錐齒輪(lun)加工工藝流程和難點控制

為(wei)確(que)保齒(chi)輪熱處(chu)理時(shi)，能(neng)夠(gou)減(jian)小變形并獲得(de)(de)均勻的(de)組織和較好(hao)的(de)機械性能(neng)，在機加(jia)工(gong)(gong)前，先 對齒(chi)坯進(jin)行(xing)高溫(wen)正(zheng)火預處(chu)理，可以使組織得(de)(de)到細(xi)化，并減(jian)小滲(shen)碳(tan)淬火時(shi)零件的(de)變形，同時(shi)還(huan)有利于 提高切削性能(neng)。正(zheng)火后(hou)轉機加(jia)工(gong)(gong)，先在車床(chuang)(chuang)上對齒(chi)坯外圓、端面進(jin)行(xing)粗、精加(jia)工(gong)(gong)后(hou)，在臥式銑(xian)床(chuang)(chuang)上進(jin) 行(xing)銑(xian)齒(chi)，然后(hou)在插(cha)(cha)床(chuang)(chuang)上插(cha)(cha)鍵槽(cao)，全部機加(jia)工(gong)(gong)完成后(hou)，進(jin)行(xing)滲(shen)碳(tan)淬火和低溫(wen)回火處(chu)理，進(jin)行(xing)后(hou)序處(chu) 理。該零件的(de)工(gong)(gong)藝流程為(wei)：正(zheng)火→車削→銑(xian)齒(chi)→插(cha)(cha)鍵槽(cao)→滲(shen)碳(tan)淬火及退火→噴砂→防(fang)銹處(chu)理。工(gong)(gong)藝難點為(wei)銑(xian)齒(chi)和熱處(chu)理工(gong)(gong)序。
