制(zhi)动器(qi)知识

起重机制动器的作用

来源:http://impnow.com/news/132.html添加时间:2015-01-10

    对于(yu)起重机而言,制动器的(de)使用是非常重要的(de),那么它的(de)作用有(you)哪(na)些,它的(de)组成(cheng)和工作原理是什么?

    起(qi)重机械的(de)(de)(de)(de)各机构中,起(qi)重机制(zhi)动器是(shi)用来保证起(qi)重机能准确、可靠和安全运(yun)行的(de)(de)(de)(de)重要部(bu)件。起(qi)升(sheng)机构的(de)(de)(de)(de)制(zhi)动装(zhuang)置(zhi)(zhi)保证了吊物停(ting)(ting)止(zhi)(zhi)位置(zhi)(zhi),并(bing)且(qie)在(zai)起(qi)升(sheng)机构停(ting)(ting)止(zhi)(zhi)运(yun)行后能使(shi)吊物保持在(zai)该位置(zhi)(zhi),起(qi)到阻止(zhi)(zhi)重物下落(luo)的(de)(de)(de)(de)作用。运(yun)行机构及其他机构的(de)(de)(de)(de)制(zhi)动装(zhuang)置(zhi)(zhi)除用来实现停(ting)(ting)车(che)及保持在(zai)停(ting)(ting)留位置(zhi)(zhi)外,在(zai)某(mou)些特殊(shu)情况(kuang)下,还可根(gen)据工作需(xu)要实现降低或调节机构运(yun)行速度。

    起重机制(zhi)(zhi)动(dong)(dong)(dong)(dong)装置(zhi)通(tong)(tong)常由(you)制(zhi)(zhi)动(dong)(dong)(dong)(dong)器(qi)、制(zhi)(zhi)动(dong)(dong)(dong)(dong)轮和制(zhi)(zhi)动(dong)(dong)(dong)(dong)驱动(dong)(dong)(dong)(dong)装置(zhi)组成。包括调整(zheng)(zheng)工(gong)作行程、调整(zheng)(zheng)制(zhi)(zhi)动(dong)(dong)(dong)(dong)力(li)(li)(li)矩、调整(zheng)(zheng)制(zhi)(zhi)动(dong)(dong)(dong)(dong)间隙三(san)个(ge)方面的(de)调整(zheng)(zheng)工(gong)作。它是通(tong)(tong)过摩(mo)擦(ca)(ca)原(yuan)理来实现(xian)机构制(zhi)(zhi)动(dong)(dong)(dong)(dong)的(de)。当设(she)置(zhi)在(zai)静止(zhi)机座上(shang)的(de)制(zhi)(zhi)动(dong)(dong)(dong)(dong)器(qi)的(de)摩(mo)擦(ca)(ca)部件以(yi)一定的(de)作用力(li)(li)(li)压(ya)向机构中某一运行转轴上(shang)的(de)被(bei)摩(mo)擦(ca)(ca)部件时,这(zhei)两接触(chu)而(er)间产(chan)生(sheng)的(de)摩(mo)擦(ca)(ca)力(li)(li)(li)对(dui)转动(dong)(dong)(dong)(dong)轴线(xian)产(chan)生(sheng)了摩(mo)擦(ca)(ca)力(li)(li)(li)矩,这(zhei)个(ge)力(li)(li)(li)矩通(tong)(tong)常称(cheng)为制(zhi)(zhi)动(dong)(dong)(dong)(dong)力(li)(li)(li)矩。当制(zhi)(zhi)动(dong)(dong)(dong)(dong)力(li)(li)(li)矩与吊(diao)物重量(liang)或运行时的(de)惯性力(li)(li)(li)产(chan)生(sheng)的(de)力(li)(li)(li)矩相(xiang)平衡时,即达到了制(zhi)(zhi)动(dong)(dong)(dong)(dong)要求。
