具體參數
混凝土拖泵支重輪(lun)(lun)部件(jian)上有(you)一配對(dui)錐齒(chi)輪(lun)(lun),其中一個錐齒(chi)輪(lun)(lun)結構如圖1,材料為(wei)(wei)20CrMnTi,該齒(chi) 輪(lun)(lun)的主要技術參數(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(jiao)為(wei)(wei)20°、切(qie)向(xiang)變位系數(shu)(shu)為(wei)(wei)0、徑向(xiang)變位系數(shu)(shu) 為(wei)(wei)-0.27、大(da)端齒(chi)高0.8mm、精度等(deng)級為(wei)(wei)8CB GB11365。由(you)于齒(chi)面(mian)硬度要求為(wei)(wei)HRC56~64,因此(ci),齒(chi)輪(lun)(lun)需要進行(xing)滲碳淬火(huo)處理,滲層深度要求為(wei)(wei)0.8-1.2mm。
從技術要求和(he)精(jing)度等(deng)級(ji)來看(kan),該(gai)(gai)齒(chi)(chi)輪的加(jia)(jia)(jia)工(gong)(gong)精(jing)度 等(deng)級(ji)要求不高,要確保該(gai)(gai)零件的加(jia)(jia)(jia)工(gong)(gong)質(zhi)量(liang),關鍵在于(yu)解(jie)決好錐齒(chi)(chi)加(jia)(jia)(jia)工(gong)(gong)和(he)熱處理(li)工(gong)(gong)藝環節,由于(yu)該(gai)(gai)零件 屬于(yu)試制(zhi)(zhi)階(jie)段,為降(jiang)低加(jia)(jia)(jia)工(gong)(gong)成(cheng)(cheng)本,我們決定在臥式銑(xian)床上采用成(cheng)(cheng)形齒(chi)(chi)輪銑(xian)刀(dao)銑(xian)齒(chi)(chi)法加(jia)(jia)(jia)工(gong)(gong)該(gai)(gai)錐齒(chi)(chi)輪,并通過制(zhi)(zhi)訂合理(li)的熱處理(li)工(gong)(gong)藝方法和(he)參數(shu)來保證該(gai)(gai)齒(chi)(chi)輪的加(jia)(jia)(jia)工(gong)(gong)質(zhi)量(liang)。
