成(cheng)形齒輪銑刀銑齒法的加(jia)工原理

成(cheng)形(xing)(xing)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)銑(xian)刀(dao)加工(gong)直(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)屬(shu)于近似成(cheng)形(xing)(xing)法加工(gong)。因(yin)為(wei)直(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)傘形(xing)(xing)，理論上應(ying)為(wei)球面(mian)(mian)(mian)(mian)(mian)漸(jian) 開線(xian)。由于球面(mian)(mian)(mian)(mian)(mian)不能(neng)展(zhan)開成(cheng)平面(mian)(mian)(mian)(mian)(mian)，所以是近似的(de)用背(bei)錐展(zhan)開面(mian)(mian)(mian)(mian)(mian)上的(de)當量漸(jian)開線(xian)齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)(xing)來(lai)設計(ji)成(cheng)形(xing)(xing)銑(xian)刀(dao)的(de) 齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)(xing)。由于直(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)齒(chi)(chi)(chi)(chi)(chi)(chi)廓是向(xiang)錐頂收縮，因(yin)此沿節錐母線(xian)上各背(bei)錐展(zhan)開面(mian)(mian)(mian)(mian)(mian)上的(de)當量漸(jian)開線(xian)齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)(xing)曲 率不同。所以直(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)銑(xian)刀(dao)的(de)齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)(xing)只能(neng)按照節錐母線(xian)上某一背(bei)錐展(zhan)開面(mian)(mian)(mian)(mian)(mian)上的(de)當量漸(jian)開線(xian)齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)(xing)來(lai)設 計(ji)，加工(gong)出來(lai)的(de)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)(xing)也只能(neng)在某一剖面(mian)(mian)(mian)(mian)(mian)中比較準確，其它剖面(mian)(mian)(mian)(mian)(mian)則(ze)有一定誤差。因(yin)此直(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)成(cheng) 形(xing)(xing)銑(xian)刀(dao)適(shi)合粗加工(gong)和加工(gong)低精度(du)的(de)直(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)。
