中特工程機械(圖)-支重輪總成供應廠家-支重輪總成：

    支(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)的(de)(de)主要(yao)(yao)結構(gou)：輪(lun)(lun)體、支(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)軸(zhou)、軸(zhou)套、密封圈(quan)、端蓋等(deng)相(xiang)關部件(jian)構(gou)成。支(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)可分(fen)為單邊(bian)(bian)支(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)與雙(shuang)邊(bian)(bian)支(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)；挖掘(jue)(jue)機(ji)(ji)用(yong)支(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)與推(tui)土機(ji)(ji)用(yong)支(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)，挖掘(jue)(jue)機(ji)(ji)用(yong)支(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)一般是黑色油漆，推(tui)土機(ji)(ji)支(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)一般是黃色油漆。支(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)輪(lun)(lun)體材(cai)料(liao)一般45鋼、40Mn2、等(deng)材(cai)料(liao)，主要(yao)(yao)工(gong)藝鑄(zhu)造或鍛造，機(ji)(ji)械加(jia)工(gong)，然后(hou)進(jin)行熱處理(li)，輪(lun)(lun)子(zi)表面淬(cui)火后(hou)的(de)(de)硬度(du)(du)要(yao)(yao)達(da)(da)到(dao)HRC38左右，以增加(jia)輪(lun)(lun)子(zi)表面的(de)(de)耐磨性。支(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)軸(zhou)的(de)(de)加(jia)工(gong)精度(du)(du)要(yao)(yao)求(qiu)比較高(gao)，一般是需要(yao)(yao)數控機(ji)(ji)床(chuang)進(jin)行加(jia)工(gong)才能(neng)達(da)(da)到(dao)要(yao)(yao)求(qiu)。材(cai)料(liao)以40Mn2較多，加(jia)工(gong)后(hou)也(ye)要(yao)(yao)進(jin)行淬(cui)火熱處理(li)，硬度(du)(du)達(da)(da)到(dao)HRC42左右。

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(cong)90mm至228.6mm配套系列化，主(zhu)要代(dai)表性的(de)配套機型美(mei)國(guo)卡(ka)特(te)D4D、D6D/G、D9H/L、307、E200B、E450，日本小松PC60、PC100、PC200、PC300、PC400，現代(dai)R60、R80、R110、R150、R200、R225、R305，柳工CLG906、CLG200、CLG936、洛陽一拖(tuo)T90、T120、WY6、WY10等。

支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)(lun)的輪(lun)(lun)體、支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)(lun)軸(zhou)、軸(zhou)套(tao)、密(mi)封(feng)圈、端蓋等相(xiang)關部件構成。支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)(lun)可分(fen)為(wei)單邊支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)(lun)與雙(shuang)邊支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)(lun)；挖(wa)(wa)掘機(ji)用(yong)支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)(lun)與推(tui)土機(ji)用(yong)支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)(lun)，挖(wa)(wa)掘機(ji)用(yong)支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)(lun)一般是黑色(se)(se)油(you)漆(qi)，推(tui)土機(ji)支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)(lun)一般是黃色(se)(se)油(you)漆(qi)支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)(lun)作為(wei)履(lv)帶旋挖(wa)(wa)鉆(zhan)機(ji)的主要承載結構件，尤其是在大噸位履(lv)帶旋挖(wa)(wa)鉆(zhan) 機(ji)中，其設計(ji)和制(zhi)造質量(liang)直接關系著(zhu)鉆(zhan)機(ji)的整機(ji)安全性。支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)(lun)的輪(lun)(lun)體圓徑的減(jian)小(xiao) 變(bian)成輪(lun)(lun)子線(xian)速度加快(kuai)，軸(zhou)套(tao)承受的摩(mo)(mo)擦(ca)越多。支(zhi)(zhi)軸(zhou)變(bian)細(xi)道理也是一樣，同樣承受撞擊的力度也會不夠，照成軸(zhou)變(bian)形或者斷掉。 銅(tong)套(tao)起到摩(mo)(mo)擦(ca)作用(yong)，銅(tong)層(ceng)必須經(jing)過滾扎(zha)后才不易脫落，正(zheng)常得0.35mm以上銅(tong)層(ceng)才達標，減(jian)少銅(tong)套(tao)長度支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪(lun)(lun)的意義也就失(shi)去了作用(yong)，減(jian)少長度等同于減(jian)少受力面積。
