支重輪-徐工攤鋪機支重輪-中特工程廠家：

　支重輪“啃(ken)軌”的原因主要(yao)是：

　　（1）支重(zhong)輪固(gu)定螺(luo)栓松(song)動，造(zao)成支重(zhong)輪軸向位置變動或發生歪斜。

　　（2）支重(zhong)輪的(de)定(ding)位(wei)槽(cao)嚴(yan)重(zhong)磨損。

　　（3）臺車架(jia)固定支重輪的(de)一組孔(kong)的(de)中心(xin)線與(yu)半軸安裝孔(kong)、斜支撐安裝孔(kong)形(xing)成的(de)直線不(bu)(bu)垂直（空(kong)間不(bu)(bu)垂直）。

　　（4）支重輪(lun)的中間(jian)凸緣加工時產(chan)生了偏移。

　　（5）滾道母線(xian)與履(lv)(lv)帶銷(xiao)軸線(xian)不平行使履(lv)(lv)帶側滑。

　　（6）支重輪兩(liang)邊滾道(dao)直徑不同。

支重輪總成的采購

    支重輪是履帶式工程機械底盤四輪一帶中(zhong)的一種，它的主(zhu)要作用是支撐著挖(wa)掘機(ji)(ji)與推土機(ji)(ji)的重量，讓(rang)履帶沿著輪子(zi)前進。

支重輪的主要結構：

    輪(lun)(lun)(lun)體、支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun)軸、軸套(tao)、密封圈、端(duan)蓋等相(xiang)關部件構成(cheng)。支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun)可(ke)分為單邊支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun)與(yu)雙(shuang)邊支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun)；挖掘機用(yong)支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun)與(yu)推土(tu)機用(yong)支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun)，挖掘機用(yong)支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun)一般(ban)是(shi)黑色(se)油漆，推土(tu)機支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun)一般(ban)是(shi)黃色(se)油漆。

    支重輪主(zhu)要看它的(de)鋼材(cai)性能(neng)，支重輪輪體材(cai)料一般50Mn、40Ｍn２，（ＭＮ：猛元(yuan)素的(de)代(dai)名詞(ci)），制造工藝(yi)分為(wei)鑄造或者鍛造，機械加(jia)工，然后(hou)(hou)進行熱處理(li)，輪子(zi)表面淬火(huo)后(hou)(hou)的(de)硬度達(da)到(dao)(dao)HRC45~52，以增加(jia)輪子(zi)表面的(de)耐(nai)磨性。支重輪的(de)加(jia)工精度要求比較(jiao)高，一般是需要數(shu)控機床進行加(jia)工才(cai)能(neng)達(da)到(dao)(dao)要求。材(cai)料以40Ｍn２較(jiao)多，硬度達(da)到(dao)(dao)HRC42左右。

    支(zhi)(zhi)重輪(lun)(lun)的(de)結構主要(yao)(yao)分為輪(lun)(lun)體、支(zhi)(zhi)重輪(lun)(lun)軸、軸套、密(mi)封圈(quan)、端蓋(gai)，如(ru)果(guo)你(ni)所選(xuan)購(gou)(gou)(gou)(gou)的(de)支(zhi)(zhi)重輪(lun)(lun)的(de)支(zhi)(zhi)重輪(lun)(lun)軸、軸套的(de)硬度(du)是不達標的(de)產(chan)品，那(nei)就(jiu)會(hui)出(chu)現(xian)(xian)安裝后不到幾天就(jiu)漏油的(de)現(xian)(xian)象，建(jian)議(yi)每次購(gou)(gou)(gou)(gou)回來的(de)產(chan)品要(yao)(yao)細看它的(de)構造、品牌、價(jia)格和在(zai)哪家選(xuan)購(gou)(gou)(gou)(gou)的(de)做個記(ji)錄，如(ru)果(guo)不好用下(xia)次不要(yao)(yao)重復購(gou)(gou)(gou)(gou)買，購(gou)(gou)(gou)(gou)買時也可以與供貨商多(duo)聊一下(xia)質量方面的(de)問題，把你(ni)對產(chan)品的(de)要(yao)(yao)求告訴他，如(ru)果(guo)出(chu)現(xian)(xian)幾天就(jiu)漏油的(de)情況(kuang)應該(gai)如(ru)何(he)解(jie)決。

支重輪總成的材料

    支重輪(lun)(lun)主要看它的鋼材(cai)性(xing)能，支重輪(lun)(lun)輪(lun)(lun)體材(cai)料(liao)一(yi)(yi)般50Mn、40Ｍn２，（ＭＮ：猛元(yuan)素的代名詞），制造(zao)工藝分為鑄造(zao)或(huo)者鍛造(zao)，機(ji)械加(jia)(jia)工，然后進行熱(re)處理，輪(lun)(lun)子表面(mian)(mian)淬火后的硬(ying)度(du)達到(dao)(dao)HRC45~52，以增加(jia)(jia)輪(lun)(lun)子表面(mian)(mian)的耐磨性(xing)。支重輪(lun)(lun)的加(jia)(jia)工精度(du)要求(qiu)比較(jiao)高(gao)，一(yi)(yi)般是需要數控(kong)機(ji)床(chuang)進行加(jia)(jia)工才能達到(dao)(dao)要求(qiu)。材(cai)料(liao)以40Ｍn２較(jiao)多，硬(ying)度(du)達到(dao)(dao)HRC42左右。

    支重輪輪體材料(liao)一般(ban)50Mn、40Mn2、等材料(liao)，主(zhu)要(yao)工(gong)藝(yi)鑄造或鍛造，機械加工(gong)，然(ran)后(hou)(hou)進行(xing)(xing)熱處(chu)理，輪子表(biao)(biao)面(mian)淬(cui)火(huo)后(hou)(hou)的(de)硬度(du)要(yao)達(da)到(dao)HRC45~52，以(yi)增加輪子表(biao)(biao)面(mian)的(de)耐(nai)磨性(xing)。支重輪軸的(de)加工(gong)精(jing)度(du)要(yao)求比(bi)較高，一般(ban)是需要(yao)數控機床進行(xing)(xing)加工(gong)才(cai)能達(da)到(dao)要(yao)求。材料(liao)以(yi)40Mn2較多(duo)，加工(gong)后(hou)(hou)也要(yao)進行(xing)(xing)淬(cui)火(huo)熱處(chu)理，硬度(du)達(da)到(dao)HRC42左右(you)。
