擺動式液壓缸
擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)液(ye)(ye)壓(ya)缸是(shi)輸出扭矩并實(shi)現(xian)(xian)往(wang)復運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)執行(xing)元件，有單葉片(pian)、雙(shuang)葉片(pian)、螺(luo)旋(xuan)(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)等幾種形(xing)式(shi)。葉片(pian)式(shi)式(shi)：定(ding)子(zi)(zi)塊(kuai)固定(ding)在(zai)(zai)缸體上，而(er)(er)葉片(pian)和(he)轉(zhuan)(zhuan)子(zi)(zi)連接(jie)在(zai)(zai)一(yi)起。根據進油(you)方(fang)向，葉片(pian)將帶動(dong)(dong)(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)子(zi)(zi)作(zuo)往(wang)復擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)。螺(luo)旋(xuan)(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)又分單螺(luo)旋(xuan)(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)雙(shuang)螺(luo)旋(xuan)(xuan)兩種，現(xian)(xian)在(zai)(zai)雙(shuang)螺(luo)旋(xuan)(xuan)比較常用(yong)，靠兩個(ge)螺(luo)旋(xuan)(xuan)副降液(ye)(ye)壓(ya)缸內活塞的(de)直線運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)變為直線運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)與自轉(zhuan)(zhuan)運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)復he運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)，從而(er)(er)實(shi)現(xian)(xian)擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)。
采用滾(gun)壓(ya)加工，由(you)于表(biao)(biao)面(mian)(mian)(mian)(mian)層留有(you)表(biao)(biao)面(mian)(mian)(mian)(mian)殘余壓(ya)應力，有(you)助(zhu)于表(biao)(biao)面(mian)(mian)(mian)(mian)微小(xiao)裂紋的(de)(de)封閉，阻礙侵蝕(shi)作(zuo)(zuo)用的(de)(de)擴(kuo)展。從(cong)而提(ti)(ti)高表(biao)(biao)面(mian)(mian)(mian)(mian)抗腐蝕(shi)能(neng)力，并能(neng)延緩疲(pi)勞(lao)裂紋的(de)(de)產生或擴(kuo)大，因(yin)(yin)而提(ti)(ti)高缸筒疲(pi)勞(lao)強度。通過(guo)滾(gun)壓(ya)成型，滾(gun)壓(ya)表(biao)(biao)面(mian)(mian)(mian)(mian)形成一層冷(leng)作(zuo)(zuo)硬(ying)化層，減(jian)少了磨(mo)削(xue)副接觸(chu)表(biao)(biao)面(mian)(mian)(mian)(mian)的(de)(de)彈性(xing)和塑性(xing)變形，從(cong)而提(ti)(ti)高了缸筒內壁(bi)的(de)(de)耐磨(mo)性(xing)，同時避免了因(yin)(yin)磨(mo)削(xue)引起的(de)(de)shao傷。滾(gun)壓(ya)后，表(biao)(biao)面(mian)(mian)(mian)(mian)粗糙度值(zhi)的(de)(de)減(jian)小(xiao)，可(ke)提(ti)(ti)高配合性(xing)質。
(5)液壓(ya)缸(gang)初始動作(zuo)緩慢。在(zai)溫(wen)(wen)度較低(di)的(de)情況下，液壓(ya)油黏(nian)度大，流動性差，導(dao)致液壓(ya)缸(gang)動作(zuo)緩慢。改善方法是，更換黏(nian)溫(wen)(wen)性能較好的(de)液壓(ya)油，在(zai)低(di)溫(wen)(wen)下可(ke)借助加熱器(qi)(qi)或用機(ji)器(qi)(qi)自身加熱以提升啟動時(shi)的(de)油溫(wen)(wen)，系(xi)統正常工作(zuo)油溫(wen)(wen)應保持在(zai)40℃左右。
2、工作(zuo)時不(bu)能驅動負載(zai)
主要表現(xian)為活塞桿停位(wei)不準、推力不足、速度(du)下降(jiang)、工作不穩定等,其(qi)原因是：
