具體參數

混凝土拖泵支重輪(lun)(lun)部件上有一配對錐齒(chi)(chi)(chi)輪(lun)(lun)，其中(zhong)一個錐齒(chi)(chi)(chi)輪(lun)(lun)結構如(ru)圖1，材料為(wei)(wei)20CrMnTi，該齒(chi)(chi)(chi) 輪(lun)(lun)的主要(yao)技術參數(shu)為(wei)(wei)：大端(duan)端(duan)面模數(shu)為(wei)(wei)4、齒(chi)(chi)(chi)數(shu)20、齒(chi)(chi)(chi)形角為(wei)(wei)20°、切向(xiang)變(bian)位(wei)系(xi)數(shu)為(wei)(wei)0、徑向(xiang)變(bian)位(wei)系(xi)數(shu) 為(wei)(wei)-0.27、大端(duan)齒(chi)(chi)(chi)高0.8mm、精度等級(ji)為(wei)(wei)8CB GB11365。由于齒(chi)(chi)(chi)面硬度要(yao)求(qiu)為(wei)(wei)HRC56~64，因(yin)此，齒(chi)(chi)(chi)輪(lun)(lun)需(xu)要(yao)進(jin)行(xing)滲(shen)碳(tan)淬火處(chu)理，滲(shen)層深度要(yao)求(qiu)為(wei)(wei)0.8-1.2mm。

從技術要(yao)求(qiu)和精度等級來(lai)看，該(gai)齒輪(lun)的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)精度 等級要(yao)求(qiu)不高，要(yao)確保(bao)(bao)該(gai)零(ling)件的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)質量，關鍵在(zai)于解決好錐(zhui)齒加(jia)(jia)工(gong)(gong)(gong)(gong)和熱(re)處(chu)理(li)工(gong)(gong)(gong)(gong)藝(yi)環節，由于該(gai)零(ling)件 屬于試制階段，為降低加(jia)(jia)工(gong)(gong)(gong)(gong)成本，我(wo)們(men)決定在(zai)臥(wo)式銑床(chuang)上(shang)采用(yong)成形齒輪(lun)銑刀銑齒法加(jia)(jia)工(gong)(gong)(gong)(gong)該(gai)錐(zhui)齒輪(lun)，并(bing)通過制訂合理(li)的(de)熱(re)處(chu)理(li)工(gong)(gong)(gong)(gong)藝(yi)方(fang)法和參數來(lai)保(bao)(bao)證該(gai)齒輪(lun)的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)質量。
