具體參數
混(hun)凝(ning)土拖泵支重輪(lun)(lun)部件上有一配對錐齒(chi)輪(lun)(lun),其中一個錐齒(chi)輪(lun)(lun)結構如圖1,材料為(wei)(wei)(wei)20CrMnTi,該齒(chi) 輪(lun)(lun)的主要技術(shu)參數為(wei)(wei)(wei):大(da)(da)端(duan)端(duan)面模數為(wei)(wei)(wei)4、齒(chi)數20、齒(chi)形角為(wei)(wei)(wei)20°、切向(xiang)變位系數為(wei)(wei)(wei)0、徑向(xiang)變位系數 為(wei)(wei)(wei)-0.27、大(da)(da)端(duan)齒(chi)高0.8mm、精度等(deng)級為(wei)(wei)(wei)8CB GB11365。由(you)于齒(chi)面硬度要求為(wei)(wei)(wei)HRC56~64,因(yin)此(ci),齒(chi)輪(lun)(lun)需要進行滲(shen)碳淬火處(chu)理,滲(shen)層(ceng)深度要求為(wei)(wei)(wei)0.8-1.2mm。
從技術(shu)要求和精度(du)等級來看,該(gai)(gai)齒(chi)(chi)輪(lun)(lun)的(de)(de)加(jia)(jia)(jia)工(gong)(gong)精度(du) 等級要求不高,要確保該(gai)(gai)零件的(de)(de)加(jia)(jia)(jia)工(gong)(gong)質量(liang),關(guan)鍵(jian)在(zai)于解決(jue)好錐齒(chi)(chi)加(jia)(jia)(jia)工(gong)(gong)和熱處理(li)工(gong)(gong)藝(yi)(yi)環節,由(you)于該(gai)(gai)零件 屬于試(shi)制(zhi)階段,為降(jiang)低加(jia)(jia)(jia)工(gong)(gong)成本,我(wo)們決(jue)定在(zai)臥式銑(xian)床(chuang)上(shang)采(cai)用(yong)成形齒(chi)(chi)輪(lun)(lun)銑(xian)刀銑(xian)齒(chi)(chi)法(fa)加(jia)(jia)(jia)工(gong)(gong)該(gai)(gai)錐齒(chi)(chi)輪(lun)(lun),并通(tong)過制(zhi)訂合理(li)的(de)(de)熱處理(li)工(gong)(gong)藝(yi)(yi)方(fang)法(fa)和參數來保證該(gai)(gai)齒(chi)(chi)輪(lun)(lun)的(de)(de)加(jia)(jia)(jia)工(gong)(gong)質量(liang)。
