沟槽，它们彼此由隔墙隔开，保证一定的密封性，它们分别与泵的进油口和出油口连通。斜盘的轴线与缸体轴线之间有一倾斜角度。
