錐齒輪加工工藝流程和難(nan)點控(kong)制
為確(que)保齒輪熱處(chu)(chu)(chu)理(li)時(shi),能夠減小(xiao)(xiao)變(bian)形并(bing)獲得均勻的組織和較好的機械性能,在機加工(gong)前(qian),先(xian) 對(dui)齒坯(pi)進(jin)行(xing)(xing)高(gao)溫正火(huo)預處(chu)(chu)(chu)理(li),可以使組織得到(dao)細化,并(bing)減小(xiao)(xiao)滲碳淬(cui)火(huo)時(shi)零件(jian)的變(bian)形,同(tong)時(shi)還有利于 提(ti)高(gao)切削性能。正火(huo)后(hou)(hou)轉機加工(gong),先(xian)在車床(chuang)上對(dui)齒坯(pi)外圓、端面進(jin)行(xing)(xing)粗、精加工(gong)后(hou)(hou),在臥式銑床(chuang)上進(jin) 行(xing)(xing)銑齒,然(ran)后(hou)(hou)在插床(chuang)上插鍵槽,全部機加工(gong)完成后(hou)(hou),進(jin)行(xing)(xing)滲碳淬(cui)火(huo)和低(di)溫回火(huo)處(chu)(chu)(chu)理(li),進(jin)行(xing)(xing)后(hou)(hou)序(xu)處(chu)(chu)(chu) 理(li)。該(gai)零件(jian)的工(gong)藝流(liu)程為:正火(huo)→車削→銑齒→插鍵槽→滲碳淬(cui)火(huo)及(ji)退火(huo)→噴砂→防銹處(chu)(chu)(chu)理(li)。工(gong)藝難(nan)點(dian)為銑齒和熱處(chu)(chu)(chu)理(li)工(gong)序(xu)。
