具體參數
混凝土拖泵(beng)支重輪(lun)部件上有一(yi)配對錐齒(chi)(chi)輪(lun),其(qi)中一(yi)個錐齒(chi)(chi)輪(lun)結構如圖(tu)1,材料為20CrMnTi,該齒(chi)(chi) 輪(lun)的主要(yao)技術(shu)參數(shu)為:大端(duan)端(duan)面模數(shu)為4、齒(chi)(chi)數(shu)20、齒(chi)(chi)形角為20°、切向變位系(xi)數(shu)為0、徑向變位系(xi)數(shu) 為-0.27、大端(duan)齒(chi)(chi)高0.8mm、精度等(deng)級為8CB GB11365。由于(yu)齒(chi)(chi)面硬度要(yao)求(qiu)為HRC56~64,因(yin)此,齒(chi)(chi)輪(lun)需要(yao)進行滲(shen)(shen)碳淬火處理,滲(shen)(shen)層深(shen)度要(yao)求(qiu)為0.8-1.2mm。
從技(ji)術要(yao)(yao)求和(he)精度(du)等級(ji)來看,該(gai)(gai)(gai)齒(chi)輪(lun)的(de)加(jia)工(gong)(gong)精度(du) 等級(ji)要(yao)(yao)求不高,要(yao)(yao)確保該(gai)(gai)(gai)零(ling)件(jian)的(de)加(jia)工(gong)(gong)質(zhi)量(liang),關鍵(jian)在(zai)于解決(jue)好(hao)錐(zhui)(zhui)齒(chi)加(jia)工(gong)(gong)和(he)熱(re)處(chu)理工(gong)(gong)藝環節(jie),由于該(gai)(gai)(gai)零(ling)件(jian) 屬于試(shi)制(zhi)階段(duan),為(wei)降低加(jia)工(gong)(gong)成(cheng)本,我們決(jue)定在(zai)臥(wo)式銑床上采用成(cheng)形齒(chi)輪(lun)銑刀(dao)銑齒(chi)法加(jia)工(gong)(gong)該(gai)(gai)(gai)錐(zhui)(zhui)齒(chi)輪(lun),并(bing)通(tong)過(guo)制(zhi)訂合理的(de)熱(re)處(chu)理工(gong)(gong)藝方(fang)法和(he)參數來保證該(gai)(gai)(gai)齒(chi)輪(lun)的(de)加(jia)工(gong)(gong)質(zhi)量(liang)。
