具體參數
混(hun)凝土拖泵支重輪部件上有一配對(dui)錐齒(chi)輪,其中一個錐齒(chi)輪結(jie)構如(ru)圖1,材(cai)料為(wei)20CrMnTi,該齒(chi) 輪的主(zhu)要(yao)技術參數為(wei):大端(duan)端(duan)面模數為(wei)4、齒(chi)數20、齒(chi)形角為(wei)20°、切向變位(wei)系數為(wei)0、徑向變位(wei)系數 為(wei)-0.27、大端(duan)齒(chi)高0.8mm、精度等級為(wei)8CB GB11365。由于齒(chi)面硬度要(yao)求(qiu)為(wei)HRC56~64,因此,齒(chi)輪需要(yao)進行滲(shen)碳淬(cui)火處理(li),滲(shen)層深度要(yao)求(qiu)為(wei)0.8-1.2mm。
從技(ji)術要(yao)求和精(jing)度等級(ji)來(lai)看,該(gai)齒(chi)(chi)輪(lun)(lun)的(de)加(jia)工(gong)(gong)精(jing)度 等級(ji)要(yao)求不高,要(yao)確保(bao)該(gai)零(ling)件(jian)的(de)加(jia)工(gong)(gong)質量(liang),關(guan)鍵在于(yu)(yu)解決(jue)好錐齒(chi)(chi)加(jia)工(gong)(gong)和熱(re)處(chu)理(li)工(gong)(gong)藝(yi)環節,由于(yu)(yu)該(gai)零(ling)件(jian) 屬于(yu)(yu)試(shi)制階段,為降低加(jia)工(gong)(gong)成本,我們(men)決(jue)定在臥式銑床上采用(yong)成形(xing)齒(chi)(chi)輪(lun)(lun)銑刀(dao)銑齒(chi)(chi)法(fa)加(jia)工(gong)(gong)該(gai)錐齒(chi)(chi)輪(lun)(lun),并通(tong)過(guo)制訂合(he)理(li)的(de)熱(re)處(chu)理(li)工(gong)(gong)藝(yi)方法(fa)和參數來(lai)保(bao)證(zheng)該(gai)齒(chi)(chi)輪(lun)(lun)的(de)加(jia)工(gong)(gong)質量(liang)。
