具體參數
混凝土拖泵支(zhi)重輪部件(jian)上有一(yi)配(pei)對(dui)錐齒(chi)輪,其中一(yi)個錐齒(chi)輪結構如圖1,材(cai)料為(wei)20CrMnTi,該齒(chi) 輪的主要技(ji)術參數(shu)為(wei):大端(duan)端(duan)面(mian)模(mo)數(shu)為(wei)4、齒(chi)數(shu)20、齒(chi)形(xing)角為(wei)20°、切(qie)向(xiang)變位系(xi)數(shu)為(wei)0、徑向(xiang)變位系(xi)數(shu) 為(wei)-0.27、大端(duan)齒(chi)高0.8mm、精(jing)度(du)等級(ji)為(wei)8CB GB11365。由于齒(chi)面(mian)硬度(du)要求為(wei)HRC56~64,因此(ci),齒(chi)輪需要進行滲碳(tan)淬(cui)火處(chu)理(li),滲層深(shen)度(du)要求為(wei)0.8-1.2mm。
從技術要求(qiu)和精(jing)度等(deng)級來(lai)看,該(gai)(gai)齒(chi)輪(lun)的(de)加(jia)(jia)工(gong)(gong)(gong)精(jing)度 等(deng)級要求(qiu)不高,要確保該(gai)(gai)零(ling)件的(de)加(jia)(jia)工(gong)(gong)(gong)質(zhi)量(liang),關鍵在于(yu)解(jie)決好錐(zhui)齒(chi)加(jia)(jia)工(gong)(gong)(gong)和熱處理(li)工(gong)(gong)(gong)藝環節,由于(yu)該(gai)(gai)零(ling)件 屬于(yu)試制階段,為降低加(jia)(jia)工(gong)(gong)(gong)成本,我們決定在臥式銑床上采用成形齒(chi)輪(lun)銑刀銑齒(chi)法加(jia)(jia)工(gong)(gong)(gong)該(gai)(gai)錐(zhui)齒(chi)輪(lun),并通(tong)過制訂合理(li)的(de)熱處理(li)工(gong)(gong)(gong)藝方法和參數(shu)來(lai)保證該(gai)(gai)齒(chi)輪(lun)的(de)加(jia)(jia)工(gong)(gong)(gong)質(zhi)量(liang)。
