具體參數

混凝(ning)土拖(tuo)泵(beng)支重(zhong)輪(lun)(lun)部件上有一配對錐(zhui)齒(chi)(chi)輪(lun)(lun)，其中一個錐(zhui)齒(chi)(chi)輪(lun)(lun)結構(gou)如圖1，材料為(wei)(wei)(wei)(wei)20CrMnTi，該齒(chi)(chi) 輪(lun)(lun)的主要(yao)技術參數為(wei)(wei)(wei)(wei)：大端(duan)端(duan)面模數為(wei)(wei)(wei)(wei)4、齒(chi)(chi)數20、齒(chi)(chi)形角為(wei)(wei)(wei)(wei)20°、切向變位系(xi)數為(wei)(wei)(wei)(wei)0、徑(jing)向變位系(xi)數 為(wei)(wei)(wei)(wei)-0.27、大端(duan)齒(chi)(chi)高0.8mm、精度(du)等(deng)級為(wei)(wei)(wei)(wei)8CB GB11365。由于齒(chi)(chi)面硬度(du)要(yao)求為(wei)(wei)(wei)(wei)HRC56~64，因此，齒(chi)(chi)輪(lun)(lun)需要(yao)進行滲(shen)碳淬火處(chu)理，滲(shen)層深度(du)要(yao)求為(wei)(wei)(wei)(wei)0.8-1.2mm。

從(cong)技術要(yao)求和精(jing)度(du)(du)等(deng)級來(lai)看，該(gai)齒(chi)(chi)(chi)輪(lun)的加工(gong)(gong)(gong)精(jing)度(du)(du) 等(deng)級要(yao)求不(bu)高，要(yao)確(que)保該(gai)零(ling)件的加工(gong)(gong)(gong)質量(liang)，關鍵在于(yu)解決(jue)好錐齒(chi)(chi)(chi)加工(gong)(gong)(gong)和熱處(chu)(chu)理工(gong)(gong)(gong)藝環節，由于(yu)該(gai)零(ling)件 屬于(yu)試制(zhi)階(jie)段，為降低加工(gong)(gong)(gong)成本，我們決(jue)定在臥式銑床上采用成形齒(chi)(chi)(chi)輪(lun)銑刀(dao)銑齒(chi)(chi)(chi)法加工(gong)(gong)(gong)該(gai)錐齒(chi)(chi)(chi)輪(lun)，并通過制(zhi)訂合理的熱處(chu)(chu)理工(gong)(gong)(gong)藝方法和參數來(lai)保證該(gai)齒(chi)(chi)(chi)輪(lun)的加工(gong)(gong)(gong)質量(liang)。
