擺動式液壓缸
擺(bai)動(dong)(dong)(dong)(dong)式(shi)(shi)液(ye)壓缸(gang)是(shi)輸出扭(niu)矩并實(shi)現(xian)往復運(yun)動(dong)(dong)(dong)(dong)的執(zhi)行(xing)元(yuan)件，有單葉片(pian)(pian)(pian)、雙葉片(pian)(pian)(pian)、螺旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)等(deng)幾種形(xing)式(shi)(shi)。葉片(pian)(pian)(pian)式(shi)(shi)式(shi)(shi)：定(ding)子塊固定(ding)在(zai)缸(gang)體上，而葉片(pian)(pian)(pian)和轉(zhuan)(zhuan)子連接在(zai)一起。根據進(jin)油(you)方向，葉片(pian)(pian)(pian)將帶動(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)子作往復擺(bai)動(dong)(dong)(dong)(dong)。螺旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)式(shi)(shi)又分單螺旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)和雙螺旋(xuan)兩種，現(xian)在(zai)雙螺旋(xuan)比(bi)較常用，靠兩個(ge)螺旋(xuan)副降液(ye)壓缸(gang)內活(huo)塞的直(zhi)線運(yun)動(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)變為直(zhi)線運(yun)動(dong)(dong)(dong)(dong)與自轉(zhuan)(zhuan)運(yun)動(dong)(dong)(dong)(dong)的復he運(yun)動(dong)(dong)(dong)(dong)，從而實(shi)現(xian)擺(bai)動(dong)(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)(dong)。
緩沖裝置
在(zai)(zai)液(ye)壓(ya)系統中使用(yong)液(ye)壓(ya)缸(gang)驅(qu)動具有(you)一定質量(liang)的機構(gou)，當液(ye)壓(ya)缸(gang)運動至行程(cheng)終(zhong)點時具有(you)較大動能，如未作減速處理(li)，液(ye)壓(ya)缸(gang)活塞與缸(gang)蓋將(jiang)發生機械碰撞，產生沖(chong)擊(ji)、噪聲，有(you)破壞性(xing)。為緩和及防止這種(zhong)危害發生，因此可在(zai)(zai)液(ye)壓(ya)回路(lu)中設(she)置減速裝置或在(zai)(zai)缸(gang)體內設(she)緩沖(chong)裝置。
加工
缸筒(tong)作(zuo)為液壓缸、礦用單(dan)體支柱、液壓支架(jia)、炮管等產品(pin)的(de)主要(yao)部件，其加(jia)工(gong)(gong)(gong)質量的(de)好壞直接影響整(zheng)個產品(pin)的(de)壽命和可(ke)靠(kao)性。缸筒(tong)加(jia)工(gong)(gong)(gong)要(yao)求高，其內表面粗糙(cao)度要(yao)求為Ra0.4～0.8&um，對同軸度、耐磨性要(yao)求嚴格。缸筒(tong)的(de)基(ji)本(ben)特征是(shi)深(shen)孔(kong)加(jia)工(gong)(gong)(gong)，其加(jia)工(gong)(gong)(gong)一(yi)直困(kun)擾加(jia)工(gong)(gong)(gong)人(ren)員。
例如：活(huo)(huo)塞與(yu)活(huo)(huo)塞桿(gan)(gan)(gan)不(bu)同心或活(huo)(huo)塞桿(gan)(gan)(gan)彎曲，液壓缸(gang)或活(huo)(huo)塞桿(gan)(gan)(gan)對導軌安裝位置偏移，密封環裝得過緊或過松等。解決方法(fa)是(shi)重新修理(li)或調整(zheng)，更換損傷的零件及清除鐵屑。
(2)潤滑不(bu)良或液(ye)壓(ya)缸(gang)孔(kong)徑加(jia)工超(chao)差。因為活塞與缸(gang)筒(tong)(tong)、導軌與活塞桿等均有相對運動，如果潤滑不(bu)良或液(ye)壓(ya)缸(gang)孔(kong)徑超(chao)差，就會加(jia)劇磨損(sun)，使(shi)缸(gang)筒(tong)(tong)中心線直(zhi)線性降低。（威海力建冶金液(ye)壓(ya)設備(bei)廠)
