呼倫貝爾支重輪,中特重工(優質商家),攤鋪機支重輪：

摘要

拖(tuo)拉機在行駛(shi)作業(ye)中(zhong)．支(zhi)重(zhong)(zhong)臺車不僅要(yao)支(zhi)承著整臺拖(tuo)拉機的(de)重(zhong)(zhong)量．還要(yao)承受(shou)沖(chong)擊載荷．逐漸使(shi)其零件磨(mo)損或變(bian)形。當(dang)擺(bai)動軸(zhou)與平衡育(yu)小(xiao)軸(zhou)套磨(mo)損、配合間隙增大(da)、大(da)小(xiao)緩沖(chong)彈簧的(de)彈性(xing)變(bian)弱時(shi)．都(dou)會使(shi)每個支(zhi)重(zhong)(zhong)臺車上的(de)兩個支(zhi)重(zhong)(zhong)輪中(zhong)心距離變(bian)大(da)．使(shi)支(zhi)重(zhong)(zhong)臺車彈性(xing)是(shi)架的(de)緩沖(chong)和減(jian)震性(xing)能降低

湖北中特工程機械有限公司提醒您，關于支(zhi)重(zhong)輪的結構布(bu)置：

      根據功(gong)率大小，履帶(dai)(dai)推土機(ji)每側有(you)(you)4～7個支(zhi)(zhi)(zhi)重(zhong)輪(lun)(lun)，功(gong)率小的(de)(de)取(qu)下限(xian)，功(gong)率大的(de)(de)取(qu)上(shang)限(xian)。當履帶(dai)(dai)接(jie)地長度(du)一定時，增加支(zhi)(zhi)(zhi)重(zhong)輪(lun)(lun)個數，可使接(jie)地壓(ya)強均勻，減少履轍深度(du)金額滾動(dong)(dong)阻(zu)力，但增加個數后，勢必(bi)減少直徑，從而(er)增大支(zhi)(zhi)(zhi)重(zhong)輪(lun)(lun)在履軌上(shang)滾動(dong)(dong)的(de)(de)阻(zu)力，支(zhi)(zhi)(zhi)重(zhong)輪(lun)(lun)廠(chang)家 ，綜合考慮這(zhe)兩個因素，呼倫貝爾支(zhi)(zhi)(zhi)重(zhong)輪(lun)(lun)，一般取(qu)支(zhi)(zhi)(zhi)重(zhong)輪(lun)(lun)直徑Dz=（1～2.0）lt。各(ge)支(zhi)(zhi)(zhi)重(zhong)輪(lun)(lun)等距(ju)(ju)分(fen)布(bu)，挖(wa)掘(jue)機(ji)支(zhi)(zhi)(zhi)重(zhong)輪(lun)(lun)價格，軸(zhou)(zhou)間(jian)(jian)距(ju)(ju)lz=(1.7～2.0))lt，后端(duan)(duan)的(de)(de)支(zhi)(zhi)(zhi)重(zhong)輪(lun)(lun)軸(zhou)(zhou)與(yu)驅動(dong)(dong)輪(lun)(lun)軸(zhou)(zhou)之間(jian)(jian)的(de)(de)距(ju)(ju)離lk=(2.3～2.6)lt，前端(duan)(duan)的(de)(de)支(zhi)(zhi)(zhi)重(zhong)輪(lun)(lun)位置應保(bao)證張(zhang)緊(jin)輪(lun)(lun)調整到后極限(xian)位置而(er)緩(huan)沖(chong)彈簧又壓(ya)縮(suo)達極大值時不會發生干涉。驅動(dong)(dong)鏈輪(lun)(lun)齒(chi)頂與(yu)支(zhi)(zhi)(zhi)重(zhong)輪(lun)(lun)輪(lun)(lun)轂之間(jian)(jian)，應留(liu)有(you)(you)足夠的(de)(de)間(jian)(jian)隙，以防積泥。
