擺動式液壓缸
擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)式(shi)液壓缸(gang)是輸(shu)出扭矩并實(shi)現往(wang)復(fu)(fu)運(yun)動(dong)(dong)(dong)(dong)的執行元件，有單葉(xie)片(pian)、雙(shuang)葉(xie)片(pian)、螺(luo)旋擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)等幾(ji)種(zhong)形式(shi)。葉(xie)片(pian)式(shi)式(shi)：定(ding)子塊固(gu)定(ding)在(zai)缸(gang)體上，而(er)葉(xie)片(pian)和轉子連接(jie)在(zai)一起。根據進油方向，葉(xie)片(pian)將帶動(dong)(dong)(dong)(dong)轉子作(zuo)往(wang)復(fu)(fu)擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)。螺(luo)旋擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)式(shi)又(you)分單螺(luo)旋擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)和雙(shuang)螺(luo)旋兩種(zhong)，現在(zai)雙(shuang)螺(luo)旋比較常用，靠兩個螺(luo)旋副(fu)降(jiang)液壓缸(gang)內活(huo)塞的直線運(yun)動(dong)(dong)(dong)(dong)轉變為直線運(yun)動(dong)(dong)(dong)(dong)與(yu)自(zi)轉運(yun)動(dong)(dong)(dong)(dong)的復(fu)(fu)he運(yun)動(dong)(dong)(dong)(dong)，從而(er)實(shi)現擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)(dong)。
液壓(ya)缸(gang)結構基本上可以分為缸(gang)筒(tong)和缸(gang)蓋、活塞和活塞桿、密封(feng)裝置、緩沖裝置和排(pai)氣裝置五個(ge)部分。今天威海力建小編著重帶著大家了(le)解一下缸(gang)筒(tong)和缸(gang)蓋。
缸筒和(he)缸蓋(gai)
一般來說，缸(gang)(gang)筒(tong)和(he)(he)(he)缸(gang)(gang)蓋的(de)(de)(de)結(jie)(jie)構(gou)(gou)(gou)形(xing)(xing)(xing)式和(he)(he)(he)其使(shi)(shi)(shi)用(yong)(yong)(yong)的(de)(de)(de)材(cai)料(liao)有關。工(gong)(gong)作壓力(li)p＜10MPa時(shi)，使(shi)(shi)(shi)用(yong)(yong)(yong)鑄(zhu)鐵；p＜20MPa時(shi)，使(shi)(shi)(shi)用(yong)(yong)(yong)無(wu)縫(feng)鋼(gang)(gang)管；p＞20MPa時(shi)，使(shi)(shi)(shi)用(yong)(yong)(yong)鑄(zhu)鋼(gang)(gang)或(huo)鍛(duan)鋼(gang)(gang)。法蘭連(lian)接(jie)(jie)式，結(jie)(jie)構(gou)(gou)(gou)簡單(dan)，容易(yi)(yi)加工(gong)(gong)，也容易(yi)(yi)裝(zhuang)(zhuang)拆(chai)，但外形(xing)(xing)(xing)尺寸和(he)(he)(he)重量(liang)都(dou)(dou)較(jiao)大，常用(yong)(yong)(yong)于(yu)鑄(zhu)鐵制(zhi)的(de)(de)(de)缸(gang)(gang)筒(tong)上。半(ban)環(huan)連(lian)接(jie)(jie)式，它(ta)的(de)(de)(de)缸(gang)(gang)筒(tong)壁部(bu)因開(kai)了環(huan)形(xing)(xing)(xing)槽而(er)削弱了強度，為此有時(shi)要(yao)加厚缸(gang)(gang)壁，它(ta)容易(yi)(yi)加工(gong)(gong)和(he)(he)(he)裝(zhuang)(zhuang)拆(chai)，重量(liang)較(jiao)輕，常用(yong)(yong)(yong)于(yu)無(wu)縫(feng)鋼(gang)(gang)管或(huo)鍛(duan)鋼(gang)(gang)制(zhi)的(de)(de)(de)缸(gang)(gang)筒(tong)上。螺紋連(lian)接(jie)(jie)式，它(ta)的(de)(de)(de)缸(gang)(gang)筒(tong)端(duan)部(bu)結(jie)(jie)構(gou)(gou)(gou)復雜，外徑(jing)加工(gong)(gong)時(shi)要(yao)求保證內外徑(jing)同心，裝(zhuang)(zhuang)拆(chai)要(yao)使(shi)(shi)(shi)用(yong)(yong)(yong)工(gong)(gong)具，它(ta)的(de)(de)(de)外形(xing)(xing)(xing)尺寸和(he)(he)(he)重量(liang)都(dou)(dou)較(jiao)小，常用(yong)(yong)(yong)于(yu)無(wu)縫(feng)鋼(gang)(gang)管或(huo)鑄(zhu)鋼(gang)(gang)制(zhi)的(de)(de)(de)缸(gang)(gang)筒(tong)上。拉(la)桿連(lian)接(jie)(jie)式，結(jie)(jie)構(gou)(gou)(gou)的(de)(de)(de)通用(yong)(yong)(yong)性大，容易(yi)(yi)加工(gong)(gong)和(he)(he)(he)裝(zhuang)(zhuang)拆(chai)，但外形(xing)(xing)(xing)尺寸較(jiao)大，且較(jiao)重。焊接(jie)(jie)連(lian)接(jie)(jie)式，結(jie)(jie)構(gou)(gou)(gou)簡單(dan)，尺寸小，但缸(gang)(gang)底處內徑(jing)不易(yi)(yi)加工(gong)(gong)，且可能引起(qi)變(bian)形(xing)(xing)(xing)。
、液壓缸低速爬行的現象
液(ye)壓(ya)(ya)缸(gang)(gang)的活塞桿在油(you)壓(ya)(ya)的作用下(xia)伸出或(huo)縮回(hui)時，經(jing)常(chang)(chang)出現(xian)(xian)(xian)速度不均勻現(xian)(xian)(xian)象，并有(you)時伴(ban)有(you)振(zhen)(zhen)(zhen)動和(he)異響，從而引(yin)起整個液(ye)壓(ya)(ya)系(xi)統(tong)的振(zhen)(zhen)(zhen)動，并帶動主(zhu)機(ji)其它(ta)部件振(zhen)(zhen)(zhen)動，在主(zhu)機(ji)調試過程(cheng)中經(jing)常(chang)(chang)出現(xian)(xian)(xian)，有(you)時速度快了，這(zhe)種(zhong)現(xian)(xian)(xian)象會(hui)減輕(qing)。除因液(ye)壓(ya)(ya)系(xi)統(tong)管路引(yin)起這(zhe)種(zhong)現(xian)(xian)(xian)象以外，液(ye)壓(ya)(ya)缸(gang)(gang)自身產(chan)生(sheng)的振(zhen)(zhen)(zhen)動也經(jing)常(chang)(chang)引(yin)發此類(lei)現(xian)(xian)(xian)象。
原因分析
液壓缸有桿(gan)(gan)腔和無桿(gan)(gan)腔存(cun)有氣(qi)(qi)體(ti)而產(chan)生(sheng)的低速(su)爬(pa)行，由于氣(qi)(qi)體(ti)混在液壓油中，在壓力的作用下(xia)，容器內體(ti)積變化(hua)，在高壓作用下(xia)甚至(zhi)發生(sheng)氣(qi)(qi)體(ti)瞬間，從而引起液壓缸的速(su)度(du)不穩(wen)定。
