电力液压制动器在国内的发展

来源:http://impnow.com/news/290.html添加时间:2018-09-08

电(dian)力液压(ya)制动(dong)器是(shi)采用电(dian)力与液压(ya)相(xiang)结(jie)合的(de)(de)方式,使机械(xie)设(she)备(bei)停止运行的(de)(de)部件,非常(chang)(chang)适合于机械(xie)设(she)备(bei)上,对(dui)于机械(xie)设(she)备(bei)的(de)(de)正常(chang)(chang)工作(zuo)起到了非常(chang)(chang)大的(de)(de)作(zuo)用。


电(dian)力(li)液压制(zhi)动器采用退距自动均等(deng)、自动润滑等(deng)国(guo)内******结(jie)构(gou)装置(zhi),减少(shao)安装、调整、维(wei)修的工(gong)作量,提高主机生(sheng)产效率。具有安全、可靠、节约电(dian)能等(deng)优势(shi)。


多年(nian)来,国内制动(dong)(dong)(dong)(dong)器(qi)产品制动(dong)(dong)(dong)(dong)衬(chen)垫(dian)的(de)固(gu)定方式(shi)(shi)一直采(cai)用(yong)铆接(jie)式(shi)(shi)和压板组(zu)装式(shi)(shi)。铆接(jie)式(shi)(shi)连接(jie)费时又不省(sheng)材,压板组(zu)装式(shi)(shi)连接(jie)虽然(ran)维修更换方便,但制动(dong)(dong)(dong)(dong)衬(chen)垫(dian)利(li)用(yong)率低、浪(lang)费严重。电力液(ye)压制动(dong)(dong)(dong)(dong)器(qi)制动(dong)(dong)(dong)(dong)衬(chen)垫(dian)的(de)固(gu)定采(cai)用(yong)插入式(shi)(shi)连接(jie),克服了制动(dong)(dong)(dong)(dong)衬(chen)垫(dian)的(de)轴间窜动(dong)(dong)(dong)(dong),省(sheng)略(lve)了挡板,不但更换维修方便,而且(qie)制动(dong)(dong)(dong)(dong)器(qi)衬(chen)垫(dian)的(de)利(li)用(yong)率可提高30%,并且(qie)减少了固(gu)定中的(de)一些(xie)零件,省(sheng)材、省(sheng)时。


几(ji)十年来,国内(nei)制动(dong)(dong)器退(tui)距调(diao)整装(zhuang)(zhuang)置(zhi)基本(ben)上有两种,一是靠顶(ding)丝限位(wei)(wei),这种装(zhuang)(zhuang)置(zhi)在制动(dong)(dong)臂打(da)开(kai)(kai)时,需反复(fu)对(dui)两边顶(ding)丝调(diao)整,以保证两边退(tui)距大(da)(da)致均等(deng)(deng),而且在打(da)开(kai)(kai)时,冲击力较大(da)(da)。若(ruo)制动(dong)(dong)器安(an)装(zhuang)(zhuang)自(zi)动(dong)(dong)补偿机(ji)构(gou)时,制动(dong)(dong)衬垫磨损期间,需不(bu)断地对(dui)其(qi)装(zhuang)(zhuang)置(zhi)进(jin)行调(diao)整,否则,此靠顶(ding)丝限位(wei)(wei)装(zhuang)(zhuang)置(zhi)失效。二是弹簧限位(wei)(wei),这种装(zhuang)(zhuang)置(zhi)调(diao)整麻烦,结构(gou)复(fu)杂(za)。国外******国家(jia)制动(dong)(dong)器产品也具有等(deng)(deng)退(tui)距装(zhuang)(zhuang)置(zhi)机(ji)构(gou),但结构(gou)形式(shi)是将(jiang)等(deng)(deng)退(tui)距装(zhuang)(zhuang)置(zhi)的左(zuo)右(you)连板分别与左(zuo)右(you)制动(dong)(dong)臂铸(zhu)成一体,其(qi)铸(zhu)造(zao)结构(gou)复(fu)杂(za)、加(jia)工繁(fan)琐,难度大(da)(da)。
