具體參數
混凝(ning)土拖泵支重輪(lun)部件上有(you)一配對錐(zhui)齒(chi)輪(lun),其中(zhong)一個錐(zhui)齒(chi)輪(lun)結構如圖(tu)1,材料(liao)為(wei)(wei)20CrMnTi,該(gai)齒(chi) 輪(lun)的主要(yao)技術參(can)數(shu)(shu)(shu)為(wei)(wei):大(da)端端面(mian)模數(shu)(shu)(shu)為(wei)(wei)4、齒(chi)數(shu)(shu)(shu)20、齒(chi)形(xing)角(jiao)為(wei)(wei)20°、切(qie)向(xiang)變位系(xi)數(shu)(shu)(shu)為(wei)(wei)0、徑向(xiang)變位系(xi)數(shu)(shu)(shu) 為(wei)(wei)-0.27、大(da)端齒(chi)高(gao)0.8mm、精(jing)度(du)等(deng)級為(wei)(wei)8CB GB11365。由于齒(chi)面(mian)硬(ying)度(du)要(yao)求為(wei)(wei)HRC56~64,因此,齒(chi)輪(lun)需(xu)要(yao)進(jin)行滲碳淬火處(chu)理,滲層深度(du)要(yao)求為(wei)(wei)0.8-1.2mm。
從技術要求(qiu)和(he)精度等(deng)級來(lai)看,該(gai)齒(chi)(chi)(chi)輪(lun)的加(jia)(jia)工(gong)(gong)精度 等(deng)級要求(qiu)不(bu)高,要確保該(gai)零件的加(jia)(jia)工(gong)(gong)質量(liang),關(guan)鍵(jian)在(zai)于解決好錐齒(chi)(chi)(chi)加(jia)(jia)工(gong)(gong)和(he)熱(re)處(chu)理(li)工(gong)(gong)藝(yi)環(huan)節,由于該(gai)零件 屬于試制(zhi)階段,為降(jiang)低加(jia)(jia)工(gong)(gong)成本(ben),我們決定在(zai)臥(wo)式銑床上采用成形齒(chi)(chi)(chi)輪(lun)銑刀銑齒(chi)(chi)(chi)法加(jia)(jia)工(gong)(gong)該(gai)錐齒(chi)(chi)(chi)輪(lun),并通過制(zhi)訂合理(li)的熱(re)處(chu)理(li)工(gong)(gong)藝(yi)方法和(he)參數來(lai)保證該(gai)齒(chi)(chi)(chi)輪(lun)的加(jia)(jia)工(gong)(gong)質量(liang)。
