擺動式液壓缸
擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)式(shi)液壓缸是(shi)輸出扭矩(ju)并實現往(wang)復(fu)運(yun)動(dong)(dong)(dong)(dong)(dong)的執行(xing)元件，有單葉(xie)片(pian)(pian)(pian)、雙葉(xie)片(pian)(pian)(pian)、螺(luo)旋擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)等(deng)幾(ji)種形式(shi)。葉(xie)片(pian)(pian)(pian)式(shi)式(shi)：定子(zi)塊固定在缸體上(shang)，而(er)葉(xie)片(pian)(pian)(pian)和轉(zhuan)(zhuan)子(zi)連(lian)接在一起。根據進油方向，葉(xie)片(pian)(pian)(pian)將帶(dai)動(dong)(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)子(zi)作(zuo)往(wang)復(fu)擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)。螺(luo)旋擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)式(shi)又分單螺(luo)旋擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)和雙螺(luo)旋兩種，現在雙螺(luo)旋比(bi)較(jiao)常用，靠兩個螺(luo)旋副(fu)降液壓缸內活(huo)塞的直線運(yun)動(dong)(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)變(bian)為直線運(yun)動(dong)(dong)(dong)(dong)(dong)與自轉(zhuan)(zhuan)運(yun)動(dong)(dong)(dong)(dong)(dong)的復(fu)he運(yun)動(dong)(dong)(dong)(dong)(dong)，從(cong)而(er)實現擺(bai)(bai)動(dong)(dong)(dong)(dong)(dong)運(yun)動(dong)(dong)(dong)(dong)(dong)。
孔(kong)的表面硬度提高(gao)(gao)約(yue)30%，缸(gang)筒(tong)內表面疲勞強度提高(gao)(gao)25%。油缸(gang)使(shi)用(yong)壽命(ming)若(ruo)只考慮缸(gang)筒(tong)影(ying)響，提高(gao)(gao)2～3倍，鏜削滾壓(ya)工藝(yi)較磨削工藝(yi)效率提高(gao)(gao)3倍左右。以上數據說明，滾壓(ya)工藝(yi)是高(gao)(gao)xiao的，能大大提高(gao)(gao)缸(gang)筒(tong)的表面質量(liang)。
油缸經過滾壓后(hou)，表面沒有鋒利的微小刃口，長時(shi)間的運動(dong)摩擦也不會損(sun)傷密封圈或密封件，這(zhe)一點在(zai)液壓行業特別(bie)的重(zhong)要。
O形密(mi)封(feng)圈(quan)在(zai)低壓下(xia)使用時(shi)，與U形密(mi)封(feng)圈(quan)比較，由(you)于面(mian)壓較高、動靜(jing)摩(mo)擦阻力(li)(li)之差較大(da)，容易產生滑(hua)移或爬(pa)(pa)行(xing)；U型密(mi)封(feng)圈(quan)的面(mian)壓隨著壓力(li)(li)的提高而增(zeng)大(da)，雖然密(mi)封(feng)效果(guo)也相應提高，但(dan)動靜(jing)摩(mo)擦阻力(li)(li)之差也變大(da)，內壓增(zeng)加(jia)，影(ying)響橡膠彈性，由(you)于唇(chun)緣(yuan)的接觸(chu)阻力(li)(li)增(zeng)大(da)，密(mi)封(feng)圈(quan)將會傾翻及唇(chun)緣(yuan)伸(shen)長，也容易引起滑(hua)移或爬(pa)(pa)行(xing)，為防止(zhi)其傾翻可采(cai)用支承環保持其穩定(ding)。
