成形齒輪銑刀銑齒法的加工原理

成形(xing)(xing)齒(chi)(chi)(chi)(chi)輪銑刀加工(gong)直齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪屬(shu)于近似(si)成形(xing)(xing)法加工(gong)。因為直齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪的(de)(de)(de)傘(san)形(xing)(xing)，理論(lun)上(shang)應為球面(mian)(mian)(mian)(mian)漸(jian) 開(kai)(kai)(kai)(kai)線(xian)(xian)(xian)。由于球面(mian)(mian)(mian)(mian)不能(neng)展(zhan)(zhan)(zhan)開(kai)(kai)(kai)(kai)成平面(mian)(mian)(mian)(mian)，所以(yi)是近似(si)的(de)(de)(de)用(yong)背錐(zhui)(zhui)展(zhan)(zhan)(zhan)開(kai)(kai)(kai)(kai)面(mian)(mian)(mian)(mian)上(shang)的(de)(de)(de)當(dang)量漸(jian)開(kai)(kai)(kai)(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)來設計(ji)成形(xing)(xing)銑刀的(de)(de)(de) 齒(chi)(chi)(chi)(chi)形(xing)(xing)。由于直齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪的(de)(de)(de)齒(chi)(chi)(chi)(chi)廓是向錐(zhui)(zhui)頂收縮，因此沿節(jie)錐(zhui)(zhui)母線(xian)(xian)(xian)上(shang)各背錐(zhui)(zhui)展(zhan)(zhan)(zhan)開(kai)(kai)(kai)(kai)面(mian)(mian)(mian)(mian)上(shang)的(de)(de)(de)當(dang)量漸(jian)開(kai)(kai)(kai)(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)曲(qu) 率不同。所以(yi)直齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪的(de)(de)(de)銑刀的(de)(de)(de)齒(chi)(chi)(chi)(chi)形(xing)(xing)只能(neng)按照節(jie)錐(zhui)(zhui)母線(xian)(xian)(xian)上(shang)某(mou)(mou)一(yi)背錐(zhui)(zhui)展(zhan)(zhan)(zhan)開(kai)(kai)(kai)(kai)面(mian)(mian)(mian)(mian)上(shang)的(de)(de)(de)當(dang)量漸(jian)開(kai)(kai)(kai)(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)來設 計(ji)，加工(gong)出來的(de)(de)(de)齒(chi)(chi)(chi)(chi)輪齒(chi)(chi)(chi)(chi)形(xing)(xing)也只能(neng)在某(mou)(mou)一(yi)剖面(mian)(mian)(mian)(mian)中比較準確，其它剖面(mian)(mian)(mian)(mian)則有一(yi)定(ding)誤差。因此直齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪成 形(xing)(xing)銑刀適合(he)粗加工(gong)和加工(gong)低精度的(de)(de)(de)直齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪。
