擺動式液壓缸
擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)液壓缸(gang)是輸出扭矩并實(shi)現往復(fu)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)的執行(xing)元件，有單(dan)葉片(pian)(pian)、雙(shuang)葉片(pian)(pian)、螺(luo)(luo)旋(xuan)擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)等幾種形式(shi)。葉片(pian)(pian)式(shi)式(shi)：定(ding)子塊固定(ding)在(zai)缸(gang)體上，而葉片(pian)(pian)和轉子連接在(zai)一起。根據(ju)進油方向，葉片(pian)(pian)將帶動(dong)(dong)(dong)(dong)(dong)(dong)(dong)轉子作往復(fu)擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)。螺(luo)(luo)旋(xuan)擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)又分單(dan)螺(luo)(luo)旋(xuan)擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)和雙(shuang)螺(luo)(luo)旋(xuan)兩種，現在(zai)雙(shuang)螺(luo)(luo)旋(xuan)比較常用，靠兩個螺(luo)(luo)旋(xuan)副降液壓缸(gang)內活塞(sai)的直(zhi)線運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)轉變為直(zhi)線運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)與(yu)自轉運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)的復(fu)he運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)，從(cong)而實(shi)現擺(bai)(bai)(bai)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)。
有異(yi)物(wu)進入后，活塞滑(hua)(hua)動(dong)表面的(de)外側(ce)如(ru)裝(zhuang)有帶唇(chun)緣(yuan)的(de)密(mi)封件(jian)，那么，工作時密(mi)封件(jian)的(de)唇(chun)緣(yuan)即可刮動(dong)異(yi)物(wu)，這對于避免劃(hua)傷是有利的(de)。但(dan)是裝(zhuang)0形(xing)密(mi)封圈的(de)活塞，其兩(liang)端是滑(hua)(hua)動(dong)表面，異(yi)物(wu)夾在此滑(hua)(hua)動(dong)表面之間，容易形(xing)成傷痕(hen)。
異物進入缸(gang)內的途徑有下列幾(ji)種。
① 進(jin)入缸內的異物
a.由于保管(guan)時不注(zhu)意(yi)使油(you)口(kou)敞(chang)開著，將產(chan)生時刻接受異物的條件，這是不允(yun)許的。保管(guan)時必須注(zhu)入防銹油(you)或者工作油(you)液，并(bing)且塞(sai)好。
、液(ye)壓缸(gang)低速爬行的現(xian)象
液壓(ya)缸的(de)(de)活(huo)塞桿(gan)在油壓(ya)的(de)(de)作(zuo)用下伸(shen)出(chu)或縮回時(shi)，經(jing)常(chang)出(chu)現(xian)速度不均勻現(xian)象(xiang)(xiang)，并有時(shi)伴有振動和異響，從而引起整個(ge)液壓(ya)系統(tong)(tong)的(de)(de)振動，并帶動主機(ji)其它部件振動，在主機(ji)調試過(guo)程中經(jing)常(chang)出(chu)現(xian)，有時(shi)速度快了，這種現(xian)象(xiang)(xiang)會減輕。除因液壓(ya)系統(tong)(tong)管路引起這種現(xian)象(xiang)(xiang)以外，液壓(ya)缸自(zi)身產生(sheng)的(de)(de)振動也經(jing)常(chang)引發此類現(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)氣體而產生(sheng)(sheng)的低速爬行，由于氣體混在(zai)液壓(ya)油(you)中，在(zai)壓(ya)力的作(zuo)用(yong)下，容器內體積變化，在(zai)高壓(ya)作(zuo)用(yong)下甚(shen)至發生(sheng)(sheng)氣體瞬間(jian)，從而引起液壓(ya)缸(gang)的速度不穩定。
