錐齒輪加工(gong)工(gong)藝(yi)流程(cheng)和難點控制

為(wei)確保(bao)齒(chi)(chi)輪熱處(chu)理(li)(li)時(shi)，能夠減小變形并(bing)獲得均勻的組(zu)織(zhi)和(he)較(jiao)好(hao)的機(ji)械(xie)性(xing)能，在(zai)機(ji)加工(gong)(gong)(gong)前，先(xian)(xian) 對(dui)齒(chi)(chi)坯進(jin)行高(gao)溫(wen)(wen)正火(huo)(huo)預處(chu)理(li)(li)，可以使(shi)組(zu)織(zhi)得到細化，并(bing)減小滲(shen)碳淬火(huo)(huo)時(shi)零件的變形，同時(shi)還有利于 提高(gao)切削(xue)性(xing)能。正火(huo)(huo)后轉機(ji)加工(gong)(gong)(gong)，先(xian)(xian)在(zai)車床(chuang)上對(dui)齒(chi)(chi)坯外圓(yuan)、端面進(jin)行粗、精加工(gong)(gong)(gong)后，在(zai)臥式銑(xian)床(chuang)上進(jin) 行銑(xian)齒(chi)(chi)，然后在(zai)插床(chuang)上插鍵槽(cao)，全部機(ji)加工(gong)(gong)(gong)完成后，進(jin)行滲(shen)碳淬火(huo)(huo)和(he)低溫(wen)(wen)回火(huo)(huo)處(chu)理(li)(li)，進(jin)行后序處(chu) 理(li)(li)。該(gai)零件的工(gong)(gong)(gong)藝流程為(wei)：正火(huo)(huo)→車削(xue)→銑(xian)齒(chi)(chi)→插鍵槽(cao)→滲(shen)碳淬火(huo)(huo)及(ji)退(tui)火(huo)(huo)→噴砂→防銹(xiu)處(chu)理(li)(li)。工(gong)(gong)(gong)藝難點為(wei)銑(xian)齒(chi)(chi)和(he)熱處(chu)理(li)(li)工(gong)(gong)(gong)序。
