錐齒輪(lun)加工(gong)工(gong)藝流程(cheng)和(he)難點控制(zhi)

為(wei)確保齒(chi)(chi)(chi)(chi)輪熱處(chu)(chu)理(li)時，能夠減(jian)(jian)小變(bian)形并獲得均勻(yun)的(de)組織和較好的(de)機械(xie)性能，在(zai)機加(jia)(jia)工(gong)前(qian)，先 對齒(chi)(chi)(chi)(chi)坯進(jin)(jin)(jin)行高溫(wen)正火(huo)預處(chu)(chu)理(li)，可以使組織得到細化，并減(jian)(jian)小滲碳淬(cui)火(huo)時零(ling)(ling)件(jian)的(de)變(bian)形，同(tong)時還有利于 提高切(qie)削性能。正火(huo)后(hou)(hou)轉機加(jia)(jia)工(gong)，先在(zai)車床(chuang)(chuang)上對齒(chi)(chi)(chi)(chi)坯外圓(yuan)、端面進(jin)(jin)(jin)行粗、精加(jia)(jia)工(gong)后(hou)(hou)，在(zai)臥式銑(xian)(xian)床(chuang)(chuang)上進(jin)(jin)(jin) 行銑(xian)(xian)齒(chi)(chi)(chi)(chi)，然后(hou)(hou)在(zai)插(cha)床(chuang)(chuang)上插(cha)鍵槽(cao)，全部機加(jia)(jia)工(gong)完成后(hou)(hou)，進(jin)(jin)(jin)行滲碳淬(cui)火(huo)和低溫(wen)回火(huo)處(chu)(chu)理(li)，進(jin)(jin)(jin)行后(hou)(hou)序處(chu)(chu) 理(li)。該零(ling)(ling)件(jian)的(de)工(gong)藝(yi)流程(cheng)為(wei)：正火(huo)→車削→銑(xian)(xian)齒(chi)(chi)(chi)(chi)→插(cha)鍵槽(cao)→滲碳淬(cui)火(huo)及退火(huo)→噴砂→防銹處(chu)(chu)理(li)。工(gong)藝(yi)難點為(wei)銑(xian)(xian)齒(chi)(chi)(chi)(chi)和熱處(chu)(chu)理(li)工(gong)序。
