成形齒輪銑刀銑齒法的加工原理

成形(xing)(xing)齒(chi)(chi)(chi)(chi)輪(lun)銑刀加(jia)工直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)屬于(yu)近(jin)似成形(xing)(xing)法加(jia)工。因為直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)(de)傘形(xing)(xing)，理(li)論上應為球面漸(jian)(jian) 開(kai)(kai)線(xian)(xian)(xian)。由(you)于(yu)球面不能展(zhan)(zhan)開(kai)(kai)成平面，所(suo)以是近(jin)似的(de)(de)(de)用背錐(zhui)展(zhan)(zhan)開(kai)(kai)面上的(de)(de)(de)當量漸(jian)(jian)開(kai)(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)來(lai)(lai)設計成形(xing)(xing)銑刀的(de)(de)(de) 齒(chi)(chi)(chi)(chi)形(xing)(xing)。由(you)于(yu)直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)(de)齒(chi)(chi)(chi)(chi)廓是向錐(zhui)頂收縮，因此(ci)沿節錐(zhui)母線(xian)(xian)(xian)上各(ge)背錐(zhui)展(zhan)(zhan)開(kai)(kai)面上的(de)(de)(de)當量漸(jian)(jian)開(kai)(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)曲(qu) 率不同。所(suo)以直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)(de)銑刀的(de)(de)(de)齒(chi)(chi)(chi)(chi)形(xing)(xing)只能按照節錐(zhui)母線(xian)(xian)(xian)上某一背錐(zhui)展(zhan)(zhan)開(kai)(kai)面上的(de)(de)(de)當量漸(jian)(jian)開(kai)(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)來(lai)(lai)設 計，加(jia)工出來(lai)(lai)的(de)(de)(de)齒(chi)(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)(chi)形(xing)(xing)也(ye)只能在某一剖面中比較準(zhun)確，其它剖面則有一定誤差(cha)。因此(ci)直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)成 形(xing)(xing)銑刀適合粗加(jia)工和加(jia)工低精(jing)度的(de)(de)(de)直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)。
