支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun) 作用(yong)：支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun)用(yong)螺釘固定在(zai)輪(lun)(lun)(lun)架(jia)下面，用(yong)于支(zhi)(zhi)撐機械的(de)質量，并將質量分布在(zai)履(lv)(lv)帶(dai)板(ban)上(shang)。同時還依靠其滾(gun)輪(lun)(lun)(lun)凸緣夾持鏈(lian)軌不使履(lv)(lv)帶(dai)橫向滑脫（脫軌），保證(zheng)機械沿履(lv)(lv)帶(dai)方向運動(dong)‘具有(you)較小的(de)滾(gun)動(dong)阻(zu)力以及泥濘和水中作業時具有(you)的(de)壽(shou)命(ming)。支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun)按結構可分為單(dan)邊支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun)和雙邊支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun)。采(cai)用(yong)滑動(dong)軸承和滾(gun)動(dong)軸承兩類(lei)。支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun)緣都經過淬(cui)火，其硬度(du)達355—440 HB。在(zai)臺車架(jia)中，特別(bie)是為提高剛度(du)而裝置(zhi)隔(ge)板(ban)時，形成(cheng)的(de)一(yi)(yi)些(xie)空腔容易被泥土堵塞而阻(zu)礙支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun)轉動(dong)；在(zai)浸泡的(de)土壤上(shang)運行時，也容易堵塞支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun)。因此，有(you)一(yi)(yi)些(xie)履(lv)(lv)帶(dai)式推(tui)土機，在(zai)臺車架(jia)外側裝有(you)帶(dai)加(jia)強筋的(de)支(zhi)(zhi)重(zhong)(zhong)(zhong)輪(lun)(lun)(lun)護板(ban)。

支重輪總成的材料

    支重(zhong)輪主要(yao)看它(ta)的(de)鋼材性能，支重(zhong)輪輪體材料一般50Mn、40Ｍn２，（ＭＮ：猛元(yuan)素的(de)代名詞），制造工(gong)藝分為鑄造或者鍛造，機械加(jia)工(gong)，然后(hou)進行熱處理，輪子表面(mian)淬火后(hou)的(de)硬度(du)達到HRC45~52，以(yi)增加(jia)輪子表面(mian)的(de)耐磨性。支重(zhong)輪的(de)加(jia)工(gong)精度(du)要(yao)求(qiu)比(bi)較(jiao)(jiao)高，一般是(shi)需要(yao)數(shu)控機床進行加(jia)工(gong)才能達到要(yao)求(qiu)。材料以(yi)40Ｍn２較(jiao)(jiao)多，硬度(du)達到HRC42左右(you)。

    支重(zhong)輪輪體材(cai)料(liao)一般50Mn、40Mn2、等材(cai)料(liao)，主要(yao)(yao)工(gong)藝(yi)鑄造(zao)或鍛造(zao)，機(ji)械加(jia)工(gong)，然后(hou)進(jin)行熱處(chu)理(li)，輪子表面淬火(huo)后(hou)的(de)(de)(de)硬度(du)要(yao)(yao)達到(dao)HRC45~52，以(yi)增(zeng)加(jia)輪子表面的(de)(de)(de)耐磨性。支重(zhong)輪軸(zhou)的(de)(de)(de)加(jia)工(gong)精度(du)要(yao)(yao)求(qiu)比較高，一般是需要(yao)(yao)數控(kong)機(ji)床進(jin)行加(jia)工(gong)才能(neng)達到(dao)要(yao)(yao)求(qiu)。材(cai)料(liao)以(yi)40Mn2較多，加(jia)工(gong)后(hou)也要(yao)(yao)進(jin)行淬火(huo)熱處(chu)理(li)，硬度(du)達到(dao)HRC42左(zuo)右。
