具體參數
混凝(ning)土拖(tuo)泵支重輪部件上有一配對(dui)錐(zhui)齒輪,其中(zhong)一個錐(zhui)齒輪結構(gou)如圖1,材(cai)料為(wei)(wei)20CrMnTi,該齒 輪的主要(yao)技術參數(shu)(shu)(shu)為(wei)(wei):大端端面模數(shu)(shu)(shu)為(wei)(wei)4、齒數(shu)(shu)(shu)20、齒形角為(wei)(wei)20°、切(qie)向(xiang)變位系數(shu)(shu)(shu)為(wei)(wei)0、徑向(xiang)變位系數(shu)(shu)(shu) 為(wei)(wei)-0.27、大端齒高(gao)0.8mm、精度等級為(wei)(wei)8CB GB11365。由于齒面硬度要(yao)求為(wei)(wei)HRC56~64,因此(ci),齒輪需要(yao)進行滲(shen)碳淬(cui)火處理,滲(shen)層深度要(yao)求為(wei)(wei)0.8-1.2mm。
從技(ji)術要求(qiu)和精(jing)度(du)等級(ji)來看,該(gai)(gai)齒(chi)輪的加(jia)(jia)(jia)工(gong)(gong)精(jing)度(du) 等級(ji)要求(qiu)不高,要確保該(gai)(gai)零(ling)件的加(jia)(jia)(jia)工(gong)(gong)質(zhi)量,關鍵在(zai)于(yu)(yu)解(jie)決好錐(zhui)齒(chi)加(jia)(jia)(jia)工(gong)(gong)和熱處理工(gong)(gong)藝(yi)環節(jie),由于(yu)(yu)該(gai)(gai)零(ling)件 屬于(yu)(yu)試制(zhi)階段,為(wei)降(jiang)低加(jia)(jia)(jia)工(gong)(gong)成(cheng)(cheng)本,我們決定在(zai)臥式銑(xian)床上采用成(cheng)(cheng)形齒(chi)輪銑(xian)刀銑(xian)齒(chi)法加(jia)(jia)(jia)工(gong)(gong)該(gai)(gai)錐(zhui)齒(chi)輪,并通過制(zhi)訂合理的熱處理工(gong)(gong)藝(yi)方(fang)法和參(can)數(shu)來保證該(gai)(gai)齒(chi)輪的加(jia)(jia)(jia)工(gong)(gong)質(zhi)量。
