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(dòng)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。
齒輪馬達(dá)
齒輪馬達(dá)在結(jié)構(gòu)上為了適應(yīng)正反轉(zhuǎn)要求，進(jìn)出油口相等、具有對(duì)稱性、有單外泄油口，將軸承部分的泄漏油引出殼體外;為了減少啟動(dòng)摩擦力矩，采用滾動(dòng)軸承;為了減少轉(zhuǎn)矩脈動(dòng)，齒輪液壓馬達(dá)的齒數(shù)比泵的齒數(shù)要多。
齒輪液壓馬達(dá)由干密封性差、容積效率較低、輸入油壓力不能過(guò)高、不能產(chǎn)生較大轉(zhuǎn)矩。并且瞬間轉(zhuǎn)速和轉(zhuǎn)矩隨著嚙合點(diǎn)的位置變化而變化，因此齒輪液壓馬達(dá)僅適合于高速小轉(zhuǎn)矩的場(chǎng)合。一般用于工程機(jī)械、農(nóng)業(yè)機(jī)械以及對(duì)轉(zhuǎn)矩均勻性要求不高的機(jī)械設(shè)備上。

但是，由于液壓馬達(dá)和液壓泵的工作條件不同，對(duì)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(duì)稱;液壓馬達(dá)的轉(zhuǎn)速范圍需要足夠大，特別對(duì)它的穩(wěn)定轉(zhuǎn)速有一定的要求。因此，它通常都采用滾動(dòng)軸承或靜壓滑動(dòng)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(dòng)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

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(guó)內(nèi)一級(jí)代理商
低價(jià)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、具有專利技術(shù)的設(shè)計(jì)。其原理是通過(guò)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(guò)桿、活塞、墊片及頂針連接的。壓力油是在伸縮油缸(1)中，通過(guò)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(guò)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(gè)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(méi)有橫向分量。這意味著運(yùn)動(dòng)部件沒(méi)有橢圓磨損，油缸的連接處也沒(méi)有側(cè)向力。一系列的新穎設(shè)計(jì)對(duì)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(duì)于相同排量的傳統(tǒng)液壓馬達(dá)來(lái)說(shuō)，優(yōu)勢(shì)明顯。系統(tǒng)時(shí)序是通過(guò)旋轉(zhuǎn)閥（5）來(lái)實(shí)現(xiàn)的，閥通過(guò)連接在旋轉(zhuǎn)軸上的旋轉(zhuǎn)閥驅(qū)動(dòng)軸（8）驅(qū)動(dòng)。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(shí)序也是專利設(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(dòng)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)、
