具體參數
混凝土拖(tuo)泵支(zhi)重輪(lun)部件上有一配對(dui)錐齒(chi)(chi)輪(lun),其(qi)中一個錐齒(chi)(chi)輪(lun)結構(gou)如圖1,材料為(wei)(wei)20CrMnTi,該齒(chi)(chi) 輪(lun)的主要技術參數(shu)為(wei)(wei):大(da)端端面模(mo)數(shu)為(wei)(wei)4、齒(chi)(chi)數(shu)20、齒(chi)(chi)形角為(wei)(wei)20°、切向(xiang)變位系數(shu)為(wei)(wei)0、徑(jing)向(xiang)變位系數(shu) 為(wei)(wei)-0.27、大(da)端齒(chi)(chi)高0.8mm、精度(du)等級(ji)為(wei)(wei)8CB GB11365。由于齒(chi)(chi)面硬(ying)度(du)要求為(wei)(wei)HRC56~64,因此,齒(chi)(chi)輪(lun)需要進行滲碳淬火(huo)處(chu)理,滲層深度(du)要求為(wei)(wei)0.8-1.2mm。
從技術要(yao)求(qiu)(qiu)和(he)精(jing)度等(deng)級(ji)來看(kan),該齒(chi)(chi)(chi)(chi)輪的加(jia)工(gong)精(jing)度 等(deng)級(ji)要(yao)求(qiu)(qiu)不高,要(yao)確保該零件(jian)的加(jia)工(gong)質(zhi)量,關(guan)鍵在于(yu)解決(jue)好錐齒(chi)(chi)(chi)(chi)加(jia)工(gong)和(he)熱(re)處理(li)工(gong)藝(yi)環節,由于(yu)該零件(jian) 屬于(yu)試制階段,為降低加(jia)工(gong)成(cheng)本,我們決(jue)定在臥式(shi)銑(xian)床上采用成(cheng)形齒(chi)(chi)(chi)(chi)輪銑(xian)刀銑(xian)齒(chi)(chi)(chi)(chi)法(fa)加(jia)工(gong)該錐齒(chi)(chi)(chi)(chi)輪,并通過制訂合(he)理(li)的熱(re)處理(li)工(gong)藝(yi)方(fang)法(fa)和(he)參數來保證該齒(chi)(chi)(chi)(chi)輪的加(jia)工(gong)質(zhi)量。
