錐齒輪加工工藝流程和難(nan)點控制

為確(que)保齒(chi)輪熱(re)處(chu)理時(shi)(shi)，能(neng)夠(gou)減小變形(xing)并獲(huo)得均勻的(de)(de)組織和(he)較好的(de)(de)機(ji)械(xie)性(xing)能(neng)，在(zai)機(ji)加(jia)工(gong)(gong)前(qian)，先(xian) 對齒(chi)坯進行高溫正火預處(chu)理，可以使組織得到細化，并減小滲(shen)(shen)碳(tan)淬(cui)火時(shi)(shi)零(ling)(ling)件(jian)的(de)(de)變形(xing)，同時(shi)(shi)還有利于 提高切削性(xing)能(neng)。正火后轉機(ji)加(jia)工(gong)(gong)，先(xian)在(zai)車(che)床上對齒(chi)坯外圓(yuan)、端面進行粗、精(jing)加(jia)工(gong)(gong)后，在(zai)臥(wo)式(shi)銑(xian)床上進 行銑(xian)齒(chi)，然后在(zai)插床上插鍵槽，全部機(ji)加(jia)工(gong)(gong)完(wan)成后，進行滲(shen)(shen)碳(tan)淬(cui)火和(he)低溫回火處(chu)理，進行后序處(chu) 理。該零(ling)(ling)件(jian)的(de)(de)工(gong)(gong)藝流程為：正火→車(che)削→銑(xian)齒(chi)→插鍵槽→滲(shen)(shen)碳(tan)淬(cui)火及(ji)退火→噴砂→防銹(xiu)處(chu)理。工(gong)(gong)藝難點為銑(xian)齒(chi)和(he)熱(re)處(chu)理工(gong)(gong)序。
