錐齒輪加工工藝(yi)流程和難點(dian)控制

為(wei)確保齒(chi)(chi)輪熱處(chu)理時(shi)，能夠減小變(bian)形并獲得均勻的組織和較好(hao)的機械(xie)性(xing)能，在機加工(gong)(gong)前，先(xian) 對齒(chi)(chi)坯進(jin)行(xing)高溫(wen)正火(huo)預處(chu)理，可以使組織得到(dao)細化，并減小滲碳淬火(huo)時(shi)零(ling)件(jian)的變(bian)形，同時(shi)還有利(li)于 提高切(qie)削性(xing)能。正火(huo)后(hou)(hou)轉機加工(gong)(gong)，先(xian)在車床(chuang)上(shang)對齒(chi)(chi)坯外圓、端(duan)面(mian)進(jin)行(xing)粗、精加工(gong)(gong)后(hou)(hou)，在臥(wo)式銑(xian)床(chuang)上(shang)進(jin) 行(xing)銑(xian)齒(chi)(chi)，然后(hou)(hou)在插床(chuang)上(shang)插鍵槽，全(quan)部機加工(gong)(gong)完成(cheng)后(hou)(hou)，進(jin)行(xing)滲碳淬火(huo)和低溫(wen)回火(huo)處(chu)理，進(jin)行(xing)后(hou)(hou)序處(chu) 理。該零(ling)件(jian)的工(gong)(gong)藝流程為(wei)：正火(huo)→車削→銑(xian)齒(chi)(chi)→插鍵槽→滲碳淬火(huo)及退火(huo)→噴砂→防銹處(chu)理。工(gong)(gong)藝難點為(wei)銑(xian)齒(chi)(chi)和熱處(chu)理工(gong)(gong)序。
