液壓馬達(dá)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(jī)械能(轉(zhuǎn)矩和轉(zhuǎn)速)。液體是傳遞力和運(yùn)動的介質(zhì)。液壓馬達(dá)，亦稱為油馬達(dá)，主要應(yīng)用于注塑機(jī)械、船舶、起揚(yáng)機(jī)、工程機(jī)械、建筑機(jī)械、煤礦機(jī)械、礦山機(jī)械、冶金機(jī)械、船舶機(jī)械、石油化工、港口機(jī)械等。
工作原理，當(dāng)壓力油經(jīng)固定的配油軸4的窗口進(jìn)入缸體內(nèi)柱塞的底部時，柱塞向外伸出，緊緊頂住定子的內(nèi)壁，由于定子與缸體存在一偏心距。在柱塞與定子接觸處，定子對柱塞的反作用力為 。力可分解為和 兩個分力。當(dāng)作用在柱塞底部的油液壓力為p，柱塞直徑為d，力和之間的夾角為X時，力對缸體產(chǎn)生一轉(zhuǎn)矩，使缸體旋轉(zhuǎn)。缸體再通過端面連接的傳動軸向外輸出轉(zhuǎn)矩和轉(zhuǎn)速。以析的一個柱塞產(chǎn)生轉(zhuǎn)矩的情況，由于在壓油區(qū)作用有好幾個柱塞，在這些柱塞上所產(chǎn)生的轉(zhuǎn)矩都使缸體旋轉(zhuǎn)，并輸出轉(zhuǎn)矩。徑向柱塞液壓馬達(dá)多用于低速大轉(zhuǎn)矩的情況下。E-A4VS0180DR/30R-PPB13N00

但是，由于液壓馬達(dá)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(dá)和液壓泵之間，仍存在許多差別。首先液壓馬達(dá)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(dá)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(dá)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(dá)和液壓泵在結(jié)構(gòu)上比較相似，但不能可逆工作。MR500F-F1N1N1S1NX0701/58323

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(dá)用，即軸向柱塞泵和軸向柱塞馬達(dá)是可逆的。軸向柱塞馬達(dá)的工作原理為，配油盤和斜盤固定不動，馬達(dá)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(jìn)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(dá)軸逆時針方向旋轉(zhuǎn)。軸向柱塞馬達(dá)產(chǎn)生的瞬時總轉(zhuǎn)矩是脈動的。若改變馬達(dá)壓力油輸入方向，則馬達(dá)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(dá)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：

CALZONI、CALZONI馬達(dá)、CALZONI電機(jī)、 CALZONI液壓馬達(dá)、CALZONI徑向柱塞液壓馬達(dá)
意大利CALZONI國內(nèi)一級代理商
低價供應(yīng)意大利CALZONI馬達(dá)、CALZONI電機(jī)、 CALZONI液壓馬達(dá)、CALZONI徑向柱塞液壓馬達(dá)。意大利Calzoni馬達(dá)的杰出性能歸功于其特、具有技術(shù)的設(shè)計(jì)。其原理是通過具有一定壓力的容腔液壓油（A）將力從柱塞傳遞到旋轉(zhuǎn)軸 (2)上，而不是向傳統(tǒng)馬達(dá)那樣通過桿、活塞、墊片及頂針連接的。壓力油是在伸縮油缸(1)中，通過活塞與缸蓋間的球面副、缸蓋（4）與旋轉(zhuǎn)軸之間的球面副（3）進(jìn)行密封。通過選用材料與優(yōu)化設(shè)計(jì)減少摩擦及泄漏。設(shè)計(jì)的另一個優(yōu)點(diǎn)是取消了連接的部件，油缸僅能線性伸縮，因此作用力沒有橫向分量。這意味著運(yùn)動部件沒有橢圓磨損，油缸的連接處也沒有側(cè)向力。一系列的新穎設(shè)計(jì)對于馬達(dá)重量的減少與外形尺寸的優(yōu)化具有重要的意義，特別是相對于相同排量的傳統(tǒng)液壓馬達(dá)來說，優(yōu)勢明顯。系統(tǒng)時序是通過旋轉(zhuǎn)閥（5）來實(shí)現(xiàn)的，閥通過連接在旋轉(zhuǎn)軸上的旋轉(zhuǎn)閥驅(qū)動軸（8）驅(qū)動。旋轉(zhuǎn)閥在旋轉(zhuǎn)閥芯（6）與固定在馬達(dá)殼體上的反應(yīng)環(huán)（7）之間旋轉(zhuǎn)。系統(tǒng)時序也是設(shè)計(jì)，可以達(dá)到壓力平衡及溫度的自補(bǔ)償。此閥的優(yōu)點(diǎn)是具有革命性的油缸排列，實(shí)現(xiàn)極高的機(jī)械與容積效率。扭矩輸出即使在低速下也是相當(dāng)平穩(wěn)，即使在負(fù)載下馬達(dá)也表現(xiàn)出高性能的啟動特性。CALZONI 液壓馬達(dá)MRCN、 MRC、MR系列。意大利CALZONI主要產(chǎn)品包括：馬達(dá)、CALZONI液壓馬達(dá)、
