成形齒輪銑刀銑齒法的(de)加工原理

成形(xing)(xing)齒(chi)(chi)(chi)輪銑(xian)刀(dao)加(jia)工(gong)(gong)直(zhi)(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪屬于(yu)近似成形(xing)(xing)法加(jia)工(gong)(gong)。因(yin)為直(zhi)(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪的傘形(xing)(xing)，理論上(shang)應(ying)為球(qiu)面(mian)(mian)漸(jian) 開(kai)線(xian)(xian)。由于(yu)球(qiu)面(mian)(mian)不能展(zhan)開(kai)成平面(mian)(mian)，所(suo)(suo)以是近似的用背(bei)錐(zhui)展(zhan)開(kai)面(mian)(mian)上(shang)的當量漸(jian)開(kai)線(xian)(xian)齒(chi)(chi)(chi)形(xing)(xing)來(lai)設計(ji)成形(xing)(xing)銑(xian)刀(dao)的 齒(chi)(chi)(chi)形(xing)(xing)。由于(yu)直(zhi)(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪的齒(chi)(chi)(chi)廓是向(xiang)錐(zhui)頂(ding)收縮(suo)，因(yin)此(ci)沿節(jie)錐(zhui)母線(xian)(xian)上(shang)各背(bei)錐(zhui)展(zhan)開(kai)面(mian)(mian)上(shang)的當量漸(jian)開(kai)線(xian)(xian)齒(chi)(chi)(chi)形(xing)(xing)曲 率(lv)不同。所(suo)(suo)以直(zhi)(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪的銑(xian)刀(dao)的齒(chi)(chi)(chi)形(xing)(xing)只能按照節(jie)錐(zhui)母線(xian)(xian)上(shang)某一背(bei)錐(zhui)展(zhan)開(kai)面(mian)(mian)上(shang)的當量漸(jian)開(kai)線(xian)(xian)齒(chi)(chi)(chi)形(xing)(xing)來(lai)設 計(ji)，加(jia)工(gong)(gong)出來(lai)的齒(chi)(chi)(chi)輪齒(chi)(chi)(chi)形(xing)(xing)也(ye)只能在某一剖面(mian)(mian)中比較(jiao)準確，其(qi)它剖面(mian)(mian)則有(you)一定誤差(cha)。因(yin)此(ci)直(zhi)(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪成 形(xing)(xing)銑(xian)刀(dao)適合粗加(jia)工(gong)(gong)和加(jia)工(gong)(gong)低精度的直(zhi)(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪。
