錐(zhui)齒輪加工(gong)工(gong)藝流程和難點控制

為(wei)確保(bao)齒(chi)(chi)輪(lun)熱(re)處(chu)理(li)時(shi)，能(neng)夠減(jian)小變形并(bing)獲(huo)得(de)均勻的組(zu)織和較好的機(ji)(ji)械性(xing)能(neng)，在(zai)(zai)機(ji)(ji)加(jia)工(gong)(gong)前，先 對(dui)齒(chi)(chi)坯進(jin)(jin)(jin)行(xing)(xing)高溫正火(huo)(huo)(huo)預(yu)處(chu)理(li)，可以使(shi)組(zu)織得(de)到細化，并(bing)減(jian)小滲(shen)碳(tan)淬(cui)(cui)火(huo)(huo)(huo)時(shi)零(ling)件的變形，同(tong)時(shi)還有(you)利于(yu) 提高切削性(xing)能(neng)。正火(huo)(huo)(huo)后轉機(ji)(ji)加(jia)工(gong)(gong)，先在(zai)(zai)車床上(shang)對(dui)齒(chi)(chi)坯外圓(yuan)、端面進(jin)(jin)(jin)行(xing)(xing)粗、精加(jia)工(gong)(gong)后，在(zai)(zai)臥式(shi)銑(xian)床上(shang)進(jin)(jin)(jin) 行(xing)(xing)銑(xian)齒(chi)(chi)，然后在(zai)(zai)插(cha)床上(shang)插(cha)鍵槽，全部機(ji)(ji)加(jia)工(gong)(gong)完成后，進(jin)(jin)(jin)行(xing)(xing)滲(shen)碳(tan)淬(cui)(cui)火(huo)(huo)(huo)和低(di)溫回火(huo)(huo)(huo)處(chu)理(li)，進(jin)(jin)(jin)行(xing)(xing)后序處(chu) 理(li)。該零(ling)件的工(gong)(gong)藝流程為(wei)：正火(huo)(huo)(huo)→車削→銑(xian)齒(chi)(chi)→插(cha)鍵槽→滲(shen)碳(tan)淬(cui)(cui)火(huo)(huo)(huo)及退火(huo)(huo)(huo)→噴(pen)砂(sha)→防銹(xiu)處(chu)理(li)。工(gong)(gong)藝難點為(wei)銑(xian)齒(chi)(chi)和熱(re)處(chu)理(li)工(gong)(gong)序。
