湖北中特工程機械有限公司提醒您，關于支重輪的(de)結(jie)構布置：

      根(gen)據功(gong)率大(da)小，履(lv)帶(dai)推土機每側有(you)4～7個支(zhi)(zhi)(zhi)重(zhong)(zhong)輪(lun)(lun)(lun)(lun)(lun)的(de)功(gong)率小的(de)取(qu)下(xia)限，功(gong)率大(da)的(de)取(qu)上限。當履(lv)帶(dai)接(jie)地(di)長度(du)一(yi)定時(shi)，增(zeng)加支(zhi)(zhi)(zhi)重(zhong)(zhong)輪(lun)(lun)(lun)(lun)(lun)個數(shu)，可(ke)使接(jie)地(di)壓強均勻，減少履(lv)轍深度(du)金額(e)滾動(dong)阻力，但增(zeng)加個數(shu)后(hou)，勢(shi)必(bi)減少直徑，從而增(zeng)大(da)支(zhi)(zhi)(zhi)重(zhong)(zhong)輪(lun)(lun)(lun)(lun)(lun)在履(lv)軌上滾動(dong)的(de)阻力，綜合考(kao)慮這兩個因素，一(yi)般取(qu)支(zhi)(zhi)(zhi)重(zhong)(zhong)輪(lun)(lun)(lun)(lun)(lun)直徑Dz=（1～2.0）lt。各支(zhi)(zhi)(zhi)重(zhong)(zhong)輪(lun)(lun)(lun)(lun)(lun)等距分(fen)布，軸(zhou)間(jian)(jian)距lz=(1.7～2.0))lt,后(hou)端的(de)支(zhi)(zhi)(zhi)重(zhong)(zhong)輪(lun)(lun)(lun)(lun)(lun)軸(zhou)與驅動(dong)輪(lun)(lun)(lun)(lun)(lun)軸(zhou)之(zhi)間(jian)(jian)的(de)距離lk=(2.3～2.6)lt，的(de)支(zhi)(zhi)(zhi)重(zhong)(zhong)輪(lun)(lun)(lun)(lun)(lun)位(wei)置應保證(zheng)張緊(jin)輪(lun)(lun)(lun)(lun)(lun)調整到后(hou)極(ji)限位(wei)置而緩沖彈簧又壓縮達極(ji)大(da)值時(shi)不會發生干涉。驅動(dong)鏈輪(lun)(lun)(lun)(lun)(lun)齒頂與支(zhi)(zhi)(zhi)重(zhong)(zhong)輪(lun)(lun)(lun)(lun)(lun)輪(lun)(lun)(lun)(lun)(lun)轂(gu)之(zhi)間(jian)(jian)，應留有(you)足夠的(de)間(jian)(jian)隙，以防積泥。

支重輪的材料

    隨著我(wo)國公路(lu)等(deng)級(ji)趨向(xiang)多元化,等(deng)級(ji)公路(lu)、縣(xian)鄉公路(lu)及城(cheng)市道路(lu)均以的(de)(de)規模、標準和(he)速度(du)向(xiang)前推進。同時路(lu)面(mian)施(shi)(shi)(shi)工(gong)(gong)(gong)的(de)(de)速度(du)也在“飛速”的(de)(de)提高(gao),這樣(yang)在推動(dong)公路(lu)施(shi)(shi)(shi)工(gong)(gong)(gong)機械(xie)化的(de)(de)同時也對(dui)施(shi)(shi)(shi)工(gong)(gong)(gong)機械(xie)技(ji)術(shu)水平,施(shi)(shi)(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)和(he)路(lu)面(mian)材料及路(lu)面(mian)結(jie)構設(she)計提出了越(yue)來越(yue)高(gao)的(de)(de)要(yao)求。而施(shi)(shi)(shi)工(gong)(gong)(gong)機械(xie)技(ji)術(shu)水平和(he)施(shi)(shi)(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)對(dui)公路(lu)等(deng)級(ji)和(he)施(shi)(shi)(shi)工(gong)(gong)(gong)速度(du)有著重(zhong)要(yao)的(de)(de)影響。

支重輪材料是？

    答(da)：支(zhi)重輪(lun)輪(lun)體材料(liao)一(yi)般50Mn、40Mn2、等材料(liao)，主要(yao)(yao)工(gong)藝鑄造(zao)或鍛造(zao)，機械加工(gong)，然后(hou)進行(xing)熱(re)處(chu)理(li)，輪(lun)子表面淬火后(hou)的硬(ying)度(du)要(yao)(yao)達(da)到HRC45~52，以(yi)增加輪(lun)子表面的耐磨性。支(zhi)重輪(lun)軸的加工(gong)精(jing)度(du)要(yao)(yao)求比較(jiao)高(gao)，一(yi)般是需要(yao)(yao)數控機床(chuang)進行(xing)加工(gong)才能達(da)到要(yao)(yao)求。材料(liao)以(yi)40Mn2較(jiao)多，加工(gong)后(hou)也要(yao)(yao)進行(xing)淬火熱(re)處(chu)理(li)，硬(ying)度(du)達(da)到HRC42左右。

支重輪總成的結構特點

 .輪體：采用淬(cui)透性好的50Mn2圓鋼材料經鍛(duan)造(zao)而成(cheng)；調質+中頻表(biao)面(mian)淬(cui)火的熱處理工(gong)藝，表(biao)面(mian)硬(ying)度HRC55-60，硬(ying)化層深度可(ke)達6-8mm，保證其強度和耐磨性。
