成形(xing)齒輪銑刀銑齒法的(de)加工原理

成(cheng)形(xing)(xing)齒(chi)(chi)(chi)輪(lun)銑(xian)刀(dao)加工(gong)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)屬(shu)于(yu)(yu)近似(si)成(cheng)形(xing)(xing)法加工(gong)。因為直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)的(de)(de)傘(san)形(xing)(xing)，理論上應為球(qiu)面(mian)(mian)漸 開(kai)(kai)(kai)線(xian)。由于(yu)(yu)球(qiu)面(mian)(mian)不(bu)能展(zhan)開(kai)(kai)(kai)成(cheng)平(ping)面(mian)(mian)，所以(yi)是近似(si)的(de)(de)用背(bei)錐(zhui)(zhui)展(zhan)開(kai)(kai)(kai)面(mian)(mian)上的(de)(de)當(dang)量(liang)漸開(kai)(kai)(kai)線(xian)齒(chi)(chi)(chi)形(xing)(xing)來設計成(cheng)形(xing)(xing)銑(xian)刀(dao)的(de)(de) 齒(chi)(chi)(chi)形(xing)(xing)。由于(yu)(yu)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)的(de)(de)齒(chi)(chi)(chi)廓是向錐(zhui)(zhui)頂收縮，因此(ci)沿(yan)節錐(zhui)(zhui)母(mu)(mu)線(xian)上各(ge)背(bei)錐(zhui)(zhui)展(zhan)開(kai)(kai)(kai)面(mian)(mian)上的(de)(de)當(dang)量(liang)漸開(kai)(kai)(kai)線(xian)齒(chi)(chi)(chi)形(xing)(xing)曲 率(lv)不(bu)同。所以(yi)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)的(de)(de)銑(xian)刀(dao)的(de)(de)齒(chi)(chi)(chi)形(xing)(xing)只(zhi)能按照節錐(zhui)(zhui)母(mu)(mu)線(xian)上某一(yi)(yi)背(bei)錐(zhui)(zhui)展(zhan)開(kai)(kai)(kai)面(mian)(mian)上的(de)(de)當(dang)量(liang)漸開(kai)(kai)(kai)線(xian)齒(chi)(chi)(chi)形(xing)(xing)來設 計，加工(gong)出來的(de)(de)齒(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)形(xing)(xing)也只(zhi)能在某一(yi)(yi)剖面(mian)(mian)中比較準確，其它剖面(mian)(mian)則有一(yi)(yi)定(ding)誤差。因此(ci)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)成(cheng) 形(xing)(xing)銑(xian)刀(dao)適合粗加工(gong)和(he)加工(gong)低精(jing)度的(de)(de)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)。
