成形齒輪銑刀銑齒法的加工原理(li)

成形(xing)齒(chi)(chi)(chi)(chi)(chi)輪(lun)銑刀(dao)(dao)加(jia)工(gong)直(zhi)齒(chi)(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)(chi)輪(lun)屬于近似成形(xing)法加(jia)工(gong)。因為直(zhi)齒(chi)(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)(chi)輪(lun)的傘形(xing)，理論上(shang)(shang)應為球面(mian)漸 開線。由于球面(mian)不(bu)(bu)能(neng)展(zhan)開成平面(mian)，所(suo)以是近似的用背錐展(zhan)開面(mian)上(shang)(shang)的當量(liang)漸開線齒(chi)(chi)(chi)(chi)(chi)形(xing)來設計成形(xing)銑刀(dao)(dao)的 齒(chi)(chi)(chi)(chi)(chi)形(xing)。由于直(zhi)齒(chi)(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)(chi)輪(lun)的齒(chi)(chi)(chi)(chi)(chi)廓(kuo)是向錐頂收(shou)縮，因此沿節錐母線上(shang)(shang)各背錐展(zhan)開面(mian)上(shang)(shang)的當量(liang)漸開線齒(chi)(chi)(chi)(chi)(chi)形(xing)曲 率不(bu)(bu)同。所(suo)以直(zhi)齒(chi)(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)(chi)輪(lun)的銑刀(dao)(dao)的齒(chi)(chi)(chi)(chi)(chi)形(xing)只能(neng)按照節錐母線上(shang)(shang)某(mou)一(yi)背錐展(zhan)開面(mian)上(shang)(shang)的當量(liang)漸開線齒(chi)(chi)(chi)(chi)(chi)形(xing)來設 計，加(jia)工(gong)出來的齒(chi)(chi)(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)(chi)(chi)形(xing)也(ye)只能(neng)在某(mou)一(yi)剖面(mian)中比(bi)較準確(que)，其(qi)它剖面(mian)則有一(yi)定(ding)誤差。因此直(zhi)齒(chi)(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)(chi)輪(lun)成 形(xing)銑刀(dao)(dao)適合粗加(jia)工(gong)和加(jia)工(gong)低精度的直(zhi)齒(chi)(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)(chi)輪(lun)。
