錐齒輪加工(gong)(gong)工(gong)(gong)藝流程和難點控制(zhi)

為(wei)確保(bao)齒(chi)(chi)(chi)輪熱處(chu)理(li)時，能夠減(jian)(jian)小變形(xing)并(bing)獲得(de)均勻的組織和較好的機(ji)械性能，在(zai)機(ji)加工(gong)(gong)前，先 對(dui)齒(chi)(chi)(chi)坯進(jin)行高溫(wen)正(zheng)火(huo)(huo)(huo)(huo)預處(chu)理(li)，可以使組織得(de)到(dao)細化，并(bing)減(jian)(jian)小滲碳(tan)(tan)淬火(huo)(huo)(huo)(huo)時零件(jian)的變形(xing)，同時還有利于(yu) 提高切削(xue)性能。正(zheng)火(huo)(huo)(huo)(huo)后(hou)轉機(ji)加工(gong)(gong)，先在(zai)車(che)(che)床上對(dui)齒(chi)(chi)(chi)坯外圓、端面進(jin)行粗、精加工(gong)(gong)后(hou)，在(zai)臥(wo)式銑床上進(jin) 行銑齒(chi)(chi)(chi)，然后(hou)在(zai)插床上插鍵(jian)槽，全部機(ji)加工(gong)(gong)完成后(hou)，進(jin)行滲碳(tan)(tan)淬火(huo)(huo)(huo)(huo)和低溫(wen)回火(huo)(huo)(huo)(huo)處(chu)理(li)，進(jin)行后(hou)序處(chu) 理(li)。該零件(jian)的工(gong)(gong)藝(yi)流程(cheng)為(wei)：正(zheng)火(huo)(huo)(huo)(huo)→車(che)(che)削(xue)→銑齒(chi)(chi)(chi)→插鍵(jian)槽→滲碳(tan)(tan)淬火(huo)(huo)(huo)(huo)及退火(huo)(huo)(huo)(huo)→噴(pen)砂(sha)→防銹(xiu)處(chu)理(li)。工(gong)(gong)藝(yi)難點為(wei)銑齒(chi)(chi)(chi)和熱處(chu)理(li)工(gong)(gong)序。
