成形齒輪(lun)銑刀銑齒法的加工原理

成(cheng)形(xing)(xing)齒(chi)(chi)(chi)輪(lun)銑(xian)(xian)刀(dao)(dao)加(jia)工(gong)(gong)直齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪(lun)屬于近(jin)(jin)似成(cheng)形(xing)(xing)法加(jia)工(gong)(gong)。因(yin)(yin)(yin)為直齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪(lun)的(de)傘形(xing)(xing)，理論上應為球面(mian)(mian)漸 開(kai)線。由(you)于球面(mian)(mian)不(bu)能展(zhan)開(kai)成(cheng)平面(mian)(mian)，所以是近(jin)(jin)似的(de)用背(bei)(bei)錐(zhui)展(zhan)開(kai)面(mian)(mian)上的(de)當量(liang)漸開(kai)線齒(chi)(chi)(chi)形(xing)(xing)來設(she)計成(cheng)形(xing)(xing)銑(xian)(xian)刀(dao)(dao)的(de) 齒(chi)(chi)(chi)形(xing)(xing)。由(you)于直齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪(lun)的(de)齒(chi)(chi)(chi)廓(kuo)是向(xiang)錐(zhui)頂收縮(suo)，因(yin)(yin)(yin)此(ci)沿節錐(zhui)母線上各背(bei)(bei)錐(zhui)展(zhan)開(kai)面(mian)(mian)上的(de)當量(liang)漸開(kai)線齒(chi)(chi)(chi)形(xing)(xing)曲 率不(bu)同。所以直齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪(lun)的(de)銑(xian)(xian)刀(dao)(dao)的(de)齒(chi)(chi)(chi)形(xing)(xing)只能按照節錐(zhui)母線上某一背(bei)(bei)錐(zhui)展(zhan)開(kai)面(mian)(mian)上的(de)當量(liang)漸開(kai)線齒(chi)(chi)(chi)形(xing)(xing)來設(she) 計，加(jia)工(gong)(gong)出來的(de)齒(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)形(xing)(xing)也只能在某一剖(pou)面(mian)(mian)中比較準確，其它剖(pou)面(mian)(mian)則有一定誤差(cha)。因(yin)(yin)(yin)此(ci)直齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪(lun)成(cheng) 形(xing)(xing)銑(xian)(xian)刀(dao)(dao)適(shi)合粗加(jia)工(gong)(gong)和(he)加(jia)工(gong)(gong)低精度的(de)直齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪(lun)。
