具體參數
混凝土拖泵(beng)支(zhi)重輪(lun)部件(jian)上有一配對(dui)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun),其中一個錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)結構如圖1,材(cai)料為(wei)20CrMnTi,該齒(chi)(chi)(chi)(chi)(chi) 輪(lun)的主要技術參數(shu)為(wei):大端端面(mian)模數(shu)為(wei)4、齒(chi)(chi)(chi)(chi)(chi)數(shu)20、齒(chi)(chi)(chi)(chi)(chi)形角為(wei)20°、切(qie)向變位系(xi)數(shu)為(wei)0、徑向變位系(xi)數(shu) 為(wei)-0.27、大端齒(chi)(chi)(chi)(chi)(chi)高(gao)0.8mm、精度等(deng)級(ji)為(wei)8CB GB11365。由于(yu)齒(chi)(chi)(chi)(chi)(chi)面(mian)硬(ying)度要求為(wei)HRC56~64,因此,齒(chi)(chi)(chi)(chi)(chi)輪(lun)需(xu)要進行滲碳淬火(huo)處理,滲層深度要求為(wei)0.8-1.2mm。
從技術要(yao)求和(he)精度等級來看,該(gai)齒(chi)(chi)(chi)輪(lun)(lun)的加(jia)工(gong)精度 等級要(yao)求不高,要(yao)確(que)保該(gai)零件(jian)的加(jia)工(gong)質(zhi)量(liang),關鍵在(zai)于(yu)解決好錐齒(chi)(chi)(chi)加(jia)工(gong)和(he)熱(re)(re)處理(li)工(gong)藝環(huan)節,由(you)于(yu)該(gai)零件(jian) 屬于(yu)試制(zhi)階段,為降低(di)加(jia)工(gong)成(cheng)本,我們決定在(zai)臥(wo)式(shi)銑(xian)床上(shang)采用成(cheng)形齒(chi)(chi)(chi)輪(lun)(lun)銑(xian)刀銑(xian)齒(chi)(chi)(chi)法加(jia)工(gong)該(gai)錐齒(chi)(chi)(chi)輪(lun)(lun),并通過(guo)制(zhi)訂合理(li)的熱(re)(re)處理(li)工(gong)藝方法和(he)參數來保證(zheng)該(gai)齒(chi)(chi)(chi)輪(lun)(lun)的加(jia)工(gong)質(zhi)量(liang)。
