成形齒輪(lun)銑刀銑齒法的加工原理

成(cheng)形(xing)(xing)(xing)(xing)齒(chi)(chi)(chi)(chi)輪(lun)(lun)銑(xian)刀(dao)加工直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)屬于(yu)近似成(cheng)形(xing)(xing)(xing)(xing)法加工。因為直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)傘形(xing)(xing)(xing)(xing)，理論(lun)上應為球面(mian)漸(jian) 開(kai)(kai)線(xian)(xian)。由于(yu)球面(mian)不(bu)能展開(kai)(kai)成(cheng)平面(mian)，所以是近似的(de)(de)用(yong)背錐(zhui)(zhui)(zhui)(zhui)展開(kai)(kai)面(mian)上的(de)(de)當(dang)量漸(jian)開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)(xing)來設計成(cheng)形(xing)(xing)(xing)(xing)銑(xian)刀(dao)的(de)(de) 齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)(xing)。由于(yu)直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)齒(chi)(chi)(chi)(chi)廓是向錐(zhui)(zhui)(zhui)(zhui)頂收縮，因此沿節(jie)錐(zhui)(zhui)(zhui)(zhui)母線(xian)(xian)上各背錐(zhui)(zhui)(zhui)(zhui)展開(kai)(kai)面(mian)上的(de)(de)當(dang)量漸(jian)開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)(xing)曲 率不(bu)同。所以直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)銑(xian)刀(dao)的(de)(de)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)(xing)只能按照(zhao)節(jie)錐(zhui)(zhui)(zhui)(zhui)母線(xian)(xian)上某一(yi)(yi)背錐(zhui)(zhui)(zhui)(zhui)展開(kai)(kai)面(mian)上的(de)(de)當(dang)量漸(jian)開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)(xing)來設 計，加工出(chu)來的(de)(de)齒(chi)(chi)(chi)(chi)輪(lun)(lun)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)(xing)也(ye)只能在某一(yi)(yi)剖面(mian)中比較準確，其(qi)它剖面(mian)則(ze)有一(yi)(yi)定誤差。因此直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)成(cheng) 形(xing)(xing)(xing)(xing)銑(xian)刀(dao)適合粗加工和加工低精度的(de)(de)直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)。
