成(cheng)形齒(chi)輪(lun)銑刀銑齒(chi)法的加工原理

成(cheng)(cheng)(cheng)形(xing)齒(chi)(chi)(chi)輪(lun)銑刀加(jia)(jia)(jia)(jia)工(gong)(gong)直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪(lun)屬于近(jin)似成(cheng)(cheng)(cheng)形(xing)法加(jia)(jia)(jia)(jia)工(gong)(gong)。因為(wei)直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪(lun)的(de)傘(san)形(xing)，理論上應為(wei)球(qiu)面(mian)漸(jian)(jian) 開(kai)線。由于球(qiu)面(mian)不(bu)能展開(kai)成(cheng)(cheng)(cheng)平面(mian)，所(suo)以(yi)是(shi)(shi)近(jin)似的(de)用背(bei)錐(zhui)展開(kai)面(mian)上的(de)當量(liang)漸(jian)(jian)開(kai)線齒(chi)(chi)(chi)形(xing)來(lai)設(she)計(ji)成(cheng)(cheng)(cheng)形(xing)銑刀的(de) 齒(chi)(chi)(chi)形(xing)。由于直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪(lun)的(de)齒(chi)(chi)(chi)廓是(shi)(shi)向錐(zhui)頂收縮，因此沿(yan)節錐(zhui)母線上各背(bei)錐(zhui)展開(kai)面(mian)上的(de)當量(liang)漸(jian)(jian)開(kai)線齒(chi)(chi)(chi)形(xing)曲 率不(bu)同(tong)。所(suo)以(yi)直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪(lun)的(de)銑刀的(de)齒(chi)(chi)(chi)形(xing)只(zhi)(zhi)能按照節錐(zhui)母線上某一(yi)(yi)背(bei)錐(zhui)展開(kai)面(mian)上的(de)當量(liang)漸(jian)(jian)開(kai)線齒(chi)(chi)(chi)形(xing)來(lai)設(she) 計(ji)，加(jia)(jia)(jia)(jia)工(gong)(gong)出來(lai)的(de)齒(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)形(xing)也只(zhi)(zhi)能在某一(yi)(yi)剖面(mian)中(zhong)比較準確，其它剖面(mian)則有一(yi)(yi)定誤差。因此直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪(lun)成(cheng)(cheng)(cheng) 形(xing)銑刀適合粗(cu)加(jia)(jia)(jia)(jia)工(gong)(gong)和(he)加(jia)(jia)(jia)(jia)工(gong)(gong)低(di)精度的(de)直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪(lun)。
