擺動式液壓缸
擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)式(shi)(shi)液(ye)壓缸(gang)是輸出(chu)扭矩并(bing)實現往(wang)復運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)執行元件，有(you)單葉(xie)片、雙葉(xie)片、螺旋(xuan)擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)等幾種形式(shi)(shi)。葉(xie)片式(shi)(shi)式(shi)(shi)：定子塊(kuai)固定在(zai)缸(gang)體上，而葉(xie)片和轉子連接(jie)在(zai)一起(qi)。根據進油方向，葉(xie)片將帶動(dong)(dong)(dong)(dong)(dong)轉子作(zuo)往(wang)復擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)。螺旋(xuan)擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)式(shi)(shi)又分單螺旋(xuan)擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)和雙螺旋(xuan)兩種，現在(zai)雙螺旋(xuan)比(bi)較(jiao)常用，靠兩個螺旋(xuan)副降液(ye)壓缸(gang)內活(huo)塞(sai)的(de)直線(xian)運(yun)動(dong)(dong)(dong)(dong)(dong)轉變為(wei)直線(xian)運(yun)動(dong)(dong)(dong)(dong)(dong)與自轉運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)復he運(yun)動(dong)(dong)(dong)(dong)(dong)，從而實現擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)(dong)(dong)。
液壓缸(gang)結構基本上可以分(fen)為(wei)缸(gang)筒和缸(gang)蓋(gai)、活塞(sai)和活塞(sai)桿、密封裝(zhuang)置、緩沖(chong)裝(zhuang)置和排氣裝(zhuang)置五個部分(fen)。今天威海力建小編(bian)著重帶著大家(jia)了解(jie)一下缸(gang)筒和缸(gang)蓋(gai)。
缸筒和缸蓋
一般來說，缸筒(tong)(tong)和(he)缸蓋的(de)(de)(de)(de)結(jie)構(gou)形(xing)(xing)式和(he)其使用(yong)(yong)的(de)(de)(de)(de)材料有(you)關。工(gong)作壓力p＜10MPa時(shi)(shi)，使用(yong)(yong)鑄鐵(tie)；p＜20MPa時(shi)(shi)，使用(yong)(yong)無(wu)(wu)縫鋼(gang)管(guan)；p＞20MPa時(shi)(shi)，使用(yong)(yong)鑄鋼(gang)或(huo)鍛(duan)鋼(gang)。法蘭連(lian)接(jie)式，結(jie)構(gou)簡單(dan)，容(rong)易(yi)加(jia)(jia)工(gong)，也容(rong)易(yi)裝(zhuang)拆(chai)(chai)，但外(wai)(wai)形(xing)(xing)尺(chi)(chi)(chi)寸(cun)和(he)重(zhong)(zhong)量(liang)都(dou)較(jiao)大(da)，常用(yong)(yong)于(yu)(yu)鑄鐵(tie)制的(de)(de)(de)(de)缸筒(tong)(tong)上(shang)。半環連(lian)接(jie)式，它的(de)(de)(de)(de)缸筒(tong)(tong)壁部(bu)因開(kai)了(le)環形(xing)(xing)槽(cao)而削弱了(le)強(qiang)度，為此有(you)時(shi)(shi)要加(jia)(jia)厚缸壁，它容(rong)易(yi)加(jia)(jia)工(gong)和(he)裝(zhuang)拆(chai)(chai)，重(zhong)(zhong)量(liang)較(jiao)輕，常用(yong)(yong)于(yu)(yu)無(wu)(wu)縫鋼(gang)管(guan)或(huo)鍛(duan)鋼(gang)制的(de)(de)(de)(de)缸筒(tong)(tong)上(shang)。螺紋連(lian)接(jie)式，它的(de)(de)(de)(de)缸筒(tong)(tong)端(duan)部(bu)結(jie)構(gou)復雜(za)，外(wai)(wai)徑(jing)加(jia)(jia)工(gong)時(shi)(shi)要求保證內外(wai)(wai)徑(jing)同心，裝(zhuang)拆(chai)(chai)要使用(yong)(yong)工(gong)具，它的(de)(de)(de)(de)外(wai)(wai)形(xing)(xing)尺(chi)(chi)(chi)寸(cun)和(he)重(zhong)(zhong)量(liang)都(dou)較(jiao)小(xiao)，常用(yong)(yong)于(yu)(yu)無(wu)(wu)縫鋼(gang)管(guan)或(huo)鑄鋼(gang)制的(de)(de)(de)(de)缸筒(tong)(tong)上(shang)。拉桿連(lian)接(jie)式，結(jie)構(gou)的(de)(de)(de)(de)通用(yong)(yong)性大(da)，容(rong)易(yi)加(jia)(jia)工(gong)和(he)裝(zhuang)拆(chai)(chai)，但外(wai)(wai)形(xing)(xing)尺(chi)(chi)(chi)寸(cun)較(jiao)大(da)，且(qie)較(jiao)重(zhong)(zhong)。焊接(jie)連(lian)接(jie)式，結(jie)構(gou)簡單(dan)，尺(chi)(chi)(chi)寸(cun)小(xiao)，但缸底處內徑(jing)不易(yi)加(jia)(jia)工(gong)，且(qie)可能引(yin)起變形(xing)(xing)。
、液壓(ya)缸(gang)低(di)速爬行的現象(xiang)
液壓缸的(de)活塞桿在油壓的(de)作(zuo)用下伸出(chu)或(huo)縮(suo)回時，經常(chang)出(chu)現(xian)速(su)度不(bu)均勻現(xian)象(xiang)(xiang)，并有(you)時伴(ban)有(you)振(zhen)(zhen)動(dong)和異響，從而引(yin)(yin)起整個液壓系統(tong)的(de)振(zhen)(zhen)動(dong)，并帶動(dong)主(zhu)機其它部(bu)件(jian)振(zhen)(zhen)動(dong)，在主(zhu)機調試過程(cheng)中經常(chang)出(chu)現(xian)，有(you)時速(su)度快了，這(zhe)種(zhong)(zhong)現(xian)象(xiang)(xiang)會減(jian)輕。除因液壓系統(tong)管路引(yin)(yin)起這(zhe)種(zhong)(zhong)現(xian)象(xiang)(xiang)以(yi)外，液壓缸自身產生的(de)振(zhen)(zhen)動(dong)也(ye)經常(chang)引(yin)(yin)發此類現(xian)象(xiang)(xiang)。
原因分析
液壓(ya)缸(gang)有(you)桿腔(qiang)和無桿腔(qiang)存有(you)氣體而(er)產生(sheng)的(de)低(di)速爬(pa)行，由于氣體混在液壓(ya)油中，在壓(ya)力的(de)作(zuo)用下(xia)，容器(qi)內體積變化，在高壓(ya)作(zuo)用下(xia)甚(shen)至發生(sheng)氣體瞬間，從而(er)引起液壓(ya)缸(gang)的(de)速度(du)不穩定。
