美國派克 parker擺線液壓馬達(dá)的特點(diǎn)及分類
從能量轉(zhuǎn)換的觀點(diǎn)來看,液壓馬達(dá)是將輸入的液壓能轉(zhuǎn)換為了機(jī)械能,而液壓泵正好相反,所以液壓泵與液壓
達(dá)是可逆工作的液壓元件,向任何一種液壓泵輸入工作液體,都可使其變成液壓馬達(dá)工況;反之,當(dāng)液壓馬達(dá)的
軸由外力矩驅(qū)動(dòng)旋轉(zhuǎn)時(shí),也可變?yōu)橐簤罕霉r。因?yàn)樗鼈兙哂型瑯拥幕窘Y(jié)構(gòu)要素--密閉而又可以周期變化的容
積和相應(yīng)的配油機(jī)構(gòu)。
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、反兩個(gè)方向旋轉(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)它的低穩(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)扭矩
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。
液壓馬達(dá)按其結(jié)構(gòu)類型來分可以分為齒輪式、葉片式、柱塞式等型式。按液壓馬達(dá)的額定轉(zhuǎn)速分為高速和低速
兩大類。額定轉(zhuǎn)速高于500r/min的屬于高速液壓馬達(dá),額定轉(zhuǎn)速低于500r/min的屬于低速液壓馬達(dá)。高速液壓
馬達(dá)的基本型式有齒輪式、螺杄式、葉片式和軸向柱塞式等。它們的主要特點(diǎn)是轉(zhuǎn)速較高、轉(zhuǎn)動(dòng)慣量小,便于啟動(dòng)
和制動(dòng),調(diào)節(jié)(調(diào)速及換向)靈敏庋高。通常高速液壓馬達(dá)輸出轉(zhuǎn)矩不大(僅幾十Nm到幾百Nm),所以又稱為高速小
扭矩液壓馬達(dá)。低速液壓馬達(dá)的基本型式是徑向柱塞式和擺線式,低速液壓馬達(dá)的主要特點(diǎn)是排量大、轉(zhuǎn)速低,因
此可直接與工作機(jī)構(gòu)連接,不需要減速裝置,使傳動(dòng)機(jī)構(gòu)大為簡化,通常低速液壓馬達(dá)輸出轉(zhuǎn)矩較大(可達(dá)幾千
Nm),所以又稱為低速大扭矩液壓馬達(dá)
美國派克 parker擺線液壓馬達(dá)的工作原理
擺線液壓馬
以的原理(少齒差原理)制成的內(nèi)嚙合擺線齒輪液壓馬達(dá),簡稱擺線
如圖,轉(zhuǎn)子與定子是一對(duì)擺線針齒嚙合副,轉(zhuǎn)子具有zi(zi=6或8)個(gè)齒的短幅外擺線等距線齒形,定子具有
Zⅰ+1個(gè)圓弧針齒齒形,轉(zhuǎn)子和定子形成Z+1個(gè)封閉齒間容積。其中一半處于高壓區(qū),一半處于低壓區(qū)。定子固定不
動(dòng),其齒圈中心為02,轉(zhuǎn)子的中心為O。轉(zhuǎn)子在壓力油作用下產(chǎn)生的液壓力矩以偏心距g為半徑繞定子中心02作
星運(yùn)動(dòng),即轉(zhuǎn)子一方面在繞自身的中心O自轉(zhuǎn)的同時(shí),另一方面其中心O又繞定子中心02反向公轉(zhuǎn),轉(zhuǎn)子在沿定子
滾動(dòng)時(shí),其進(jìn)回油腔不斷地改變,但始終以連心線oⅰ02為界分成兩邊,—邊為進(jìn)油,容腔容積逐漸増大;另-—邊排
油,容積逐漸縮小,將油液擠岀,通過配油機(jī)構(gòu),再經(jīng)油馬達(dá)出油口排往油箱
