成形齒輪銑刀銑齒法的加工原(yuan)理

成(cheng)(cheng)形齒(chi)輪(lun)銑(xian)刀加工直(zhi)齒(chi)錐(zhui)(zhui)齒(chi)輪(lun)屬于近似(si)成(cheng)(cheng)形法(fa)加工。因為直(zhi)齒(chi)錐(zhui)(zhui)齒(chi)輪(lun)的(de)傘形，理(li)論上(shang)應為球面(mian)(mian)(mian)漸(jian)(jian) 開(kai)線(xian)。由于球面(mian)(mian)(mian)不(bu)能展(zhan)開(kai)成(cheng)(cheng)平面(mian)(mian)(mian)，所以是(shi)(shi)近似(si)的(de)用背錐(zhui)(zhui)展(zhan)開(kai)面(mian)(mian)(mian)上(shang)的(de)當(dang)量漸(jian)(jian)開(kai)線(xian)齒(chi)形來(lai)設計成(cheng)(cheng)形銑(xian)刀的(de) 齒(chi)形。由于直(zhi)齒(chi)錐(zhui)(zhui)齒(chi)輪(lun)的(de)齒(chi)廓是(shi)(shi)向(xiang)錐(zhui)(zhui)頂(ding)收縮，因此沿節錐(zhui)(zhui)母(mu)線(xian)上(shang)各背錐(zhui)(zhui)展(zhan)開(kai)面(mian)(mian)(mian)上(shang)的(de)當(dang)量漸(jian)(jian)開(kai)線(xian)齒(chi)形曲 率不(bu)同(tong)。所以直(zhi)齒(chi)錐(zhui)(zhui)齒(chi)輪(lun)的(de)銑(xian)刀的(de)齒(chi)形只能按照(zhao)節錐(zhui)(zhui)母(mu)線(xian)上(shang)某(mou)一(yi)(yi)背錐(zhui)(zhui)展(zhan)開(kai)面(mian)(mian)(mian)上(shang)的(de)當(dang)量漸(jian)(jian)開(kai)線(xian)齒(chi)形來(lai)設 計，加工出來(lai)的(de)齒(chi)輪(lun)齒(chi)形也只能在某(mou)一(yi)(yi)剖面(mian)(mian)(mian)中(zhong)比較準確，其它剖面(mian)(mian)(mian)則(ze)有一(yi)(yi)定誤(wu)差。因此直(zhi)齒(chi)錐(zhui)(zhui)齒(chi)輪(lun)成(cheng)(cheng) 形銑(xian)刀適合粗加工和(he)加工低(di)精度的(de)直(zhi)齒(chi)錐(zhui)(zhui)齒(chi)輪(lun)。
