錐齒輪加工工藝流程和難點控制

為確(que)保齒(chi)(chi)(chi)輪熱(re)處(chu)理(li)(li)時(shi)(shi)，能夠(gou)減(jian)小變形并(bing)獲得均勻的組(zu)織和(he)較好的機(ji)械性(xing)能，在機(ji)加工(gong)前(qian)，先(xian) 對(dui)齒(chi)(chi)(chi)坯進(jin)行(xing)高(gao)溫(wen)正火(huo)預處(chu)理(li)(li)，可(ke)以使組(zu)織得到細化，并(bing)減(jian)小滲碳淬火(huo)時(shi)(shi)零件(jian)的變形，同時(shi)(shi)還有利于 提高(gao)切削(xue)性(xing)能。正火(huo)后(hou)轉機(ji)加工(gong)，先(xian)在車(che)床(chuang)上(shang)對(dui)齒(chi)(chi)(chi)坯外圓(yuan)、端面進(jin)行(xing)粗(cu)、精加工(gong)后(hou)，在臥式(shi)銑(xian)(xian)床(chuang)上(shang)進(jin) 行(xing)銑(xian)(xian)齒(chi)(chi)(chi)，然后(hou)在插(cha)(cha)床(chuang)上(shang)插(cha)(cha)鍵槽(cao)，全(quan)部(bu)機(ji)加工(gong)完(wan)成后(hou)，進(jin)行(xing)滲碳淬火(huo)和(he)低溫(wen)回火(huo)處(chu)理(li)(li)，進(jin)行(xing)后(hou)序處(chu) 理(li)(li)。該零件(jian)的工(gong)藝(yi)(yi)流程為：正火(huo)→車(che)削(xue)→銑(xian)(xian)齒(chi)(chi)(chi)→插(cha)(cha)鍵槽(cao)→滲碳淬火(huo)及退火(huo)→噴砂→防銹(xiu)處(chu)理(li)(li)。工(gong)藝(yi)(yi)難點為銑(xian)(xian)齒(chi)(chi)(chi)和(he)熱(re)處(chu)理(li)(li)工(gong)序。
