支重輪-中特工程-現代挖掘機支重輪：

湖北中特工程機械有限公司提醒您，關于支重輪容(rong)易出現在問題(ti)是：

A、輪體磨(mo)損。出現這種情況的(de)原因是采用的(de)鋼材(cai)不合(he)格或者說(shuo)材(cai)料熱處(chu)理時(shi)的(de)硬度較低，耐磨(mo)性不足；

B、漏油(you)(you)。支(zhi)重輪(lun)軸(zhou)通過軸(zhou)套(tao)(tao)一直在旋(xuan)轉，輪(lun)體內要(yao)加油(you)(you)來潤滑(hua)，但如果(guo)說密封圈不好(hao)的(de)(de)話，很(hen)容易產(chan)生漏油(you)(you)的(de)(de)現象，這樣軸(zhou)與軸(zhou)套(tao)(tao)在無潤滑(hua)的(de)(de)情(qing)況下，很(hen)容易磨損，造成產(chan)品(pin)無法進行使(shi)用。

因此，支重(zhong)輪密(mi)封(feng)的好壞是作(zuo)為衡量(liang)生產公(gong)司產品質量(liang)的一個很重(zhong)要的標(biao)準。

湖北中特工程機械有限公司，成立于2009年，位于湖北咸寧市咸安經濟開發區，注冊資金1000萬元，專業技術人員23名，員工220名，廠區占地70畝。公司承襲湖北咸寧工程機械股份有限公司幾十年技術積累，擁有先進的生產、檢測設備，依靠技術和科學管理，產品與國內外成功企業對接，是從事履帶式工程機械底盤和液壓件研發、制造和銷售的專業型企業。產品銷售(shou)覆蓋國內，積極參與國際(ji)市(shi)場競爭(zheng)。

支重輪的設計方法

   作為攤鋪機腿部配件(jian)的(de)(de)一員——支(zhi)重(zhong)輪(lun)，是不(bu)可或(huo)缺的(de)(de)。支(zhi)重(zhong)輪(lun)，是由輪(lun)體、支(zhi)重(zhong)輪(lun)軸(zhou)(zhou)、軸(zhou)(zhou)套(tao)、密封圈、端蓋等(deng)相關部件(jian)構成(cheng)的(de)(de)。

 ;  支重(zhong)輪(lun)可以(yi)分(fen)為單邊支重(zhong)輪(lun)與雙(shuang)邊支重(zhong)輪(lun)；挖掘機用(yong)(yong)(yong)支重(zhong)輪(lun)以(yi)及推土機用(yong)(yong)(yong)支重(zhong)輪(lun)，挖掘機用(yong)(yong)(yong)支重(zhong)輪(lun)一般是(shi)黑色油漆的，推土機支重(zhong)輪(lun)一般是(shi)黃色油漆的。

    湖北中特工(gong)程機械(xie)有限公(gong)司(si)的的產品主要適(shi)用于3.0~120噸級的履帶式工(gong)程機械(xie)（挖(wa)掘(jue)機、攤鋪(pu)機、旋挖(wa)機、強夯機、潛孔鉆(zhan)機、履帶吊、水平定向鉆(zhan)、銑(xian)刨機、破碎機等(deng)）

    中特公司主要生產：90、101.6、135、140、154.2、171.45、175、190、202.8、215.9、216、228.6、260.35mm系列節距的106個機型、300個品種的工程機械“四輪一帶”和漲緊裝置。

支重輪總成的材料

    支(zhi)重輪(lun)(lun)主要看(kan)它的(de)鋼材(cai)性(xing)能，支(zhi)重輪(lun)(lun)輪(lun)(lun)體材(cai)料一般(ban)50Mn、40Ｍn２，（ＭＮ：猛元(yuan)素的(de)代(dai)名詞），制造(zao)工藝分為鑄(zhu)造(zao)或者鍛(duan)造(zao)，機械加(jia)(jia)工，然后進行熱(re)處(chu)理，輪(lun)(lun)子表面淬火后的(de)硬(ying)度達(da)到HRC45~52，以(yi)增加(jia)(jia)輪(lun)(lun)子表面的(de)耐磨性(xing)。支(zhi)重輪(lun)(lun)的(de)加(jia)(jia)工精度要求比較高，一般(ban)是需要數控機床進行加(jia)(jia)工才能達(da)到要求。材(cai)料以(yi)40Ｍn２較多(duo)，硬(ying)度達(da)到HRC42左右。

    支(zhi)重輪輪體(ti)材(cai)料(liao)一般50Mn、40Mn2、等(deng)材(cai)料(liao)，主要(yao)工(gong)藝鑄造(zao)或(huo)鍛造(zao)，機械(xie)加(jia)工(gong)，然后(hou)進(jin)行(xing)熱處(chu)(chu)理(li)，輪子表面(mian)(mian)淬(cui)火(huo)后(hou)的(de)硬度(du)要(yao)達(da)到(dao)HRC45~52，以增(zeng)加(jia)輪子表面(mian)(mian)的(de)耐磨性。支(zhi)重輪軸的(de)加(jia)工(gong)精度(du)要(yao)求比(bi)較(jiao)(jiao)高(gao)，一般是(shi)需要(yao)數控機床(chuang)進(jin)行(xing)加(jia)工(gong)才能達(da)到(dao)要(yao)求。材(cai)料(liao)以40Mn2較(jiao)(jiao)多，加(jia)工(gong)后(hou)也要(yao)進(jin)行(xing)淬(cui)火(huo)熱處(chu)(chu)理(li)，硬度(du)達(da)到(dao)HRC42左右。
