成形(xing)齒輪銑刀(dao)銑齒法的加工原(yuan)理

成形齒輪(lun)(lun)銑刀加工(gong)直(zhi)齒錐(zhui)(zhui)齒輪(lun)(lun)屬于(yu)近似成形法加工(gong)。因(yin)為直(zhi)齒錐(zhui)(zhui)齒輪(lun)(lun)的(de)(de)(de)傘形，理論(lun)上應為球面(mian)(mian)(mian)(mian)漸(jian) 開線(xian)(xian)。由于(yu)球面(mian)(mian)(mian)(mian)不(bu)(bu)能(neng)(neng)展開成平面(mian)(mian)(mian)(mian)，所以是近似的(de)(de)(de)用(yong)背錐(zhui)(zhui)展開面(mian)(mian)(mian)(mian)上的(de)(de)(de)當(dang)量漸(jian)開線(xian)(xian)齒形來設(she)計(ji)成形銑刀的(de)(de)(de) 齒形。由于(yu)直(zhi)齒錐(zhui)(zhui)齒輪(lun)(lun)的(de)(de)(de)齒廓是向錐(zhui)(zhui)頂收(shou)縮，因(yin)此沿節(jie)錐(zhui)(zhui)母線(xian)(xian)上各背錐(zhui)(zhui)展開面(mian)(mian)(mian)(mian)上的(de)(de)(de)當(dang)量漸(jian)開線(xian)(xian)齒形曲 率不(bu)(bu)同。所以直(zhi)齒錐(zhui)(zhui)齒輪(lun)(lun)的(de)(de)(de)銑刀的(de)(de)(de)齒形只能(neng)(neng)按照節(jie)錐(zhui)(zhui)母線(xian)(xian)上某(mou)一(yi)背錐(zhui)(zhui)展開面(mian)(mian)(mian)(mian)上的(de)(de)(de)當(dang)量漸(jian)開線(xian)(xian)齒形來設(she) 計(ji)，加工(gong)出來的(de)(de)(de)齒輪(lun)(lun)齒形也只能(neng)(neng)在(zai)某(mou)一(yi)剖(pou)面(mian)(mian)(mian)(mian)中比較準確，其它剖(pou)面(mian)(mian)(mian)(mian)則有(you)一(yi)定誤差。因(yin)此直(zhi)齒錐(zhui)(zhui)齒輪(lun)(lun)成 形銑刀適(shi)合(he)粗加工(gong)和加工(gong)低精(jing)度的(de)(de)(de)直(zhi)齒錐(zhui)(zhui)齒輪(lun)(lun)。
