錐齒輪加工工藝流程和難點控制
為(wei)確(que)保(bao)齒輪熱(re)處理(li)時,能夠減(jian)小(xiao)變形并(bing)獲得均勻的(de)組織(zhi)和較好的(de)機械性能,在(zai)機加工(gong)(gong)前,先 對齒坯進(jin)行(xing)(xing)(xing)高溫(wen)正火(huo)預處理(li),可以使組織(zhi)得到細化,并(bing)減(jian)小(xiao)滲(shen)(shen)碳(tan)淬火(huo)時零件(jian)的(de)變形,同時還有利(li)于 提高切削性能。正火(huo)后(hou)轉(zhuan)機加工(gong)(gong),先在(zai)車床(chuang)上對齒坯外圓、端面進(jin)行(xing)(xing)(xing)粗、精加工(gong)(gong)后(hou),在(zai)臥式(shi)銑床(chuang)上進(jin) 行(xing)(xing)(xing)銑齒,然后(hou)在(zai)插床(chuang)上插鍵槽(cao),全部機加工(gong)(gong)完成后(hou),進(jin)行(xing)(xing)(xing)滲(shen)(shen)碳(tan)淬火(huo)和低溫(wen)回火(huo)處理(li),進(jin)行(xing)(xing)(xing)后(hou)序處 理(li)。該零件(jian)的(de)工(gong)(gong)藝流程為(wei):正火(huo)→車削→銑齒→插鍵槽(cao)→滲(shen)(shen)碳(tan)淬火(huo)及退火(huo)→噴(pen)砂(sha)→防銹(xiu)處理(li)。工(gong)(gong)藝難點為(wei)銑齒和熱(re)處理(li)工(gong)(gong)序。
