成形(xing)齒輪銑刀銑齒法的加工原理

成(cheng)形(xing)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)銑(xian)刀(dao)(dao)加(jia)工直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)屬(shu)于近似(si)成(cheng)形(xing)法加(jia)工。因為直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)(de)傘(san)形(xing)，理論上應為球面(mian)(mian)(mian)漸 開(kai)線(xian)。由于球面(mian)(mian)(mian)不(bu)能展開(kai)成(cheng)平(ping)面(mian)(mian)(mian)，所(suo)以(yi)是(shi)近似(si)的(de)(de)(de)用背(bei)錐(zhui)展開(kai)面(mian)(mian)(mian)上的(de)(de)(de)當量漸開(kai)線(xian)齒(chi)(chi)(chi)(chi)(chi)形(xing)來設(she)計(ji)成(cheng)形(xing)銑(xian)刀(dao)(dao)的(de)(de)(de) 齒(chi)(chi)(chi)(chi)(chi)形(xing)。由于直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)廓是(shi)向錐(zhui)頂收縮，因此沿(yan)節錐(zhui)母(mu)線(xian)上各(ge)背(bei)錐(zhui)展開(kai)面(mian)(mian)(mian)上的(de)(de)(de)當量漸開(kai)線(xian)齒(chi)(chi)(chi)(chi)(chi)形(xing)曲 率不(bu)同。所(suo)以(yi)直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)(de)銑(xian)刀(dao)(dao)的(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)形(xing)只能按(an)照節錐(zhui)母(mu)線(xian)上某一(yi)背(bei)錐(zhui)展開(kai)面(mian)(mian)(mian)上的(de)(de)(de)當量漸開(kai)線(xian)齒(chi)(chi)(chi)(chi)(chi)形(xing)來設(she) 計(ji)，加(jia)工出來的(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)形(xing)也(ye)只能在某一(yi)剖面(mian)(mian)(mian)中比較(jiao)準確，其(qi)它(ta)剖面(mian)(mian)(mian)則(ze)有一(yi)定誤差(cha)。因此直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)成(cheng) 形(xing)銑(xian)刀(dao)(dao)適合(he)粗加(jia)工和加(jia)工低精度的(de)(de)(de)直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)。
