寧河縣挖掘機支重輪、中特重工(優質商家)、挖掘機支重輪規格：

支重輪作用：支重輪(lun)用(yong)螺釘固定在輪(lun)架下面(mian)，挖掘(jue)機支重輪(lun)廠家，用于支撐機械的質量，并將質量分(fen)布(bu)在履帶(dai)板上。同時還(huan)依靠(kao)其滾輪凸緣夾(jia)持鏈軌(gui)不使履帶(dai)橫向滑(hua)脫（脫軌(gui)），保證機械沿履帶(dai)方(fang)向運(yun)動(dong)‘具(ju)有較小的(de)滾動(dong)阻(zu)力以及泥濘(ning)和水中(zhong)作業時具(ju)有的(de)壽命。

湖北中特工程機械有限公司主要產品為履帶式工程機械底盤四輪一帶漲緊裝置等易損零部件，實現節距從90mm至228.6mm配套系列化，主要代表性的配套機型美國卡特D4D、D6D/G、D9H/L、307、E200B、E450，日本小松PC60、PC100、PC200、PC300、PC400，現代R60、R80、R110、R150、R200、R225、R305，柳工CLG906、CLG200、CLG936、洛陽一拖T90、T120、WY6、WY10等。產品主要配套主機生產廠(chang)商：中聯重(zhong)科、徐工、柳工、國機重(zhong)工、江蘇谷登、沃得重(zhong)工、廣西開(kai)元、四川邦立、恒天(tian)九五重(zhong)工等。

支重輪總成的材料

    優質支(zhi)重(zhong)輪(lun)(lun)主要看它(ta)的(de)(de)鋼材性能(neng)，支(zhi)重(zhong)輪(lun)(lun)輪(lun)(lun)體材料一般50Mn、40Ｍn２，（ＭＮ：猛(meng)元(yuan)素的(de)(de)代名詞），制造(zao)工藝分為鑄造(zao)或者鍛(duan)造(zao)，機械加(jia)(jia)(jia)工，寧河縣挖掘機支(zhi)重(zhong)輪(lun)(lun)，然后進行(xing)熱處理(li)，輪(lun)(lun)子表面(mian)淬火后的(de)(de)硬度(du)達(da)到HRC45~52，以(yi)增加(jia)(jia)(jia)輪(lun)(lun)子表面(mian)的(de)(de)耐磨(mo)性。支(zhi)重(zhong)輪(lun)(lun)的(de)(de)加(jia)(jia)(jia)工精(jing)度(du)要求(qiu)比較(jiao)高，挖掘機支(zhi)重(zhong)輪(lun)(lun)規格，一般是需要數控(kong)機床進行(xing)加(jia)(jia)(jia)工才能(neng)達(da)到要求(qiu)。材料以(yi)40Ｍn２較(jiao)多，硬度(du)達(da)到HRC42左右。

    支重輪(lun)輪(lun)體材料一(yi)般50Mn、40Mn2、等材料，主(zhu)要(yao)工(gong)藝鑄造或鍛(duan)造，機(ji)械加工(gong)，然后進(jin)行(xing)熱處理，輪(lun)子表面(mian)淬火(huo)后的硬度要(yao)達到(dao)HRC45~52，以增(zeng)加輪(lun)子表面(mian)的耐(nai)磨(mo)性。支重輪(lun)軸(zhou)的加工(gong)精度要(yao)求比(bi)較高(gao)，挖掘機(ji)支重輪(lun)圖紙，一(yi)般是需要(yao)數控機(ji)床進(jin)行(xing)加工(gong)才能(neng)達到(dao)要(yao)求。材料以40Mn2較多，加工(gong)后也要(yao)進(jin)行(xing)淬火(huo)熱處理，硬度達到(dao)HRC42左右。
