錐齒輪加工工藝流程和難(nan)點控制

為(wei)確保(bao)齒(chi)(chi)(chi)輪熱(re)處(chu)(chu)理(li)時(shi)，能(neng)夠減(jian)小(xiao)變(bian)(bian)形(xing)并獲得(de)均勻的組織(zhi)和(he)較好的機(ji)械性(xing)能(neng)，在(zai)機(ji)加工(gong)(gong)前，先 對(dui)齒(chi)(chi)(chi)坯進(jin)(jin)行(xing)(xing)高溫正火(huo)(huo)(huo)預處(chu)(chu)理(li)，可以(yi)使(shi)組織(zhi)得(de)到細化(hua)，并減(jian)小(xiao)滲(shen)碳淬火(huo)(huo)(huo)時(shi)零件的變(bian)(bian)形(xing)，同時(shi)還有(you)利于 提高切削(xue)性(xing)能(neng)。正火(huo)(huo)(huo)后(hou)(hou)轉機(ji)加工(gong)(gong)，先在(zai)車(che)床(chuang)上(shang)對(dui)齒(chi)(chi)(chi)坯外圓、端面進(jin)(jin)行(xing)(xing)粗(cu)、精(jing)加工(gong)(gong)后(hou)(hou)，在(zai)臥式銑(xian)(xian)床(chuang)上(shang)進(jin)(jin) 行(xing)(xing)銑(xian)(xian)齒(chi)(chi)(chi)，然后(hou)(hou)在(zai)插床(chuang)上(shang)插鍵槽(cao)，全部機(ji)加工(gong)(gong)完成后(hou)(hou)，進(jin)(jin)行(xing)(xing)滲(shen)碳淬火(huo)(huo)(huo)和(he)低溫回火(huo)(huo)(huo)處(chu)(chu)理(li)，進(jin)(jin)行(xing)(xing)后(hou)(hou)序處(chu)(chu) 理(li)。該零件的工(gong)(gong)藝流程為(wei)：正火(huo)(huo)(huo)→車(che)削(xue)→銑(xian)(xian)齒(chi)(chi)(chi)→插鍵槽(cao)→滲(shen)碳淬火(huo)(huo)(huo)及(ji)退火(huo)(huo)(huo)→噴(pen)砂→防銹(xiu)處(chu)(chu)理(li)。工(gong)(gong)藝難(nan)點為(wei)銑(xian)(xian)齒(chi)(chi)(chi)和(he)熱(re)處(chu)(chu)理(li)工(gong)(gong)序。
