具體參數
混凝土拖泵支重輪部件上有一配對錐齒(chi)(chi)輪,其中一個錐齒(chi)(chi)輪結構如圖1,材料(liao)為(wei)(wei)(wei)(wei)20CrMnTi,該齒(chi)(chi) 輪的主要(yao)(yao)技術參數(shu)為(wei)(wei)(wei)(wei):大端端面模數(shu)為(wei)(wei)(wei)(wei)4、齒(chi)(chi)數(shu)20、齒(chi)(chi)形(xing)角為(wei)(wei)(wei)(wei)20°、切向變位系數(shu)為(wei)(wei)(wei)(wei)0、徑向變位系數(shu) 為(wei)(wei)(wei)(wei)-0.27、大端齒(chi)(chi)高(gao)0.8mm、精度(du)等級為(wei)(wei)(wei)(wei)8CB GB11365。由于齒(chi)(chi)面硬度(du)要(yao)(yao)求為(wei)(wei)(wei)(wei)HRC56~64,因此,齒(chi)(chi)輪需要(yao)(yao)進行滲碳淬火處理,滲層深度(du)要(yao)(yao)求為(wei)(wei)(wei)(wei)0.8-1.2mm。
從技術要求和精(jing)(jing)度等(deng)級(ji)來看,該(gai)齒(chi)(chi)輪(lun)的(de)加(jia)(jia)工(gong)精(jing)(jing)度 等(deng)級(ji)要求不高,要確保(bao)該(gai)零件的(de)加(jia)(jia)工(gong)質(zhi)量(liang),關(guan)鍵(jian)在于解決(jue)好錐齒(chi)(chi)加(jia)(jia)工(gong)和熱處理工(gong)藝(yi)(yi)環節(jie),由于該(gai)零件 屬(shu)于試制階(jie)段(duan),為(wei)降低(di)加(jia)(jia)工(gong)成本(ben),我們決(jue)定在臥式銑(xian)床上采用(yong)成形齒(chi)(chi)輪(lun)銑(xian)刀銑(xian)齒(chi)(chi)法加(jia)(jia)工(gong)該(gai)錐齒(chi)(chi)輪(lun),并通過制訂合理的(de)熱處理工(gong)藝(yi)(yi)方法和參數來保(bao)證該(gai)齒(chi)(chi)輪(lun)的(de)加(jia)(jia)工(gong)質(zhi)量(liang)。
