輪(lun)(lun)體(ti)、支(zhi)重(zhong)輪(lun)(lun)軸(zhou)、軸(zhou)套(tao)、密封圈、端蓋等相關部(bu)件構成。支(zhi)重(zhong)輪(lun)(lun)可分為單邊支(zhi)重(zhong)輪(lun)(lun)與雙邊支(zhi)重(zhong)輪(lun)(lun)；挖掘(jue)機(ji)用支(zhi)重(zhong)輪(lun)(lun)與推(tui)土(tu)機(ji)用支(zhi)重(zhong)輪(lun)(lun)，挖掘(jue)機(ji)用支(zhi)重(zhong)輪(lun)(lun)一般(ban)是黑色(se)油漆，推(tui)土(tu)機(ji)支(zhi)重(zhong)輪(lun)(lun)一般(ban)是黃色(se)油漆

支(zhi)重輪(lun)輪(lun)體材料(liao)(liao)一(yi)(yi)般(ban)50Mn、40Mn2、等材料(liao)(liao)，主要(yao)工藝鑄造(zao)或鍛(duan)造(zao)，機械(xie)加(jia)(jia)工，然后進(jin)行熱(re)處(chu)理，賀州四輪(lun)一(yi)(yi)帶(dai)，輪(lun)子表面(mian)淬火后的(de)(de)硬(ying)度要(yao)達到(dao)HRC45~52，以增加(jia)(jia)輪(lun)子表面(mian)的(de)(de)耐磨性(xing)。支(zhi)重輪(lun)軸的(de)(de)加(jia)(jia)工精(jing)度要(yao)求比較高，一(yi)(yi)般(ban)是(shi)需要(yao)數控機床進(jin)行加(jia)(jia)工才能達到(dao)要(yao)求。材料(liao)(liao)以40Mn2較多(duo)，求購四輪(lun)一(yi)(yi)帶(dai)，加(jia)(jia)工后也要(yao)進(jin)行淬火熱(re)處(chu)理，硬(ying)度達到(dao)HRC42左右(you)
