具體參數
混凝土拖泵支重輪部件上有(you)一(yi)配對錐(zhui)(zhui)齒(chi)輪,其(qi)中(zhong)一(yi)個錐(zhui)(zhui)齒(chi)輪結構如圖1,材料為(wei)(wei)(wei)20CrMnTi,該齒(chi) 輪的主要(yao)技術參數(shu)為(wei)(wei)(wei):大端端面模數(shu)為(wei)(wei)(wei)4、齒(chi)數(shu)20、齒(chi)形角為(wei)(wei)(wei)20°、切(qie)向變(bian)位(wei)系(xi)數(shu)為(wei)(wei)(wei)0、徑(jing)向變(bian)位(wei)系(xi)數(shu) 為(wei)(wei)(wei)-0.27、大端齒(chi)高(gao)0.8mm、精度等級為(wei)(wei)(wei)8CB GB11365。由于齒(chi)面硬度要(yao)求(qiu)為(wei)(wei)(wei)HRC56~64,因此,齒(chi)輪需要(yao)進行(xing)滲(shen)碳淬火(huo)處理,滲(shen)層深度要(yao)求(qiu)為(wei)(wei)(wei)0.8-1.2mm。
從技術要(yao)求和(he)精(jing)(jing)度(du)等(deng)級來(lai)看,該(gai)齒輪(lun)的(de)加(jia)工(gong)(gong)精(jing)(jing)度(du) 等(deng)級要(yao)求不高,要(yao)確保該(gai)零件(jian)的(de)加(jia)工(gong)(gong)質量(liang),關(guan)鍵在于解決好(hao)錐齒加(jia)工(gong)(gong)和(he)熱處理工(gong)(gong)藝(yi)環節,由于該(gai)零件(jian) 屬于試制(zhi)階段,為(wei)降低加(jia)工(gong)(gong)成本,我(wo)們決定在臥式銑床上(shang)采用(yong)成形齒輪(lun)銑刀(dao)銑齒法(fa)加(jia)工(gong)(gong)該(gai)錐齒輪(lun),并通過制(zhi)訂合理的(de)熱處理工(gong)(gong)藝(yi)方(fang)法(fa)和(he)參數(shu)來(lai)保證該(gai)齒輪(lun)的(de)加(jia)工(gong)(gong)質量(liang)。
