具體參數

混凝土拖泵支重輪(lun)(lun)部(bu)件上有一配對(dui)錐齒輪(lun)(lun)，其中一個錐齒輪(lun)(lun)結構如圖1，材料為(wei)(wei)20CrMnTi，該齒 輪(lun)(lun)的主要技術參數(shu)為(wei)(wei)：大(da)端(duan)(duan)端(duan)(duan)面模數(shu)為(wei)(wei)4、齒數(shu)20、齒形角為(wei)(wei)20°、切(qie)向變位系(xi)數(shu)為(wei)(wei)0、徑向變位系(xi)數(shu) 為(wei)(wei)-0.27、大(da)端(duan)(duan)齒高0.8mm、精度(du)(du)等級為(wei)(wei)8CB GB11365。由(you)于齒面硬度(du)(du)要求(qiu)為(wei)(wei)HRC56~64，因(yin)此(ci)，齒輪(lun)(lun)需(xu)要進行滲碳淬火處(chu)理(li)，滲層深度(du)(du)要求(qiu)為(wei)(wei)0.8-1.2mm。

從技(ji)術要求和(he)精(jing)度(du)等級來看(kan)，該(gai)(gai)齒(chi)輪的(de)加(jia)工(gong)(gong)(gong)精(jing)度(du) 等級要求不(bu)高，要確(que)保該(gai)(gai)零(ling)件的(de)加(jia)工(gong)(gong)(gong)質量，關鍵在于(yu)解決好錐齒(chi)加(jia)工(gong)(gong)(gong)和(he)熱(re)處理工(gong)(gong)(gong)藝環節(jie)，由(you)于(yu)該(gai)(gai)零(ling)件 屬于(yu)試制(zhi)階段，為降(jiang)低加(jia)工(gong)(gong)(gong)成本(ben)，我們決定在臥式銑(xian)床上采用成形齒(chi)輪銑(xian)刀銑(xian)齒(chi)法加(jia)工(gong)(gong)(gong)該(gai)(gai)錐齒(chi)輪，并通過制(zhi)訂合理的(de)熱(re)處理工(gong)(gong)(gong)藝方法和(he)參數來保證該(gai)(gai)齒(chi)輪的(de)加(jia)工(gong)(gong)(gong)質量。
