錐(zhui)齒輪(lun)加工(gong)(gong)工(gong)(gong)藝流程(cheng)和難點(dian)控制

為(wei)確保齒(chi)(chi)輪熱(re)處(chu)(chu)理時，能夠減小變形(xing)并(bing)獲得均勻的組(zu)織和(he)較好的機(ji)械性(xing)能，在(zai)機(ji)加工(gong)(gong)(gong)(gong)(gong)前，先 對齒(chi)(chi)坯(pi)進行高(gao)溫(wen)正火(huo)(huo)預處(chu)(chu)理，可以使組(zu)織得到細化，并(bing)減小滲(shen)碳(tan)淬火(huo)(huo)時零件的變形(xing)，同(tong)時還有利(li)于 提(ti)高(gao)切削性(xing)能。正火(huo)(huo)后(hou)轉(zhuan)機(ji)加工(gong)(gong)(gong)(gong)(gong)，先在(zai)車(che)床(chuang)上對齒(chi)(chi)坯(pi)外(wai)圓(yuan)、端面進行粗、精加工(gong)(gong)(gong)(gong)(gong)后(hou)，在(zai)臥式銑(xian)床(chuang)上進 行銑(xian)齒(chi)(chi)，然后(hou)在(zai)插(cha)(cha)床(chuang)上插(cha)(cha)鍵槽，全部機(ji)加工(gong)(gong)(gong)(gong)(gong)完(wan)成后(hou)，進行滲(shen)碳(tan)淬火(huo)(huo)和(he)低(di)溫(wen)回(hui)火(huo)(huo)處(chu)(chu)理，進行后(hou)序處(chu)(chu) 理。該零件的工(gong)(gong)(gong)(gong)(gong)藝(yi)流程為(wei)：正火(huo)(huo)→車(che)削→銑(xian)齒(chi)(chi)→插(cha)(cha)鍵槽→滲(shen)碳(tan)淬火(huo)(huo)及退火(huo)(huo)→噴(pen)砂→防銹處(chu)(chu)理。工(gong)(gong)(gong)(gong)(gong)藝(yi)難點為(wei)銑(xian)齒(chi)(chi)和(he)熱(re)處(chu)(chu)理工(gong)(gong)(gong)(gong)(gong)序。
