具體參數
混(hun)凝土拖泵支(zhi)重輪(lun)(lun)部件上有一配對錐齒輪(lun)(lun),其中一個錐齒輪(lun)(lun)結構(gou)如(ru)圖1,材料為(wei)(wei)20CrMnTi,該齒 輪(lun)(lun)的(de)主要技術(shu)參(can)數(shu)(shu)為(wei)(wei):大端端面(mian)模數(shu)(shu)為(wei)(wei)4、齒數(shu)(shu)20、齒形角為(wei)(wei)20°、切向變位系數(shu)(shu)為(wei)(wei)0、徑向變位系數(shu)(shu) 為(wei)(wei)-0.27、大端齒高0.8mm、精度等級為(wei)(wei)8CB GB11365。由于齒面(mian)硬度要求為(wei)(wei)HRC56~64,因此,齒輪(lun)(lun)需要進行滲(shen)碳淬(cui)火(huo)處(chu)理(li),滲(shen)層深(shen)度要求為(wei)(wei)0.8-1.2mm。
從技術要(yao)求(qiu)(qiu)和(he)精(jing)度等級來看,該齒(chi)(chi)輪(lun)的(de)加(jia)工(gong)(gong)精(jing)度 等級要(yao)求(qiu)(qiu)不高,要(yao)確保該零(ling)件的(de)加(jia)工(gong)(gong)質量,關鍵(jian)在于(yu)解決好(hao)錐齒(chi)(chi)加(jia)工(gong)(gong)和(he)熱處理工(gong)(gong)藝環節,由于(yu)該零(ling)件 屬于(yu)試制(zhi)階段,為降低加(jia)工(gong)(gong)成本,我(wo)們決定在臥式銑(xian)床(chuang)上采用成形齒(chi)(chi)輪(lun)銑(xian)刀銑(xian)齒(chi)(chi)法加(jia)工(gong)(gong)該錐齒(chi)(chi)輪(lun),并通過(guo)制(zhi)訂合理的(de)熱處理工(gong)(gong)藝方法和(he)參數(shu)來保證(zheng)該齒(chi)(chi)輪(lun)的(de)加(jia)工(gong)(gong)質量。
