具體參數
混(hun)凝土拖泵(beng)支重輪(lun)部(bu)件上有一配對錐齒(chi)(chi)輪(lun),其中一個錐齒(chi)(chi)輪(lun)結(jie)構如(ru)圖1,材料為(wei)(wei)(wei)20CrMnTi,該齒(chi)(chi) 輪(lun)的主要(yao)(yao)技(ji)術參數(shu)(shu)(shu)為(wei)(wei)(wei):大端(duan)端(duan)面模數(shu)(shu)(shu)為(wei)(wei)(wei)4、齒(chi)(chi)數(shu)(shu)(shu)20、齒(chi)(chi)形角(jiao)為(wei)(wei)(wei)20°、切向變位(wei)(wei)系(xi)數(shu)(shu)(shu)為(wei)(wei)(wei)0、徑(jing)向變位(wei)(wei)系(xi)數(shu)(shu)(shu) 為(wei)(wei)(wei)-0.27、大端(duan)齒(chi)(chi)高(gao)0.8mm、精度等級(ji)為(wei)(wei)(wei)8CB GB11365。由于齒(chi)(chi)面硬度要(yao)(yao)求為(wei)(wei)(wei)HRC56~64,因此(ci),齒(chi)(chi)輪(lun)需(xu)要(yao)(yao)進行滲(shen)碳淬火處理,滲(shen)層(ceng)深度要(yao)(yao)求為(wei)(wei)(wei)0.8-1.2mm。
從技術要(yao)求(qiu)和精(jing)度(du)等級來看,該(gai)(gai)(gai)齒(chi)輪(lun)(lun)的(de)加(jia)(jia)工(gong)精(jing)度(du) 等級要(yao)求(qiu)不(bu)高,要(yao)確保該(gai)(gai)(gai)零(ling)件(jian)的(de)加(jia)(jia)工(gong)質量(liang),關鍵在于(yu)解決(jue)好錐齒(chi)加(jia)(jia)工(gong)和熱(re)處(chu)理工(gong)藝環節,由(you)于(yu)該(gai)(gai)(gai)零(ling)件(jian) 屬于(yu)試制階段,為降低加(jia)(jia)工(gong)成本,我們決(jue)定(ding)在臥式銑(xian)床上采(cai)用成形(xing)齒(chi)輪(lun)(lun)銑(xian)刀銑(xian)齒(chi)法加(jia)(jia)工(gong)該(gai)(gai)(gai)錐齒(chi)輪(lun)(lun),并通(tong)過制訂合理的(de)熱(re)處(chu)理工(gong)藝方法和參數來保證該(gai)(gai)(gai)齒(chi)輪(lun)(lun)的(de)加(jia)(jia)工(gong)質量(liang)。
