具體參數

混凝土拖泵支(zhi)重輪(lun)(lun)(lun)部件(jian)上有一配(pei)對錐(zhui)齒輪(lun)(lun)(lun)，其中一個(ge)錐(zhui)齒輪(lun)(lun)(lun)結(jie)構(gou)如圖1，材料為(wei)(wei)20CrMnTi，該齒 輪(lun)(lun)(lun)的(de)主要(yao)(yao)技(ji)術參數為(wei)(wei)：大(da)端(duan)端(duan)面模數為(wei)(wei)4、齒數20、齒形角為(wei)(wei)20°、切向變位(wei)系數為(wei)(wei)0、徑(jing)向變位(wei)系數 為(wei)(wei)-0.27、大(da)端(duan)齒高0.8mm、精度等級為(wei)(wei)8CB GB11365。由于(yu)齒面硬度要(yao)(yao)求為(wei)(wei)HRC56~64，因(yin)此，齒輪(lun)(lun)(lun)需(xu)要(yao)(yao)進行滲(shen)碳淬火處理，滲(shen)層(ceng)深度要(yao)(yao)求為(wei)(wei)0.8-1.2mm。

從技術要(yao)求和精度(du)等級(ji)來看，該齒(chi)(chi)輪的加(jia)工(gong)(gong)精度(du) 等級(ji)要(yao)求不高，要(yao)確保該零件的加(jia)工(gong)(gong)質量(liang)，關鍵(jian)在(zai)于解決好(hao)錐(zhui)齒(chi)(chi)加(jia)工(gong)(gong)和熱處(chu)(chu)理(li)工(gong)(gong)藝環節(jie)，由(you)于該零件 屬于試(shi)制(zhi)階段，為降(jiang)低加(jia)工(gong)(gong)成本，我(wo)們決定在(zai)臥式銑(xian)床上采(cai)用成形(xing)齒(chi)(chi)輪銑(xian)刀銑(xian)齒(chi)(chi)法加(jia)工(gong)(gong)該錐(zhui)齒(chi)(chi)輪，并通過制(zhi)訂合理(li)的熱處(chu)(chu)理(li)工(gong)(gong)藝方法和參數(shu)來保證(zheng)該齒(chi)(chi)輪的加(jia)工(gong)(gong)質量(liang)。
