錐齒輪加工工藝(yi)流(liu)程和難點控制

為確(que)保齒(chi)輪熱(re)處(chu)(chu)(chu)理(li)(li)時(shi)(shi)，能夠減小(xiao)變(bian)形并獲(huo)得均勻的(de)組織(zhi)和較好的(de)機械(xie)性(xing)能，在(zai)機加(jia)工(gong)(gong)(gong)(gong)前，先 對(dui)齒(chi)坯(pi)進(jin)行(xing)(xing)(xing)高(gao)溫正火(huo)(huo)預(yu)處(chu)(chu)(chu)理(li)(li)，可以使組織(zhi)得到細化，并減小(xiao)滲碳(tan)淬(cui)(cui)火(huo)(huo)時(shi)(shi)零(ling)件的(de)變(bian)形，同時(shi)(shi)還有利于 提(ti)高(gao)切削性(xing)能。正火(huo)(huo)后(hou)轉機加(jia)工(gong)(gong)(gong)(gong)，先在(zai)車床上對(dui)齒(chi)坯(pi)外(wai)圓、端(duan)面進(jin)行(xing)(xing)(xing)粗、精加(jia)工(gong)(gong)(gong)(gong)后(hou)，在(zai)臥式(shi)銑床上進(jin) 行(xing)(xing)(xing)銑齒(chi)，然后(hou)在(zai)插(cha)床上插(cha)鍵(jian)槽(cao)，全部機加(jia)工(gong)(gong)(gong)(gong)完成后(hou)，進(jin)行(xing)(xing)(xing)滲碳(tan)淬(cui)(cui)火(huo)(huo)和低溫回(hui)火(huo)(huo)處(chu)(chu)(chu)理(li)(li)，進(jin)行(xing)(xing)(xing)后(hou)序處(chu)(chu)(chu) 理(li)(li)。該(gai)零(ling)件的(de)工(gong)(gong)(gong)(gong)藝(yi)流(liu)程為：正火(huo)(huo)→車削→銑齒(chi)→插(cha)鍵(jian)槽(cao)→滲碳(tan)淬(cui)(cui)火(huo)(huo)及退火(huo)(huo)→噴(pen)砂→防(fang)銹處(chu)(chu)(chu)理(li)(li)。工(gong)(gong)(gong)(gong)藝(yi)難點為銑齒(chi)和熱(re)處(chu)(chu)(chu)理(li)(li)工(gong)(gong)(gong)(gong)序。
