成(cheng)形齒輪銑刀銑齒法的加(jia)工原理

成形(xing)(xing)(xing)齒(chi)(chi)(chi)(chi)輪(lun)(lun)銑(xian)刀(dao)加(jia)工直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)屬(shu)于(yu)近似(si)成形(xing)(xing)(xing)法(fa)加(jia)工。因(yin)為(wei)直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)傘形(xing)(xing)(xing)，理論上(shang)應(ying)為(wei)球面(mian)(mian)漸 開(kai)(kai)線(xian)(xian)(xian)。由于(yu)球面(mian)(mian)不能(neng)(neng)展(zhan)開(kai)(kai)成平面(mian)(mian)，所(suo)以是近似(si)的(de)用背錐(zhui)(zhui)(zhui)(zhui)展(zhan)開(kai)(kai)面(mian)(mian)上(shang)的(de)當量漸開(kai)(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)來設計(ji)成形(xing)(xing)(xing)銑(xian)刀(dao)的(de) 齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)。由于(yu)直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)齒(chi)(chi)(chi)(chi)廓是向(xiang)錐(zhui)(zhui)(zhui)(zhui)頂收縮，因(yin)此(ci)(ci)沿節錐(zhui)(zhui)(zhui)(zhui)母線(xian)(xian)(xian)上(shang)各背錐(zhui)(zhui)(zhui)(zhui)展(zhan)開(kai)(kai)面(mian)(mian)上(shang)的(de)當量漸開(kai)(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)曲(qu) 率不同(tong)。所(suo)以直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)銑(xian)刀(dao)的(de)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)只能(neng)(neng)按照節錐(zhui)(zhui)(zhui)(zhui)母線(xian)(xian)(xian)上(shang)某一背錐(zhui)(zhui)(zhui)(zhui)展(zhan)開(kai)(kai)面(mian)(mian)上(shang)的(de)當量漸開(kai)(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)來設 計(ji)，加(jia)工出來的(de)齒(chi)(chi)(chi)(chi)輪(lun)(lun)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)也只能(neng)(neng)在(zai)某一剖面(mian)(mian)中比(bi)較準確，其它剖面(mian)(mian)則有(you)一定誤差(cha)。因(yin)此(ci)(ci)直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)成 形(xing)(xing)(xing)銑(xian)刀(dao)適合(he)粗加(jia)工和加(jia)工低精度的(de)直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)。
