輪(lun)體、支(zhi)(zhi)重(zhong)輪(lun)軸(zhou)、軸(zhou)套、密封(feng)圈、端蓋等相(xiang)關部件構(gou)成。支(zhi)(zhi)重(zhong)輪(lun)可分為單(dan)邊支(zhi)(zhi)重(zhong)輪(lun)與(yu)雙邊支(zhi)(zhi)重(zhong)輪(lun)；挖掘(jue)機(ji)(ji)用(yong)支(zhi)(zhi)重(zhong)輪(lun)與(yu)推土機(ji)(ji)用(yong)支(zhi)(zhi)重(zhong)輪(lun)，挖掘(jue)機(ji)(ji)用(yong)支(zhi)(zhi)重(zhong)輪(lun)一般是黑色油漆，推土機(ji)(ji)支(zhi)(zhi)重(zhong)輪(lun)一般是黃色油漆

支(zhi)重輪(lun)輪(lun)體材料一般(ban)50Mn、40Mn2、等材料，主要工藝鑄造(zao)或鍛造(zao)，機(ji)(ji)械加工，然后進(jin)行熱處理，輪(lun)子(zi)表(biao)面(mian)淬(cui)火后的硬度要達(da)(da)到HRC45~52，以(yi)增加輪(lun)子(zi)表(biao)面(mian)的耐磨性。支(zhi)重輪(lun)軸的加工精度要求比(bi)較(jiao)(jiao)高，一般(ban)是需要數控(kong)機(ji)(ji)床(chuang)進(jin)行加工才能(neng)達(da)(da)到要求。材料以(yi)40Mn2較(jiao)(jiao)多，加工后也要進(jin)行淬(cui)火熱處理，硬度達(da)(da)到HRC42左右

湖北中特工程機械有限公司，成立于2009年，位于湖北咸(xian)寧市(shi)咸(xian)安(an)經濟開發區，注冊資金1000萬元(yuan)，專業技術人員23名(ming)，員工220名(ming)，廠區占地70畝。

履帶編輯分類：有整體式和組合式兩種。整體式履帶是履帶板上帶嚙合齒，趨勢與驅動輪嚙合，履帶板本身成為支重輪等輪子的滾動軌道。特點：制造方便，但是磨損快。挖掘機多用組合式特點是，節距小，繞轉性好，挖掘機的行走速度快。使用壽命長。所用材為的履帶板的材料多是重量輕，強度高，結構簡單和價格便宜的軋制板。有單筋，雙筋，三筋等數種。
