支重輪的材料

    隨(sui)著(zhu)(zhu)我國公路(lu)(lu)(lu)等(deng)(deng)級(ji)趨向(xiang)多元化，等(deng)(deng)級(ji)公路(lu)(lu)(lu)、縣鄉公路(lu)(lu)(lu)及(ji)城市道路(lu)(lu)(lu)均以前(qian)所(suo)未有(you)的(de)(de)(de)規模、標準和(he)速度向(xiang)前(qian)推(tui)進(jin)。同時(shi)路(lu)(lu)(lu)面(mian)施(shi)(shi)(shi)工(gong)(gong)的(de)(de)(de)速度也在“飛(fei)速”的(de)(de)(de)提高，大埔縣支(zhi)重輪，這樣(yang)在推(tui)動(dong)公路(lu)(lu)(lu)施(shi)(shi)(shi)工(gong)(gong)機械(xie)(xie)化的(de)(de)(de)同時(shi)也對(dui)(dui)施(shi)(shi)(shi)工(gong)(gong)機械(xie)(xie)技術(shu)水平(ping)，施(shi)(shi)(shi)工(gong)(gong)工(gong)(gong)藝和(he)路(lu)(lu)(lu)面(mian)材料及(ji)路(lu)(lu)(lu)面(mian)結構設(she)計提出了越(yue)來越(yue)高的(de)(de)(de)要(yao)求(qiu)。而(er)施(shi)(shi)(shi)工(gong)(gong)機械(xie)(xie)技術(shu)水平(ping)和(he)施(shi)(shi)(shi)工(gong)(gong)工(gong)(gong)藝對(dui)(dui)公路(lu)(lu)(lu)等(deng)(deng)級(ji)和(he)施(shi)(shi)(shi)工(gong)(gong)速度有(you)著(zhu)(zhu)重要(yao)的(de)(de)(de)影響(xiang)。

支重輪材料是？

    答：支重輪(lun)(lun)輪(lun)(lun)體材(cai)(cai)料一般50Mn、40Mn2、等材(cai)(cai)料，主要(yao)(yao)工(gong)(gong)(gong)(gong)藝鑄(zhu)造(zao)或鍛造(zao)，機械加(jia)(jia)工(gong)(gong)(gong)(gong)，然(ran)后進(jin)行熱處(chu)理(li)(li)，輪(lun)(lun)子表面(mian)(mian)淬火(huo)后的硬度(du)要(yao)(yao)達(da)到(dao)HRC45~52，以增(zeng)加(jia)(jia)輪(lun)(lun)子表面(mian)(mian)的耐磨(mo)性(xing)。支重輪(lun)(lun)軸的加(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)度(du)要(yao)(yao)求比(bi)較高(gao)，一般是需要(yao)(yao)數控(kong)機床進(jin)行加(jia)(jia)工(gong)(gong)(gong)(gong)才能達(da)到(dao)要(yao)(yao)求。材(cai)(cai)料以40Mn2較多，加(jia)(jia)工(gong)(gong)(gong)(gong)后也(ye)要(yao)(yao)進(jin)行淬火(huo)熱處(chu)理(li)(li)，挖掘機支重輪(lun)(lun)，硬度(du)達(da)到(dao)HRC42左(zuo)右。

支重輪總成

    支(zhi)重輪輪體材料(liao)一般50Mn、40Mn2、等材料(liao)，主要(yao)(yao)工藝鑄造或鍛造，機械(xie)加工，然后(hou)進(jin)行(xing)熱(re)處(chu)理，輪子(zi)表面淬火(huo)后(hou)的硬度要(yao)(yao)達到HRC45~52，以增(zeng)加輪子(zi)表面的耐磨性(xing)。支(zhi)重輪軸的加工精度要(yao)(yao)求(qiu)比較(jiao)高，挖掘機支(zhi)重輪廠(chang)家，一般是需要(yao)(yao)數控機床進(jin)行(xing)加工才(cai)能達到要(yao)(yao)求(qiu)。材料(liao)以40Mn2較(jiao)多，加工后(hou)也要(yao)(yao)進(jin)行(xing)淬火(huo)熱(re)處(chu)理，現代(dai)挖掘機支(zhi)重輪，硬度達到HRC42左右。

    湖北中特工(gong)(gong)(gong)程機(ji)(ji)械(xie)有限公司(si)主要(yao)產(chan)品是用于(yu)攤鋪機(ji)(ji)、推土(tu)機(ji)(ji)、挖掘機(ji)(ji)、銑(xian)刨機(ji)(ji)上的各(ge)種(zhong)支重(zhong)輪、引導輪、驅動(dong)輪、托鏈輪、履帶和漲緊(jin)油缸等配(pei)件，現為徐(xu)工(gong)(gong)(gong)、中聯(lian)重(zhong)科、徐(xu)工(gong)(gong)(gong)、柳工(gong)(gong)(gong)、國機(ji)(ji)重(zhong)工(gong)(gong)(gong)、江蘇谷登、沃(wo)得重(zhong)工(gong)(gong)(gong)、廣西開元(yuan)、四川邦立(li)、恒天(tian)九五重(zhong)工(gong)(gong)(gong)等國內大型工(gong)(gong)(gong)程機(ji)(ji)械(xie)企業(ye)(ye)配(pei)套產(chan)品，可(ke)廣泛用于(yu)農(nong)業(ye)(ye)、礦山、鐵路、公路、城鎮化(hua)建設等施工(gong)(gong)(gong)工(gong)(gong)(gong)程。
