液壓馬達是液壓系統(tǒng)的一種執(zhí)行元件，它將液壓泵提供的液體壓力能轉(zhuǎn)變?yōu)槠漭敵鲚S的機械能(轉(zhuǎn)矩和轉(zhuǎn)速)。液體是傳遞力和運動的介質(zhì)。液壓馬達，亦稱為油馬達，主要應(yīng)用于注塑機械、船舶、起揚機、工程機械、建筑機械、煤礦機械、礦山機械、冶金機械、船舶機械、石油化工、港口機械等。
折疊低速馬達
轉(zhuǎn)速低于500r/min的液壓馬達屬于低速液壓馬達。它的基本形式是徑向柱塞式。低速液壓馬達的主要特點是:排量大，體積大，轉(zhuǎn)速低，可以直接與工作機構(gòu)連接，不需要減速裝置，使傳動機構(gòu)大大簡化，低速液壓馬達的輸出扭矩較大，可達幾千到幾萬Nm，因此又稱為低速大扭矩液壓馬達。

軸向柱塞泵除閥式配流外，其它形式原則上都可以作為液壓馬達用，即軸向柱塞泵和軸向柱塞馬達是可逆的。軸向柱塞馬達的工作原理為，配油盤和斜盤固定不動，馬達軸與缸體相連接一起旋轉(zhuǎn)。當(dāng)壓力油經(jīng)配油盤的窗口進入缸體的柱塞孔時，柱塞在壓力油作用下外伸，緊貼斜盤，斜盤對柱塞產(chǎn)生一個法向反力p，此力可分解為軸向分力及和垂直分力Q。Q與柱塞上液壓力相平衡，而Q則使柱塞對缸體中心產(chǎn)生一個轉(zhuǎn)矩，帶動馬達軸逆時針方向旋轉(zhuǎn)。軸向柱塞馬達產(chǎn)生的瞬時總轉(zhuǎn)矩是脈動的。若改變馬達壓力油輸入方向，則馬達軸按順時針方向旋轉(zhuǎn)。斜盤傾角a的改變、即排量的變化，不僅影響馬達的轉(zhuǎn)矩，而且影響它的轉(zhuǎn)速和轉(zhuǎn)向。斜盤傾角越大，產(chǎn)生轉(zhuǎn)矩越大，轉(zhuǎn)速越低。4系列變量柱塞泵：

但是，由于液壓馬達和液壓泵的工作條件不同，對它們的性能要求也不一樣，所以同類型的液壓馬達和液壓泵之間，仍存在許多差別。首先液壓馬達應(yīng)能夠正、反轉(zhuǎn)，因而要求其內(nèi)部結(jié)構(gòu)對稱;液壓馬達的轉(zhuǎn)速范圍需要足夠大，特別對它的穩(wěn)定轉(zhuǎn)速有一定的要求。因此，它通常都采用滾動軸承或靜壓滑動軸承;其次液壓馬達由于在輸入壓力油條件下工作，因而不必具備自吸能力，但需要一定的初始密封性，才能提供必要的起動轉(zhuǎn)矩。由于存在著這些差別，使得液壓馬達和液壓泵在結(jié)構(gòu)上比較相似，但不能可逆工作。MR500F-F1N1N1S1NX0701/58323
