成形齒輪銑刀銑齒法的(de)加工原理

成(cheng)形(xing)齒(chi)(chi)(chi)(chi)輪(lun)銑刀(dao)加(jia)工直(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)屬(shu)于近(jin)似成(cheng)形(xing)法(fa)加(jia)工。因(yin)為直(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)傘(san)形(xing)，理論(lun)上(shang)應為球面(mian)(mian)漸(jian) 開(kai)線(xian)(xian)。由于球面(mian)(mian)不能(neng)(neng)展開(kai)成(cheng)平面(mian)(mian)，所以是近(jin)似的(de)(de)用背錐(zhui)(zhui)(zhui)(zhui)展開(kai)面(mian)(mian)上(shang)的(de)(de)當(dang)(dang)量漸(jian)開(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)來設(she)計(ji)(ji)成(cheng)形(xing)銑刀(dao)的(de)(de) 齒(chi)(chi)(chi)(chi)形(xing)。由于直(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)齒(chi)(chi)(chi)(chi)廓是向錐(zhui)(zhui)(zhui)(zhui)頂(ding)收縮，因(yin)此沿節(jie)錐(zhui)(zhui)(zhui)(zhui)母線(xian)(xian)上(shang)各背錐(zhui)(zhui)(zhui)(zhui)展開(kai)面(mian)(mian)上(shang)的(de)(de)當(dang)(dang)量漸(jian)開(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)曲 率(lv)不同(tong)。所以直(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)銑刀(dao)的(de)(de)齒(chi)(chi)(chi)(chi)形(xing)只(zhi)能(neng)(neng)按照節(jie)錐(zhui)(zhui)(zhui)(zhui)母線(xian)(xian)上(shang)某一背錐(zhui)(zhui)(zhui)(zhui)展開(kai)面(mian)(mian)上(shang)的(de)(de)當(dang)(dang)量漸(jian)開(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)來設(she) 計(ji)(ji)，加(jia)工出來的(de)(de)齒(chi)(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)(chi)形(xing)也只(zhi)能(neng)(neng)在(zai)某一剖面(mian)(mian)中比較準確，其它剖面(mian)(mian)則有一定(ding)誤差。因(yin)此直(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)成(cheng) 形(xing)銑刀(dao)適合粗加(jia)工和(he)加(jia)工低(di)精(jing)度的(de)(de)直(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)。
