具體參數
混凝土(tu)拖(tuo)泵支重輪(lun)部件(jian)上(shang)有一配對錐齒(chi)(chi)(chi)輪(lun),其中一個錐齒(chi)(chi)(chi)輪(lun)結(jie)構如圖1,材(cai)料為(wei)(wei)20CrMnTi,該齒(chi)(chi)(chi) 輪(lun)的(de)主(zhu)要(yao)技術參(can)數為(wei)(wei):大端端面模數為(wei)(wei)4、齒(chi)(chi)(chi)數20、齒(chi)(chi)(chi)形角為(wei)(wei)20°、切向(xiang)變位系數為(wei)(wei)0、徑向(xiang)變位系數 為(wei)(wei)-0.27、大端齒(chi)(chi)(chi)高0.8mm、精度等級為(wei)(wei)8CB GB11365。由于(yu)齒(chi)(chi)(chi)面硬度要(yao)求(qiu)為(wei)(wei)HRC56~64,因此,齒(chi)(chi)(chi)輪(lun)需要(yao)進行滲(shen)碳淬火處理,滲(shen)層深度要(yao)求(qiu)為(wei)(wei)0.8-1.2mm。
從技術(shu)要(yao)求(qiu)和(he)(he)精度(du)等級(ji)來(lai)看,該(gai)(gai)齒輪的加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)精度(du) 等級(ji)要(yao)求(qiu)不高,要(yao)確(que)保該(gai)(gai)零件(jian)的加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)質(zhi)量,關鍵(jian)在于(yu)(yu)解(jie)決(jue)好錐齒加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)和(he)(he)熱(re)處(chu)理工(gong)(gong)藝(yi)環節,由于(yu)(yu)該(gai)(gai)零件(jian) 屬于(yu)(yu)試制(zhi)階段,為降低加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)成(cheng)本(ben),我(wo)們決(jue)定在臥式銑床上采(cai)用成(cheng)形齒輪銑刀(dao)銑齒法加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)該(gai)(gai)錐齒輪,并(bing)通過制(zhi)訂合理的熱(re)處(chu)理工(gong)(gong)藝(yi)方法和(he)(he)參(can)數來(lai)保證(zheng)該(gai)(gai)齒輪的加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)質(zhi)量。
