具體參數
混凝土拖泵支(zhi)重(zhong)輪(lun)部(bu)件(jian)上有(you)一配對錐齒(chi)輪(lun),其中一個錐齒(chi)輪(lun)結構如圖1,材料為(wei)(wei)20CrMnTi,該齒(chi) 輪(lun)的主要(yao)技(ji)術參(can)數為(wei)(wei):大端(duan)(duan)端(duan)(duan)面(mian)模數為(wei)(wei)4、齒(chi)數20、齒(chi)形角為(wei)(wei)20°、切(qie)向(xiang)變(bian)位系(xi)數為(wei)(wei)0、徑向(xiang)變(bian)位系(xi)數 為(wei)(wei)-0.27、大端(duan)(duan)齒(chi)高0.8mm、精度等級為(wei)(wei)8CB GB11365。由于齒(chi)面(mian)硬(ying)度要(yao)求為(wei)(wei)HRC56~64,因此,齒(chi)輪(lun)需要(yao)進行滲碳淬火處理,滲層深度要(yao)求為(wei)(wei)0.8-1.2mm。
從技術要(yao)(yao)求和(he)精度(du)等(deng)級來看,該齒(chi)(chi)(chi)輪的(de)加(jia)(jia)(jia)工(gong)精度(du) 等(deng)級要(yao)(yao)求不高,要(yao)(yao)確保該零件(jian)的(de)加(jia)(jia)(jia)工(gong)質(zhi)量(liang),關鍵在于(yu)解(jie)決好錐(zhui)齒(chi)(chi)(chi)加(jia)(jia)(jia)工(gong)和(he)熱(re)處理工(gong)藝(yi)環(huan)節(jie),由于(yu)該零件(jian) 屬(shu)于(yu)試制(zhi)階(jie)段,為降低加(jia)(jia)(jia)工(gong)成(cheng)本(ben),我們(men)決定(ding)在臥式銑(xian)(xian)(xian)床上采用(yong)成(cheng)形(xing)齒(chi)(chi)(chi)輪銑(xian)(xian)(xian)刀銑(xian)(xian)(xian)齒(chi)(chi)(chi)法(fa)加(jia)(jia)(jia)工(gong)該錐(zhui)齒(chi)(chi)(chi)輪,并通過制(zhi)訂合(he)理的(de)熱(re)處理工(gong)藝(yi)方(fang)法(fa)和(he)參數(shu)來保證該齒(chi)(chi)(chi)輪的(de)加(jia)(jia)(jia)工(gong)質(zhi)量(liang)。
