    机械设计技术基础:拖链运(yun)动设计

    发布时(shi)间:2021/4/6 15:53:27

    机(ji)(ji)床(chuang)运(yun)动部(bu)件(jian)经常需(xu)要电(dian)(dian)(dian)(dian)缆、管路跟随运(yun)动,在运(yun)动中,管路、电(dian)(dian)(dian)(dian)缆需(xu)要保护及固定运(yun)动线路。机(ji)(ji)床(chuang)拖(tuo)链(lian)是用来保护机(ji)(ji)床(chuang)电(dian)(dian)(dian)(dian)缆油(you)(you)管气(qi)管用的(de),按(an)材(cai)质它分为(wei)钢铝(lv)拖(tuo)链(lian)和(he)工程塑料(liao)拖(tuo)链(lian),按(an)结构(gou)来分,有半封闭式(在外边可以(yi)看到(dao)电(dian)(dian)(dian)(dian)缆等(deng))和(he)全封闭(外边看不到(dao)电(dian)(dian)(dian)(dian)缆等(deng)),拖(tuo)链(lian)外形似坦克链(lian),由众多(duo)单元(yuan)链(lian)节组(zu)成,链(lian)节之间(jian)转动自如。弯曲(qu)半径(jing):选择(ze)内(nei)置电(dian)(dian)(dian)(dian)缆.油(you)(you)管、气(qi)管、水管等(deng)中***的(de)弯曲(qu)半径(jing)作为(wei)对(dui)(dui)考值并留有10%以(yi)上(shang)的(de)空间(jian)拖(tuo)链(lian)内(nei)置电(dian)(dian)(dian)(dian)缆、油(you)(you)管、水管、气(qi)管的(de)放置原则应该(gai)留有15%的(de)剩余空间(jian),让内(nei)置电(dian)(dian)(dian)(dian)缆、油(you)(you)管等(deng)可以(yi)******,在半径(jing)方向上(shang)对(dui)(dui)拖(tuo)链(lian)不产生拉力(li)。在设计(ji)时需(xu)要模拟其运(yun)动,防(fang)止安装匹配是出现(xian)干涉而无法装配。链(lian)节由左右(you)链(lian)板(ban)和(he)上(shang)下盖(gai)板(ban)组(zu)成,拖(tuo)链(lian)每(mei)节都能打开,装拆方便,不必穿线,打开盖(gai)板(ban)后即可把电(dian)(dian)(dian)(dian)缆、油(you)(you)管、气(qi)管等(deng)放入拖(tuo)链(lian)内(nei)。
