具體參數
混凝土拖泵(beng)支重(zhong)輪部件上有(you)一配對錐齒(chi)輪,其中一個錐齒(chi)輪結構(gou)如圖1,材料為(wei)(wei)20CrMnTi,該(gai)齒(chi) 輪的(de)主要(yao)技術參數為(wei)(wei):大(da)端(duan)(duan)(duan)端(duan)(duan)(duan)面(mian)模數為(wei)(wei)4、齒(chi)數20、齒(chi)形角為(wei)(wei)20°、切向變位系(xi)數為(wei)(wei)0、徑向變位系(xi)數 為(wei)(wei)-0.27、大(da)端(duan)(duan)(duan)齒(chi)高0.8mm、精度(du)等級為(wei)(wei)8CB GB11365。由(you)于齒(chi)面(mian)硬度(du)要(yao)求(qiu)為(wei)(wei)HRC56~64,因此,齒(chi)輪需要(yao)進行(xing)滲(shen)碳淬火處理,滲(shen)層(ceng)深度(du)要(yao)求(qiu)為(wei)(wei)0.8-1.2mm。
從技術要求(qiu)和(he)精度(du)等(deng)級(ji)來看,該齒輪(lun)(lun)的(de)(de)加(jia)工(gong)(gong)精度(du) 等(deng)級(ji)要求(qiu)不高,要確保該零件(jian)的(de)(de)加(jia)工(gong)(gong)質(zhi)量,關鍵在(zai)于解(jie)決好錐齒加(jia)工(gong)(gong)和(he)熱(re)處(chu)理工(gong)(gong)藝(yi)環節,由于該零件(jian) 屬于試(shi)制(zhi)階段(duan),為(wei)降低加(jia)工(gong)(gong)成本,我們決定在(zai)臥式銑床(chuang)上(shang)采用成形齒輪(lun)(lun)銑刀銑齒法加(jia)工(gong)(gong)該錐齒輪(lun)(lun),并通過(guo)制(zhi)訂合理的(de)(de)熱(re)處(chu)理工(gong)(gong)藝(yi)方法和(he)參(can)數來保證該齒輪(lun)(lun)的(de)(de)加(jia)工(gong)(gong)質(zhi)量。
