具體參數
混凝土拖(tuo)泵支重輪(lun)部(bu)件上有一配對錐齒(chi)(chi)(chi)輪(lun),其中(zhong)一個錐齒(chi)(chi)(chi)輪(lun)結構如(ru)圖1,材料為(wei)(wei)20CrMnTi,該齒(chi)(chi)(chi) 輪(lun)的主要技術參數為(wei)(wei):大(da)端端面(mian)模數為(wei)(wei)4、齒(chi)(chi)(chi)數20、齒(chi)(chi)(chi)形(xing)角為(wei)(wei)20°、切(qie)向(xiang)變位(wei)(wei)系(xi)數為(wei)(wei)0、徑向(xiang)變位(wei)(wei)系(xi)數 為(wei)(wei)-0.27、大(da)端齒(chi)(chi)(chi)高0.8mm、精度等級為(wei)(wei)8CB GB11365。由于齒(chi)(chi)(chi)面(mian)硬(ying)度要求為(wei)(wei)HRC56~64,因此,齒(chi)(chi)(chi)輪(lun)需要進行滲碳淬火處理,滲層深度要求為(wei)(wei)0.8-1.2mm。
從(cong)技術要求(qiu)和精度等(deng)級來(lai)看,該齒(chi)輪(lun)(lun)的(de)加(jia)工(gong)(gong)精度 等(deng)級要求(qiu)不高,要確(que)保(bao)該零件的(de)加(jia)工(gong)(gong)質量,關鍵(jian)在于解(jie)決(jue)好錐齒(chi)加(jia)工(gong)(gong)和熱處理(li)工(gong)(gong)藝環節(jie),由于該零件 屬于試制階(jie)段,為降低加(jia)工(gong)(gong)成(cheng)本,我們決(jue)定在臥式銑(xian)床上采用成(cheng)形齒(chi)輪(lun)(lun)銑(xian)刀銑(xian)齒(chi)法加(jia)工(gong)(gong)該錐齒(chi)輪(lun)(lun),并通過制訂合理(li)的(de)熱處理(li)工(gong)(gong)藝方法和參數來(lai)保(bao)證該齒(chi)輪(lun)(lun)的(de)加(jia)工(gong)(gong)質量。
