錐齒輪加(jia)工工藝流(liu)程和難點控(kong)制

為(wei)(wei)(wei)確(que)保齒(chi)輪熱(re)處(chu)(chu)理時(shi)，能夠(gou)減(jian)(jian)小變形并(bing)獲得(de)均(jun)勻的(de)(de)組織和較好的(de)(de)機(ji)械性能，在機(ji)加(jia)工(gong)(gong)前，先 對齒(chi)坯進(jin)(jin)(jin)行高溫正(zheng)火(huo)預處(chu)(chu)理，可以使組織得(de)到細化，并(bing)減(jian)(jian)小滲碳淬火(huo)時(shi)零件(jian)(jian)的(de)(de)變形，同時(shi)還有利于 提高切削(xue)性能。正(zheng)火(huo)后轉機(ji)加(jia)工(gong)(gong)，先在車床上對齒(chi)坯外圓、端面進(jin)(jin)(jin)行粗、精加(jia)工(gong)(gong)后，在臥式銑(xian)(xian)床上進(jin)(jin)(jin) 行銑(xian)(xian)齒(chi)，然后在插(cha)床上插(cha)鍵槽(cao)，全部機(ji)加(jia)工(gong)(gong)完(wan)成(cheng)后，進(jin)(jin)(jin)行滲碳淬火(huo)和低溫回火(huo)處(chu)(chu)理，進(jin)(jin)(jin)行后序處(chu)(chu) 理。該零件(jian)(jian)的(de)(de)工(gong)(gong)藝流程為(wei)(wei)(wei)：正(zheng)火(huo)→車削(xue)→銑(xian)(xian)齒(chi)→插(cha)鍵槽(cao)→滲碳淬火(huo)及退火(huo)→噴(pen)砂→防(fang)銹處(chu)(chu)理。工(gong)(gong)藝難(nan)點(dian)為(wei)(wei)(wei)銑(xian)(xian)齒(chi)和熱(re)處(chu)(chu)理工(gong)(gong)序。
