擺動式液壓缸
擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)液壓(ya)缸是輸(shu)出扭矩并實現(xian)往復(fu)運動(dong)(dong)(dong)(dong)(dong)(dong)的執行元(yuan)件，有單(dan)葉(xie)片(pian)、雙葉(xie)片(pian)、螺(luo)(luo)(luo)旋擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)等幾種(zhong)(zhong)形式(shi)。葉(xie)片(pian)式(shi)式(shi)：定子塊固(gu)定在缸體上，而(er)葉(xie)片(pian)和轉(zhuan)(zhuan)(zhuan)子連(lian)接(jie)在一起。根據進油方向，葉(xie)片(pian)將(jiang)帶動(dong)(dong)(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)(zhuan)子作(zuo)往復(fu)擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)。螺(luo)(luo)(luo)旋擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)又分單(dan)螺(luo)(luo)(luo)旋擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)和雙螺(luo)(luo)(luo)旋兩種(zhong)(zhong)，現(xian)在雙螺(luo)(luo)(luo)旋比較常用，靠兩個螺(luo)(luo)(luo)旋副降液壓(ya)缸內活塞的直線運動(dong)(dong)(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)(zhuan)變(bian)為直線運動(dong)(dong)(dong)(dong)(dong)(dong)與自轉(zhuan)(zhuan)(zhuan)運動(dong)(dong)(dong)(dong)(dong)(dong)的復(fu)he運動(dong)(dong)(dong)(dong)(dong)(dong)，從而(er)實現(xian)擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)運動(dong)(dong)(dong)(dong)(dong)(dong)。
緩沖裝置
在液(ye)壓系統(tong)中(zhong)使用液(ye)壓缸(gang)(gang)驅動(dong)具有一定(ding)質量(liang)的機構，當液(ye)壓缸(gang)(gang)運動(dong)至行程終點時具有較大動(dong)能，如未作減速處理，液(ye)壓缸(gang)(gang)活塞與缸(gang)(gang)蓋將發生機械碰撞，產生沖擊、噪(zao)聲，有破壞(huai)性。為緩(huan)和及防止這種(zhong)危(wei)害發生，因此可在液(ye)壓回路中(zhong)設(she)置減速裝(zhuang)置或在缸(gang)(gang)體內設(she)緩(huan)沖裝(zhuang)置。
加工
缸筒(tong)作為液(ye)壓缸、礦用單體支(zhi)柱、液(ye)壓支(zhi)架、炮管等產(chan)品(pin)的(de)(de)主要部(bu)件，其(qi)加(jia)工質量的(de)(de)好壞(huai)直接影(ying)響整個產(chan)品(pin)的(de)(de)壽命和可(ke)靠性。缸筒(tong)加(jia)工要求高，其(qi)內表面粗糙(cao)度(du)要求為Ra0.4～0.8&um，對(dui)同軸度(du)、耐磨性要求嚴格。缸筒(tong)的(de)(de)基本(ben)特征是深孔加(jia)工，其(qi)加(jia)工一直困(kun)擾加(jia)工人員。
例如(ru)：活塞(sai)與活塞(sai)桿不(bu)同心或活塞(sai)桿彎曲，液(ye)壓缸或活塞(sai)桿對導(dao)軌安裝(zhuang)位置偏(pian)移，密封環裝(zhuang)得過緊或過松等。解決方法是重新修(xiu)理或調整，更換損傷的零(ling)件(jian)及清除鐵屑。
(2)潤滑不(bu)良或(huo)液壓(ya)缸孔徑加(jia)工超(chao)差。因為(wei)活塞與缸筒(tong)(tong)、導軌(gui)與活塞桿等均有相對運動，如果潤滑不(bu)良或(huo)液壓(ya)缸孔徑超(chao)差，就會(hui)加(jia)劇(ju)磨(mo)損(sun)，使缸筒(tong)(tong)中(zhong)心線(xian)直線(xian)性降低。（威海力建冶金(jin)液壓(ya)設備廠)
