具體參數
混凝土拖泵支重輪(lun)(lun)部(bu)件上有一配對(dui)錐(zhui)齒(chi)(chi)輪(lun)(lun),其中一個錐(zhui)齒(chi)(chi)輪(lun)(lun)結構(gou)如圖1,材料為20CrMnTi,該齒(chi)(chi) 輪(lun)(lun)的主要(yao)技術參數為:大(da)端(duan)端(duan)面模數為4、齒(chi)(chi)數20、齒(chi)(chi)形角為20°、切向變(bian)位系(xi)數為0、徑向變(bian)位系(xi)數 為-0.27、大(da)端(duan)齒(chi)(chi)高0.8mm、精度(du)等級為8CB GB11365。由于齒(chi)(chi)面硬度(du)要(yao)求(qiu)為HRC56~64,因(yin)此,齒(chi)(chi)輪(lun)(lun)需要(yao)進(jin)行滲(shen)碳(tan)淬火處理(li),滲(shen)層(ceng)深度(du)要(yao)求(qiu)為0.8-1.2mm。
從技術要求和(he)精(jing)(jing)度等(deng)級(ji)來看,該(gai)(gai)齒輪(lun)的加(jia)(jia)工(gong)(gong)精(jing)(jing)度 等(deng)級(ji)要求不(bu)高,要確保(bao)該(gai)(gai)零件的加(jia)(jia)工(gong)(gong)質量,關鍵在于(yu)解決(jue)好(hao)錐齒加(jia)(jia)工(gong)(gong)和(he)熱處理(li)(li)工(gong)(gong)藝(yi)環節,由于(yu)該(gai)(gai)零件 屬于(yu)試制階段,為降低加(jia)(jia)工(gong)(gong)成本,我(wo)們決(jue)定在臥(wo)式銑(xian)(xian)(xian)床上(shang)采用成形齒輪(lun)銑(xian)(xian)(xian)刀銑(xian)(xian)(xian)齒法(fa)(fa)加(jia)(jia)工(gong)(gong)該(gai)(gai)錐齒輪(lun),并通過制訂(ding)合(he)理(li)(li)的熱處理(li)(li)工(gong)(gong)藝(yi)方法(fa)(fa)和(he)參數來保(bao)證該(gai)(gai)齒輪(lun)的加(jia)(jia)工(gong)(gong)質量。
