擺動式液壓缸
擺動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)(shi)(shi)液壓(ya)缸是輸出扭矩并實(shi)(shi)現往(wang)(wang)復(fu)(fu)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的執行元件(jian)，有單葉(xie)(xie)片(pian)、雙(shuang)葉(xie)(xie)片(pian)、螺(luo)旋(xuan)(xuan)擺動(dong)(dong)(dong)(dong)(dong)(dong)等幾種形式(shi)(shi)(shi)。葉(xie)(xie)片(pian)式(shi)(shi)(shi)式(shi)(shi)(shi)：定(ding)(ding)子塊固定(ding)(ding)在缸體(ti)上，而葉(xie)(xie)片(pian)和轉子連(lian)接在一起(qi)。根據進油(you)方向，葉(xie)(xie)片(pian)將帶動(dong)(dong)(dong)(dong)(dong)(dong)轉子作往(wang)(wang)復(fu)(fu)擺動(dong)(dong)(dong)(dong)(dong)(dong)。螺(luo)旋(xuan)(xuan)擺動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)(shi)(shi)又(you)分單螺(luo)旋(xuan)(xuan)擺動(dong)(dong)(dong)(dong)(dong)(dong)和雙(shuang)螺(luo)旋(xuan)(xuan)兩種，現在雙(shuang)螺(luo)旋(xuan)(xuan)比(bi)較常用(yong)，靠兩個螺(luo)旋(xuan)(xuan)副降液壓(ya)缸內活(huo)塞(sai)的直(zhi)線運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)轉變為直(zhi)線運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)與自轉運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的復(fu)(fu)he運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)，從而實(shi)(shi)現擺動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)。
液(ye)壓缸(gang)結構基本(ben)上可以分為(wei)缸(gang)筒和缸(gang)蓋(gai)、活塞和活塞桿、密封裝(zhuang)置、緩沖裝(zhuang)置和排氣(qi)裝(zhuang)置五個部分。今天威海力建小編(bian)著重(zhong)帶著大家(jia)了解一下缸(gang)筒和缸(gang)蓋(gai)。
缸筒和缸蓋
一般(ban)來說，缸筒和缸蓋的結(jie)(jie)構(gou)(gou)形(xing)式(shi)和其使(shi)用(yong)(yong)(yong)(yong)的材料有(you)關。工(gong)作壓力p＜10MPa時(shi)(shi)，使(shi)用(yong)(yong)(yong)(yong)鑄(zhu)鐵(tie)；p＜20MPa時(shi)(shi)，使(shi)用(yong)(yong)(yong)(yong)無縫(feng)鋼(gang)管(guan)；p＞20MPa時(shi)(shi)，使(shi)用(yong)(yong)(yong)(yong)鑄(zhu)鋼(gang)或(huo)(huo)鍛鋼(gang)。法蘭連接式(shi)，結(jie)(jie)構(gou)(gou)簡單(dan)，容易加工(gong)，也容易裝拆，但外形(xing)尺(chi)寸(cun)和重(zhong)量(liang)都較(jiao)大，常用(yong)(yong)(yong)(yong)于(yu)鑄(zhu)鐵(tie)制的缸筒上。半環(huan)連接式(shi)，它的缸筒壁部因(yin)開(kai)了(le)環(huan)形(xing)槽而削弱了(le)強度，為(wei)此有(you)時(shi)(shi)要(yao)加厚缸壁，它容易加工(gong)和裝拆，重(zhong)量(liang)較(jiao)輕，常用(yong)(yong)(yong)(yong)于(yu)無縫(feng)鋼(gang)管(guan)或(huo)(huo)鍛鋼(gang)制的缸筒上。螺紋連接式(shi)，它的缸筒端(duan)部結(jie)(jie)構(gou)(gou)復(fu)雜(za)，外徑(jing)加工(gong)時(shi)(shi)要(yao)求保證(zheng)內外徑(jing)同心，裝拆要(yao)使(shi)用(yong)(yong)(yong)(yong)工(gong)具，它的外形(xing)尺(chi)寸(cun)和重(zhong)量(liang)都較(jiao)小，常用(yong)(yong)(yong)(yong)于(yu)無縫(feng)鋼(gang)管(guan)或(huo)(huo)鑄(zhu)鋼(gang)制的缸筒上。拉桿連接式(shi)，結(jie)(jie)構(gou)(gou)的通用(yong)(yong)(yong)(yong)性大，容易加工(gong)和裝拆，但外形(xing)尺(chi)寸(cun)較(jiao)大，且較(jiao)重(zhong)。焊接連接式(shi)，結(jie)(jie)構(gou)(gou)簡單(dan)，尺(chi)寸(cun)小，但缸底處(chu)內徑(jing)不易加工(gong)，且可能(neng)引起(qi)變形(xing)。
、液壓缸低速爬行的現象
液壓缸的活塞桿在油壓的作用下伸出(chu)或(huo)縮回時(shi)，經(jing)常出(chu)現(xian)速(su)度(du)不均勻(yun)現(xian)象(xiang)(xiang)，并有時(shi)伴(ban)有振(zhen)動和(he)異(yi)響，從(cong)而引起(qi)整個液壓系統的振(zhen)動，并帶動主機(ji)其(qi)它部件(jian)振(zhen)動，在主機(ji)調試過程中經(jing)常出(chu)現(xian)，有時(shi)速(su)度(du)快了，這種現(xian)象(xiang)(xiang)會(hui)減輕。除因(yin)液壓系統管路引起(qi)這種現(xian)象(xiang)(xiang)以外，液壓缸自身產生的振(zhen)動也(ye)經(jing)常引發此類現(xian)象(xiang)(xiang)。
原因分析
液壓(ya)(ya)缸(gang)有(you)桿腔和(he)無桿腔存有(you)氣(qi)體而產生的低速爬行，由(you)于氣(qi)體混在液壓(ya)(ya)油中(zhong)，在壓(ya)(ya)力的作用下，容器內(nei)體積變化，在高壓(ya)(ya)作用下甚至(zhi)發生氣(qi)體瞬(shun)間，從而引起液壓(ya)(ya)缸(gang)的速度不穩定。
