錐齒輪加工工藝流程和難(nan)點控制
為(wei)(wei)確(que)保齒(chi)輪熱(re)處理時,能(neng)夠(gou)減小變形并(bing)獲得均勻(yun)的(de)(de)組(zu)(zu)織和較好的(de)(de)機械性(xing)能(neng),在機加(jia)工(gong)(gong)前,先(xian) 對齒(chi)坯進(jin)行(xing)高(gao)溫正火(huo)預處理,可(ke)以使(shi)組(zu)(zu)織得到(dao)細化,并(bing)減小滲碳(tan)(tan)淬火(huo)時零件的(de)(de)變形,同時還(huan)有利于(yu) 提高(gao)切(qie)削性(xing)能(neng)。正火(huo)后(hou)(hou)轉機加(jia)工(gong)(gong),先(xian)在車床(chuang)上對齒(chi)坯外圓、端面進(jin)行(xing)粗、精(jing)加(jia)工(gong)(gong)后(hou)(hou),在臥式銑床(chuang)上進(jin) 行(xing)銑齒(chi),然后(hou)(hou)在插床(chuang)上插鍵槽,全部(bu)機加(jia)工(gong)(gong)完成(cheng)后(hou)(hou),進(jin)行(xing)滲碳(tan)(tan)淬火(huo)和低溫回(hui)火(huo)處理,進(jin)行(xing)后(hou)(hou)序(xu)處 理。該零件的(de)(de)工(gong)(gong)藝(yi)流(liu)程為(wei)(wei):正火(huo)→車削→銑齒(chi)→插鍵槽→滲碳(tan)(tan)淬火(huo)及(ji)退火(huo)→噴(pen)砂(sha)→防銹處理。工(gong)(gong)藝(yi)難點為(wei)(wei)銑齒(chi)和熱(re)處理工(gong)(gong)序(xu)。
