擺動式液壓缸
擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)(shi)(shi)液壓缸(gang)是(shi)輸出扭矩并實(shi)現往復運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)執行(xing)元件，有單葉(xie)(xie)片(pian)(pian)、雙(shuang)葉(xie)(xie)片(pian)(pian)、螺旋(xuan)(xuan)(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)等(deng)幾種形式(shi)(shi)(shi)。葉(xie)(xie)片(pian)(pian)式(shi)(shi)(shi)式(shi)(shi)(shi)：定子(zi)塊固定在(zai)缸(gang)體上，而(er)葉(xie)(xie)片(pian)(pian)和轉(zhuan)子(zi)連接(jie)在(zai)一起。根據進油方向，葉(xie)(xie)片(pian)(pian)將(jiang)帶(dai)動(dong)(dong)(dong)(dong)(dong)(dong)轉(zhuan)子(zi)作往復擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)。螺旋(xuan)(xuan)(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)(shi)(shi)又(you)分單螺旋(xuan)(xuan)(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)和雙(shuang)螺旋(xuan)(xuan)(xuan)兩(liang)種，現在(zai)雙(shuang)螺旋(xuan)(xuan)(xuan)比較常用，靠兩(liang)個螺旋(xuan)(xuan)(xuan)副降液壓缸(gang)內活塞的(de)直線(xian)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)轉(zhuan)變為直線(xian)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)與自轉(zhuan)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)復he運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)，從而(er)實(shi)現擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)。
采(cai)用滾(gun)(gun)(gun)壓(ya)加工，由(you)于(yu)表(biao)(biao)(biao)面(mian)層留有(you)表(biao)(biao)(biao)面(mian)殘余壓(ya)應力(li)(li)，有(you)助于(yu)表(biao)(biao)(biao)面(mian)微小(xiao)(xiao)裂(lie)紋(wen)的(de)封(feng)閉，阻礙侵蝕作用的(de)擴展。從(cong)而提(ti)(ti)(ti)高表(biao)(biao)(biao)面(mian)抗(kang)腐蝕能力(li)(li)，并能延(yan)緩疲(pi)勞裂(lie)紋(wen)的(de)產(chan)生或擴大，因(yin)而提(ti)(ti)(ti)高缸筒疲(pi)勞強度。通過滾(gun)(gun)(gun)壓(ya)成型，滾(gun)(gun)(gun)壓(ya)表(biao)(biao)(biao)面(mian)形成一層冷作硬化層，減(jian)少了磨削副接觸表(biao)(biao)(biao)面(mian)的(de)彈性(xing)(xing)和塑性(xing)(xing)變形，從(cong)而提(ti)(ti)(ti)高了缸筒內壁的(de)耐磨性(xing)(xing)，同時避(bi)免了因(yin)磨削引(yin)起的(de)shao傷。滾(gun)(gun)(gun)壓(ya)后，表(biao)(biao)(biao)面(mian)粗糙度值(zhi)的(de)減(jian)小(xiao)(xiao)，可提(ti)(ti)(ti)高配合性(xing)(xing)質。
若(ruo)溢(yi)流(liu)(liu)閥(fa)進(jin)入臟物卡住(zhu)閥(fa)芯，使溢(yi)流(liu)(liu)閥(fa)常開，液壓(ya)(ya)油(you)會(hui)經溢(yi)流(liu)(liu)閥(fa)旁通直接流(liu)(liu)回油(you)箱，導致液壓(ya)(ya)缸沒油(you)進(jin)入。若(ruo)負載過大，溢(yi)流(liu)(liu)閥(fa)的調節壓(ya)(ya)力(li)(li)雖(sui)已達到(dao)極大額定值，但液壓(ya)(ya)缸仍得不(bu)(bu)到(dao)連續動作(zuo)所(suo)需的推力(li)(li)而不(bu)(bu)動作(zuo)。若(ruo)調節壓(ya)(ya)力(li)(li)較低(di)，則(ze)因壓(ya)(ya)力(li)(li)不(bu)(bu)足(zu)達不(bu)(bu)到(dao)仍載所(suo)需的椎力(li)(li)，表現(xian)為推力(li)(li)不(bu)(bu)夠。此時(shi)應檢(jian)查(cha)并調整溢(yi)流(liu)(liu)閥(fa)。(威海力(li)(li)建冶金液壓(ya)(ya)設備(bei)廠(chang))
