錐齒輪加工工藝流程(cheng)和難點控(kong)制

為(wei)(wei)確保齒(chi)(chi)輪(lun)熱處(chu)(chu)理(li)(li)時(shi)，能夠減小變形(xing)并獲得均勻的組織和較好的機(ji)械性(xing)能，在(zai)機(ji)加(jia)工(gong)(gong)前，先(xian) 對齒(chi)(chi)坯進行(xing)高溫(wen)正火(huo)預處(chu)(chu)理(li)(li)，可以使組織得到細化，并減小滲(shen)(shen)碳(tan)(tan)淬火(huo)時(shi)零件的變形(xing)，同時(shi)還有利(li)于 提高切削性(xing)能。正火(huo)后(hou)(hou)轉機(ji)加(jia)工(gong)(gong)，先(xian)在(zai)車床(chuang)上(shang)對齒(chi)(chi)坯外圓、端面(mian)進行(xing)粗、精加(jia)工(gong)(gong)后(hou)(hou)，在(zai)臥(wo)式(shi)銑(xian)(xian)床(chuang)上(shang)進 行(xing)銑(xian)(xian)齒(chi)(chi)，然后(hou)(hou)在(zai)插床(chuang)上(shang)插鍵(jian)槽，全部(bu)機(ji)加(jia)工(gong)(gong)完成后(hou)(hou)，進行(xing)滲(shen)(shen)碳(tan)(tan)淬火(huo)和低溫(wen)回(hui)火(huo)處(chu)(chu)理(li)(li)，進行(xing)后(hou)(hou)序處(chu)(chu) 理(li)(li)。該零件的工(gong)(gong)藝流程為(wei)(wei)：正火(huo)→車削→銑(xian)(xian)齒(chi)(chi)→插鍵(jian)槽→滲(shen)(shen)碳(tan)(tan)淬火(huo)及退火(huo)→噴砂→防銹(xiu)處(chu)(chu)理(li)(li)。工(gong)(gong)藝難點為(wei)(wei)銑(xian)(xian)齒(chi)(chi)和熱處(chu)(chu)理(li)(li)工(gong)(gong)序。
