錐齒(chi)輪(lun)加工(gong)工(gong)藝流程和難點控制

為(wei)確(que)保齒(chi)(chi)輪熱處(chu)(chu)理(li)(li)時(shi)，能夠(gou)減小變(bian)形并獲得均勻的(de)組(zu)織和(he)較好的(de)機械性(xing)能，在機加(jia)工(gong)(gong)前，先 對(dui)齒(chi)(chi)坯(pi)進(jin)(jin)(jin)行高(gao)溫(wen)正火(huo)(huo)預處(chu)(chu)理(li)(li)，可以使組(zu)織得到細化，并減小滲(shen)(shen)碳(tan)(tan)淬(cui)火(huo)(huo)時(shi)零(ling)件(jian)的(de)變(bian)形，同時(shi)還(huan)有利于 提高(gao)切削性(xing)能。正火(huo)(huo)后(hou)轉機加(jia)工(gong)(gong)，先在車床(chuang)上(shang)對(dui)齒(chi)(chi)坯(pi)外圓、端面(mian)進(jin)(jin)(jin)行粗、精加(jia)工(gong)(gong)后(hou)，在臥式銑(xian)(xian)(xian)床(chuang)上(shang)進(jin)(jin)(jin) 行銑(xian)(xian)(xian)齒(chi)(chi)，然后(hou)在插床(chuang)上(shang)插鍵(jian)槽，全部機加(jia)工(gong)(gong)完成后(hou)，進(jin)(jin)(jin)行滲(shen)(shen)碳(tan)(tan)淬(cui)火(huo)(huo)和(he)低溫(wen)回(hui)火(huo)(huo)處(chu)(chu)理(li)(li)，進(jin)(jin)(jin)行后(hou)序(xu)處(chu)(chu) 理(li)(li)。該零(ling)件(jian)的(de)工(gong)(gong)藝(yi)流程(cheng)為(wei)：正火(huo)(huo)→車削→銑(xian)(xian)(xian)齒(chi)(chi)→插鍵(jian)槽→滲(shen)(shen)碳(tan)(tan)淬(cui)火(huo)(huo)及退火(huo)(huo)→噴砂→防銹處(chu)(chu)理(li)(li)。工(gong)(gong)藝(yi)難點為(wei)銑(xian)(xian)(xian)齒(chi)(chi)和(he)熱處(chu)(chu)理(li)(li)工(gong)(gong)序(xu)。
