錐齒輪(lun)加工(gong)工(gong)藝流程和難點控制

為確保(bao)齒輪熱(re)處(chu)(chu)(chu)理(li)時(shi)(shi)，能(neng)夠減小變形(xing)并(bing)獲得均(jun)勻的(de)組織和(he)較(jiao)好的(de)機(ji)械性能(neng)，在機(ji)加(jia)工(gong)(gong)前，先 對齒坯(pi)進(jin)(jin)行(xing)高(gao)(gao)溫正火預處(chu)(chu)(chu)理(li)，可以使組織得到細化，并(bing)減小滲(shen)碳(tan)淬(cui)(cui)火時(shi)(shi)零(ling)件的(de)變形(xing)，同時(shi)(shi)還(huan)有利于 提高(gao)(gao)切削(xue)性能(neng)。正火后(hou)(hou)轉機(ji)加(jia)工(gong)(gong)，先在車床上對齒坯(pi)外圓(yuan)、端面(mian)進(jin)(jin)行(xing)粗(cu)、精加(jia)工(gong)(gong)后(hou)(hou)，在臥(wo)式(shi)銑床上進(jin)(jin) 行(xing)銑齒，然后(hou)(hou)在插(cha)床上插(cha)鍵槽，全部機(ji)加(jia)工(gong)(gong)完成后(hou)(hou)，進(jin)(jin)行(xing)滲(shen)碳(tan)淬(cui)(cui)火和(he)低(di)溫回火處(chu)(chu)(chu)理(li)，進(jin)(jin)行(xing)后(hou)(hou)序(xu)處(chu)(chu)(chu) 理(li)。該零(ling)件的(de)工(gong)(gong)藝流程(cheng)為：正火→車削(xue)→銑齒→插(cha)鍵槽→滲(shen)碳(tan)淬(cui)(cui)火及退火→噴砂→防(fang)銹處(chu)(chu)(chu)理(li)。工(gong)(gong)藝難點為銑齒和(he)熱(re)處(chu)(chu)(chu)理(li)工(gong)(gong)序(xu)。
