錐(zhui)齒輪加(jia)工(gong)(gong)工(gong)(gong)藝流程和難點控制

為(wei)確保齒(chi)(chi)輪(lun)熱處(chu)理(li)時(shi)，能夠減小(xiao)變形并獲得均勻的(de)(de)組織(zhi)(zhi)和較好的(de)(de)機(ji)械(xie)性(xing)能，在機(ji)加(jia)工(gong)(gong)(gong)前，先(xian) 對齒(chi)(chi)坯進行(xing)高(gao)溫正火(huo)預(yu)處(chu)理(li)，可以使組織(zhi)(zhi)得到細化(hua)，并減小(xiao)滲(shen)碳(tan)淬(cui)(cui)火(huo)時(shi)零(ling)件的(de)(de)變形，同時(shi)還有利于 提(ti)高(gao)切削(xue)性(xing)能。正火(huo)后(hou)(hou)轉(zhuan)機(ji)加(jia)工(gong)(gong)(gong)，先(xian)在車(che)床上對齒(chi)(chi)坯外(wai)圓、端面進行(xing)粗、精加(jia)工(gong)(gong)(gong)后(hou)(hou)，在臥式銑(xian)床上進 行(xing)銑(xian)齒(chi)(chi)，然后(hou)(hou)在插(cha)床上插(cha)鍵槽，全部機(ji)加(jia)工(gong)(gong)(gong)完(wan)成后(hou)(hou)，進行(xing)滲(shen)碳(tan)淬(cui)(cui)火(huo)和低溫回火(huo)處(chu)理(li)，進行(xing)后(hou)(hou)序(xu)處(chu) 理(li)。該零(ling)件的(de)(de)工(gong)(gong)(gong)藝(yi)(yi)流程(cheng)為(wei)：正火(huo)→車(che)削(xue)→銑(xian)齒(chi)(chi)→插(cha)鍵槽→滲(shen)碳(tan)淬(cui)(cui)火(huo)及退火(huo)→噴砂→防(fang)銹處(chu)理(li)。工(gong)(gong)(gong)藝(yi)(yi)難點為(wei)銑(xian)齒(chi)(chi)和熱處(chu)理(li)工(gong)(gong)(gong)序(xu)。
