成形齒輪銑刀銑齒法的加工原理

成(cheng)(cheng)形(xing)齒(chi)(chi)(chi)(chi)(chi)輪銑刀加工直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪屬于(yu)近(jin)似成(cheng)(cheng)形(xing)法(fa)加工。因(yin)為直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪的(de)傘形(xing)，理論上應為球(qiu)面(mian)(mian)(mian)漸(jian) 開(kai)(kai)線(xian)(xian)。由于(yu)球(qiu)面(mian)(mian)(mian)不能展開(kai)(kai)成(cheng)(cheng)平面(mian)(mian)(mian)，所以是近(jin)似的(de)用背(bei)錐(zhui)(zhui)(zhui)(zhui)(zhui)(zhui)展開(kai)(kai)面(mian)(mian)(mian)上的(de)當(dang)(dang)量(liang)漸(jian)開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)(chi)形(xing)來(lai)(lai)設計成(cheng)(cheng)形(xing)銑刀的(de) 齒(chi)(chi)(chi)(chi)(chi)形(xing)。由于(yu)直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪的(de)齒(chi)(chi)(chi)(chi)(chi)廓(kuo)是向錐(zhui)(zhui)(zhui)(zhui)(zhui)(zhui)頂收縮，因(yin)此沿(yan)節(jie)(jie)錐(zhui)(zhui)(zhui)(zhui)(zhui)(zhui)母線(xian)(xian)上各背(bei)錐(zhui)(zhui)(zhui)(zhui)(zhui)(zhui)展開(kai)(kai)面(mian)(mian)(mian)上的(de)當(dang)(dang)量(liang)漸(jian)開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)(chi)形(xing)曲 率不同。所以直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪的(de)銑刀的(de)齒(chi)(chi)(chi)(chi)(chi)形(xing)只(zhi)能按照節(jie)(jie)錐(zhui)(zhui)(zhui)(zhui)(zhui)(zhui)母線(xian)(xian)上某(mou)一背(bei)錐(zhui)(zhui)(zhui)(zhui)(zhui)(zhui)展開(kai)(kai)面(mian)(mian)(mian)上的(de)當(dang)(dang)量(liang)漸(jian)開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)(chi)形(xing)來(lai)(lai)設 計，加工出(chu)來(lai)(lai)的(de)齒(chi)(chi)(chi)(chi)(chi)輪齒(chi)(chi)(chi)(chi)(chi)形(xing)也只(zhi)能在(zai)某(mou)一剖面(mian)(mian)(mian)中比(bi)較準確，其它剖面(mian)(mian)(mian)則(ze)有一定誤差。因(yin)此直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪成(cheng)(cheng) 形(xing)銑刀適合粗加工和加工低(di)精度的(de)直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪。
