具體參數
混(hun)凝土拖泵支重(zhong)輪(lun)(lun)(lun)部件上有一配(pei)對錐(zhui)齒(chi)輪(lun)(lun)(lun),其中一個錐(zhui)齒(chi)輪(lun)(lun)(lun)結構(gou)如圖(tu)1,材料(liao)為(wei)(wei)20CrMnTi,該齒(chi) 輪(lun)(lun)(lun)的(de)主要(yao)(yao)技術參數(shu)(shu)為(wei)(wei):大(da)端(duan)端(duan)面模數(shu)(shu)為(wei)(wei)4、齒(chi)數(shu)(shu)20、齒(chi)形角為(wei)(wei)20°、切(qie)向變位(wei)系(xi)數(shu)(shu)為(wei)(wei)0、徑(jing)向變位(wei)系(xi)數(shu)(shu) 為(wei)(wei)-0.27、大(da)端(duan)齒(chi)高0.8mm、精(jing)度(du)等級為(wei)(wei)8CB GB11365。由于齒(chi)面硬度(du)要(yao)(yao)求為(wei)(wei)HRC56~64,因此,齒(chi)輪(lun)(lun)(lun)需要(yao)(yao)進行(xing)滲碳淬火處(chu)理,滲層深度(du)要(yao)(yao)求為(wei)(wei)0.8-1.2mm。
從技術(shu)要(yao)求和精度等級來看,該齒(chi)輪的(de)加(jia)(jia)工(gong)(gong)精度 等級要(yao)求不高,要(yao)確保(bao)該零件的(de)加(jia)(jia)工(gong)(gong)質量(liang),關(guan)鍵在于解決好(hao)錐齒(chi)加(jia)(jia)工(gong)(gong)和熱(re)處理(li)工(gong)(gong)藝(yi)環節,由于該零件 屬于試制階段(duan),為降低加(jia)(jia)工(gong)(gong)成本,我們決定在臥(wo)式銑床上(shang)采用成形齒(chi)輪銑刀銑齒(chi)法加(jia)(jia)工(gong)(gong)該錐齒(chi)輪,并通(tong)過制訂合理(li)的(de)熱(re)處理(li)工(gong)(gong)藝(yi)方法和參(can)數來保(bao)證該齒(chi)輪的(de)加(jia)(jia)工(gong)(gong)質量(liang)。
