錐齒輪加工(gong)(gong)工(gong)(gong)藝流(liu)程(cheng)和難(nan)點(dian)控(kong)制

為確保齒(chi)(chi)輪熱處(chu)(chu)(chu)(chu)理時(shi)，能夠減(jian)(jian)小(xiao)變形(xing)并(bing)(bing)獲得均勻(yun)的(de)組(zu)織(zhi)和較好的(de)機(ji)(ji)械(xie)性能，在機(ji)(ji)加(jia)(jia)工(gong)前，先(xian) 對齒(chi)(chi)坯(pi)進行(xing)高(gao)溫(wen)正火(huo)(huo)預(yu)處(chu)(chu)(chu)(chu)理，可以使(shi)組(zu)織(zhi)得到細化，并(bing)(bing)減(jian)(jian)小(xiao)滲碳淬火(huo)(huo)時(shi)零件(jian)的(de)變形(xing)，同時(shi)還有利于 提高(gao)切削(xue)性能。正火(huo)(huo)后(hou)轉機(ji)(ji)加(jia)(jia)工(gong)，先(xian)在車床(chuang)上對齒(chi)(chi)坯(pi)外圓、端面進行(xing)粗、精加(jia)(jia)工(gong)后(hou)，在臥(wo)式銑(xian)(xian)床(chuang)上進 行(xing)銑(xian)(xian)齒(chi)(chi)，然后(hou)在插床(chuang)上插鍵槽(cao)，全部機(ji)(ji)加(jia)(jia)工(gong)完成后(hou)，進行(xing)滲碳淬火(huo)(huo)和低溫(wen)回火(huo)(huo)處(chu)(chu)(chu)(chu)理，進行(xing)后(hou)序處(chu)(chu)(chu)(chu) 理。該零件(jian)的(de)工(gong)藝流程(cheng)為：正火(huo)(huo)→車削(xue)→銑(xian)(xian)齒(chi)(chi)→插鍵槽(cao)→滲碳淬火(huo)(huo)及退火(huo)(huo)→噴砂→防銹處(chu)(chu)(chu)(chu)理。工(gong)藝難點為銑(xian)(xian)齒(chi)(chi)和熱處(chu)(chu)(chu)(chu)理工(gong)序。
