錐(zhui)齒輪加(jia)工(gong)(gong)工(gong)(gong)藝流(liu)程和難點控制(zhi)

為確保齒(chi)(chi)(chi)輪熱處(chu)(chu)理(li)時，能夠減小變形并獲得(de)均勻的組織和(he)較(jiao)好(hao)的機械性(xing)(xing)能，在(zai)(zai)機加(jia)工前，先(xian)(xian) 對齒(chi)(chi)(chi)坯進行(xing)高(gao)溫正火(huo)(huo)預處(chu)(chu)理(li)，可(ke)以使(shi)組織得(de)到(dao)細(xi)化，并減小滲(shen)碳淬火(huo)(huo)時零(ling)(ling)件(jian)的變形，同(tong)時還有利于 提高(gao)切削(xue)性(xing)(xing)能。正火(huo)(huo)后轉機加(jia)工，先(xian)(xian)在(zai)(zai)車(che)床上對齒(chi)(chi)(chi)坯外(wai)圓、端(duan)面進行(xing)粗、精加(jia)工后，在(zai)(zai)臥式銑(xian)床上進 行(xing)銑(xian)齒(chi)(chi)(chi)，然后在(zai)(zai)插床上插鍵槽，全部機加(jia)工完成后，進行(xing)滲(shen)碳淬火(huo)(huo)和(he)低溫回(hui)火(huo)(huo)處(chu)(chu)理(li)，進行(xing)后序處(chu)(chu) 理(li)。該零(ling)(ling)件(jian)的工藝(yi)流(liu)程為：正火(huo)(huo)→車(che)削(xue)→銑(xian)齒(chi)(chi)(chi)→插鍵槽→滲(shen)碳淬火(huo)(huo)及退火(huo)(huo)→噴(pen)砂→防(fang)銹處(chu)(chu)理(li)。工藝(yi)難(nan)點為銑(xian)齒(chi)(chi)(chi)和(he)熱處(chu)(chu)理(li)工序。
