成形齒輪銑刀(dao)銑齒法的加工原理(li)

成(cheng)(cheng)(cheng)形(xing)齒(chi)(chi)(chi)(chi)輪(lun)(lun)銑(xian)(xian)刀(dao)加(jia)工(gong)(gong)直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)屬于(yu)近似成(cheng)(cheng)(cheng)形(xing)法加(jia)工(gong)(gong)。因為(wei)直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)傘形(xing)，理論上(shang)應為(wei)球面(mian)漸 開(kai)(kai)線(xian)。由于(yu)球面(mian)不能(neng)(neng)(neng)展開(kai)(kai)成(cheng)(cheng)(cheng)平面(mian)，所(suo)以是近似的(de)用背錐(zhui)展開(kai)(kai)面(mian)上(shang)的(de)當量漸開(kai)(kai)線(xian)齒(chi)(chi)(chi)(chi)形(xing)來(lai)設計成(cheng)(cheng)(cheng)形(xing)銑(xian)(xian)刀(dao)的(de) 齒(chi)(chi)(chi)(chi)形(xing)。由于(yu)直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)齒(chi)(chi)(chi)(chi)廓(kuo)是向(xiang)錐(zhui)頂收縮，因此(ci)沿節錐(zhui)母線(xian)上(shang)各背錐(zhui)展開(kai)(kai)面(mian)上(shang)的(de)當量漸開(kai)(kai)線(xian)齒(chi)(chi)(chi)(chi)形(xing)曲 率不同(tong)。所(suo)以直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)銑(xian)(xian)刀(dao)的(de)齒(chi)(chi)(chi)(chi)形(xing)只(zhi)能(neng)(neng)(neng)按(an)照節錐(zhui)母線(xian)上(shang)某(mou)一(yi)背錐(zhui)展開(kai)(kai)面(mian)上(shang)的(de)當量漸開(kai)(kai)線(xian)齒(chi)(chi)(chi)(chi)形(xing)來(lai)設 計，加(jia)工(gong)(gong)出來(lai)的(de)齒(chi)(chi)(chi)(chi)輪(lun)(lun)齒(chi)(chi)(chi)(chi)形(xing)也只(zhi)能(neng)(neng)(neng)在某(mou)一(yi)剖面(mian)中(zhong)比較準確，其它剖面(mian)則有一(yi)定誤差。因此(ci)直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)成(cheng)(cheng)(cheng) 形(xing)銑(xian)(xian)刀(dao)適合粗加(jia)工(gong)(gong)和加(jia)工(gong)(gong)低精(jing)度的(de)直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)。
