錐齒輪加工(gong)(gong)工(gong)(gong)藝(yi)流程和難點(dian)控制

為(wei)(wei)確保齒(chi)(chi)輪熱處(chu)(chu)理(li)(li)時，能(neng)夠減小(xiao)變(bian)形并(bing)獲得均勻的組(zu)(zu)織和(he)(he)較好(hao)的機(ji)械(xie)性(xing)(xing)能(neng)，在機(ji)加(jia)工(gong)前，先 對(dui)齒(chi)(chi)坯進(jin)(jin)行(xing)高(gao)溫正(zheng)火(huo)預處(chu)(chu)理(li)(li)，可(ke)以使組(zu)(zu)織得到細化(hua)，并(bing)減小(xiao)滲(shen)碳(tan)淬(cui)火(huo)時零件(jian)的變(bian)形，同(tong)時還有利于(yu) 提高(gao)切削性(xing)(xing)能(neng)。正(zheng)火(huo)后(hou)轉機(ji)加(jia)工(gong)，先在車床(chuang)上(shang)對(dui)齒(chi)(chi)坯外圓(yuan)、端面進(jin)(jin)行(xing)粗、精(jing)加(jia)工(gong)后(hou)，在臥式銑床(chuang)上(shang)進(jin)(jin) 行(xing)銑齒(chi)(chi)，然后(hou)在插床(chuang)上(shang)插鍵(jian)槽(cao)，全部機(ji)加(jia)工(gong)完成后(hou)，進(jin)(jin)行(xing)滲(shen)碳(tan)淬(cui)火(huo)和(he)(he)低溫回火(huo)處(chu)(chu)理(li)(li)，進(jin)(jin)行(xing)后(hou)序(xu)處(chu)(chu) 理(li)(li)。該零件(jian)的工(gong)藝流程(cheng)為(wei)(wei)：正(zheng)火(huo)→車削→銑齒(chi)(chi)→插鍵(jian)槽(cao)→滲(shen)碳(tan)淬(cui)火(huo)及退火(huo)→噴砂→防銹處(chu)(chu)理(li)(li)。工(gong)藝難(nan)點為(wei)(wei)銑齒(chi)(chi)和(he)(he)熱處(chu)(chu)理(li)(li)工(gong)序(xu)。
