具體參數

混凝土拖泵支重輪(lun)(lun)部(bu)件上有一(yi)配對錐齒(chi)(chi)輪(lun)(lun)，其(qi)中一(yi)個錐齒(chi)(chi)輪(lun)(lun)結構如圖1，材(cai)料為(wei)20CrMnTi，該齒(chi)(chi) 輪(lun)(lun)的主要技術參數(shu)(shu)為(wei)：大端(duan)(duan)端(duan)(duan)面模數(shu)(shu)為(wei)4、齒(chi)(chi)數(shu)(shu)20、齒(chi)(chi)形(xing)角為(wei)20°、切向變(bian)(bian)位系數(shu)(shu)為(wei)0、徑向變(bian)(bian)位系數(shu)(shu) 為(wei)-0.27、大端(duan)(duan)齒(chi)(chi)高0.8mm、精度等級(ji)為(wei)8CB GB11365。由于齒(chi)(chi)面硬度要求為(wei)HRC56~64，因此(ci)，齒(chi)(chi)輪(lun)(lun)需要進(jin)行(xing)滲(shen)碳淬火處(chu)理，滲(shen)層深度要求為(wei)0.8-1.2mm。

從技術(shu)要求(qiu)和精(jing)度等級來(lai)看，該(gai)(gai)(gai)齒(chi)(chi)(chi)輪的加(jia)(jia)工(gong)(gong)(gong)精(jing)度 等級要求(qiu)不(bu)高，要確保(bao)該(gai)(gai)(gai)零件(jian)的加(jia)(jia)工(gong)(gong)(gong)質量，關(guan)鍵(jian)在(zai)于(yu)解決(jue)好(hao)錐(zhui)齒(chi)(chi)(chi)加(jia)(jia)工(gong)(gong)(gong)和熱(re)處(chu)理(li)工(gong)(gong)(gong)藝環節，由(you)于(yu)該(gai)(gai)(gai)零件(jian) 屬于(yu)試制階段，為降低加(jia)(jia)工(gong)(gong)(gong)成(cheng)本，我們決(jue)定(ding)在(zai)臥(wo)式銑(xian)床上采(cai)用成(cheng)形齒(chi)(chi)(chi)輪銑(xian)刀銑(xian)齒(chi)(chi)(chi)法加(jia)(jia)工(gong)(gong)(gong)該(gai)(gai)(gai)錐(zhui)齒(chi)(chi)(chi)輪，并通過制訂合理(li)的熱(re)處(chu)理(li)工(gong)(gong)(gong)藝方法和參數來(lai)保(bao)證該(gai)(gai)(gai)齒(chi)(chi)(chi)輪的加(jia)(jia)工(gong)(gong)(gong)質量。
