　液壓傳動在機械(xie)中(zhong)詳細的(de)應用

　　驅動(dong)(dong)機械運動(dong)(dong)的(de)(de)(de)機構以(yi)及各種傳(chuan)動(dong)(dong)和操(cao)縱(zong)裝置有(you)多(duo)種形(xing)式(shi)。根(gen)據所用(yong)的(de)(de)(de)部件和零件，可(ke)分(fen)為(wei)機械的(de)(de)(de)、電氣的(de)(de)(de)、氣動(dong)(dong)的(de)(de)(de)、液(ye)(ye)壓的(de)(de)(de)傳(chuan)動(dong)(dong)裝置。經(jing)常還(huan)將(jiang)不(bu)同的(de)(de)(de)形(xing)式(shi)組合起來(lai)運用(yong)——四位一體(ti)。由于(yu)液(ye)(ye)壓傳(chuan)動(dong)(dong)具有(you)很多(duo)優點，使這種新技(ji)(ji)術(shu)發展得(de)很快。液(ye)(ye)壓傳(chuan)動(dong)(dong)應(ying)用(yong)于(yu)金(jin)屬切削機床也不(bu)過四五十年(nian)(nian)的(de)(de)(de)歷史。航(hang)空工(gong)業(ye)在1930年(nian)(nian)以(yi)后(hou)才開(kai)始采用(yong)。特別(bie)是(shi)最(zui)近(jin)二三十年(nian)(nian)以(yi)來(lai)液(ye)(ye)壓技(ji)(ji)術(shu)在各種工(gong)業(ye)中的(de)(de)(de)應(ying)用(yong)越來(lai)越廣泛。

　　在機床上，液壓傳(chuan)動常應用在以(yi)下的(de)一(yi)些(xie)裝(zhuang)置中：

　　1.進給(gei)運動(dong)(dong)(dong)(dong)傳動(dong)(dong)(dong)(dong)裝置磨(mo)床(chuang)(chuang)砂輪架和工作(zuo)臺的(de)(de)進給(gei)運動(dong)(dong)(dong)(dong)大部分采(cai)用液壓(ya)傳動(dong)(dong)(dong)(dong)；車(che)床(chuang)(chuang)、六角車(che)床(chuang)(chuang)、自動(dong)(dong)(dong)(dong)車(che)床(chuang)(chuang)的(de)(de)刀架或轉塔刀架；銑床(chuang)(chuang)、刨床(chuang)(chuang)、組合機床(chuang)(chuang)的(de)(de)工作(zuo)臺等的(de)(de)進給(gei)運動(dong)(dong)(dong)(dong)也(ye)都采(cai)用液壓(ya)傳動(dong)(dong)(dong)(dong)。這(zhe)些(xie)部件有(you)(you)(you)(you)(you)的(de)(de)要(yao)(yao)(yao)求(qiu)(qiu)快速(su)移動(dong)(dong)(dong)(dong)，有(you)(you)(you)(you)(you)的(de)(de)要(yao)(yao)(yao)求(qiu)(qiu)慢(man)速(su)移動(dong)(dong)(dong)(dong)。有(you)(you)(you)(you)(you)的(de)(de)則(ze)既要(yao)(yao)(yao)求(qiu)(qiu)快速(su)移動(dong)(dong)(dong)(dong)，也(ye)要(yao)(yao)(yao)求(qiu)(qiu)慢(man)速(su)移動(dong)(dong)(dong)(dong)。這(zhe)些(xie)運動(dong)(dong)(dong)(dong)多半要(yao)(yao)(yao)求(qiu)(qiu)有(you)(you)(you)(you)(you)較大的(de)(de)調速(su)范圍(wei)，要(yao)(yao)(yao)求(qiu)(qiu)在工作(zuo)中無級調速(su)；有(you)(you)(you)(you)(you)的(de)(de)要(yao)(yao)(yao)求(qiu)(qiu)持續(xu)進給(gei)，有(you)(you)(you)(you)(you)的(de)(de)要(yao)(yao)(yao)求(qiu)(qiu)間歇進給(gei)；有(you)(you)(you)(you)(you)的(de)(de)要(yao)(yao)(yao)求(qiu)(qiu)在負載(zai)變化下速(su)度恒定，有(you)(you)(you)(you)(you)的(de)(de)要(yao)(yao)(yao)求(qiu)(qiu)有(you)(you)(you)(you)(you)良好的(de)(de)換(huan)向性能等等。所有(you)(you)(you)(you)(you)這(zhe)些(xie)要(yao)(yao)(yao)求(qiu)(qiu)都是可以用液壓(ya)傳動(dong)(dong)(dong)(dong)來實現的(de)(de)。

　　2.往(wang)復主體(ti)運(yun)動傳動裝(zhuang)置龍門刨床的工作臺、牛(niu)頭刨床或插床的滑枕(zhen)，由于(yu)要(yao)求(qiu)作高速往(wang)復直線運(yun)動，并(bing)且要(yao)求(qiu)換(huan)向(xiang)沖擊(ji)小、換(huan)向(xiang)時間短、能耗低，因此都(dou)可以采用(yong)液(ye)壓傳動。

　　3.仿(fang)形裝置(zhi)車床、銑床、刨床上(shang)的(de)仿(fang)形加工可(ke)以采(cai)用液壓(ya)伺服系統來(lai)完成。 其精度可(ke)達0.01～0.02mm。此外(wai)，磨床上(shang)的(de)成形砂輪修正裝置(zhi)亦可(ke)采(cai)用這種系統。

　　4.輔助裝(zhuang)(zhuang)置(zhi)機(ji)床(chuang)(chuang)上(shang)的夾緊裝(zhuang)(zhuang)置(zhi)、齒輪箱變速操縱裝(zhuang)(zhuang)置(zhi)、絲桿(gan)螺母間隙消除裝(zhuang)(zhuang)置(zhi)、垂(chui)直移(yi)動(dong)部(bu)件(jian)平衡裝(zhuang)(zhuang)置(zhi)、分度裝(zhuang)(zhuang)置(zhi)、工件(jian)和刀具裝(zhuang)(zhuang)卸(xie)裝(zhuang)(zhuang)置(zhi)、工件(jian)輸送裝(zhuang)(zhuang)置(zhi)等，采用液壓(ya)傳動(dong)后，有利于簡化機(ji)床(chuang)(chuang)結構，提高機(ji)床(chuang)(chuang)自動(dong)化程度。

　　5.靜壓(ya)支(zhi)承重型機(ji)(ji)(ji)(ji)床、高(gao)速機(ji)(ji)(ji)(ji)床、高(gao)精度機(ji)(ji)(ji)(ji)床上的軸承、導軌、絲(si)杠螺母(mu)機(ji)(ji)(ji)(ji)構等處采用液體靜壓(ya)支(zhi)承后(hou)，可以提(ti)高(gao)工(gong)作平(ping)穩性和運動精度。
