具體參數
混凝土拖泵支重輪部件(jian)上有一(yi)配對錐齒(chi)輪,其中一(yi)個錐齒(chi)輪結構如(ru)圖1,材料為(wei)20CrMnTi,該(gai)齒(chi) 輪的主(zhu)要技術參(can)數(shu)(shu)為(wei):大(da)端端面(mian)模數(shu)(shu)為(wei)4、齒(chi)數(shu)(shu)20、齒(chi)形角為(wei)20°、切向(xiang)變(bian)位系數(shu)(shu)為(wei)0、徑向(xiang)變(bian)位系數(shu)(shu) 為(wei)-0.27、大(da)端齒(chi)高(gao)0.8mm、精度(du)等級為(wei)8CB GB11365。由于齒(chi)面(mian)硬度(du)要求為(wei)HRC56~64,因此,齒(chi)輪需(xu)要進(jin)行滲碳淬火(huo)處(chu)理(li),滲層深度(du)要求為(wei)0.8-1.2mm。
從(cong)技術要求和(he)精(jing)度(du)等級(ji)來看,該(gai)齒(chi)(chi)(chi)輪的(de)加(jia)工(gong)(gong)精(jing)度(du) 等級(ji)要求不高,要確保該(gai)零件(jian)的(de)加(jia)工(gong)(gong)質量,關鍵(jian)在于解決好(hao)錐齒(chi)(chi)(chi)加(jia)工(gong)(gong)和(he)熱(re)(re)處(chu)理(li)工(gong)(gong)藝環節(jie),由于該(gai)零件(jian) 屬于試制(zhi)(zhi)階段,為降低加(jia)工(gong)(gong)成本,我們決定在臥式銑床上(shang)采(cai)用成形齒(chi)(chi)(chi)輪銑刀銑齒(chi)(chi)(chi)法加(jia)工(gong)(gong)該(gai)錐齒(chi)(chi)(chi)輪,并通(tong)過制(zhi)(zhi)訂合(he)理(li)的(de)熱(re)(re)處(chu)理(li)工(gong)(gong)藝方(fang)法和(he)參數來保證該(gai)齒(chi)(chi)(chi)輪的(de)加(jia)工(gong)(gong)質量。
