擺動式液壓缸
擺(bai)(bai)(bai)動(dong)(dong)(dong)式液壓(ya)缸是輸出(chu)扭矩并實現(xian)往(wang)復(fu)(fu)運(yun)動(dong)(dong)(dong)的(de)執(zhi)行元件，有單(dan)葉(xie)(xie)片、雙葉(xie)(xie)片、螺旋(xuan)擺(bai)(bai)(bai)動(dong)(dong)(dong)等幾種(zhong)形式。葉(xie)(xie)片式式：定(ding)子塊固定(ding)在缸體(ti)上，而(er)葉(xie)(xie)片和轉子連(lian)接在一起。根據進油方向，葉(xie)(xie)片將帶(dai)動(dong)(dong)(dong)轉子作(zuo)往(wang)復(fu)(fu)擺(bai)(bai)(bai)動(dong)(dong)(dong)。螺旋(xuan)擺(bai)(bai)(bai)動(dong)(dong)(dong)式又分單(dan)螺旋(xuan)擺(bai)(bai)(bai)動(dong)(dong)(dong)和雙螺旋(xuan)兩(liang)種(zhong)，現(xian)在雙螺旋(xuan)比(bi)較(jiao)常用，靠兩(liang)個(ge)螺旋(xuan)副降液壓(ya)缸內活塞的(de)直線運(yun)動(dong)(dong)(dong)轉變為直線運(yun)動(dong)(dong)(dong)與自轉運(yun)動(dong)(dong)(dong)的(de)復(fu)(fu)he運(yun)動(dong)(dong)(dong)，從而(er)實現(xian)擺(bai)(bai)(bai)動(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)。
液壓缸(gang)結構基本上可以(yi)分為缸(gang)筒(tong)和(he)缸(gang)蓋、活(huo)塞和(he)活(huo)塞桿、密封裝置、緩沖(chong)裝置和(he)排氣(qi)裝置五個部分。今(jin)天威海力建(jian)小編著重帶著大家了(le)解一下(xia)缸(gang)筒(tong)和(he)缸(gang)蓋。
缸(gang)(gang)筒和缸(gang)(gang)蓋
一般來(lai)說(shuo)，缸筒(tong)(tong)和(he)(he)(he)缸蓋的(de)(de)(de)結(jie)構形(xing)(xing)(xing)式(shi)和(he)(he)(he)其使(shi)用(yong)(yong)(yong)(yong)的(de)(de)(de)材料有關。工(gong)(gong)作壓力p＜10MPa時，使(shi)用(yong)(yong)(yong)(yong)鑄(zhu)鐵(tie)；p＜20MPa時，使(shi)用(yong)(yong)(yong)(yong)無縫鋼(gang)管；p＞20MPa時，使(shi)用(yong)(yong)(yong)(yong)鑄(zhu)鋼(gang)或(huo)鍛鋼(gang)。法蘭連(lian)接(jie)(jie)式(shi)，結(jie)構簡單，容(rong)(rong)易加工(gong)(gong)，也(ye)容(rong)(rong)易裝拆(chai)(chai)，但(dan)外形(xing)(xing)(xing)尺寸(cun)和(he)(he)(he)重(zhong)(zhong)(zhong)量(liang)都(dou)較大(da)，常用(yong)(yong)(yong)(yong)于鑄(zhu)鐵(tie)制的(de)(de)(de)缸筒(tong)(tong)上(shang)(shang)。半環連(lian)接(jie)(jie)式(shi)，它(ta)(ta)的(de)(de)(de)缸筒(tong)(tong)壁部因開(kai)了環形(xing)(xing)(xing)槽而削弱了強度(du)，為此有時要(yao)加厚缸壁，它(ta)(ta)容(rong)(rong)易加工(gong)(gong)和(he)(he)(he)裝拆(chai)(chai)，重(zhong)(zhong)(zhong)量(liang)較輕(qing)，常用(yong)(yong)(yong)(yong)于無縫鋼(gang)管或(huo)鍛鋼(gang)制的(de)(de)(de)缸筒(tong)(tong)上(shang)(shang)。螺紋連(lian)接(jie)(jie)式(shi)，它(ta)(ta)的(de)(de)(de)缸筒(tong)(tong)端部結(jie)構復雜，外徑加工(gong)(gong)時要(yao)求保證內外徑同心(xin)，裝拆(chai)(chai)要(yao)使(shi)用(yong)(yong)(yong)(yong)工(gong)(gong)具，它(ta)(ta)的(de)(de)(de)外形(xing)(xing)(xing)尺寸(cun)和(he)(he)(he)重(zhong)(zhong)(zhong)量(liang)都(dou)較小，常用(yong)(yong)(yong)(yong)于無縫鋼(gang)管或(huo)鑄(zhu)鋼(gang)制的(de)(de)(de)缸筒(tong)(tong)上(shang)(shang)。拉桿連(lian)接(jie)(jie)式(shi)，結(jie)構的(de)(de)(de)通用(yong)(yong)(yong)(yong)性大(da)，容(rong)(rong)易加工(gong)(gong)和(he)(he)(he)裝拆(chai)(chai)，但(dan)外形(xing)(xing)(xing)尺寸(cun)較大(da)，且較重(zhong)(zhong)(zhong)。焊接(jie)(jie)連(lian)接(jie)(jie)式(shi)，結(jie)構簡單，尺寸(cun)小，但(dan)缸底處內徑不(bu)易加工(gong)(gong)，且可能引起變形(xing)(xing)(xing)。
、液壓缸低速爬行(xing)的現象
液(ye)壓(ya)缸的(de)(de)活塞桿在(zai)油(you)壓(ya)的(de)(de)作用下伸出或(huo)縮回時，經常(chang)出現速度不均勻現象(xiang)(xiang)，并(bing)有時伴有振(zhen)動(dong)和(he)異響(xiang)，從而引(yin)起整個液(ye)壓(ya)系(xi)統(tong)的(de)(de)振(zhen)動(dong)，并(bing)帶(dai)動(dong)主機(ji)其(qi)它部件振(zhen)動(dong)，在(zai)主機(ji)調試過程(cheng)中(zhong)經常(chang)出現，有時速度快(kuai)了，這(zhe)種現象(xiang)(xiang)會減輕。除因(yin)液(ye)壓(ya)系(xi)統(tong)管路(lu)引(yin)起這(zhe)種現象(xiang)(xiang)以外，液(ye)壓(ya)缸自身產(chan)生的(de)(de)振(zhen)動(dong)也經常(chang)引(yin)發此類(lei)現象(xiang)(xiang)。
原因分析
液(ye)壓(ya)缸有(you)桿(gan)腔和無桿(gan)腔存(cun)有(you)氣體(ti)而產生的(de)低速爬(pa)行，由(you)于(yu)氣體(ti)混在液(ye)壓(ya)油中，在壓(ya)力的(de)作用下(xia)，容器內體(ti)積變化，在高壓(ya)作用下(xia)甚(shen)至發生氣體(ti)瞬(shun)間，從(cong)而引起(qi)液(ye)壓(ya)缸的(de)速度不穩定。
