成形齒輪銑刀銑齒法的(de)加(jia)工原理

成形(xing)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)銑(xian)(xian)刀(dao)(dao)加(jia)工直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)屬于(yu)近似(si)(si)成形(xing)法加(jia)工。因為直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)的(de)(de)傘形(xing)，理論上應為球(qiu)面(mian)(mian)漸 開線(xian)。由于(yu)球(qiu)面(mian)(mian)不能(neng)(neng)(neng)展開成平面(mian)(mian)，所以是近似(si)(si)的(de)(de)用背錐(zhui)(zhui)(zhui)(zhui)展開面(mian)(mian)上的(de)(de)當量漸開線(xian)齒(chi)(chi)(chi)形(xing)來(lai)設(she)計成形(xing)銑(xian)(xian)刀(dao)(dao)的(de)(de) 齒(chi)(chi)(chi)形(xing)。由于(yu)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)的(de)(de)齒(chi)(chi)(chi)廓是向錐(zhui)(zhui)(zhui)(zhui)頂收縮(suo)，因此沿節錐(zhui)(zhui)(zhui)(zhui)母線(xian)上各背錐(zhui)(zhui)(zhui)(zhui)展開面(mian)(mian)上的(de)(de)當量漸開線(xian)齒(chi)(chi)(chi)形(xing)曲 率不同。所以直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)的(de)(de)銑(xian)(xian)刀(dao)(dao)的(de)(de)齒(chi)(chi)(chi)形(xing)只能(neng)(neng)(neng)按(an)照節錐(zhui)(zhui)(zhui)(zhui)母線(xian)上某一(yi)背錐(zhui)(zhui)(zhui)(zhui)展開面(mian)(mian)上的(de)(de)當量漸開線(xian)齒(chi)(chi)(chi)形(xing)來(lai)設(she) 計，加(jia)工出來(lai)的(de)(de)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)齒(chi)(chi)(chi)形(xing)也(ye)只能(neng)(neng)(neng)在某一(yi)剖(pou)面(mian)(mian)中比較準確，其它剖(pou)面(mian)(mian)則有一(yi)定誤(wu)差。因此直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)成 形(xing)銑(xian)(xian)刀(dao)(dao)適合(he)粗加(jia)工和加(jia)工低精度(du)的(de)(de)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)。
