錐齒輪加工工藝流程和難點控制

為確保齒輪熱處(chu)(chu)理(li)時(shi)，能夠減小變形并獲得均勻的(de)組織和(he)較(jiao)好的(de)機(ji)械性(xing)能，在機(ji)加(jia)工(gong)(gong)前，先 對(dui)(dui)齒坯進(jin)(jin)行(xing)高(gao)溫(wen)(wen)正(zheng)火(huo)預處(chu)(chu)理(li)，可以使組織得到細化，并減小滲碳淬(cui)火(huo)時(shi)零件(jian)(jian)的(de)變形，同時(shi)還(huan)有(you)利(li)于 提(ti)高(gao)切削性(xing)能。正(zheng)火(huo)后轉機(ji)加(jia)工(gong)(gong)，先在車床上對(dui)(dui)齒坯外圓、端(duan)面進(jin)(jin)行(xing)粗(cu)、精加(jia)工(gong)(gong)后，在臥式銑(xian)床上進(jin)(jin) 行(xing)銑(xian)齒，然(ran)后在插床上插鍵槽，全部機(ji)加(jia)工(gong)(gong)完成(cheng)后，進(jin)(jin)行(xing)滲碳淬(cui)火(huo)和(he)低溫(wen)(wen)回火(huo)處(chu)(chu)理(li)，進(jin)(jin)行(xing)后序處(chu)(chu) 理(li)。該零件(jian)(jian)的(de)工(gong)(gong)藝流程為：正(zheng)火(huo)→車削→銑(xian)齒→插鍵槽→滲碳淬(cui)火(huo)及退火(huo)→噴砂→防銹處(chu)(chu)理(li)。工(gong)(gong)藝難點為銑(xian)齒和(he)熱處(chu)(chu)理(li)工(gong)(gong)序。
