成(cheng)形齒輪銑刀銑齒法的(de)加工原理(li)

成形(xing)(xing)(xing)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)銑刀(dao)加工直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)屬(shu)于(yu)近(jin)似成形(xing)(xing)(xing)法加工。因(yin)為直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)傘形(xing)(xing)(xing)，理論(lun)上(shang)(shang)應為球面(mian)(mian)漸(jian) 開(kai)線。由于(yu)球面(mian)(mian)不能(neng)展開(kai)成平面(mian)(mian)，所(suo)以(yi)是近(jin)似的(de)(de)用背錐(zhui)(zhui)展開(kai)面(mian)(mian)上(shang)(shang)的(de)(de)當(dang)量(liang)(liang)漸(jian)開(kai)線齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)(xing)來設計成形(xing)(xing)(xing)銑刀(dao)的(de)(de) 齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)(xing)。由于(yu)直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)齒(chi)(chi)(chi)(chi)(chi)廓(kuo)是向錐(zhui)(zhui)頂收(shou)縮，因(yin)此沿節(jie)錐(zhui)(zhui)母(mu)線上(shang)(shang)各背錐(zhui)(zhui)展開(kai)面(mian)(mian)上(shang)(shang)的(de)(de)當(dang)量(liang)(liang)漸(jian)開(kai)線齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)(xing)曲 率不同。所(suo)以(yi)直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)銑刀(dao)的(de)(de)齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)(xing)只(zhi)能(neng)按照(zhao)節(jie)錐(zhui)(zhui)母(mu)線上(shang)(shang)某一背錐(zhui)(zhui)展開(kai)面(mian)(mian)上(shang)(shang)的(de)(de)當(dang)量(liang)(liang)漸(jian)開(kai)線齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)(xing)來設 計，加工出來的(de)(de)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)(xing)也只(zhi)能(neng)在(zai)某一剖面(mian)(mian)中比較準確，其它剖面(mian)(mian)則(ze)有一定(ding)誤(wu)差。因(yin)此直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)成 形(xing)(xing)(xing)銑刀(dao)適合粗加工和加工低精度的(de)(de)直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)。
