成形(xing)齒輪銑(xian)刀銑(xian)齒法的加工原理

成(cheng)(cheng)形(xing)(xing)齒(chi)(chi)(chi)輪(lun)(lun)(lun)銑(xian)刀加工直齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)屬于(yu)(yu)近似成(cheng)(cheng)形(xing)(xing)法(fa)加工。因(yin)為直齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)的(de)傘形(xing)(xing)，理(li)論上(shang)應為球(qiu)面(mian)(mian)漸 開(kai)(kai)線(xian)。由于(yu)(yu)球(qiu)面(mian)(mian)不能(neng)展(zhan)開(kai)(kai)成(cheng)(cheng)平面(mian)(mian)，所以是近似的(de)用背(bei)(bei)錐(zhui)(zhui)展(zhan)開(kai)(kai)面(mian)(mian)上(shang)的(de)當量(liang)漸開(kai)(kai)線(xian)齒(chi)(chi)(chi)形(xing)(xing)來設計成(cheng)(cheng)形(xing)(xing)銑(xian)刀的(de) 齒(chi)(chi)(chi)形(xing)(xing)。由于(yu)(yu)直齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)的(de)齒(chi)(chi)(chi)廓是向錐(zhui)(zhui)頂(ding)收縮，因(yin)此(ci)沿節錐(zhui)(zhui)母(mu)線(xian)上(shang)各背(bei)(bei)錐(zhui)(zhui)展(zhan)開(kai)(kai)面(mian)(mian)上(shang)的(de)當量(liang)漸開(kai)(kai)線(xian)齒(chi)(chi)(chi)形(xing)(xing)曲 率不同(tong)。所以直齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)的(de)銑(xian)刀的(de)齒(chi)(chi)(chi)形(xing)(xing)只(zhi)能(neng)按照節錐(zhui)(zhui)母(mu)線(xian)上(shang)某(mou)一(yi)(yi)背(bei)(bei)錐(zhui)(zhui)展(zhan)開(kai)(kai)面(mian)(mian)上(shang)的(de)當量(liang)漸開(kai)(kai)線(xian)齒(chi)(chi)(chi)形(xing)(xing)來設 計，加工出來的(de)齒(chi)(chi)(chi)輪(lun)(lun)(lun)齒(chi)(chi)(chi)形(xing)(xing)也只(zhi)能(neng)在某(mou)一(yi)(yi)剖面(mian)(mian)中比較(jiao)準確，其它剖面(mian)(mian)則有一(yi)(yi)定誤差(cha)。因(yin)此(ci)直齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)成(cheng)(cheng) 形(xing)(xing)銑(xian)刀適合(he)粗加工和加工低精度的(de)直齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)。
