具體參數
混凝土拖泵(beng)支重(zhong)輪部件上有一(yi)配對錐齒(chi)輪,其中一(yi)個錐齒(chi)輪結構如圖1,材料為20CrMnTi,該齒(chi) 輪的主要(yao)技(ji)術(shu)參(can)數(shu)(shu)為:大端(duan)(duan)端(duan)(duan)面(mian)模數(shu)(shu)為4、齒(chi)數(shu)(shu)20、齒(chi)形角為20°、切向變(bian)位系數(shu)(shu)為0、徑向變(bian)位系數(shu)(shu) 為-0.27、大端(duan)(duan)齒(chi)高(gao)0.8mm、精度等級為8CB GB11365。由(you)于齒(chi)面(mian)硬度要(yao)求(qiu)為HRC56~64,因此,齒(chi)輪需要(yao)進(jin)行滲碳淬火處理,滲層(ceng)深度要(yao)求(qiu)為0.8-1.2mm。
從(cong)技術(shu)要求(qiu)和精度等級(ji)來(lai)看(kan),該齒(chi)(chi)(chi)輪(lun)(lun)的(de)加工(gong)(gong)精度 等級(ji)要求(qiu)不(bu)高,要確(que)保(bao)該零件的(de)加工(gong)(gong)質量(liang)(liang),關鍵(jian)在于解決好(hao)錐齒(chi)(chi)(chi)加工(gong)(gong)和熱處理(li)工(gong)(gong)藝環節,由于該零件 屬于試制階段,為降低加工(gong)(gong)成(cheng)本,我們決定(ding)在臥式(shi)銑床(chuang)上采用成(cheng)形(xing)齒(chi)(chi)(chi)輪(lun)(lun)銑刀銑齒(chi)(chi)(chi)法(fa)加工(gong)(gong)該錐齒(chi)(chi)(chi)輪(lun)(lun),并(bing)通過(guo)制訂合理(li)的(de)熱處理(li)工(gong)(gong)藝方法(fa)和參數來(lai)保(bao)證該齒(chi)(chi)(chi)輪(lun)(lun)的(de)加工(gong)(gong)質量(liang)(liang)。
