活塞式液壓缸
單活塞桿(gan)液(ye)壓(ya)缸只有一端(duan)有活塞桿(gan)。如(ru)圖所(suo)示(shi)是一種單活塞液(ye)壓(ya)缸。其兩端(duan)進出(chu)口油口A和B都可通壓(ya)力油或回(hui)油，以實現雙(shuang)向運動，故稱為(wei)雙(shuang)作用缸。
活塞僅(jin)能單向運動，其反方向運動需由(you)外(wai)力(li)來完(wan)成。但其行程一般較活塞式液壓缸(gang)大。
活塞式液壓缸(gang)(gang)可分為單桿(gan)式和雙桿(gan)式兩種結構，其固(gu)(gu)定方式由缸(gang)(gang)體固(gu)(gu)定和活塞桿(gan)固(gu)(gu)定兩種。、
擺動式液壓缸
擺動(dong)(dong)(dong)(dong)(dong)式(shi)(shi)(shi)液壓缸(gang)是(shi)輸出扭矩并實現(xian)往復(fu)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)(de)執行元件，有單(dan)葉片(pian)(pian)、雙(shuang)葉片(pian)(pian)、螺(luo)(luo)旋(xuan)(xuan)(xuan)擺動(dong)(dong)(dong)(dong)(dong)等幾種(zhong)形式(shi)(shi)(shi)。葉片(pian)(pian)式(shi)(shi)(shi)式(shi)(shi)(shi)：定子塊(kuai)固定在缸(gang)體上，而葉片(pian)(pian)和(he)轉子連接在一起。根據進油(you)方向，葉片(pian)(pian)將帶動(dong)(dong)(dong)(dong)(dong)轉子作往復(fu)擺動(dong)(dong)(dong)(dong)(dong)。螺(luo)(luo)旋(xuan)(xuan)(xuan)擺動(dong)(dong)(dong)(dong)(dong)式(shi)(shi)(shi)又分(fen)單(dan)螺(luo)(luo)旋(xuan)(xuan)(xuan)擺動(dong)(dong)(dong)(dong)(dong)和(he)雙(shuang)螺(luo)(luo)旋(xuan)(xuan)(xuan)兩種(zhong)，現(xian)在雙(shuang)螺(luo)(luo)旋(xuan)(xuan)(xuan)比(bi)較常用(yong)，靠兩個螺(luo)(luo)旋(xuan)(xuan)(xuan)副降液壓缸(gang)內活塞的(de)(de)直線運(yun)動(dong)(dong)(dong)(dong)(dong)轉變為直線運(yun)動(dong)(dong)(dong)(dong)(dong)與(yu)自轉運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)(de)復(fu)he運(yun)動(dong)(dong)(dong)(dong)(dong)，從而實現(xian)擺動(dong)(dong)(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)(dong)(dong)。
O形(xing)密(mi)(mi)(mi)封(feng)(feng)圈(quan)在低壓(ya)下使用時，與U形(xing)密(mi)(mi)(mi)封(feng)(feng)圈(quan)比較(jiao)(jiao)，由(you)于面壓(ya)較(jiao)(jiao)高(gao)、動(dong)靜(jing)摩(mo)擦阻(zu)力(li)之(zhi)差較(jiao)(jiao)大(da)，容(rong)易產生滑移(yi)或爬行；U型密(mi)(mi)(mi)封(feng)(feng)圈(quan)的面壓(ya)隨著壓(ya)力(li)的提高(gao)而增(zeng)(zeng)大(da)，雖然密(mi)(mi)(mi)封(feng)(feng)效(xiao)果(guo)也相應提高(gao)，但(dan)動(dong)靜(jing)摩(mo)擦阻(zu)力(li)之(zhi)差也變大(da)，內壓(ya)增(zeng)(zeng)加，影響(xiang)橡膠(jiao)彈性(xing)，由(you)于唇緣的接觸阻(zu)力(li)增(zeng)(zeng)大(da)，密(mi)(mi)(mi)封(feng)(feng)圈(quan)將會傾(qing)(qing)翻及唇緣伸長，也容(rong)易引(yin)起(qi)滑移(yi)或爬行，為防(fang)止其傾(qing)(qing)翻可采用支承(cheng)環(huan)保持其穩(wen)定。
