擺動式液壓缸
擺動(dong)(dong)(dong)(dong)式(shi)(shi)液壓(ya)缸(gang)是輸(shu)出扭矩(ju)并實現(xian)往復運(yun)動(dong)(dong)(dong)(dong)的(de)(de)(de)執行元件，有單(dan)葉(xie)片(pian)(pian)(pian)、雙(shuang)葉(xie)片(pian)(pian)(pian)、螺(luo)(luo)旋擺動(dong)(dong)(dong)(dong)等幾種形式(shi)(shi)。葉(xie)片(pian)(pian)(pian)式(shi)(shi)式(shi)(shi)：定(ding)子塊(kuai)固定(ding)在(zai)缸(gang)體上，而葉(xie)片(pian)(pian)(pian)和(he)轉(zhuan)子連(lian)接在(zai)一(yi)起。根據(ju)進油(you)方向，葉(xie)片(pian)(pian)(pian)將帶動(dong)(dong)(dong)(dong)轉(zhuan)子作往復擺動(dong)(dong)(dong)(dong)。螺(luo)(luo)旋擺動(dong)(dong)(dong)(dong)式(shi)(shi)又分單(dan)螺(luo)(luo)旋擺動(dong)(dong)(dong)(dong)和(he)雙(shuang)螺(luo)(luo)旋兩種，現(xian)在(zai)雙(shuang)螺(luo)(luo)旋比(bi)較(jiao)常(chang)用，靠兩個螺(luo)(luo)旋副降液壓(ya)缸(gang)內活塞的(de)(de)(de)直(zhi)線運(yun)動(dong)(dong)(dong)(dong)轉(zhuan)變為直(zhi)線運(yun)動(dong)(dong)(dong)(dong)與自轉(zhuan)運(yun)動(dong)(dong)(dong)(dong)的(de)(de)(de)復he運(yun)動(dong)(dong)(dong)(dong)，從而實現(xian)擺動(dong)(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)(dong)。
液壓缸(gang)結(jie)構(gou)基本上可以分為(wei)缸(gang)筒(tong)和缸(gang)蓋、活(huo)塞和活(huo)塞桿(gan)、密封裝(zhuang)置(zhi)、緩沖裝(zhuang)置(zhi)和排氣裝(zhuang)置(zhi)五個部分。今天威海力建小編著重帶著大家了(le)解一下(xia)缸(gang)筒(tong)和缸(gang)蓋。
缸筒和缸蓋
一般來說，缸(gang)筒(tong)(tong)和(he)缸(gang)蓋的(de)(de)(de)結(jie)構(gou)(gou)形(xing)式(shi)(shi)(shi)和(he)其(qi)使用(yong)(yong)的(de)(de)(de)材料有關。工(gong)(gong)作壓力(li)p＜10MPa時，使用(yong)(yong)鑄鐵(tie)(tie)；p＜20MPa時，使用(yong)(yong)無縫(feng)(feng)鋼(gang)管；p＞20MPa時，使用(yong)(yong)鑄鋼(gang)或鍛(duan)鋼(gang)。法蘭連接(jie)式(shi)(shi)(shi)，結(jie)構(gou)(gou)簡單(dan)，容(rong)易(yi)加(jia)(jia)工(gong)(gong)，也(ye)容(rong)易(yi)裝拆，但外(wai)(wai)(wai)形(xing)尺寸(cun)和(he)重(zhong)量(liang)都較(jiao)(jiao)大，常用(yong)(yong)于鑄鐵(tie)(tie)制的(de)(de)(de)缸(gang)筒(tong)(tong)上。半(ban)環連接(jie)式(shi)(shi)(shi)，它的(de)(de)(de)缸(gang)筒(tong)(tong)壁部(bu)因開了環形(xing)槽(cao)而削弱了強度，為此(ci)有時要(yao)加(jia)(jia)厚缸(gang)壁，它容(rong)易(yi)加(jia)(jia)工(gong)(gong)和(he)裝拆，重(zhong)量(liang)較(jiao)(jiao)輕(qing)，常用(yong)(yong)于無縫(feng)(feng)鋼(gang)管或鍛(duan)鋼(gang)制的(de)(de)(de)缸(gang)筒(tong)(tong)上。螺紋連接(jie)式(shi)(shi)(shi)，它的(de)(de)(de)缸(gang)筒(tong)(tong)端(duan)部(bu)結(jie)構(gou)(gou)復(fu)雜，外(wai)(wai)(wai)徑(jing)加(jia)(jia)工(gong)(gong)時要(yao)求保證內(nei)外(wai)(wai)(wai)徑(jing)同心，裝拆要(yao)使用(yong)(yong)工(gong)(gong)具，它的(de)(de)(de)外(wai)(wai)(wai)形(xing)尺寸(cun)和(he)重(zhong)量(liang)都較(jiao)(jiao)小，常用(yong)(yong)于無縫(feng)(feng)鋼(gang)管或鑄鋼(gang)制的(de)(de)(de)缸(gang)筒(tong)(tong)上。拉(la)桿連接(jie)式(shi)(shi)(shi)，結(jie)構(gou)(gou)的(de)(de)(de)通用(yong)(yong)性大，容(rong)易(yi)加(jia)(jia)工(gong)(gong)和(he)裝拆，但外(wai)(wai)(wai)形(xing)尺寸(cun)較(jiao)(jiao)大，且較(jiao)(jiao)重(zhong)。焊接(jie)連接(jie)式(shi)(shi)(shi)，結(jie)構(gou)(gou)簡單(dan)，尺寸(cun)小，但缸(gang)底處內(nei)徑(jing)不易(yi)加(jia)(jia)工(gong)(gong)，且可能引起變形(xing)。
、液壓缸低(di)速爬行(xing)的現象(xiang)
液(ye)壓(ya)缸(gang)(gang)的(de)活塞桿在(zai)油壓(ya)的(de)作(zuo)用下(xia)伸出或縮回時，經常(chang)出現速度不均(jun)勻現象(xiang)，并(bing)有時伴有振動(dong)和異響，從而引(yin)起整個液(ye)壓(ya)系統的(de)振動(dong)，并(bing)帶(dai)動(dong)主機(ji)其(qi)它部件振動(dong)，在(zai)主機(ji)調試(shi)過程中(zhong)經常(chang)出現，有時速度快了，這(zhe)(zhe)種(zhong)現象(xiang)會減輕。除因(yin)液(ye)壓(ya)系統管路引(yin)起這(zhe)(zhe)種(zhong)現象(xiang)以外，液(ye)壓(ya)缸(gang)(gang)自身(shen)產生的(de)振動(dong)也經常(chang)引(yin)發此類現象(xiang)。
原因分析
液壓(ya)缸有(you)桿腔和無桿腔存有(you)氣體(ti)而產生的(de)低速(su)爬行，由于氣體(ti)混在液壓(ya)油中，在壓(ya)力的(de)作(zuo)用(yong)下(xia)(xia)，容器內(nei)體(ti)積變化，在高壓(ya)作(zuo)用(yong)下(xia)(xia)甚至發生氣體(ti)瞬間，從而引(yin)起液壓(ya)缸的(de)速(su)度不穩定。
