錐(zhui)齒輪加工工藝流(liu)程和難點控制

為(wei)(wei)確(que)保齒輪熱(re)處(chu)(chu)理(li)時(shi)，能(neng)夠(gou)減(jian)小變形(xing)并(bing)獲(huo)得均勻(yun)的(de)(de)組織和較好的(de)(de)機(ji)械性能(neng)，在(zai)機(ji)加(jia)工(gong)(gong)(gong)(gong)前，先 對(dui)齒坯進行(xing)高溫正火(huo)(huo)預處(chu)(chu)理(li)，可以使組織得到細化，并(bing)減(jian)小滲(shen)碳(tan)淬(cui)火(huo)(huo)時(shi)零件的(de)(de)變形(xing)，同時(shi)還有利于 提(ti)高切(qie)削性能(neng)。正火(huo)(huo)后(hou)轉機(ji)加(jia)工(gong)(gong)(gong)(gong)，先在(zai)車床(chuang)上(shang)對(dui)齒坯外圓、端面(mian)進行(xing)粗、精(jing)加(jia)工(gong)(gong)(gong)(gong)后(hou)，在(zai)臥式(shi)銑(xian)(xian)床(chuang)上(shang)進 行(xing)銑(xian)(xian)齒，然(ran)后(hou)在(zai)插床(chuang)上(shang)插鍵(jian)槽(cao)，全部(bu)機(ji)加(jia)工(gong)(gong)(gong)(gong)完(wan)成后(hou)，進行(xing)滲(shen)碳(tan)淬(cui)火(huo)(huo)和低溫回火(huo)(huo)處(chu)(chu)理(li)，進行(xing)后(hou)序(xu)(xu)處(chu)(chu) 理(li)。該零件的(de)(de)工(gong)(gong)(gong)(gong)藝流程為(wei)(wei)：正火(huo)(huo)→車削→銑(xian)(xian)齒→插鍵(jian)槽(cao)→滲(shen)碳(tan)淬(cui)火(huo)(huo)及退火(huo)(huo)→噴砂(sha)→防銹處(chu)(chu)理(li)。工(gong)(gong)(gong)(gong)藝難點為(wei)(wei)銑(xian)(xian)齒和熱(re)處(chu)(chu)理(li)工(gong)(gong)(gong)(gong)序(xu)(xu)。
