錐齒(chi)輪(lun)加工(gong)(gong)工(gong)(gong)藝流程(cheng)和(he)難(nan)點控(kong)制
為(wei)確保齒輪熱處(chu)理時,能(neng)夠(gou)減(jian)小(xiao)變形(xing)并獲得均勻的(de)組織和較好的(de)機械(xie)性能(neng),在(zai)機加(jia)(jia)(jia)工(gong)前,先 對齒坯進(jin)(jin)行(xing)高溫(wen)正火(huo)(huo)(huo)預處(chu)理,可以使組織得到細化,并減(jian)小(xiao)滲碳淬火(huo)(huo)(huo)時零件的(de)變形(xing),同時還(huan)有利于(yu) 提高切(qie)削性能(neng)。正火(huo)(huo)(huo)后(hou)(hou)(hou)轉(zhuan)機加(jia)(jia)(jia)工(gong),先在(zai)車床上(shang)對齒坯外圓、端面進(jin)(jin)行(xing)粗(cu)、精加(jia)(jia)(jia)工(gong)后(hou)(hou)(hou),在(zai)臥式銑(xian)(xian)床上(shang)進(jin)(jin) 行(xing)銑(xian)(xian)齒,然(ran)后(hou)(hou)(hou)在(zai)插(cha)(cha)床上(shang)插(cha)(cha)鍵槽,全部機加(jia)(jia)(jia)工(gong)完成后(hou)(hou)(hou),進(jin)(jin)行(xing)滲碳淬火(huo)(huo)(huo)和低(di)溫(wen)回火(huo)(huo)(huo)處(chu)理,進(jin)(jin)行(xing)后(hou)(hou)(hou)序處(chu) 理。該零件的(de)工(gong)藝(yi)流程為(wei):正火(huo)(huo)(huo)→車削→銑(xian)(xian)齒→插(cha)(cha)鍵槽→滲碳淬火(huo)(huo)(huo)及退火(huo)(huo)(huo)→噴砂→防(fang)銹處(chu)理。工(gong)藝(yi)難點為(wei)銑(xian)(xian)齒和熱處(chu)理工(gong)序。
