具體參數

混凝土拖(tuo)泵支(zhi)重輪(lun)(lun)部(bu)件上有一配(pei)對錐齒(chi)(chi)輪(lun)(lun)，其中一個錐齒(chi)(chi)輪(lun)(lun)結構如圖1，材料為(wei)(wei)(wei)20CrMnTi，該齒(chi)(chi) 輪(lun)(lun)的主要(yao)技術參數(shu)為(wei)(wei)(wei)：大(da)端(duan)端(duan)面(mian)模數(shu)為(wei)(wei)(wei)4、齒(chi)(chi)數(shu)20、齒(chi)(chi)形(xing)角為(wei)(wei)(wei)20°、切(qie)向變(bian)位系(xi)數(shu)為(wei)(wei)(wei)0、徑向變(bian)位系(xi)數(shu) 為(wei)(wei)(wei)-0.27、大(da)端(duan)齒(chi)(chi)高0.8mm、精度等(deng)級(ji)為(wei)(wei)(wei)8CB GB11365。由(you)于齒(chi)(chi)面(mian)硬(ying)度要(yao)求為(wei)(wei)(wei)HRC56~64，因此，齒(chi)(chi)輪(lun)(lun)需(xu)要(yao)進行(xing)滲(shen)碳淬(cui)火處(chu)理(li)，滲(shen)層深度要(yao)求為(wei)(wei)(wei)0.8-1.2mm。

從技術(shu)要(yao)求和精(jing)度等級來看，該齒輪的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)度 等級要(yao)求不高，要(yao)確(que)保該零件的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)質量，關鍵在(zai)于解決(jue)好錐(zhui)齒加(jia)(jia)工(gong)(gong)(gong)(gong)和熱處(chu)理工(gong)(gong)(gong)(gong)藝(yi)環節，由(you)于該零件 屬(shu)于試制階段，為(wei)降低(di)加(jia)(jia)工(gong)(gong)(gong)(gong)成本，我們決(jue)定在(zai)臥式銑(xian)床上采用成形齒輪銑(xian)刀銑(xian)齒法加(jia)(jia)工(gong)(gong)(gong)(gong)該錐(zhui)齒輪，并通(tong)過制訂合理的(de)熱處(chu)理工(gong)(gong)(gong)(gong)藝(yi)方法和參數來保證該齒輪的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)質量。
