擺動式液壓缸
擺(bai)動(dong)(dong)(dong)(dong)(dong)式(shi)液(ye)(ye)壓缸(gang)是輸出扭(niu)矩并實現往(wang)(wang)復(fu)(fu)(fu)運動(dong)(dong)(dong)(dong)(dong)的執行元件，有單葉片(pian)(pian)(pian)、雙(shuang)葉片(pian)(pian)(pian)、螺(luo)(luo)(luo)旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)等幾種(zhong)形式(shi)。葉片(pian)(pian)(pian)式(shi)式(shi)：定子塊固定在(zai)缸(gang)體(ti)上，而葉片(pian)(pian)(pian)和轉(zhuan)子連接在(zai)一起。根據進油方向(xiang)，葉片(pian)(pian)(pian)將(jiang)帶動(dong)(dong)(dong)(dong)(dong)轉(zhuan)子作往(wang)(wang)復(fu)(fu)(fu)擺(bai)動(dong)(dong)(dong)(dong)(dong)。螺(luo)(luo)(luo)旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)式(shi)又分(fen)單螺(luo)(luo)(luo)旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)和雙(shuang)螺(luo)(luo)(luo)旋(xuan)兩(liang)種(zhong)，現在(zai)雙(shuang)螺(luo)(luo)(luo)旋(xuan)比較常用，靠兩(liang)個螺(luo)(luo)(luo)旋(xuan)副降液(ye)(ye)壓缸(gang)內活(huo)塞(sai)的直線(xian)運動(dong)(dong)(dong)(dong)(dong)轉(zhuan)變為直線(xian)運動(dong)(dong)(dong)(dong)(dong)與(yu)自轉(zhuan)運動(dong)(dong)(dong)(dong)(dong)的復(fu)(fu)(fu)he運動(dong)(dong)(dong)(dong)(dong)，從(cong)而實現擺(bai)動(dong)(dong)(dong)(dong)(dong)運動(dong)(dong)(dong)(dong)(dong)。
緩沖裝置
在液(ye)壓(ya)系(xi)統中使用液(ye)壓(ya)缸(gang)(gang)驅動(dong)具有(you)一定(ding)質量的機(ji)構(gou)，當(dang)液(ye)壓(ya)缸(gang)(gang)運動(dong)至(zhi)行程終點時(shi)具有(you)較大(da)動(dong)能，如未作減速處理，液(ye)壓(ya)缸(gang)(gang)活塞與(yu)缸(gang)(gang)蓋將發(fa)生機(ji)械碰撞，產生沖擊、噪聲，有(you)破壞性。為緩(huan)(huan)和及防止這種危害發(fa)生，因此可(ke)在液(ye)壓(ya)回路中設置減速裝置或在缸(gang)(gang)體內設緩(huan)(huan)沖裝置。
加工
缸(gang)筒(tong)作為液壓缸(gang)、礦(kuang)用(yong)單(dan)體支(zhi)柱、液壓支(zhi)架、炮管(guan)等產(chan)品(pin)的主(zhu)要(yao)部件，其加工(gong)(gong)質(zhi)量(liang)的好壞直接影響整個產(chan)品(pin)的壽命和可(ke)靠性。缸(gang)筒(tong)加工(gong)(gong)要(yao)求高，其內(nei)表面粗糙(cao)度(du)要(yao)求為Ra0.4～0.8&um，對(dui)同軸度(du)、耐磨性要(yao)求嚴格。缸(gang)筒(tong)的基本(ben)特征(zheng)是(shi)深孔加工(gong)(gong)，其加工(gong)(gong)一直困(kun)擾(rao)加工(gong)(gong)人員。
例如：活(huo)塞(sai)與活(huo)塞(sai)桿不(bu)同(tong)心或(huo)活(huo)塞(sai)桿彎曲(qu)，液壓缸或(huo)活(huo)塞(sai)桿對導軌安裝(zhuang)位置(zhi)偏移，密(mi)封環裝(zhuang)得(de)過緊或(huo)過松(song)等。解決(jue)方法是重(zhong)新修理(li)或(huo)調整，更換損傷的零件及(ji)清除鐵屑(xie)。
(2)潤(run)(run)滑(hua)不良(liang)或(huo)液(ye)壓(ya)缸(gang)(gang)孔徑加(jia)工(gong)超(chao)差。因為(wei)活塞(sai)與缸(gang)(gang)筒、導軌(gui)與活塞(sai)桿等均有相(xiang)對運動(dong)，如果潤(run)(run)滑(hua)不良(liang)或(huo)液(ye)壓(ya)缸(gang)(gang)孔徑超(chao)差，就會加(jia)劇磨損，使缸(gang)(gang)筒中(zhong)心線(xian)(xian)直線(xian)(xian)性降低。（威海力建冶金液(ye)壓(ya)設備(bei)廠)
