成形齒輪銑刀(dao)銑齒法的加工原理(li)

成(cheng)形(xing)(xing)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)銑(xian)刀加工直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)屬于(yu)(yu)近似成(cheng)形(xing)(xing)法加工。因(yin)為直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)的(de)傘形(xing)(xing)，理論上(shang)(shang)(shang)應(ying)為球面(mian)(mian)(mian)漸(jian) 開(kai)(kai)線(xian)。由于(yu)(yu)球面(mian)(mian)(mian)不(bu)能(neng)(neng)展(zhan)開(kai)(kai)成(cheng)平面(mian)(mian)(mian)，所以是(shi)近似的(de)用背(bei)錐(zhui)(zhui)(zhui)展(zhan)開(kai)(kai)面(mian)(mian)(mian)上(shang)(shang)(shang)的(de)當(dang)量漸(jian)開(kai)(kai)線(xian)齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)(xing)來(lai)設計成(cheng)形(xing)(xing)銑(xian)刀的(de) 齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)(xing)。由于(yu)(yu)直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)的(de)齒(chi)(chi)(chi)(chi)(chi)(chi)廓是(shi)向錐(zhui)(zhui)(zhui)頂收縮(suo)，因(yin)此沿(yan)節(jie)錐(zhui)(zhui)(zhui)母線(xian)上(shang)(shang)(shang)各背(bei)錐(zhui)(zhui)(zhui)展(zhan)開(kai)(kai)面(mian)(mian)(mian)上(shang)(shang)(shang)的(de)當(dang)量漸(jian)開(kai)(kai)線(xian)齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)(xing)曲 率不(bu)同。所以直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)的(de)銑(xian)刀的(de)齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)(xing)只能(neng)(neng)按照節(jie)錐(zhui)(zhui)(zhui)母線(xian)上(shang)(shang)(shang)某一(yi)背(bei)錐(zhui)(zhui)(zhui)展(zhan)開(kai)(kai)面(mian)(mian)(mian)上(shang)(shang)(shang)的(de)當(dang)量漸(jian)開(kai)(kai)線(xian)齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)(xing)來(lai)設 計，加工出來(lai)的(de)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)(xing)也只能(neng)(neng)在某一(yi)剖面(mian)(mian)(mian)中比(bi)較準確，其它(ta)剖面(mian)(mian)(mian)則有(you)一(yi)定誤差。因(yin)此直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)成(cheng) 形(xing)(xing)銑(xian)刀適合粗(cu)加工和加工低精度的(de)直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)。
