具體參數
混(hun)凝土(tu)拖泵支(zhi)重輪(lun)部件上有一配對錐齒輪(lun),其中一個錐齒輪(lun)結構如圖1,材料為(wei)20CrMnTi,該齒 輪(lun)的(de)主要(yao)技術參數(shu)為(wei):大端(duan)端(duan)面(mian)模(mo)數(shu)為(wei)4、齒數(shu)20、齒形角(jiao)為(wei)20°、切向(xiang)(xiang)變位系數(shu)為(wei)0、徑向(xiang)(xiang)變位系數(shu) 為(wei)-0.27、大端(duan)齒高0.8mm、精度(du)(du)等級為(wei)8CB GB11365。由于齒面(mian)硬度(du)(du)要(yao)求為(wei)HRC56~64,因此,齒輪(lun)需要(yao)進(jin)行滲(shen)碳淬火(huo)處理(li),滲(shen)層深度(du)(du)要(yao)求為(wei)0.8-1.2mm。
從(cong)技術要(yao)求和(he)精度(du)(du)等(deng)級(ji)來看,該齒(chi)輪(lun)的加工(gong)(gong)精度(du)(du) 等(deng)級(ji)要(yao)求不高,要(yao)確保(bao)(bao)該零件的加工(gong)(gong)質(zhi)量,關鍵在(zai)于解決(jue)好錐齒(chi)加工(gong)(gong)和(he)熱處理工(gong)(gong)藝環節(jie),由于該零件 屬于試制階段(duan),為降低加工(gong)(gong)成本,我們決(jue)定在(zai)臥式銑(xian)床上(shang)采用成形(xing)齒(chi)輪(lun)銑(xian)刀銑(xian)齒(chi)法(fa)加工(gong)(gong)該錐齒(chi)輪(lun),并通過制訂合理的熱處理工(gong)(gong)藝方(fang)法(fa)和(he)參(can)數來保(bao)(bao)證該齒(chi)輪(lun)的加工(gong)(gong)質(zhi)量。
