具體參數

混凝土拖泵支重(zhong)輪(lun)部件上(shang)有一(yi)配對錐齒(chi)輪(lun)，其中一(yi)個錐齒(chi)輪(lun)結構如(ru)圖(tu)1，材料(liao)為(wei)(wei)20CrMnTi，該(gai)齒(chi) 輪(lun)的(de)主要(yao)技術參數(shu)為(wei)(wei)：大(da)端端面模數(shu)為(wei)(wei)4、齒(chi)數(shu)20、齒(chi)形(xing)角為(wei)(wei)20°、切向(xiang)變位系(xi)數(shu)為(wei)(wei)0、徑向(xiang)變位系(xi)數(shu) 為(wei)(wei)-0.27、大(da)端齒(chi)高0.8mm、精度(du)等級為(wei)(wei)8CB GB11365。由(you)于齒(chi)面硬度(du)要(yao)求為(wei)(wei)HRC56~64，因此(ci)，齒(chi)輪(lun)需要(yao)進行滲碳(tan)淬火處(chu)理(li)，滲層深度(du)要(yao)求為(wei)(wei)0.8-1.2mm。

從技術要(yao)求(qiu)和精度(du)等(deng)級來(lai)看，該(gai)齒(chi)(chi)(chi)輪的(de)加(jia)(jia)工(gong)(gong)(gong)精度(du) 等(deng)級要(yao)求(qiu)不高，要(yao)確保該(gai)零件的(de)加(jia)(jia)工(gong)(gong)(gong)質(zhi)量，關(guan)鍵在(zai)于解決(jue)好錐(zhui)齒(chi)(chi)(chi)加(jia)(jia)工(gong)(gong)(gong)和熱處(chu)理工(gong)(gong)(gong)藝環節，由(you)于該(gai)零件 屬于試(shi)制階段，為降低加(jia)(jia)工(gong)(gong)(gong)成本(ben)，我們決(jue)定(ding)在(zai)臥(wo)式銑床(chuang)上采(cai)用成形齒(chi)(chi)(chi)輪銑刀銑齒(chi)(chi)(chi)法加(jia)(jia)工(gong)(gong)(gong)該(gai)錐(zhui)齒(chi)(chi)(chi)輪，并通過制訂合理的(de)熱處(chu)理工(gong)(gong)(gong)藝方法和參數來(lai)保證該(gai)齒(chi)(chi)(chi)輪的(de)加(jia)(jia)工(gong)(gong)(gong)質(zhi)量。
