具體參數
混凝土拖泵支重輪(lun)部(bu)件上(shang)有一配對錐齒(chi)(chi)(chi)輪(lun),其(qi)中一個錐齒(chi)(chi)(chi)輪(lun)結構如圖(tu)1,材料為(wei)(wei)20CrMnTi,該齒(chi)(chi)(chi) 輪(lun)的主要技術參數(shu)為(wei)(wei):大(da)端(duan)端(duan)面(mian)模數(shu)為(wei)(wei)4、齒(chi)(chi)(chi)數(shu)20、齒(chi)(chi)(chi)形角為(wei)(wei)20°、切向(xiang)變位(wei)系數(shu)為(wei)(wei)0、徑向(xiang)變位(wei)系數(shu) 為(wei)(wei)-0.27、大(da)端(duan)齒(chi)(chi)(chi)高0.8mm、精度(du)等級(ji)為(wei)(wei)8CB GB11365。由于齒(chi)(chi)(chi)面(mian)硬(ying)度(du)要求為(wei)(wei)HRC56~64,因此,齒(chi)(chi)(chi)輪(lun)需要進行滲碳淬火(huo)處理,滲層深度(du)要求為(wei)(wei)0.8-1.2mm。
從技術(shu)要(yao)求(qiu)和(he)精(jing)度等級(ji)來看,該齒(chi)輪(lun)的加(jia)工(gong)(gong)精(jing)度 等級(ji)要(yao)求(qiu)不高(gao),要(yao)確(que)保該零件的加(jia)工(gong)(gong)質量,關鍵在于(yu)解決好錐(zhui)齒(chi)加(jia)工(gong)(gong)和(he)熱處理(li)工(gong)(gong)藝環(huan)節,由于(yu)該零件 屬于(yu)試制階段(duan),為降(jiang)低加(jia)工(gong)(gong)成本(ben),我(wo)們決定在臥(wo)式銑床上采(cai)用成形齒(chi)輪(lun)銑刀銑齒(chi)法(fa)(fa)加(jia)工(gong)(gong)該錐(zhui)齒(chi)輪(lun),并通過制訂合理(li)的熱處理(li)工(gong)(gong)藝方法(fa)(fa)和(he)參數來保證該齒(chi)輪(lun)的加(jia)工(gong)(gong)質量。
