擺動式液壓缸
擺(bai)動(dong)(dong)(dong)(dong)式(shi)(shi)液壓缸(gang)是輸出扭矩并實現(xian)(xian)往復運動(dong)(dong)(dong)(dong)的執行元(yuan)件，有單(dan)葉(xie)(xie)(xie)片(pian)(pian)、雙葉(xie)(xie)(xie)片(pian)(pian)、螺旋擺(bai)動(dong)(dong)(dong)(dong)等幾種形式(shi)(shi)。葉(xie)(xie)(xie)片(pian)(pian)式(shi)(shi)式(shi)(shi)：定子(zi)塊(kuai)固(gu)定在缸(gang)體上，而(er)葉(xie)(xie)(xie)片(pian)(pian)和(he)轉(zhuan)子(zi)連(lian)接(jie)在一(yi)起。根據進油(you)方向(xiang)，葉(xie)(xie)(xie)片(pian)(pian)將帶動(dong)(dong)(dong)(dong)轉(zhuan)子(zi)作(zuo)往復擺(bai)動(dong)(dong)(dong)(dong)。螺旋擺(bai)動(dong)(dong)(dong)(dong)式(shi)(shi)又分單(dan)螺旋擺(bai)動(dong)(dong)(dong)(dong)和(he)雙螺旋兩種，現(xian)(xian)在雙螺旋比較常用，靠兩個螺旋副(fu)降液壓缸(gang)內活塞(sai)的直線運動(dong)(dong)(dong)(dong)轉(zhuan)變為直線運動(dong)(dong)(dong)(dong)與自轉(zhuan)運動(dong)(dong)(dong)(dong)的復he運動(dong)(dong)(dong)(dong)，從而(er)實現(xian)(xian)擺(bai)動(dong)(dong)(dong)(dong)運動(dong)(dong)(dong)(dong)。
液壓缸(gang)(gang)結(jie)構基本上可以分(fen)(fen)為(wei)缸(gang)(gang)筒和缸(gang)(gang)蓋(gai)、活(huo)塞(sai)和活(huo)塞(sai)桿、密封(feng)裝(zhuang)置(zhi)、緩沖(chong)裝(zhuang)置(zhi)和排氣裝(zhuang)置(zhi)五個部分(fen)(fen)。今天威海力建小編著重帶著大家了解一下缸(gang)(gang)筒和缸(gang)(gang)蓋(gai)。
缸(gang)筒和缸(gang)蓋
一(yi)般來說，缸(gang)(gang)筒(tong)和缸(gang)(gang)蓋的(de)結構(gou)形(xing)式(shi)和其使(shi)用(yong)(yong)的(de)材料有(you)關。工(gong)(gong)作壓(ya)力p＜10MPa時(shi)(shi)，使(shi)用(yong)(yong)鑄鐵(tie)；p＜20MPa時(shi)(shi)，使(shi)用(yong)(yong)無(wu)縫(feng)鋼(gang)管；p＞20MPa時(shi)(shi)，使(shi)用(yong)(yong)鑄鋼(gang)或(huo)(huo)鍛(duan)鋼(gang)。法蘭連(lian)(lian)接(jie)式(shi)，結構(gou)簡單，容(rong)易(yi)加(jia)工(gong)(gong)，也容(rong)易(yi)裝拆(chai)，但外(wai)形(xing)尺(chi)(chi)(chi)寸和重(zhong)量都較(jiao)(jiao)(jiao)大，常(chang)用(yong)(yong)于鑄鐵(tie)制的(de)缸(gang)(gang)筒(tong)上。半環(huan)連(lian)(lian)接(jie)式(shi)，它的(de)缸(gang)(gang)筒(tong)壁(bi)部因開了(le)環(huan)形(xing)槽(cao)而(er)削弱了(le)強(qiang)度，為此有(you)時(shi)(shi)要加(jia)厚缸(gang)(gang)壁(bi)，它容(rong)易(yi)加(jia)工(gong)(gong)和裝拆(chai)，重(zhong)量較(jiao)(jiao)(jiao)輕(qing)，常(chang)用(yong)(yong)于無(wu)縫(feng)鋼(gang)管或(huo)(huo)鍛(duan)鋼(gang)制的(de)缸(gang)(gang)筒(tong)上。螺紋連(lian)(lian)接(jie)式(shi)，它的(de)缸(gang)(gang)筒(tong)端部結構(gou)復雜，外(wai)徑(jing)加(jia)工(gong)(gong)時(shi)(shi)要求保證(zheng)內外(wai)徑(jing)同(tong)心，裝拆(chai)要使(shi)用(yong)(yong)工(gong)(gong)具，它的(de)外(wai)形(xing)尺(chi)(chi)(chi)寸和重(zhong)量都較(jiao)(jiao)(jiao)小(xiao)，常(chang)用(yong)(yong)于無(wu)縫(feng)鋼(gang)管或(huo)(huo)鑄鋼(gang)制的(de)缸(gang)(gang)筒(tong)上。拉桿連(lian)(lian)接(jie)式(shi)，結構(gou)的(de)通用(yong)(yong)性大，容(rong)易(yi)加(jia)工(gong)(gong)和裝拆(chai)，但外(wai)形(xing)尺(chi)(chi)(chi)寸較(jiao)(jiao)(jiao)大，且較(jiao)(jiao)(jiao)重(zhong)。焊接(jie)連(lian)(lian)接(jie)式(shi)，結構(gou)簡單，尺(chi)(chi)(chi)寸小(xiao)，但缸(gang)(gang)底(di)處內徑(jing)不易(yi)加(jia)工(gong)(gong)，且可能引起變形(xing)。
、液壓缸(gang)低(di)速爬行(xing)的(de)現象
液(ye)壓(ya)缸(gang)(gang)的(de)活塞桿在油壓(ya)的(de)作用下伸出或縮回時，經(jing)常出現(xian)速度不均勻現(xian)象，并有(you)時伴有(you)振(zhen)動(dong)和異響，從而引起整個液(ye)壓(ya)系(xi)統(tong)(tong)的(de)振(zhen)動(dong)，并帶動(dong)主機其它部件振(zhen)動(dong)，在主機調試過程中經(jing)常出現(xian)，有(you)時速度快了，這(zhe)種現(xian)象會減輕(qing)。除因液(ye)壓(ya)系(xi)統(tong)(tong)管(guan)路(lu)引起這(zhe)種現(xian)象以外，液(ye)壓(ya)缸(gang)(gang)自身(shen)產生的(de)振(zhen)動(dong)也(ye)經(jing)常引發此類(lei)現(xian)象。
原因分析
液壓缸(gang)有(you)桿腔(qiang)和(he)無桿腔(qiang)存有(you)氣體而產生(sheng)的低速爬行，由于氣體混在液壓油中，在壓力的作用(yong)下，容(rong)器內(nei)體積(ji)變化，在高(gao)壓作用(yong)下甚至發生(sheng)氣體瞬間，從而引(yin)起液壓缸(gang)的速度(du)不穩定。
