成形齒輪(lun)銑刀銑齒法的加工原理

成(cheng)形(xing)齒(chi)(chi)(chi)輪(lun)(lun)銑(xian)刀(dao)(dao)加工直齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)屬于(yu)近似(si)成(cheng)形(xing)法加工。因為直齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)的(de)傘形(xing)，理論(lun)上(shang)(shang)應為球面(mian)漸 開(kai)線(xian)(xian)(xian)(xian)(xian)。由于(yu)球面(mian)不能展開(kai)成(cheng)平(ping)面(mian)，所(suo)以是近似(si)的(de)用背(bei)錐(zhui)(zhui)(zhui)(zhui)展開(kai)面(mian)上(shang)(shang)的(de)當量漸開(kai)線(xian)(xian)(xian)(xian)(xian)齒(chi)(chi)(chi)形(xing)來(lai)設計(ji)成(cheng)形(xing)銑(xian)刀(dao)(dao)的(de) 齒(chi)(chi)(chi)形(xing)。由于(yu)直齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)的(de)齒(chi)(chi)(chi)廓是向錐(zhui)(zhui)(zhui)(zhui)頂收(shou)縮，因此沿節(jie)(jie)錐(zhui)(zhui)(zhui)(zhui)母(mu)線(xian)(xian)(xian)(xian)(xian)上(shang)(shang)各(ge)背(bei)錐(zhui)(zhui)(zhui)(zhui)展開(kai)面(mian)上(shang)(shang)的(de)當量漸開(kai)線(xian)(xian)(xian)(xian)(xian)齒(chi)(chi)(chi)形(xing)曲 率不同。所(suo)以直齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)的(de)銑(xian)刀(dao)(dao)的(de)齒(chi)(chi)(chi)形(xing)只能按照節(jie)(jie)錐(zhui)(zhui)(zhui)(zhui)母(mu)線(xian)(xian)(xian)(xian)(xian)上(shang)(shang)某一(yi)(yi)背(bei)錐(zhui)(zhui)(zhui)(zhui)展開(kai)面(mian)上(shang)(shang)的(de)當量漸開(kai)線(xian)(xian)(xian)(xian)(xian)齒(chi)(chi)(chi)形(xing)來(lai)設 計(ji)，加工出來(lai)的(de)齒(chi)(chi)(chi)輪(lun)(lun)齒(chi)(chi)(chi)形(xing)也只能在某一(yi)(yi)剖(pou)面(mian)中比較準確，其它(ta)剖(pou)面(mian)則有一(yi)(yi)定誤差(cha)。因此直齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)成(cheng) 形(xing)銑(xian)刀(dao)(dao)適合粗加工和加工低精度(du)的(de)直齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)。
