擺動式液壓缸
擺(bai)動(dong)(dong)(dong)(dong)式液壓缸(gang)是輸出(chu)扭(niu)矩并實(shi)現往(wang)(wang)復(fu)運動(dong)(dong)(dong)(dong)的執行元件，有單葉片(pian)(pian)、雙葉片(pian)(pian)、螺(luo)旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)等(deng)幾種(zhong)形式。葉片(pian)(pian)式式：定子塊固定在(zai)缸(gang)體上，而(er)葉片(pian)(pian)和轉(zhuan)(zhuan)子連(lian)接(jie)在(zai)一(yi)起。根據進油方向，葉片(pian)(pian)將帶動(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)子作(zuo)往(wang)(wang)復(fu)擺(bai)動(dong)(dong)(dong)(dong)。螺(luo)旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)式又(you)分單螺(luo)旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)和雙螺(luo)旋(xuan)兩種(zhong)，現在(zai)雙螺(luo)旋(xuan)比(bi)較常用，靠兩個螺(luo)旋(xuan)副降液壓缸(gang)內活塞的直(zhi)線(xian)運動(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)變為直(zhi)線(xian)運動(dong)(dong)(dong)(dong)與自轉(zhuan)(zhuan)運動(dong)(dong)(dong)(dong)的復(fu)he運動(dong)(dong)(dong)(dong)，從而(er)實(shi)現擺(bai)動(dong)(dong)(dong)(dong)運動(dong)(dong)(dong)(dong)。
液壓缸(gang)結構基本上可以分(fen)為缸(gang)筒和缸(gang)蓋、活(huo)塞(sai)和活(huo)塞(sai)桿、密(mi)封裝(zhuang)置、緩沖裝(zhuang)置和排氣(qi)裝(zhuang)置五(wu)個部分(fen)。今天威海力建(jian)小編著重帶著大家了解(jie)一下缸(gang)筒和缸(gang)蓋。
缸筒(tong)和缸蓋
一(yi)般來說，缸(gang)(gang)筒(tong)(tong)和缸(gang)(gang)蓋的(de)(de)(de)結(jie)(jie)構(gou)形(xing)式和其使(shi)用(yong)的(de)(de)(de)材料有關。工(gong)(gong)作壓力p＜10MPa時，使(shi)用(yong)鑄(zhu)(zhu)鐵；p＜20MPa時，使(shi)用(yong)無(wu)縫鋼(gang)管(guan)(guan)；p＞20MPa時，使(shi)用(yong)鑄(zhu)(zhu)鋼(gang)或(huo)鍛鋼(gang)。法(fa)蘭連接(jie)式，結(jie)(jie)構(gou)簡單，容易加(jia)工(gong)(gong)，也容易裝拆(chai)(chai)，但外(wai)形(xing)尺(chi)(chi)寸(cun)和重(zhong)(zhong)(zhong)量(liang)都(dou)較大(da)，常(chang)用(yong)于(yu)鑄(zhu)(zhu)鐵制(zhi)的(de)(de)(de)缸(gang)(gang)筒(tong)(tong)上。半環(huan)(huan)連接(jie)式，它(ta)的(de)(de)(de)缸(gang)(gang)筒(tong)(tong)壁(bi)部因開(kai)了環(huan)(huan)形(xing)槽而削弱了強度，為此有時要加(jia)厚缸(gang)(gang)壁(bi)，它(ta)容易加(jia)工(gong)(gong)和裝拆(chai)(chai)，重(zhong)(zhong)(zhong)量(liang)較輕，常(chang)用(yong)于(yu)無(wu)縫鋼(gang)管(guan)(guan)或(huo)鍛鋼(gang)制(zhi)的(de)(de)(de)缸(gang)(gang)筒(tong)(tong)上。螺(luo)紋連接(jie)式，它(ta)的(de)(de)(de)缸(gang)(gang)筒(tong)(tong)端(duan)部結(jie)(jie)構(gou)復雜，外(wai)徑(jing)加(jia)工(gong)(gong)時要求保證內外(wai)徑(jing)同心(xin)，裝拆(chai)(chai)要使(shi)用(yong)工(gong)(gong)具，它(ta)的(de)(de)(de)外(wai)形(xing)尺(chi)(chi)寸(cun)和重(zhong)(zhong)(zhong)量(liang)都(dou)較小，常(chang)用(yong)于(yu)無(wu)縫鋼(gang)管(guan)(guan)或(huo)鑄(zhu)(zhu)鋼(gang)制(zhi)的(de)(de)(de)缸(gang)(gang)筒(tong)(tong)上。拉(la)桿(gan)連接(jie)式，結(jie)(jie)構(gou)的(de)(de)(de)通用(yong)性大(da)，容易加(jia)工(gong)(gong)和裝拆(chai)(chai)，但外(wai)形(xing)尺(chi)(chi)寸(cun)較大(da)，且(qie)較重(zhong)(zhong)(zhong)。焊(han)接(jie)連接(jie)式，結(jie)(jie)構(gou)簡單，尺(chi)(chi)寸(cun)小，但缸(gang)(gang)底處內徑(jing)不易加(jia)工(gong)(gong)，且(qie)可能(neng)引(yin)起變形(xing)。
、液壓缸低(di)速爬行的現象
液壓(ya)(ya)(ya)缸(gang)的(de)活塞桿在(zai)油壓(ya)(ya)(ya)的(de)作(zuo)用下伸出或縮回時(shi)，經(jing)常出現速度不均勻(yun)現象(xiang)(xiang)，并有時(shi)伴有振(zhen)動(dong)和異響，從而引起(qi)整(zheng)個液壓(ya)(ya)(ya)系統的(de)振(zhen)動(dong)，并帶動(dong)主機其它部件振(zhen)動(dong)，在(zai)主機調試過程(cheng)中經(jing)常出現，有時(shi)速度快了，這種現象(xiang)(xiang)會減輕(qing)。除因液壓(ya)(ya)(ya)系統管路引起(qi)這種現象(xiang)(xiang)以外，液壓(ya)(ya)(ya)缸(gang)自(zi)身產生的(de)振(zhen)動(dong)也經(jing)常引發此類現象(xiang)(xiang)。
原因分析
液壓缸(gang)有(you)桿腔和無桿腔存有(you)氣體而(er)產生的(de)低(di)速爬行，由于氣體混在液壓油中，在壓力的(de)作(zuo)用下，容器內(nei)體積(ji)變化，在高(gao)壓作(zuo)用下甚(shen)至發生氣體瞬間，從(cong)而(er)引(yin)起(qi)液壓缸(gang)的(de)速度不穩定。
