具體參數
混凝土拖泵支重(zhong)輪(lun)部件上有一配對錐齒輪(lun),其中(zhong)一個錐齒輪(lun)結構(gou)如圖(tu)1,材料為(wei)(wei)20CrMnTi,該齒 輪(lun)的主要(yao)技術參數(shu)(shu)為(wei)(wei):大端端面(mian)模數(shu)(shu)為(wei)(wei)4、齒數(shu)(shu)20、齒形(xing)角為(wei)(wei)20°、切(qie)向(xiang)變位系數(shu)(shu)為(wei)(wei)0、徑向(xiang)變位系數(shu)(shu) 為(wei)(wei)-0.27、大端齒高0.8mm、精度等級(ji)為(wei)(wei)8CB GB11365。由于齒面(mian)硬度要(yao)求(qiu)為(wei)(wei)HRC56~64,因此,齒輪(lun)需要(yao)進行滲(shen)(shen)碳淬火處(chu)理,滲(shen)(shen)層深度要(yao)求(qiu)為(wei)(wei)0.8-1.2mm。
從技術要求和精度(du)等(deng)級(ji)來看,該(gai)(gai)齒(chi)(chi)輪(lun)的加工(gong)(gong)精度(du) 等(deng)級(ji)要求不高(gao),要確保該(gai)(gai)零件(jian)的加工(gong)(gong)質量(liang)(liang),關鍵在于解決好錐齒(chi)(chi)加工(gong)(gong)和熱處理(li)工(gong)(gong)藝環節,由于該(gai)(gai)零件(jian) 屬(shu)于試(shi)制階段,為降低加工(gong)(gong)成本,我們決定在臥式銑(xian)床上(shang)采用(yong)成形齒(chi)(chi)輪(lun)銑(xian)刀銑(xian)齒(chi)(chi)法加工(gong)(gong)該(gai)(gai)錐齒(chi)(chi)輪(lun),并通過制訂合理(li)的熱處理(li)工(gong)(gong)藝方(fang)法和參(can)數來保證該(gai)(gai)齒(chi)(chi)輪(lun)的加工(gong)(gong)質量(liang)(liang)。
