錐齒輪加工(gong)工(gong)藝(yi)流程和難點控制

為確(que)保齒(chi)輪熱(re)(re)處(chu)理(li)(li)時(shi)(shi)，能(neng)夠減小變形(xing)并獲得均勻的(de)組(zu)(zu)織(zhi)和(he)較(jiao)好的(de)機(ji)械性能(neng)，在(zai)機(ji)加工(gong)(gong)(gong)前，先(xian) 對齒(chi)坯(pi)進行(xing)高(gao)溫正火(huo)預處(chu)理(li)(li)，可以使組(zu)(zu)織(zhi)得到細化，并減小滲碳(tan)淬火(huo)時(shi)(shi)零件的(de)變形(xing)，同時(shi)(shi)還有利于 提高(gao)切(qie)削(xue)性能(neng)。正火(huo)后轉機(ji)加工(gong)(gong)(gong)，先(xian)在(zai)車床(chuang)上對齒(chi)坯(pi)外圓、端面進行(xing)粗、精加工(gong)(gong)(gong)后，在(zai)臥式(shi)銑床(chuang)上進 行(xing)銑齒(chi)，然后在(zai)插床(chuang)上插鍵(jian)槽，全部機(ji)加工(gong)(gong)(gong)完(wan)成(cheng)后，進行(xing)滲碳(tan)淬火(huo)和(he)低溫回火(huo)處(chu)理(li)(li)，進行(xing)后序處(chu) 理(li)(li)。該零件的(de)工(gong)(gong)(gong)藝流程(cheng)為：正火(huo)→車削(xue)→銑齒(chi)→插鍵(jian)槽→滲碳(tan)淬火(huo)及(ji)退火(huo)→噴砂→防銹處(chu)理(li)(li)。工(gong)(gong)(gong)藝難點為銑齒(chi)和(he)熱(re)(re)處(chu)理(li)(li)工(gong)(gong)(gong)序。
