具體參數
混凝土拖(tuo)泵(beng)支重輪(lun)(lun)部件上有一(yi)配對錐齒(chi)輪(lun)(lun),其中一(yi)個錐齒(chi)輪(lun)(lun)結構如(ru)圖1,材料為(wei)(wei)20CrMnTi,該(gai)齒(chi) 輪(lun)(lun)的(de)主要(yao)(yao)(yao)技術(shu)參數(shu)(shu)為(wei)(wei):大端端面模(mo)數(shu)(shu)為(wei)(wei)4、齒(chi)數(shu)(shu)20、齒(chi)形角(jiao)為(wei)(wei)20°、切向(xiang)變(bian)位系數(shu)(shu)為(wei)(wei)0、徑向(xiang)變(bian)位系數(shu)(shu) 為(wei)(wei)-0.27、大端齒(chi)高0.8mm、精度(du)等級為(wei)(wei)8CB GB11365。由于齒(chi)面硬度(du)要(yao)(yao)(yao)求(qiu)為(wei)(wei)HRC56~64,因此,齒(chi)輪(lun)(lun)需要(yao)(yao)(yao)進行滲碳淬火處理(li),滲層深度(du)要(yao)(yao)(yao)求(qiu)為(wei)(wei)0.8-1.2mm。
從(cong)技術要求(qiu)和精度(du)等級(ji)來(lai)看,該(gai)齒(chi)輪(lun)的(de)加(jia)工(gong)(gong)精度(du) 等級(ji)要求(qiu)不高,要確保(bao)該(gai)零件(jian)的(de)加(jia)工(gong)(gong)質量(liang),關鍵在于(yu)(yu)解(jie)決好(hao)錐齒(chi)加(jia)工(gong)(gong)和熱處(chu)理(li)(li)(li)工(gong)(gong)藝環節,由于(yu)(yu)該(gai)零件(jian) 屬于(yu)(yu)試制階段,為降低加(jia)工(gong)(gong)成本,我們決定在臥(wo)式銑(xian)床上采用成形齒(chi)輪(lun)銑(xian)刀銑(xian)齒(chi)法加(jia)工(gong)(gong)該(gai)錐齒(chi)輪(lun),并通(tong)過(guo)制訂合理(li)(li)(li)的(de)熱處(chu)理(li)(li)(li)工(gong)(gong)藝方法和參(can)數來(lai)保(bao)證該(gai)齒(chi)輪(lun)的(de)加(jia)工(gong)(gong)質量(liang)。
