具體參數
混凝土拖泵支重輪(lun)(lun)部件上(shang)有一(yi)(yi)配(pei)對錐齒(chi)(chi)輪(lun)(lun),其中(zhong)一(yi)(yi)個錐齒(chi)(chi)輪(lun)(lun)結構如圖1,材料為(wei)(wei)20CrMnTi,該齒(chi)(chi) 輪(lun)(lun)的(de)主要技(ji)術(shu)參(can)數(shu)為(wei)(wei):大端端面(mian)模數(shu)為(wei)(wei)4、齒(chi)(chi)數(shu)20、齒(chi)(chi)形角為(wei)(wei)20°、切向變位(wei)系數(shu)為(wei)(wei)0、徑向變位(wei)系數(shu) 為(wei)(wei)-0.27、大端齒(chi)(chi)高0.8mm、精度(du)(du)等級為(wei)(wei)8CB GB11365。由于齒(chi)(chi)面(mian)硬度(du)(du)要求(qiu)為(wei)(wei)HRC56~64,因此,齒(chi)(chi)輪(lun)(lun)需要進(jin)行滲碳淬火處(chu)理,滲層深度(du)(du)要求(qiu)為(wei)(wei)0.8-1.2mm。
從(cong)技術要(yao)求和精(jing)(jing)度等(deng)(deng)級(ji)來看,該(gai)(gai)齒(chi)(chi)輪(lun)的(de)加工(gong)(gong)精(jing)(jing)度 等(deng)(deng)級(ji)要(yao)求不高,要(yao)確保(bao)該(gai)(gai)零件的(de)加工(gong)(gong)質量(liang),關鍵在于解決好錐齒(chi)(chi)加工(gong)(gong)和熱處(chu)理工(gong)(gong)藝環節,由于該(gai)(gai)零件 屬于試制階段,為(wei)降低加工(gong)(gong)成(cheng)本(ben),我(wo)們決定(ding)在臥式銑(xian)床(chuang)上采用成(cheng)形齒(chi)(chi)輪(lun)銑(xian)刀銑(xian)齒(chi)(chi)法(fa)加工(gong)(gong)該(gai)(gai)錐齒(chi)(chi)輪(lun),并通(tong)過制訂合理的(de)熱處(chu)理工(gong)(gong)藝方法(fa)和參數來保(bao)證該(gai)(gai)齒(chi)(chi)輪(lun)的(de)加工(gong)(gong)質量(liang)。
