錐齒輪(lun)加工(gong)工(gong)藝(yi)流程和難點控制(zhi)

為確保齒輪熱(re)處(chu)(chu)理(li)時，能夠減小變形(xing)并(bing)(bing)獲得均(jun)勻的組(zu)(zu)織(zhi)和(he)較好的機械性能，在(zai)機加工(gong)前，先(xian) 對齒坯進(jin)(jin)行(xing)(xing)高溫(wen)正火(huo)預處(chu)(chu)理(li)，可以使組(zu)(zu)織(zhi)得到細化(hua)，并(bing)(bing)減小滲(shen)(shen)(shen)碳淬(cui)(cui)火(huo)時零(ling)件的變形(xing)，同時還(huan)有利于 提高切削性能。正火(huo)后轉(zhuan)機加工(gong)，先(xian)在(zai)車(che)床上對齒坯外圓、端(duan)面進(jin)(jin)行(xing)(xing)粗(cu)、精加工(gong)后，在(zai)臥(wo)式銑(xian)(xian)床上進(jin)(jin) 行(xing)(xing)銑(xian)(xian)齒，然后在(zai)插床上插鍵槽，全部機加工(gong)完成后，進(jin)(jin)行(xing)(xing)滲(shen)(shen)(shen)碳淬(cui)(cui)火(huo)和(he)低溫(wen)回(hui)火(huo)處(chu)(chu)理(li)，進(jin)(jin)行(xing)(xing)后序處(chu)(chu) 理(li)。該零(ling)件的工(gong)藝(yi)流程為：正火(huo)→車(che)削→銑(xian)(xian)齒→插鍵槽→滲(shen)(shen)(shen)碳淬(cui)(cui)火(huo)及退(tui)火(huo)→噴砂→防銹(xiu)處(chu)(chu)理(li)。工(gong)藝(yi)難(nan)點(dian)為銑(xian)(xian)齒和(he)熱(re)處(chu)(chu)理(li)工(gong)序。
