擺動式液壓缸
擺動(dong)式(shi)(shi)液壓(ya)缸(gang)是輸出扭矩并(bing)實(shi)現往復運(yun)動(dong)的(de)執行元件，有單葉片(pian)、雙葉片(pian)、螺(luo)(luo)旋(xuan)(xuan)(xuan)(xuan)擺動(dong)等幾種(zhong)形式(shi)(shi)。葉片(pian)式(shi)(shi)式(shi)(shi)：定子(zi)塊(kuai)固定在缸(gang)體上，而葉片(pian)和轉(zhuan)(zhuan)子(zi)連接在一(yi)起(qi)。根據進油方向，葉片(pian)將帶動(dong)轉(zhuan)(zhuan)子(zi)作往復擺動(dong)。螺(luo)(luo)旋(xuan)(xuan)(xuan)(xuan)擺動(dong)式(shi)(shi)又分(fen)單螺(luo)(luo)旋(xuan)(xuan)(xuan)(xuan)擺動(dong)和雙螺(luo)(luo)旋(xuan)(xuan)(xuan)(xuan)兩(liang)(liang)種(zhong)，現在雙螺(luo)(luo)旋(xuan)(xuan)(xuan)(xuan)比較(jiao)常用，靠兩(liang)(liang)個(ge)螺(luo)(luo)旋(xuan)(xuan)(xuan)(xuan)副降液壓(ya)缸(gang)內活塞的(de)直(zhi)線運(yun)動(dong)轉(zhuan)(zhuan)變(bian)為直(zhi)線運(yun)動(dong)與自轉(zhuan)(zhuan)運(yun)動(dong)的(de)復he運(yun)動(dong)，從而實(shi)現擺動(dong)運(yun)動(dong)。
零(ling)部件(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)精度(du)(du)的(de)(de)(de)影響問題，在(zai)液壓(ya)(ya)缸(gang)的(de)(de)(de)制造過程(cheng)中應(ying)嚴格控制缸(gang)體內(nei)(nei)壁和活(huo)塞桿表面加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)精度(du)(du)，特別是幾何精度(du)(du)，尤其直(zhi)(zhi)線(xian)(xian)(xian)度(du)(du)是關鍵，在(zai)國(guo)(guo)內(nei)(nei)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)藝中，活(huo)塞桿表面的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)基本上是車后磨削，保證直(zhi)(zhi)線(xian)(xian)(xian)度(du)(du)問題不(bu)(bu)大(da)，但對于缸(gang)體內(nei)(nei)壁的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)，其加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)方(fang)法很多(duo)，有鏜(tang)(tang)(tang)削-滾(gun)壓(ya)(ya)、鏜(tang)(tang)(tang)削-珩(heng)(heng)磨、直(zhi)(zhi)接(jie)珩(heng)(heng)磨等(deng)，但由(you)于國(guo)(guo)內(nei)(nei)材(cai)料的(de)(de)(de)基礎水(shui)平較國(guo)(guo)外有差距，管材(cai)坯料直(zhi)(zhi)線(xian)(xian)(xian)度(du)(du)差，壁厚不(bu)(bu)均勻(yun)、硬度(du)(du)不(bu)(bu)均勻(yun)等(deng)因(yin)素，往往直(zhi)(zhi)接(jie)影響缸(gang)體內(nei)(nei)壁加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)后的(de)(de)(de)直(zhi)(zhi)線(xian)(xian)(xian)度(du)(du)，因(yin)此建(jian)議采用鏜(tang)(tang)(tang)削-滾(gun)壓(ya)(ya)、鏜(tang)(tang)(tang)削-珩(heng)(heng)磨工(gong)(gong)(gong)(gong)(gong)藝，如直(zhi)(zhi)接(jie)珩(heng)(heng)磨，則必須首(shou)先提高管材(cai)坯料的(de)(de)(de)直(zhi)(zhi)線(xian)(xian)(xian)度(du)(du)。

在允許的(de)情況下，液壓(ya)(ya)缸(gang)的(de)缸(gang)體(ti)壁厚安全系數(shu)盡量選大一些，使缸(gang)體(ti)厚壁增加(jia)，特別是高壓(ya)(ya)工況下使用(yong)的(de)油缸(gang)，以減小油壓(ya)(ya)下的(de)缸(gang)體(ti)變(bian)形(xing)，變(bian)形(xing)后的(de)缸(gang)體(ti)也(ye)會引(yin)起液壓(ya)(ya)缸(gang)低速爬行。
①缸體組件
缸(gang)(gang)體組件由液(ye)壓缸(gang)(gang)缸(gang)(gang)筒與(yu)端蓋(gai)組成,缸(gang)(gang)筒與(yu)端蓋(gai)有多種(zhong)聯接形式.
②活塞組件
活(huo)(huo)塞(sai)組(zu)件由活(huo)(huo)塞(sai)與(yu)活(huo)(huo)塞(sai)桿構(gou)成,活(huo)(huo)塞(sai)和活(huo)(huo)塞(sai)桿除常用的螺(luo)(luo)紋聯接外,也可采用'非螺(luo)(luo)紋式'聯接. ③密封裝(zhuang)置
在活塞和(he)活塞桿的(de)(de)運動部分,端(duan)蓋和(he)缸(gang)筒間的(de)(de)靜止(zhi)部分等(deng)處都需要(yao)設置可靠的(de)(de)密封.密封是(shi)提高系統(tong)性能與效率的(de)(de)有效措(cuo)施.
④緩沖裝置
大型(xing),高速及精度的液壓缸(gang)應設有(you)緩(huan)沖(chong)裝置(zhi)(zhi),常見的液壓缸(gang)緩(huan)沖(chong)裝置(zhi)(zhi)有(you)環狀間隙式(shi)(shi),節流口可調(diao)式(shi)(shi)和節流口可變式(shi)(shi)等(deng)幾種.
⑤排氣裝置
液(ye)壓(ya)缸中存在空氣將使其運動不平穩(wen),當壓(ya)力增大(da)時會產生絕熱壓(ya)縮而造成局部(bu)高溫,因(yin)此應在液(ye)壓(ya)缸的高部(bu)位上設(she)置排(pai)氣裝置.
排(pai)氣裝置通(tong)常有珠形閥(fa)式(shi)排(pai)氣閥(fa)和錐形閥(fa)式(shi)排(pai)氣閥(fa)兩(liang)種(zhong)形式(shi).
