具體參數
混凝土拖(tuo)泵支重輪(lun)部件上有一配對(dui)錐齒(chi)輪(lun),其(qi)中一個(ge)錐齒(chi)輪(lun)結構如圖(tu)1,材料為(wei)(wei)(wei)(wei)20CrMnTi,該(gai)齒(chi) 輪(lun)的(de)主(zhu)要(yao)技(ji)術參(can)數(shu)(shu)為(wei)(wei)(wei)(wei):大端端面(mian)模(mo)數(shu)(shu)為(wei)(wei)(wei)(wei)4、齒(chi)數(shu)(shu)20、齒(chi)形角(jiao)為(wei)(wei)(wei)(wei)20°、切向變位系數(shu)(shu)為(wei)(wei)(wei)(wei)0、徑向變位系數(shu)(shu) 為(wei)(wei)(wei)(wei)-0.27、大端齒(chi)高0.8mm、精度(du)(du)等級為(wei)(wei)(wei)(wei)8CB GB11365。由于齒(chi)面(mian)硬度(du)(du)要(yao)求(qiu)為(wei)(wei)(wei)(wei)HRC56~64,因此,齒(chi)輪(lun)需要(yao)進行(xing)滲(shen)碳淬火(huo)處理,滲(shen)層深度(du)(du)要(yao)求(qiu)為(wei)(wei)(wei)(wei)0.8-1.2mm。
從(cong)技術(shu)要(yao)求(qiu)和(he)精(jing)度等級來(lai)看,該(gai)(gai)齒(chi)(chi)(chi)輪的(de)加(jia)(jia)工精(jing)度 等級要(yao)求(qiu)不高,要(yao)確保該(gai)(gai)零(ling)件的(de)加(jia)(jia)工質(zhi)(zhi)量,關鍵(jian)在(zai)于解決(jue)好錐齒(chi)(chi)(chi)加(jia)(jia)工和(he)熱處理工藝(yi)環(huan)節(jie),由于該(gai)(gai)零(ling)件 屬于試制階(jie)段(duan),為降(jiang)低加(jia)(jia)工成(cheng)本,我們決(jue)定在(zai)臥式銑(xian)(xian)(xian)床上采用(yong)成(cheng)形齒(chi)(chi)(chi)輪銑(xian)(xian)(xian)刀(dao)銑(xian)(xian)(xian)齒(chi)(chi)(chi)法加(jia)(jia)工該(gai)(gai)錐齒(chi)(chi)(chi)輪,并通過制訂合理的(de)熱處理工藝(yi)方法和(he)參數(shu)來(lai)保證該(gai)(gai)齒(chi)(chi)(chi)輪的(de)加(jia)(jia)工質(zhi)(zhi)量。
