擺動式液壓缸
擺(bai)(bai)(bai)動(dong)(dong)(dong)式液壓(ya)(ya)缸是輸出扭矩并(bing)實(shi)現(xian)往復運(yun)動(dong)(dong)(dong)的執行(xing)元(yuan)件，有單(dan)葉(xie)片(pian)、雙葉(xie)片(pian)、螺(luo)(luo)(luo)旋(xuan)(xuan)擺(bai)(bai)(bai)動(dong)(dong)(dong)等幾種(zhong)形(xing)式。葉(xie)片(pian)式式：定(ding)子塊固(gu)定(ding)在(zai)缸體上，而葉(xie)片(pian)和轉(zhuan)(zhuan)子連接在(zai)一起(qi)。根據進(jin)油方向，葉(xie)片(pian)將帶動(dong)(dong)(dong)轉(zhuan)(zhuan)子作往復擺(bai)(bai)(bai)動(dong)(dong)(dong)。螺(luo)(luo)(luo)旋(xuan)(xuan)擺(bai)(bai)(bai)動(dong)(dong)(dong)式又分(fen)單(dan)螺(luo)(luo)(luo)旋(xuan)(xuan)擺(bai)(bai)(bai)動(dong)(dong)(dong)和雙螺(luo)(luo)(luo)旋(xuan)(xuan)兩種(zhong)，現(xian)在(zai)雙螺(luo)(luo)(luo)旋(xuan)(xuan)比較常用，靠兩個螺(luo)(luo)(luo)旋(xuan)(xuan)副降(jiang)液壓(ya)(ya)缸內活(huo)塞的直線運(yun)動(dong)(dong)(dong)轉(zhuan)(zhuan)變為直線運(yun)動(dong)(dong)(dong)與自轉(zhuan)(zhuan)運(yun)動(dong)(dong)(dong)的復he運(yun)動(dong)(dong)(dong)，從(cong)而實(shi)現(xian)擺(bai)(bai)(bai)動(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)。
液壓(ya)缸結(jie)構(gou)基本(ben)上(shang)可以分(fen)為缸筒(tong)和(he)缸蓋、活塞(sai)和(he)活塞(sai)桿、密封裝置、緩沖裝置和(he)排氣裝置五(wu)個部(bu)分(fen)。今天(tian)威海力建小(xiao)編著重帶著大家了解一下缸筒(tong)和(he)缸蓋。
缸筒和缸蓋(gai)
一般來(lai)說，缸(gang)(gang)筒(tong)和(he)缸(gang)(gang)蓋的(de)結構(gou)(gou)形式(shi)和(he)其使(shi)用(yong)的(de)材料有關。工(gong)(gong)作(zuo)壓(ya)力p＜10MPa時，使(shi)用(yong)鑄鐵；p＜20MPa時，使(shi)用(yong)無縫(feng)鋼(gang)管；p＞20MPa時，使(shi)用(yong)鑄鋼(gang)或(huo)鍛(duan)鋼(gang)。法(fa)蘭連(lian)接(jie)式(shi)，結構(gou)(gou)簡單，容(rong)易(yi)(yi)加(jia)(jia)工(gong)(gong)，也容(rong)易(yi)(yi)裝(zhuang)拆(chai)，但(dan)外(wai)形尺(chi)(chi)寸和(he)重(zhong)量都較(jiao)(jiao)大，常(chang)用(yong)于鑄鐵制(zhi)的(de)缸(gang)(gang)筒(tong)上(shang)。半環連(lian)接(jie)式(shi)，它的(de)缸(gang)(gang)筒(tong)壁部(bu)因開了(le)環形槽(cao)而削(xue)弱(ruo)了(le)強度，為此有時要加(jia)(jia)厚缸(gang)(gang)壁，它容(rong)易(yi)(yi)加(jia)(jia)工(gong)(gong)和(he)裝(zhuang)拆(chai)，重(zhong)量較(jiao)(jiao)輕，常(chang)用(yong)于無縫(feng)鋼(gang)管或(huo)鍛(duan)鋼(gang)制(zhi)的(de)缸(gang)(gang)筒(tong)上(shang)。螺紋連(lian)接(jie)式(shi)，它的(de)缸(gang)(gang)筒(tong)端部(bu)結構(gou)(gou)復雜，外(wai)徑(jing)加(jia)(jia)工(gong)(gong)時要求保證內外(wai)徑(jing)同心(xin)，裝(zhuang)拆(chai)要使(shi)用(yong)工(gong)(gong)具，它的(de)外(wai)形尺(chi)(chi)寸和(he)重(zhong)量都較(jiao)(jiao)小，常(chang)用(yong)于無縫(feng)鋼(gang)管或(huo)鑄鋼(gang)制(zhi)的(de)缸(gang)(gang)筒(tong)上(shang)。拉桿(gan)連(lian)接(jie)式(shi)，結構(gou)(gou)的(de)通用(yong)性(xing)大，容(rong)易(yi)(yi)加(jia)(jia)工(gong)(gong)和(he)裝(zhuang)拆(chai)，但(dan)外(wai)形尺(chi)(chi)寸較(jiao)(jiao)大，且較(jiao)(jiao)重(zhong)。焊接(jie)連(lian)接(jie)式(shi)，結構(gou)(gou)簡單，尺(chi)(chi)寸小，但(dan)缸(gang)(gang)底處內徑(jing)不易(yi)(yi)加(jia)(jia)工(gong)(gong)，且可(ke)能引起變形。
、液(ye)壓缸(gang)低(di)速爬行的(de)現象
液壓(ya)缸(gang)的活(huo)塞桿(gan)在油壓(ya)的作用下伸出或縮(suo)回(hui)時(shi)，經常(chang)出現(xian)(xian)速(su)度(du)不(bu)均勻現(xian)(xian)象，并有(you)時(shi)伴有(you)振動(dong)(dong)和異(yi)響，從而引起整個液壓(ya)系(xi)統的振動(dong)(dong)，并帶動(dong)(dong)主機其(qi)它部件(jian)振動(dong)(dong)，在主機調試(shi)過程(cheng)中經常(chang)出現(xian)(xian)，有(you)時(shi)速(su)度(du)快(kuai)了，這種(zhong)現(xian)(xian)象會減輕。除因液壓(ya)系(xi)統管(guan)路引起這種(zhong)現(xian)(xian)象以外，液壓(ya)缸(gang)自(zi)身產生的振動(dong)(dong)也經常(chang)引發此類現(xian)(xian)象。
原因分析
液壓(ya)缸有(you)桿腔和無桿腔存(cun)有(you)氣(qi)(qi)體(ti)(ti)而產生(sheng)的低速爬(pa)行，由(you)于氣(qi)(qi)體(ti)(ti)混(hun)在液壓(ya)油中，在壓(ya)力的作用下，容器內體(ti)(ti)積(ji)變化(hua)，在高壓(ya)作用下甚(shen)至(zhi)發生(sheng)氣(qi)(qi)體(ti)(ti)瞬間(jian)，從而引起液壓(ya)缸的速度不穩定。
