錐齒輪加工工藝流程和難點控制(zhi)

為確保齒(chi)輪熱(re)處(chu)(chu)(chu)理(li)時(shi)，能(neng)夠(gou)減(jian)(jian)小變(bian)形并(bing)(bing)獲得均(jun)勻的(de)(de)組織和較好的(de)(de)機械性能(neng)，在(zai)機加(jia)工(gong)(gong)(gong)前，先 對(dui)齒(chi)坯(pi)進(jin)行(xing)(xing)(xing)高溫(wen)正火(huo)預處(chu)(chu)(chu)理(li)，可以使組織得到細化，并(bing)(bing)減(jian)(jian)小滲(shen)碳(tan)淬(cui)火(huo)時(shi)零件(jian)的(de)(de)變(bian)形，同時(shi)還有利于 提(ti)高切削性能(neng)。正火(huo)后(hou)(hou)轉機加(jia)工(gong)(gong)(gong)，先在(zai)車(che)(che)床(chuang)(chuang)上(shang)對(dui)齒(chi)坯(pi)外(wai)圓、端面進(jin)行(xing)(xing)(xing)粗(cu)、精加(jia)工(gong)(gong)(gong)后(hou)(hou)，在(zai)臥式(shi)銑(xian)床(chuang)(chuang)上(shang)進(jin) 行(xing)(xing)(xing)銑(xian)齒(chi)，然后(hou)(hou)在(zai)插(cha)床(chuang)(chuang)上(shang)插(cha)鍵(jian)(jian)槽，全部(bu)機加(jia)工(gong)(gong)(gong)完成后(hou)(hou)，進(jin)行(xing)(xing)(xing)滲(shen)碳(tan)淬(cui)火(huo)和低(di)溫(wen)回火(huo)處(chu)(chu)(chu)理(li)，進(jin)行(xing)(xing)(xing)后(hou)(hou)序(xu)處(chu)(chu)(chu) 理(li)。該零件(jian)的(de)(de)工(gong)(gong)(gong)藝流程為：正火(huo)→車(che)(che)削→銑(xian)齒(chi)→插(cha)鍵(jian)(jian)槽→滲(shen)碳(tan)淬(cui)火(huo)及退(tui)火(huo)→噴砂(sha)→防銹處(chu)(chu)(chu)理(li)。工(gong)(gong)(gong)藝難(nan)點為銑(xian)齒(chi)和熱(re)處(chu)(chu)(chu)理(li)工(gong)(gong)(gong)序(xu)。
