成形齒輪銑(xian)刀銑(xian)齒法的加工原理

成(cheng)形(xing)(xing)(xing)(xing)齒(chi)(chi)輪(lun)(lun)銑(xian)刀加工(gong)(gong)直(zhi)齒(chi)(chi)錐(zhui)齒(chi)(chi)輪(lun)(lun)屬于近(jin)似(si)成(cheng)形(xing)(xing)(xing)(xing)法加工(gong)(gong)。因為直(zhi)齒(chi)(chi)錐(zhui)齒(chi)(chi)輪(lun)(lun)的(de)(de)(de)傘形(xing)(xing)(xing)(xing)，理論上應為球面(mian)(mian)漸(jian) 開(kai)(kai)線(xian)。由于球面(mian)(mian)不能(neng)展開(kai)(kai)成(cheng)平面(mian)(mian)，所以(yi)是(shi)近(jin)似(si)的(de)(de)(de)用背(bei)錐(zhui)展開(kai)(kai)面(mian)(mian)上的(de)(de)(de)當量漸(jian)開(kai)(kai)線(xian)齒(chi)(chi)形(xing)(xing)(xing)(xing)來設計成(cheng)形(xing)(xing)(xing)(xing)銑(xian)刀的(de)(de)(de) 齒(chi)(chi)形(xing)(xing)(xing)(xing)。由于直(zhi)齒(chi)(chi)錐(zhui)齒(chi)(chi)輪(lun)(lun)的(de)(de)(de)齒(chi)(chi)廓(kuo)是(shi)向錐(zhui)頂收縮，因此沿節錐(zhui)母線(xian)上各背(bei)錐(zhui)展開(kai)(kai)面(mian)(mian)上的(de)(de)(de)當量漸(jian)開(kai)(kai)線(xian)齒(chi)(chi)形(xing)(xing)(xing)(xing)曲 率(lv)不同。所以(yi)直(zhi)齒(chi)(chi)錐(zhui)齒(chi)(chi)輪(lun)(lun)的(de)(de)(de)銑(xian)刀的(de)(de)(de)齒(chi)(chi)形(xing)(xing)(xing)(xing)只(zhi)(zhi)能(neng)按照節錐(zhui)母線(xian)上某(mou)一(yi)(yi)背(bei)錐(zhui)展開(kai)(kai)面(mian)(mian)上的(de)(de)(de)當量漸(jian)開(kai)(kai)線(xian)齒(chi)(chi)形(xing)(xing)(xing)(xing)來設 計，加工(gong)(gong)出來的(de)(de)(de)齒(chi)(chi)輪(lun)(lun)齒(chi)(chi)形(xing)(xing)(xing)(xing)也只(zhi)(zhi)能(neng)在某(mou)一(yi)(yi)剖面(mian)(mian)中比較(jiao)準確(que)，其它剖面(mian)(mian)則有一(yi)(yi)定誤差。因此直(zhi)齒(chi)(chi)錐(zhui)齒(chi)(chi)輪(lun)(lun)成(cheng) 形(xing)(xing)(xing)(xing)銑(xian)刀適合粗(cu)加工(gong)(gong)和加工(gong)(gong)低(di)精(jing)度的(de)(de)(de)直(zhi)齒(chi)(chi)錐(zhui)齒(chi)(chi)輪(lun)(lun)。
