成形齒輪銑刀銑齒法的加工(gong)原理

成(cheng)形(xing)(xing)齒(chi)(chi)(chi)(chi)輪(lun)銑刀加(jia)工直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)屬于近(jin)(jin)似成(cheng)形(xing)(xing)法加(jia)工。因為直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)(de)傘形(xing)(xing)，理(li)論(lun)上應為球(qiu)面(mian)(mian)(mian)漸 開(kai)(kai)線(xian)(xian)。由(you)于球(qiu)面(mian)(mian)(mian)不(bu)能展開(kai)(kai)成(cheng)平面(mian)(mian)(mian)，所以是近(jin)(jin)似的(de)(de)(de)用背錐(zhui)展開(kai)(kai)面(mian)(mian)(mian)上的(de)(de)(de)當量(liang)(liang)漸開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)來(lai)設(she)計成(cheng)形(xing)(xing)銑刀的(de)(de)(de) 齒(chi)(chi)(chi)(chi)形(xing)(xing)。由(you)于直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)(de)齒(chi)(chi)(chi)(chi)廓是向錐(zhui)頂收縮(suo)，因此沿節(jie)錐(zhui)母線(xian)(xian)上各背錐(zhui)展開(kai)(kai)面(mian)(mian)(mian)上的(de)(de)(de)當量(liang)(liang)漸開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)曲 率(lv)不(bu)同(tong)。所以直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)(de)銑刀的(de)(de)(de)齒(chi)(chi)(chi)(chi)形(xing)(xing)只能按照節(jie)錐(zhui)母線(xian)(xian)上某一背錐(zhui)展開(kai)(kai)面(mian)(mian)(mian)上的(de)(de)(de)當量(liang)(liang)漸開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)來(lai)設(she) 計，加(jia)工出來(lai)的(de)(de)(de)齒(chi)(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)(chi)形(xing)(xing)也只能在(zai)某一剖面(mian)(mian)(mian)中比(bi)較準確(que)，其(qi)它剖面(mian)(mian)(mian)則(ze)有一定誤差。因此直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)成(cheng) 形(xing)(xing)銑刀適合(he)粗加(jia)工和加(jia)工低(di)精度(du)的(de)(de)(de)直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)。
