齒輪泵的分類
屬于結(jié)構(gòu)簡(jiǎn)單,納污能力強(qiáng),工作壓力相對(duì)較低,成本較低的一種, 廣泛用于農(nóng)業(yè)機(jī)械:拖拉機(jī)、收割機(jī)等。工程機(jī)械:叉車、自卸車等。
齒輪泵按照齒輪的嚙合形式可分為外嚙合式和內(nèi)嚙合式兩種,按照齒形曲線有漸開(kāi)線形、圓弧齒形和擺線齒形。
2)外嚙合齒輪泵
( 1 )外嚙合齒輪泵的結(jié)構(gòu)。主要由主動(dòng)齒輪、從動(dòng)齒輪、殼體、前后泵體、密封圈和軸承等組成。
外嚙合齒輪泵的結(jié)構(gòu)
1-從動(dòng)齒輪; 2-軸承套; 3-密封圈; 4一前端蓋; 5-密封;6-傳動(dòng)軸;;7-主動(dòng)齒輪;8- 殼體;9后端蓋
( 2 )外嚙合齒輪泵的工作原理
密封容腔由殼體、端蓋和兩對(duì)齒輪的嚙合部位組成。配流裝置由齒輪嚙合線將吸油區(qū)和壓油區(qū)隔開(kāi),起配流作用。
齒輪泵的主要優(yōu)點(diǎn)是結(jié)構(gòu)簡(jiǎn)單，體積小，質(zhì)量輕，工藝性好，價(jià)格便宜，自吸能力強(qiáng)，對(duì)油液污染不敏感，轉(zhuǎn)速范圍大，維護(hù)方便，工作可靠。它的缺點(diǎn)是困油現(xiàn)象嚴(yán)重，徑向不平衡力大，泄漏大，流量脈動(dòng)大，噪聲較高，不能做變量泵使用。低壓齒輪泵廣泛地應(yīng)用在低壓(25×105pa以下)的液壓系統(tǒng)中，如機(jī)床以及各種補(bǔ)泊、潤(rùn)滑和冷卻裝置等。齒輪泵在結(jié)構(gòu)上采取一定措施后，也可以達(dá)到較高的工作壓力。中壓齒輪泵主要應(yīng)用于機(jī)床、國(guó)軋鋼設(shè)備的液壓系統(tǒng)中。中高壓和高壓齒輪泵主要用于農(nóng)林機(jī)械工程機(jī)械、船舶機(jī)械和航空技術(shù)中。
和齒輪泵一樣，齒輪液壓馬達(dá)由于密封性差，容積效率較低，所以輸入的油壓不能過(guò)高，因而不能產(chǎn)生較大的轉(zhuǎn)矩，并且轉(zhuǎn)速和轉(zhuǎn)矩都是隨著齒輪嚙合情況而脈動(dòng)的。齒輪液壓馬達(dá)多用于高轉(zhuǎn)速低轉(zhuǎn)矩的液壓系統(tǒng)中。齒輪泵一般都可以直接作液壓馬達(dá)使用，即齒輪泵與齒輪液壓馬達(dá)二者是可逆的。
和齒輪泵相比，葉片泵有流量均勻、運(yùn)轉(zhuǎn)平穩(wěn)、噪聲小、壽命長(zhǎng)，輪廓尺寸較小、結(jié)構(gòu)較緊湊等優(yōu)點(diǎn)，但也存在著自吸能力差、調(diào)速范圍小、轉(zhuǎn)速較低、葉片容易咬死、工作可靠性較差、結(jié)構(gòu)較復(fù)雜、對(duì)油液污染較敏感等缺點(diǎn)。因此在工作環(huán)境較污穢、速度范圍變化較大的機(jī)械上應(yīng)用相對(duì)較少。在工作可靠性要求很高的地方，如飛機(jī)上，也很少應(yīng)用。葉片泵在中，低壓液壓系統(tǒng)尤其在機(jī)床行業(yè)中應(yīng)用*多。其中單作用式葉片泵常做變量泵使用，其額定壓力較低()，常用于組合機(jī)床，壓力機(jī)械等;雙作用式葉片泵只能做定量泵使用，其額定壓力可達(dá)14MPa~21MPa，在各類機(jī)床(尤其是精密機(jī)床)設(shè)備中，如注塑機(jī)、運(yùn)輸裝卸機(jī)械及工程機(jī)械等中壓系統(tǒng)中得到廣泛應(yīng)用。葉片液壓馬達(dá)*大的優(yōu)點(diǎn)是體積小、慣性小，動(dòng)作靈敏，允許換向頻率很高、甚至可在幾毫秒內(nèi)換向。但其*大的弱點(diǎn)是泄漏較大，機(jī)械特性較軟，不能在較低轉(zhuǎn)速下工作，調(diào)速范圍不能很大。因此適用于低轉(zhuǎn)矩，高轉(zhuǎn)速及對(duì)慣性要求較小，對(duì)機(jī)械特性要求不嚴(yán)的場(chǎng)合。由于變量葉片液壓馬達(dá)結(jié)構(gòu)較復(fù)雜，相對(duì)運(yùn)動(dòng)部件多、泄漏較大，容積效率低，機(jī)械特性軟及調(diào)節(jié)不便等原因，葉片液壓馬達(dá)一般都制成定量式的，即一般葉片液壓馬達(dá)都是雙作用式的定量液壓馬達(dá)。
柱塞泵(液壓馬達(dá))由于構(gòu)成密封工作腔的構(gòu)件一一柱塞和缸體內(nèi)孔均為圓柱表面，加工方便，容易得到較高的配合精度，密封性好，故容積效率高，工作壓力高。同時(shí)這種泵只要改變柱塞的行程就可以很方便的改變其流量，易于實(shí)現(xiàn)變量。因此柱塞泵在高壓、大流量、大功率的液壓系統(tǒng)中和流量需要調(diào)節(jié)的場(chǎng)合，如龍門刨床、拉床、液壓機(jī)、工程機(jī)械、礦山機(jī)械、船舶機(jī)械等場(chǎng)合得到廣泛應(yīng)用。

液壓是機(jī)械行業(yè)、機(jī)電行業(yè)的一個(gè)名詞。液壓可以用動(dòng)力傳動(dòng)方式， 成為液壓傳動(dòng)。液壓也可用作控制方式，稱為液壓控制。
液壓傳動(dòng)是以液體作為工作介質(zhì)，利用液體的壓力能來(lái)傳遞動(dòng)力。
液壓控制是以有壓力液體作為控制信號(hào)傳遞方式的控制。用液壓技術(shù)構(gòu)成的控制系統(tǒng)稱為液壓控制系統(tǒng)。液壓挖制通常包括液壓開(kāi)環(huán)挖制和液壓閉環(huán)控制。液壓閉環(huán)挖制也就是液壓伺服控制，它構(gòu)成液壓伺服系統(tǒng)，通常包括電氣液壓伺服系統(tǒng)(電液伺服系統(tǒng))和機(jī)械液壓同服系統(tǒng)(機(jī)液伺服系統(tǒng)，或機(jī)液伺服機(jī)構(gòu))等。
一個(gè)完整的液壓系統(tǒng)由五個(gè)部分組成，即能源裝置、執(zhí)行裝置、控制調(diào)節(jié)裝置、輔助裝置、液體介質(zhì)。液壓由于其傳遞動(dòng)力大，易于傳遞及配置等特點(diǎn)，在工業(yè)、民用行業(yè)應(yīng)用廣泛。液壓系統(tǒng)的執(zhí)行元件(液壓缸和液壓馬達(dá))的作用是將液體的壓力能轉(zhuǎn)換為機(jī)械能，從而獲
得需要的直線往復(fù)運(yùn)動(dòng)或回轉(zhuǎn)運(yùn)動(dòng)。液壓系統(tǒng)的能源裝置(液壓泵)的作用是將原動(dòng)機(jī)的機(jī)械能轉(zhuǎn)換成液體的壓力能。
液壓系統(tǒng)組成
一個(gè)完整的液壓系統(tǒng)由五個(gè)部分組成，即動(dòng)力元件、執(zhí)行元件、控制元件、輔助元件和工作介質(zhì)。
動(dòng)力元件的作用是將原動(dòng)機(jī)的機(jī)械能轉(zhuǎn)換成液體的壓力能。動(dòng)力元件指液壓系統(tǒng)中的液壓泵，它向整個(gè)液壓系統(tǒng)提供動(dòng)力。液壓泵的結(jié)構(gòu)形式一般有齒輪泵、葉片泵、柱塞泵、螺桿泵。
執(zhí)行元件的作用是將液體的壓力能轉(zhuǎn)換為機(jī)械能，驅(qū)動(dòng)負(fù)載作直線往復(fù)運(yùn)動(dòng)或回轉(zhuǎn)運(yùn)動(dòng)。執(zhí)行元件有液壓缸和液壓馬達(dá)。
挖制元件(即各種液壓閥)在液壓系統(tǒng)中控制和調(diào)節(jié)液體的壓力、流量和方向。
根據(jù)控制功能的不同，液壓閥可分為壓力控制閥、流量挖制閥和方向控制閥。壓力挖制閥又分為溢流閥(安全閥)、減壓閥、順序閥、壓力繼電器等:流量控制閥包括節(jié)流閥、調(diào)整閥、分流集流閥等:方向控制閥包括單向閥、液挖單向閥、梭閥、換向閥等。根據(jù)控制方式不同，
液壓閥可分為開(kāi)關(guān)式控制閥、定值控制閥和比例控制閥。
輔助元件包括蓄能器、過(guò)濾器、冷卻器、加熱器、油管、管接頭、油箱、壓力計(jì)、流量計(jì)、
密封裝置等，它們起連接、儲(chǔ)油、過(guò)濾和測(cè)量油液壓力等輔助作用
工作介質(zhì)是指各類液壓傳動(dòng)中的液壓油或乳化液，有各種礦物油、乳化液和合成型液壓油等
幾大類。液壓系統(tǒng)就是通過(guò)其實(shí)現(xiàn)運(yùn)動(dòng)和動(dòng)力傳遞的。
液壓元件可分為動(dòng)力元件和挖制元件以及執(zhí)行元件三大類。盡管都是液壓元件，它們的自身
功能和安裝使用的技術(shù)要求也不盡相同，現(xiàn)分別介紹如下:
動(dòng)力元件:指的是各種液壓泵，齒輪泵、葉片泵、柱塞泵、螺桿泵。
1、齒輪油泵和串聯(lián)泵(包括外嚙合與內(nèi)嚙合)兩種結(jié)構(gòu)型式。
2、葉片油泵(包括單級(jí)泵、變量泵、雙級(jí)泵、雙聯(lián)泵)。
3、柱塞油泵，又分為軸向柱塞油泵和徑向柱塞油泵，軸向柱塞泵有定量泵、變量泵、(變量泵又分為手動(dòng)變量與壓力補(bǔ)償變量、伺服變量等多種)從結(jié)構(gòu)上又分為端面配油和閥式配油兩種配油方式，而徑向柱塞泵的配油型式，基本上為閥式配油。);
執(zhí)行元件:液壓缸和液壓馬達(dá)，液壓缸有活塞液壓缸、柱塞液壓缸、擺動(dòng)液壓缸、組合液壓缸:液壓馬達(dá)有齒輪式液壓馬達(dá)、葉片液壓馬達(dá)、柱塞液壓馬達(dá):

輔助元件:除上述三部分以外的其它元件，包括壓力表、濾油器、蓄能裝置、冷卻器、管件{主要包括:各種管接頭 (擴(kuò)口式、 焊接式、卡套式，sae法蘭)、高壓球閥、快換接頭、軟管總成、測(cè)壓接頭、管夾等}及油箱等，它們同樣十分重要。
優(yōu)點(diǎn)
與機(jī)械傳動(dòng)、電氣傳動(dòng)相比，液壓傳動(dòng)具有以下優(yōu)點(diǎn):
1、液壓傳動(dòng)的各種元件，可以根據(jù)需要方便、靈活地來(lái)布置。
2、重量輕、體積小、運(yùn)動(dòng)慣性小、反應(yīng)速度快[2]
3、操縱控制方便，可實(shí)現(xiàn)大范圍的無(wú)級(jí)調(diào)速(調(diào)速范圍達(dá)2000: 1)。
4、可自動(dòng)實(shí)現(xiàn)過(guò)載保護(hù)。
5、一般采用礦物油作為工作介質(zhì)，相對(duì)運(yùn)動(dòng)面可自行潤(rùn)滑，使用壽命長(zhǎng)。
6、很容易實(shí)現(xiàn)直線運(yùn)動(dòng)。
7、很容易實(shí)現(xiàn)機(jī)器的自動(dòng)化，當(dāng)采用電液聯(lián)合控制后，不僅可實(shí)現(xiàn)更高程度的自動(dòng)控制過(guò)程，而且可以實(shí)現(xiàn)遙控。
