成(cheng)形齒輪銑刀(dao)銑齒法的加工原理

成(cheng)形(xing)(xing)齒(chi)(chi)(chi)(chi)(chi)輪銑刀(dao)(dao)加工(gong)直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪屬于(yu)近似成(cheng)形(xing)(xing)法加工(gong)。因為直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪的(de)(de)(de)(de)傘形(xing)(xing)，理論上應(ying)為球面(mian)(mian)漸(jian) 開(kai)(kai)線(xian)(xian)。由于(yu)球面(mian)(mian)不能展(zhan)開(kai)(kai)成(cheng)平面(mian)(mian)，所以是近似的(de)(de)(de)(de)用背錐(zhui)(zhui)(zhui)(zhui)展(zhan)開(kai)(kai)面(mian)(mian)上的(de)(de)(de)(de)當(dang)量(liang)漸(jian)開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)來設(she)計成(cheng)形(xing)(xing)銑刀(dao)(dao)的(de)(de)(de)(de) 齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)。由于(yu)直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪的(de)(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)廓是向錐(zhui)(zhui)(zhui)(zhui)頂收縮(suo)，因此(ci)沿節錐(zhui)(zhui)(zhui)(zhui)母線(xian)(xian)上各背錐(zhui)(zhui)(zhui)(zhui)展(zhan)開(kai)(kai)面(mian)(mian)上的(de)(de)(de)(de)當(dang)量(liang)漸(jian)開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)曲 率(lv)不同。所以直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪的(de)(de)(de)(de)銑刀(dao)(dao)的(de)(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)只(zhi)能按照節錐(zhui)(zhui)(zhui)(zhui)母線(xian)(xian)上某一(yi)背錐(zhui)(zhui)(zhui)(zhui)展(zhan)開(kai)(kai)面(mian)(mian)上的(de)(de)(de)(de)當(dang)量(liang)漸(jian)開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)來設(she) 計，加工(gong)出來的(de)(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)輪齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)也(ye)只(zhi)能在(zai)某一(yi)剖(pou)面(mian)(mian)中比較準確，其它剖(pou)面(mian)(mian)則有一(yi)定誤差。因此(ci)直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪成(cheng) 形(xing)(xing)銑刀(dao)(dao)適合粗加工(gong)和加工(gong)低精度的(de)(de)(de)(de)直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪。
