錐齒輪加(jia)工工藝流程和難點控制

為(wei)確保齒(chi)(chi)輪熱(re)處(chu)理(li)(li)時，能夠減小變(bian)形(xing)并獲得均勻(yun)的組(zu)織和較好的機械性能，在(zai)機加(jia)工(gong)(gong)前，先 對齒(chi)(chi)坯(pi)進(jin)(jin)行高溫(wen)正火(huo)預處(chu)理(li)(li)，可(ke)以(yi)使(shi)組(zu)織得到細化，并減小滲(shen)碳淬(cui)(cui)火(huo)時零(ling)件的變(bian)形(xing)，同時還有利于(yu) 提高切削性能。正火(huo)后(hou)轉機加(jia)工(gong)(gong)，先在(zai)車床(chuang)上對齒(chi)(chi)坯(pi)外圓(yuan)、端面進(jin)(jin)行粗、精加(jia)工(gong)(gong)后(hou)，在(zai)臥(wo)式(shi)銑(xian)床(chuang)上進(jin)(jin) 行銑(xian)齒(chi)(chi)，然后(hou)在(zai)插床(chuang)上插鍵槽，全部機加(jia)工(gong)(gong)完成后(hou)，進(jin)(jin)行滲(shen)碳淬(cui)(cui)火(huo)和低溫(wen)回火(huo)處(chu)理(li)(li)，進(jin)(jin)行后(hou)序(xu)處(chu) 理(li)(li)。該零(ling)件的工(gong)(gong)藝(yi)流(liu)程(cheng)為(wei)：正火(huo)→車削→銑(xian)齒(chi)(chi)→插鍵槽→滲(shen)碳淬(cui)(cui)火(huo)及退火(huo)→噴砂→防銹處(chu)理(li)(li)。工(gong)(gong)藝(yi)難(nan)點為(wei)銑(xian)齒(chi)(chi)和熱(re)處(chu)理(li)(li)工(gong)(gong)序(xu)。
