具體參數

混凝土拖泵(beng)支重輪(lun)部件上(shang)有一配對錐齒(chi)(chi)輪(lun)，其(qi)中一個(ge)錐齒(chi)(chi)輪(lun)結構如圖1，材(cai)料為(wei)(wei)(wei)(wei)20CrMnTi，該齒(chi)(chi) 輪(lun)的主要技術參數(shu)(shu)為(wei)(wei)(wei)(wei)：大(da)端(duan)端(duan)面(mian)模數(shu)(shu)為(wei)(wei)(wei)(wei)4、齒(chi)(chi)數(shu)(shu)20、齒(chi)(chi)形(xing)角(jiao)為(wei)(wei)(wei)(wei)20°、切向變位系(xi)數(shu)(shu)為(wei)(wei)(wei)(wei)0、徑向變位系(xi)數(shu)(shu) 為(wei)(wei)(wei)(wei)-0.27、大(da)端(duan)齒(chi)(chi)高0.8mm、精度等級為(wei)(wei)(wei)(wei)8CB GB11365。由(you)于(yu)齒(chi)(chi)面(mian)硬度要求為(wei)(wei)(wei)(wei)HRC56~64，因(yin)此，齒(chi)(chi)輪(lun)需要進行滲碳淬火(huo)處理，滲層深(shen)度要求為(wei)(wei)(wei)(wei)0.8-1.2mm。

從技(ji)術要(yao)求和精度(du)等級(ji)來看，該齒(chi)(chi)輪的(de)加(jia)(jia)(jia)工(gong)精度(du) 等級(ji)要(yao)求不高，要(yao)確保該零件的(de)加(jia)(jia)(jia)工(gong)質量，關鍵在(zai)于(yu)解決好錐(zhui)齒(chi)(chi)加(jia)(jia)(jia)工(gong)和熱(re)處(chu)理(li)工(gong)藝環節(jie)，由于(yu)該零件 屬(shu)于(yu)試制(zhi)階段，為(wei)降(jiang)低加(jia)(jia)(jia)工(gong)成本(ben)，我(wo)們(men)決定在(zai)臥式(shi)銑床(chuang)上(shang)采用成形(xing)齒(chi)(chi)輪銑刀銑齒(chi)(chi)法加(jia)(jia)(jia)工(gong)該錐(zhui)齒(chi)(chi)輪，并通(tong)過制(zhi)訂(ding)合(he)理(li)的(de)熱(re)處(chu)理(li)工(gong)藝方法和參數來保證該齒(chi)(chi)輪的(de)加(jia)(jia)(jia)工(gong)質量。
