錐齒輪加(jia)工(gong)工(gong)藝流程(cheng)和難點控制

為確保齒(chi)(chi)輪熱處(chu)(chu)理(li)時(shi)，能夠減(jian)小變形并(bing)獲得均勻的(de)組織和較(jiao)好的(de)機(ji)械性能，在機(ji)加(jia)(jia)(jia)工(gong)(gong)前，先(xian) 對齒(chi)(chi)坯(pi)進(jin)(jin)(jin)行高溫正火(huo)預處(chu)(chu)理(li)，可以使組織得到細化，并(bing)減(jian)小滲(shen)碳淬(cui)(cui)火(huo)時(shi)零件的(de)變形，同時(shi)還(huan)有(you)利于(yu) 提高切削(xue)性能。正火(huo)后(hou)轉(zhuan)機(ji)加(jia)(jia)(jia)工(gong)(gong)，先(xian)在車(che)床上對齒(chi)(chi)坯(pi)外圓、端(duan)面進(jin)(jin)(jin)行粗、精加(jia)(jia)(jia)工(gong)(gong)后(hou)，在臥式(shi)銑床上進(jin)(jin)(jin) 行銑齒(chi)(chi)，然后(hou)在插(cha)(cha)床上插(cha)(cha)鍵(jian)(jian)槽，全部(bu)機(ji)加(jia)(jia)(jia)工(gong)(gong)完成后(hou)，進(jin)(jin)(jin)行滲(shen)碳淬(cui)(cui)火(huo)和低溫回火(huo)處(chu)(chu)理(li)，進(jin)(jin)(jin)行后(hou)序處(chu)(chu) 理(li)。該零件的(de)工(gong)(gong)藝流程為：正火(huo)→車(che)削(xue)→銑齒(chi)(chi)→插(cha)(cha)鍵(jian)(jian)槽→滲(shen)碳淬(cui)(cui)火(huo)及(ji)退火(huo)→噴砂→防銹處(chu)(chu)理(li)。工(gong)(gong)藝難點為銑齒(chi)(chi)和熱處(chu)(chu)理(li)工(gong)(gong)序。
