錐齒輪(lun)加工(gong)工(gong)藝流程和難點(dian)控(kong)制

為確(que)保齒(chi)輪熱(re)處(chu)(chu)理(li)(li)時(shi)(shi)，能夠減小(xiao)變(bian)形并獲得均勻(yun)的(de)組織和(he)較好的(de)機械性(xing)能，在機加(jia)工(gong)(gong)(gong)(gong)前，先 對齒(chi)坯(pi)進(jin)行(xing)(xing)高(gao)溫正(zheng)火預處(chu)(chu)理(li)(li)，可以使組織得到(dao)細化，并減小(xiao)滲(shen)碳淬(cui)(cui)火時(shi)(shi)零件的(de)變(bian)形，同時(shi)(shi)還有利于 提高(gao)切削性(xing)能。正(zheng)火后(hou)轉機加(jia)工(gong)(gong)(gong)(gong)，先在車床(chuang)上對齒(chi)坯(pi)外圓、端面進(jin)行(xing)(xing)粗、精(jing)加(jia)工(gong)(gong)(gong)(gong)后(hou)，在臥式銑(xian)床(chuang)上進(jin) 行(xing)(xing)銑(xian)齒(chi)，然后(hou)在插床(chuang)上插鍵(jian)槽，全部(bu)機加(jia)工(gong)(gong)(gong)(gong)完成(cheng)后(hou)，進(jin)行(xing)(xing)滲(shen)碳淬(cui)(cui)火和(he)低溫回火處(chu)(chu)理(li)(li)，進(jin)行(xing)(xing)后(hou)序(xu)(xu)處(chu)(chu) 理(li)(li)。該零件的(de)工(gong)(gong)(gong)(gong)藝流程(cheng)為：正(zheng)火→車削→銑(xian)齒(chi)→插鍵(jian)槽→滲(shen)碳淬(cui)(cui)火及退(tui)火→噴砂(sha)→防銹處(chu)(chu)理(li)(li)。工(gong)(gong)(gong)(gong)藝難點為銑(xian)齒(chi)和(he)熱(re)處(chu)(chu)理(li)(li)工(gong)(gong)(gong)(gong)序(xu)(xu)。
