具體參數
混(hun)凝土拖泵支重輪部(bu)件上(shang)有一(yi)配對錐(zhui)齒(chi)(chi)(chi)輪,其中(zhong)一(yi)個錐(zhui)齒(chi)(chi)(chi)輪結構如圖(tu)1,材料(liao)為20CrMnTi,該(gai)齒(chi)(chi)(chi) 輪的(de)主要技術參(can)數(shu)為:大端端面模數(shu)為4、齒(chi)(chi)(chi)數(shu)20、齒(chi)(chi)(chi)形角(jiao)為20°、切(qie)向(xiang)(xiang)變位(wei)系數(shu)為0、徑向(xiang)(xiang)變位(wei)系數(shu) 為-0.27、大端齒(chi)(chi)(chi)高(gao)0.8mm、精(jing)度等級為8CB GB11365。由于(yu)齒(chi)(chi)(chi)面硬度要求為HRC56~64,因(yin)此,齒(chi)(chi)(chi)輪需要進行(xing)滲碳淬火處理(li),滲層深度要求為0.8-1.2mm。
從技術(shu)要求(qiu)(qiu)和精(jing)度等(deng)級來(lai)看,該(gai)齒(chi)輪(lun)的(de)(de)加工(gong)(gong)精(jing)度 等(deng)級要求(qiu)(qiu)不(bu)高,要確(que)保該(gai)零件(jian)的(de)(de)加工(gong)(gong)質(zhi)量,關鍵在于(yu)解(jie)決(jue)好錐齒(chi)加工(gong)(gong)和熱處(chu)理(li)工(gong)(gong)藝環節,由于(yu)該(gai)零件(jian) 屬(shu)于(yu)試(shi)制階段,為(wei)降低(di)加工(gong)(gong)成本(ben),我們決(jue)定在臥(wo)式銑(xian)床(chuang)上采用(yong)成形齒(chi)輪(lun)銑(xian)刀銑(xian)齒(chi)法加工(gong)(gong)該(gai)錐齒(chi)輪(lun),并通過制訂合理(li)的(de)(de)熱處(chu)理(li)工(gong)(gong)藝方法和參(can)數來(lai)保證該(gai)齒(chi)輪(lun)的(de)(de)加工(gong)(gong)質(zhi)量。
