擺動式液壓缸
擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)液(ye)壓缸(gang)(gang)是輸出扭(niu)矩(ju)并實現往(wang)復運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的執行元件(jian)，有(you)單葉片、雙葉片、螺(luo)旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)等(deng)幾種形(xing)式(shi)。葉片式(shi)式(shi)：定(ding)子塊固定(ding)在缸(gang)(gang)體上，而(er)葉片和(he)(he)轉(zhuan)(zhuan)子連接在一起。根(gen)據進油方向，葉片將帶動(dong)(dong)(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)子作往(wang)復擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)。螺(luo)旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)又分單螺(luo)旋(xuan)擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)(he)雙螺(luo)旋(xuan)兩(liang)種，現在雙螺(luo)旋(xuan)比較(jiao)常(chang)用，靠兩(liang)個螺(luo)旋(xuan)副(fu)降液(ye)壓缸(gang)(gang)內(nei)活塞的直線運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)變為(wei)直線運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)與自轉(zhuan)(zhuan)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的復he運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)，從而(er)實現擺(bai)動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)。
緩沖裝置
在液(ye)壓(ya)系統中使用液(ye)壓(ya)缸(gang)(gang)驅(qu)動具有(you)一定(ding)質量的機構，當液(ye)壓(ya)缸(gang)(gang)運動至行程終(zhong)點時具有(you)較大(da)動能，如未(wei)作減速處理，液(ye)壓(ya)缸(gang)(gang)活塞(sai)與(yu)缸(gang)(gang)蓋(gai)將發(fa)生機械碰撞(zhuang)，產(chan)生沖(chong)擊、噪聲，有(you)破(po)壞性。為緩和及防止(zhi)這(zhe)種危害發(fa)生，因(yin)此可在液(ye)壓(ya)回路中設(she)置減速裝置或在缸(gang)(gang)體內(nei)設(she)緩沖(chong)裝置。
加工
缸(gang)(gang)筒(tong)作為液(ye)壓缸(gang)(gang)、礦用單體支(zhi)柱、液(ye)壓支(zhi)架、炮管(guan)等產品(pin)的主要部件(jian)，其加(jia)(jia)工(gong)質量(liang)的好(hao)壞直(zhi)接(jie)影響整個(ge)產品(pin)的壽命和(he)可靠(kao)性(xing)(xing)。缸(gang)(gang)筒(tong)加(jia)(jia)工(gong)要求(qiu)高，其內表面粗糙度(du)要求(qiu)為Ra0.4～0.8&um，對同軸度(du)、耐磨性(xing)(xing)要求(qiu)嚴(yan)格。缸(gang)(gang)筒(tong)的基本特征是(shi)深孔加(jia)(jia)工(gong)，其加(jia)(jia)工(gong)一直(zhi)困擾加(jia)(jia)工(gong)人員。
一般地說，測(ce)量(liang)時造(zao)成(cheng)深度(du)不(bu)(bu)(bu)大(da)的(de)(de)細長形劃傷是(shi)輕微的(de)(de)，不(bu)(bu)(bu)影(ying)響運(yun)行精度(du)，但如果(guo)測(ce)量(liang)桿頭(tou)尺寸調(diao)(diao)節(jie)不(bu)(bu)(bu)當(dang)，測(ce)量(liang)觸(chu)頭(tou)硬行嵌入，會(hui)(hui)造(zao)成(cheng)較為重度(du)的(de)(de)傷痕(hen)。解決此(ci)問題的(de)(de)對策，首先是(shi)測(ce)量(liang)出(chu)調(diao)(diao)節(jie)好的(de)(de)測(ce)量(liang)頭(tou)的(de)(de)長短度(du)，此(ci)外，用(yong)一張只在測(ce)量(liang)位(wei)置上開孔的(de)(de)紙帶，貼在缸壁內表(biao)面，即(ji)不(bu)(bu)(bu)會(hui)(hui)產生上述形狀劃痕(hen)。測(ce)量(liang)造(zao)成(cheng)的(de)(de)輕微劃痕(hen)，一般用(yong)舊(jiu)砂布的(de)(de)反面或馬糞紙即(ji)可(ke)擦去。
