錐齒輪加(jia)工(gong)工(gong)藝流程和難點控制

為確保齒(chi)(chi)輪熱處(chu)理(li)(li)時(shi)，能夠減小變(bian)形并(bing)獲得均勻的(de)組織和(he)較好的(de)機(ji)(ji)械性能，在(zai)機(ji)(ji)加(jia)工(gong)(gong)(gong)前，先 對齒(chi)(chi)坯(pi)進(jin)(jin)行(xing)高(gao)溫正(zheng)(zheng)火(huo)(huo)(huo)預處(chu)理(li)(li)，可(ke)以使組織得到細化，并(bing)減小滲碳(tan)(tan)淬(cui)火(huo)(huo)(huo)時(shi)零件(jian)的(de)變(bian)形，同(tong)時(shi)還有利(li)于(yu) 提高(gao)切(qie)削(xue)性能。正(zheng)(zheng)火(huo)(huo)(huo)后轉機(ji)(ji)加(jia)工(gong)(gong)(gong)，先在(zai)車床(chuang)(chuang)上(shang)(shang)對齒(chi)(chi)坯(pi)外(wai)圓、端面進(jin)(jin)行(xing)粗、精(jing)加(jia)工(gong)(gong)(gong)后，在(zai)臥式銑床(chuang)(chuang)上(shang)(shang)進(jin)(jin) 行(xing)銑齒(chi)(chi)，然后在(zai)插(cha)床(chuang)(chuang)上(shang)(shang)插(cha)鍵(jian)槽，全部機(ji)(ji)加(jia)工(gong)(gong)(gong)完成(cheng)后，進(jin)(jin)行(xing)滲碳(tan)(tan)淬(cui)火(huo)(huo)(huo)和(he)低(di)溫回火(huo)(huo)(huo)處(chu)理(li)(li)，進(jin)(jin)行(xing)后序處(chu) 理(li)(li)。該零件(jian)的(de)工(gong)(gong)(gong)藝(yi)流(liu)程為：正(zheng)(zheng)火(huo)(huo)(huo)→車削(xue)→銑齒(chi)(chi)→插(cha)鍵(jian)槽→滲碳(tan)(tan)淬(cui)火(huo)(huo)(huo)及退(tui)火(huo)(huo)(huo)→噴砂→防銹處(chu)理(li)(li)。工(gong)(gong)(gong)藝(yi)難點為銑齒(chi)(chi)和(he)熱處(chu)理(li)(li)工(gong)(gong)(gong)序。
