具體參數

混凝土拖泵(beng)支重輪(lun)(lun)部件上有一配(pei)對錐齒(chi)輪(lun)(lun)，其中一個錐齒(chi)輪(lun)(lun)結(jie)構如圖1，材料(liao)為(wei)(wei)(wei)20CrMnTi，該齒(chi) 輪(lun)(lun)的(de)主要(yao)技術(shu)參數(shu)為(wei)(wei)(wei)：大(da)(da)端端面模數(shu)為(wei)(wei)(wei)4、齒(chi)數(shu)20、齒(chi)形角為(wei)(wei)(wei)20°、切(qie)向變位系(xi)數(shu)為(wei)(wei)(wei)0、徑向變位系(xi)數(shu) 為(wei)(wei)(wei)-0.27、大(da)(da)端齒(chi)高0.8mm、精度(du)等級為(wei)(wei)(wei)8CB GB11365。由(you)于齒(chi)面硬度(du)要(yao)求(qiu)為(wei)(wei)(wei)HRC56~64，因此，齒(chi)輪(lun)(lun)需要(yao)進行滲(shen)碳淬火處理，滲(shen)層深度(du)要(yao)求(qiu)為(wei)(wei)(wei)0.8-1.2mm。

從技(ji)術要求和精度等級來(lai)看，該齒(chi)輪的加工(gong)(gong)(gong)精度 等級要求不高，要確保該零(ling)件的加工(gong)(gong)(gong)質量(liang)，關鍵(jian)在于(yu)解決好錐齒(chi)加工(gong)(gong)(gong)和熱處理(li)工(gong)(gong)(gong)藝(yi)環節，由(you)于(yu)該零(ling)件 屬(shu)于(yu)試(shi)制(zhi)階段(duan)，為(wei)降低加工(gong)(gong)(gong)成(cheng)本，我(wo)們(men)決定在臥式銑(xian)(xian)床(chuang)上采(cai)用(yong)成(cheng)形齒(chi)輪銑(xian)(xian)刀銑(xian)(xian)齒(chi)法(fa)加工(gong)(gong)(gong)該錐齒(chi)輪，并通過制(zhi)訂合理(li)的熱處理(li)工(gong)(gong)(gong)藝(yi)方法(fa)和參(can)數(shu)來(lai)保證該齒(chi)輪的加工(gong)(gong)(gong)質量(liang)。
