具體參數
混凝土(tu)拖泵支(zhi)重輪(lun)部件上有一配對錐齒(chi)(chi)輪(lun),其中(zhong)一個(ge)錐齒(chi)(chi)輪(lun)結構如圖1,材料為(wei)(wei)20CrMnTi,該齒(chi)(chi) 輪(lun)的主要(yao)(yao)技術參數為(wei)(wei):大端端面(mian)模(mo)數為(wei)(wei)4、齒(chi)(chi)數20、齒(chi)(chi)形角為(wei)(wei)20°、切向變位系數為(wei)(wei)0、徑向變位系數 為(wei)(wei)-0.27、大端齒(chi)(chi)高0.8mm、精度等(deng)級為(wei)(wei)8CB GB11365。由于齒(chi)(chi)面(mian)硬度要(yao)(yao)求為(wei)(wei)HRC56~64,因此,齒(chi)(chi)輪(lun)需(xu)要(yao)(yao)進行滲(shen)碳淬(cui)火處理(li),滲(shen)層深度要(yao)(yao)求為(wei)(wei)0.8-1.2mm。
從技術(shu)要(yao)求(qiu)和(he)精度(du)等級(ji)來看(kan),該(gai)齒輪(lun)的(de)(de)加(jia)工(gong)(gong)精度(du) 等級(ji)要(yao)求(qiu)不高,要(yao)確(que)保(bao)該(gai)零件的(de)(de)加(jia)工(gong)(gong)質量,關(guan)鍵(jian)在(zai)于解決好(hao)錐(zhui)齒加(jia)工(gong)(gong)和(he)熱(re)處(chu)理工(gong)(gong)藝環節,由于該(gai)零件 屬于試(shi)制階段,為降低(di)加(jia)工(gong)(gong)成本,我們決定(ding)在(zai)臥式(shi)銑(xian)床上采用成形齒輪(lun)銑(xian)刀銑(xian)齒法(fa)加(jia)工(gong)(gong)該(gai)錐(zhui)齒輪(lun),并通過制訂合理的(de)(de)熱(re)處(chu)理工(gong)(gong)藝方(fang)法(fa)和(he)參數來保(bao)證(zheng)該(gai)齒輪(lun)的(de)(de)加(jia)工(gong)(gong)質量。
