雖行業(ye)身處寒(han)冬，但(dan)(dan)每個行業(ye)、企業(ye)冷靜的(de)思考過后會發(fa)現，今天的(de)冬天就不會寒(han)冷。但(dan)(dan)是(shi)(shi)從更長(chang)遠來(lai)看未來(lai)五年，中(zhong)(zhong)國(guo)的(de)總量還會逐(zhu)步(bu)回(hui)(hui)升(sheng)，曾光安認(ren)為(wei)今天挖(wa)掘機已經在逐(zhu)步(bu)增長(chang)，希望一季(ji)度的(de)挖(wa)掘機增長(chang)不是(shi)(shi)短(duan)期的(de)，而是(shi)(shi)長(chang)期的(de)，比(bi)(bi)如(ru)兩會給國(guo)民增強(qiang)信心(xin)，很多大(da)型項目開工，資金到位，具體可能(neng)會有短(duan)期刺激，但(dan)(dan)是(shi)(shi)總體來(lai)講(jiang)，挖(wa)掘機今年見底甚至回(hui)(hui)升(sheng)我(wo)認(ren)為(wei)是(shi)(shi)大(da)概率事情。裝載機處在下降(jiang)通道，一季(ji)度仍然在下降(jiang)。中(zhong)(zhong)國(guo)未來(lai)五年內(nei)，逐(zhu)步(bu)會回(hui)(hui)升(sheng)到美(mei)國(guo)的(de)水(shui)平。我(wo)比(bi)(bi)較有信心(xin)，將又迎來(lai)第(di)二個高(gao)潮。

中國的經(jing)(jing)濟周期(qi)和歐美經(jing)(jing)濟周期(qi)相比，經(jing)(jing)濟周期(qi)有典型的中國特(te)色。我個人認為，2015年、2016年基本(ben)上是(shi)本(ben)輪經(jing)(jing)濟周期(qi)底(di)部(bu)，從本(ben)身經(jing)(jing)濟規(gui)律來看它應該是(shi)緩步回(hui)升(sheng)，春(chun)天即將來臨(lin)！

全(quan)(quan)球(qiu)經濟(ji)(ji)變化導致工程機(ji)械(xie)(xie)行業格局的(de)(de)(de)大變局：全(quan)(quan)球(qiu)市場經濟(ji)(ji)下滑、貨幣貶值、全(quan)(quan)球(qiu)貨幣價值重(zhong)構，這不光是對中國(guo)的(de)(de)(de)工程機(ji)械(xie)(xie)，對全(quan)(quan)球(qiu)所有產(chan)(chan)業都(dou)產(chan)(chan)生了(le)巨(ju)大影響。現在(zai)礦山設備(bei)就是災難性(xing)(xing)的(de)(de)(de)，工程機(ji)械(xie)(xie)大幅度萎縮，全(quan)(quan)球(qiu)性(xing)(xing)產(chan)(chan)能嚴重(zhong)過剩，全(quan)(quan)球(qiu)工程機(ji)械(xie)(xie)行業綜合性(xing)(xing)競爭(zheng)。裝載機(ji)企(qi)業，有的(de)(de)(de)產(chan)(chan)品價格打折打到三、四折賣，不同(tong)國(guo)家和(he)地(di)區的(de)(de)(de)制造商的(de)(de)(de)收入和(he)利潤不同(tong)程度地(di)下滑。不光我(wo)們(men)在(zai)座的(de)(de)(de)各位難受，國(guo)際(ji)同(tong)行，如歐洲、日本(ben)、韓國(guo)甚至(zhi)美國(guo)都(dou)遇到了(le)同(tong)樣的(de)(de)(de)問題

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的(de)(de)一種，它的(de)(de)主要作用是支撐著挖掘(jue)機(ji)與推土機(ji)的(de)(de)重量，讓履帶沿(yan)著輪子(zi)前進。

支重輪的主要結構：

    輪體、支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪軸、軸套、密封圈、端蓋等(deng)相關(guan)部件構(gou)成。支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪可分為單邊支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪與(yu)雙邊支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪；挖掘機用(yong)支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪與(yu)推土機用(yong)支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪，挖掘機用(yong)支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪一(yi)(yi)般是黑色油(you)漆，推土機支(zhi)(zhi)重(zhong)(zhong)(zhong)(zhong)輪一(yi)(yi)般是黃色油(you)漆。

    支(zhi)重(zhong)輪(lun)(lun)(lun)主要(yao)看它的(de)(de)鋼(gang)材性(xing)能(neng)(neng)，支(zhi)重(zhong)輪(lun)(lun)(lun)輪(lun)(lun)(lun)體材料一般(ban)(ban)50Mn、40Ｍn２，（ＭＮ：猛元(yuan)素的(de)(de)代名詞），制造工藝分為鑄造或者(zhe)鍛造，機械(xie)加(jia)(jia)工，然后進行熱處理，輪(lun)(lun)(lun)子(zi)(zi)表面淬火(huo)后的(de)(de)硬(ying)度(du)達(da)到(dao)HRC45~52，以增加(jia)(jia)輪(lun)(lun)(lun)子(zi)(zi)表面的(de)(de)耐(nai)磨性(xing)。支(zhi)重(zhong)輪(lun)(lun)(lun)的(de)(de)加(jia)(jia)工精(jing)度(du)要(yao)求(qiu)比較高，一般(ban)(ban)是(shi)需要(yao)數控機床(chuang)進行加(jia)(jia)工才能(neng)(neng)達(da)到(dao)要(yao)求(qiu)。材料以40Ｍn２較多，硬(ying)度(du)達(da)到(dao)HRC42左右(you)。

    支(zhi)重(zhong)輪(lun)的(de)(de)結構(gou)主要(yao)分為輪(lun)體、支(zhi)重(zhong)輪(lun)軸(zhou)(zhou)、軸(zhou)(zhou)套(tao)、密封(feng)圈(quan)、端(duan)蓋，如(ru)果(guo)你所選購的(de)(de)支(zhi)重(zhong)輪(lun)的(de)(de)支(zhi)重(zhong)輪(lun)軸(zhou)(zhou)、軸(zhou)(zhou)套(tao)的(de)(de)硬(ying)度(du)是不(bu)(bu)達標的(de)(de)產(chan)品(pin)，那就(jiu)會出現(xian)(xian)安裝后不(bu)(bu)到幾天就(jiu)漏油(you)的(de)(de)現(xian)(xian)象，建(jian)議每次購回來的(de)(de)產(chan)品(pin)要(yao)細(xi)看它的(de)(de)構(gou)造、品(pin)牌(pai)、價(jia)格和(he)在哪家選購的(de)(de)做個(ge)記(ji)錄，如(ru)果(guo)不(bu)(bu)好用下(xia)次不(bu)(bu)要(yao)重(zhong)復購買，購買時也(ye)可以(yi)與(yu)供貨商(shang)多聊一(yi)下(xia)質量方(fang)面(mian)的(de)(de)問題(ti)，把你對產(chan)品(pin)的(de)(de)要(yao)求告訴他，如(ru)果(guo)出現(xian)(xian)幾天就(jiu)漏油(you)的(de)(de)情況應該如(ru)何(he)解決。
