錐齒輪加工(gong)工(gong)藝(yi)流程和難點控制(zhi)

為(wei)確保齒(chi)(chi)(chi)輪熱處(chu)(chu)理(li)(li)時(shi)(shi)，能(neng)夠減(jian)小變形并(bing)獲得均(jun)勻(yun)的組織和較好的機械(xie)性能(neng)，在(zai)機加工(gong)前，先 對齒(chi)(chi)(chi)坯(pi)進(jin)(jin)(jin)(jin)(jin)行高溫正火(huo)預處(chu)(chu)理(li)(li)，可以使組織得到(dao)細化，并(bing)減(jian)小滲碳(tan)(tan)淬(cui)火(huo)時(shi)(shi)零件的變形，同時(shi)(shi)還有(you)利于 提高切削性能(neng)。正火(huo)后(hou)轉機加工(gong)，先在(zai)車床上(shang)對齒(chi)(chi)(chi)坯(pi)外(wai)圓、端面進(jin)(jin)(jin)(jin)(jin)行粗、精加工(gong)后(hou)，在(zai)臥(wo)式銑(xian)(xian)床上(shang)進(jin)(jin)(jin)(jin)(jin) 行銑(xian)(xian)齒(chi)(chi)(chi)，然后(hou)在(zai)插(cha)床上(shang)插(cha)鍵(jian)槽，全部機加工(gong)完成(cheng)后(hou)，進(jin)(jin)(jin)(jin)(jin)行滲碳(tan)(tan)淬(cui)火(huo)和低(di)溫回(hui)火(huo)處(chu)(chu)理(li)(li)，進(jin)(jin)(jin)(jin)(jin)行后(hou)序處(chu)(chu) 理(li)(li)。該零件的工(gong)藝流(liu)程(cheng)為(wei)：正火(huo)→車削→銑(xian)(xian)齒(chi)(chi)(chi)→插(cha)鍵(jian)槽→滲碳(tan)(tan)淬(cui)火(huo)及退火(huo)→噴砂→防(fang)銹處(chu)(chu)理(li)(li)。工(gong)藝難(nan)點(dian)為(wei)銑(xian)(xian)齒(chi)(chi)(chi)和熱處(chu)(chu)理(li)(li)工(gong)序。
