具體參數
混(hun)凝土拖(tuo)泵支重輪(lun)部(bu)件上有(you)一配對錐(zhui)(zhui)齒(chi)輪(lun),其中一個錐(zhui)(zhui)齒(chi)輪(lun)結(jie)構如(ru)圖1,材料為(wei)20CrMnTi,該齒(chi) 輪(lun)的主要技術參數(shu)為(wei):大端端面模數(shu)為(wei)4、齒(chi)數(shu)20、齒(chi)形(xing)角為(wei)20°、切(qie)向(xiang)變(bian)位系數(shu)為(wei)0、徑(jing)向(xiang)變(bian)位系數(shu) 為(wei)-0.27、大端齒(chi)高0.8mm、精度等級為(wei)8CB GB11365。由于齒(chi)面硬度要求(qiu)為(wei)HRC56~64,因此,齒(chi)輪(lun)需(xu)要進行(xing)滲碳(tan)淬火(huo)處理(li),滲層(ceng)深度要求(qiu)為(wei)0.8-1.2mm。
從技術要求和(he)精度等級(ji)來(lai)看,該(gai)齒(chi)輪的(de)(de)加(jia)(jia)工(gong)(gong)(gong)精度 等級(ji)要求不高,要確保該(gai)零件(jian)的(de)(de)加(jia)(jia)工(gong)(gong)(gong)質量(liang),關鍵在于(yu)解決好錐(zhui)齒(chi)加(jia)(jia)工(gong)(gong)(gong)和(he)熱(re)處理(li)工(gong)(gong)(gong)藝(yi)(yi)環節(jie),由(you)于(yu)該(gai)零件(jian) 屬于(yu)試制階段,為(wei)降低加(jia)(jia)工(gong)(gong)(gong)成本,我們決定(ding)在臥(wo)式銑(xian)床上采用成形(xing)齒(chi)輪銑(xian)刀銑(xian)齒(chi)法加(jia)(jia)工(gong)(gong)(gong)該(gai)錐(zhui)齒(chi)輪,并通(tong)過(guo)制訂合(he)理(li)的(de)(de)熱(re)處理(li)工(gong)(gong)(gong)藝(yi)(yi)方法和(he)參數來(lai)保證該(gai)齒(chi)輪的(de)(de)加(jia)(jia)工(gong)(gong)(gong)質量(liang)。
