支重輪的材料

    隨著我國公路(lu)等(deng)級趨向(xiang)多元化，鎮江支重輪，等(deng)級公路(lu)、縣鄉公路(lu)及城市道路(lu)均以前(qian)所未有的(de)(de)規模、標準和(he)速(su)度向(xiang)前(qian)推進。同時路(lu)面(mian)(mian)施(shi)工(gong)(gong)(gong)的(de)(de)速(su)度也在(zai)“飛(fei)速(su)”的(de)(de)提(ti)高，這(zhe)樣在(zai)推動公路(lu)施(shi)工(gong)(gong)(gong)機械(xie)(xie)化的(de)(de)同時也對(dui)施(shi)工(gong)(gong)(gong)機械(xie)(xie)技術水平，卡(ka)特推土機支重輪，施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝和(he)路(lu)面(mian)(mian)材(cai)料及路(lu)面(mian)(mian)結(jie)構設(she)計提(ti)出了越來越高的(de)(de)要求。而施(shi)工(gong)(gong)(gong)機械(xie)(xie)技術水平和(he)施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝對(dui)公路(lu)等(deng)級和(he)施(shi)工(gong)(gong)(gong)速(su)度有著重要的(de)(de)影響。

支重輪材料是？

    答(da)：支重(zhong)輪(lun)(lun)輪(lun)(lun)體材料一(yi)般50Mn、40Mn2、等材料，ec210支重(zhong)輪(lun)(lun)，主要工藝鑄(zhu)造(zao)或鍛造(zao)，機(ji)械加(jia)工，然(ran)后(hou)進(jin)行(xing)熱處(chu)理，挖機(ji)支重(zhong)輪(lun)(lun)價格，輪(lun)(lun)子(zi)表(biao)面淬火后(hou)的硬度(du)(du)要達(da)到(dao)HRC45~52，以增(zeng)加(jia)輪(lun)(lun)子(zi)表(biao)面的耐磨性。支重(zhong)輪(lun)(lun)軸的加(jia)工精度(du)(du)要求比較(jiao)高，一(yi)般是需要數控機(ji)床(chuang)進(jin)行(xing)加(jia)工才能達(da)到(dao)要求。材料以40Mn2較(jiao)多，加(jia)工后(hou)也(ye)要進(jin)行(xing)淬火熱處(chu)理，硬度(du)(du)達(da)到(dao)HRC42左右。

摘要

拖(tuo)拉機在行駛作業中．支(zhi)重(zhong)(zhong)臺(tai)車不僅要支(zhi)承著整臺(tai)拖(tuo)拉機的(de)重(zhong)(zhong)量(liang)．還(huan)要承受(shou)沖擊載荷．逐漸使(shi)其(qi)零件磨損或變(bian)(bian)形。當擺動(dong)軸與平衡育小軸套磨損、配合(he)間隙增大(da)、大(da)小緩沖彈簧的(de)彈性變(bian)(bian)弱(ruo)時．都會(hui)使(shi)每個支(zhi)重(zhong)(zhong)臺(tai)車上的(de)兩個支(zhi)重(zhong)(zhong)輪(lun)中心距(ju)離變(bian)(bian)大(da)．使(shi)支(zhi)重(zhong)(zhong)臺(tai)車彈性是架的(de)緩沖和(he)減震性能降低
