具體參數

混凝土拖(tuo)泵支(zhi)重輪部件上有一配對錐(zhui)齒(chi)輪，其中(zhong)一個錐(zhui)齒(chi)輪結(jie)構如圖1，材料為(wei)(wei)(wei)20CrMnTi，該齒(chi) 輪的主要(yao)技術參數為(wei)(wei)(wei)：大(da)(da)端(duan)(duan)端(duan)(duan)面模數為(wei)(wei)(wei)4、齒(chi)數20、齒(chi)形角(jiao)為(wei)(wei)(wei)20°、切向變(bian)位系(xi)數為(wei)(wei)(wei)0、徑向變(bian)位系(xi)數 為(wei)(wei)(wei)-0.27、大(da)(da)端(duan)(duan)齒(chi)高0.8mm、精(jing)度(du)等級為(wei)(wei)(wei)8CB GB11365。由(you)于(yu)齒(chi)面硬度(du)要(yao)求為(wei)(wei)(wei)HRC56~64，因此，齒(chi)輪需要(yao)進行滲碳淬火處(chu)理，滲層深度(du)要(yao)求為(wei)(wei)(wei)0.8-1.2mm。

從技術要(yao)求(qiu)和(he)精(jing)度等(deng)級(ji)來(lai)看，該(gai)齒輪的加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)度 等(deng)級(ji)要(yao)求(qiu)不高，要(yao)確保(bao)該(gai)零件的加(jia)(jia)(jia)工(gong)(gong)(gong)質量(liang)，關(guan)鍵在于(yu)解(jie)決好錐齒加(jia)(jia)(jia)工(gong)(gong)(gong)和(he)熱(re)處理(li)工(gong)(gong)(gong)藝環節，由于(yu)該(gai)零件 屬于(yu)試制階段，為降低加(jia)(jia)(jia)工(gong)(gong)(gong)成本，我們決定在臥式(shi)銑床上采(cai)用成形齒輪銑刀銑齒法加(jia)(jia)(jia)工(gong)(gong)(gong)該(gai)錐齒輪，并通過(guo)制訂合(he)理(li)的熱(re)處理(li)工(gong)(gong)(gong)藝方(fang)法和(he)參(can)數來(lai)保(bao)證該(gai)齒輪的加(jia)(jia)(jia)工(gong)(gong)(gong)質量(liang)。
