具體參數

混凝土拖泵支重輪(lun)部件上(shang)有一配對錐齒(chi)輪(lun)，其中一個(ge)錐齒(chi)輪(lun)結構如圖1，材料(liao)為(wei)(wei)20CrMnTi，該(gai)齒(chi) 輪(lun)的主要(yao)技術參數(shu)(shu)為(wei)(wei)：大(da)端端面(mian)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(xiang)變(bian)位系數(shu)(shu)為(wei)(wei)0、徑(jing)向(xiang)變(bian)位系數(shu)(shu) 為(wei)(wei)-0.27、大(da)端齒(chi)高0.8mm、精度(du)(du)(du)等級為(wei)(wei)8CB GB11365。由(you)于齒(chi)面(mian)硬度(du)(du)(du)要(yao)求(qiu)為(wei)(wei)HRC56~64，因此，齒(chi)輪(lun)需要(yao)進行滲(shen)碳(tan)淬火處理，滲(shen)層深(shen)度(du)(du)(du)要(yao)求(qiu)為(wei)(wei)0.8-1.2mm。

從(cong)技(ji)術要求和精度等(deng)級來看，該(gai)齒(chi)輪(lun)(lun)的(de)(de)加(jia)(jia)工(gong)(gong)(gong)精度 等(deng)級要求不(bu)高，要確保該(gai)零件的(de)(de)加(jia)(jia)工(gong)(gong)(gong)質量(liang)，關鍵在(zai)于解決(jue)好錐齒(chi)加(jia)(jia)工(gong)(gong)(gong)和熱處(chu)理(li)工(gong)(gong)(gong)藝(yi)(yi)環節(jie)，由(you)于該(gai)零件 屬于試制階段，為降(jiang)低加(jia)(jia)工(gong)(gong)(gong)成本，我們決(jue)定在(zai)臥式銑(xian)床上(shang)采用成形齒(chi)輪(lun)(lun)銑(xian)刀銑(xian)齒(chi)法加(jia)(jia)工(gong)(gong)(gong)該(gai)錐齒(chi)輪(lun)(lun)，并通(tong)過制訂(ding)合理(li)的(de)(de)熱處(chu)理(li)工(gong)(gong)(gong)藝(yi)(yi)方法和參數來保證該(gai)齒(chi)輪(lun)(lun)的(de)(de)加(jia)(jia)工(gong)(gong)(gong)質量(liang)。
