錐(zhui)齒輪加工(gong)工(gong)藝流程和難點控制
為確保齒(chi)輪(lun)熱(re)處理(li)(li)時(shi),能(neng)夠減(jian)(jian)小變(bian)形并(bing)獲得均勻的(de)組織(zhi)和(he)較(jiao)好的(de)機械(xie)性(xing)能(neng),在(zai)機加(jia)工(gong)前,先 對齒(chi)坯進(jin)(jin)行(xing)高溫正火預處理(li)(li),可以(yi)使(shi)組織(zhi)得到細化,并(bing)減(jian)(jian)小滲(shen)碳(tan)淬(cui)(cui)火時(shi)零(ling)件(jian)的(de)變(bian)形,同(tong)時(shi)還有利于 提高切削性(xing)能(neng)。正火后(hou)轉機加(jia)工(gong),先在(zai)車床上對齒(chi)坯外圓、端面進(jin)(jin)行(xing)粗(cu)、精加(jia)工(gong)后(hou),在(zai)臥式(shi)銑(xian)床上進(jin)(jin) 行(xing)銑(xian)齒(chi),然后(hou)在(zai)插(cha)床上插(cha)鍵槽,全部機加(jia)工(gong)完(wan)成后(hou),進(jin)(jin)行(xing)滲(shen)碳(tan)淬(cui)(cui)火和(he)低溫回火處理(li)(li),進(jin)(jin)行(xing)后(hou)序處 理(li)(li)。該零(ling)件(jian)的(de)工(gong)藝(yi)流程為:正火→車削→銑(xian)齒(chi)→插(cha)鍵槽→滲(shen)碳(tan)淬(cui)(cui)火及(ji)退火→噴砂→防(fang)銹(xiu)處理(li)(li)。工(gong)藝(yi)難點為銑(xian)齒(chi)和(he)熱(re)處理(li)(li)工(gong)序。
