錐(zhui)齒輪加工(gong)工(gong)藝流程和難點控(kong)制

為確保齒(chi)(chi)(chi)輪熱處理(li)(li)(li)(li)時，能夠減小變(bian)形并獲(huo)得(de)均勻的(de)(de)組織和(he)較好的(de)(de)機械性(xing)能，在機加(jia)工(gong)(gong)(gong)前，先(xian) 對齒(chi)(chi)(chi)坯(pi)進(jin)行高(gao)溫正(zheng)火(huo)(huo)預(yu)處理(li)(li)(li)(li)，可以使組織得(de)到細(xi)化，并減小滲(shen)碳(tan)淬(cui)火(huo)(huo)時零件(jian)的(de)(de)變(bian)形，同時還(huan)有利于 提高(gao)切削性(xing)能。正(zheng)火(huo)(huo)后(hou)轉機加(jia)工(gong)(gong)(gong)，先(xian)在車(che)床上對齒(chi)(chi)(chi)坯(pi)外圓(yuan)、端面進(jin)行粗(cu)、精加(jia)工(gong)(gong)(gong)后(hou)，在臥(wo)式銑床上進(jin) 行銑齒(chi)(chi)(chi)，然后(hou)在插床上插鍵(jian)槽(cao)，全部機加(jia)工(gong)(gong)(gong)完成后(hou)，進(jin)行滲(shen)碳(tan)淬(cui)火(huo)(huo)和(he)低溫回(hui)火(huo)(huo)處理(li)(li)(li)(li)，進(jin)行后(hou)序(xu)處 理(li)(li)(li)(li)。該零件(jian)的(de)(de)工(gong)(gong)(gong)藝流(liu)程為：正(zheng)火(huo)(huo)→車(che)削→銑齒(chi)(chi)(chi)→插鍵(jian)槽(cao)→滲(shen)碳(tan)淬(cui)火(huo)(huo)及退(tui)火(huo)(huo)→噴砂→防銹處理(li)(li)(li)(li)。工(gong)(gong)(gong)藝難(nan)點(dian)為銑齒(chi)(chi)(chi)和(he)熱處理(li)(li)(li)(li)工(gong)(gong)(gong)序(xu)。
