錐(zhui)齒輪加工(gong)工(gong)藝流(liu)程和難點控制

為(wei)(wei)確保齒(chi)(chi)輪熱處(chu)(chu)(chu)理(li)時(shi)，能(neng)夠減(jian)小(xiao)變(bian)(bian)形并獲得均勻的(de)組(zu)織(zhi)和(he)(he)較好的(de)機(ji)械(xie)性能(neng)，在機(ji)加(jia)(jia)工(gong)前，先 對齒(chi)(chi)坯進(jin)行(xing)高溫正火(huo)預處(chu)(chu)(chu)理(li)，可以使(shi)組(zu)織(zhi)得到細化，并減(jian)小(xiao)滲(shen)碳(tan)淬(cui)火(huo)時(shi)零件(jian)的(de)變(bian)(bian)形，同時(shi)還有利于 提高切(qie)削性能(neng)。正火(huo)后(hou)轉(zhuan)機(ji)加(jia)(jia)工(gong)，先在車(che)床(chuang)上(shang)對齒(chi)(chi)坯外(wai)圓、端面進(jin)行(xing)粗、精(jing)加(jia)(jia)工(gong)后(hou)，在臥式銑(xian)(xian)床(chuang)上(shang)進(jin) 行(xing)銑(xian)(xian)齒(chi)(chi)，然后(hou)在插床(chuang)上(shang)插鍵槽(cao)，全部機(ji)加(jia)(jia)工(gong)完(wan)成后(hou)，進(jin)行(xing)滲(shen)碳(tan)淬(cui)火(huo)和(he)(he)低溫回火(huo)處(chu)(chu)(chu)理(li)，進(jin)行(xing)后(hou)序處(chu)(chu)(chu) 理(li)。該零件(jian)的(de)工(gong)藝(yi)流程為(wei)(wei)：正火(huo)→車(che)削→銑(xian)(xian)齒(chi)(chi)→插鍵槽(cao)→滲(shen)碳(tan)淬(cui)火(huo)及退火(huo)→噴砂(sha)→防銹(xiu)處(chu)(chu)(chu)理(li)。工(gong)藝(yi)難點(dian)為(wei)(wei)銑(xian)(xian)齒(chi)(chi)和(he)(he)熱處(chu)(chu)(chu)理(li)工(gong)序。
