成形齒輪(lun)銑刀銑齒法的加工原理

成(cheng)形(xing)(xing)齒(chi)(chi)(chi)輪銑(xian)刀加工(gong)(gong)直(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪屬于近似成(cheng)形(xing)(xing)法加工(gong)(gong)。因(yin)為(wei)直(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪的(de)(de)傘形(xing)(xing)，理(li)論上(shang)(shang)應(ying)為(wei)球面(mian)漸(jian) 開(kai)線(xian)(xian)(xian)。由于球面(mian)不能(neng)展(zhan)開(kai)成(cheng)平面(mian)，所以是(shi)近似的(de)(de)用背(bei)(bei)錐(zhui)展(zhan)開(kai)面(mian)上(shang)(shang)的(de)(de)當(dang)量(liang)漸(jian)開(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)形(xing)(xing)來(lai)設計成(cheng)形(xing)(xing)銑(xian)刀的(de)(de) 齒(chi)(chi)(chi)形(xing)(xing)。由于直(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪的(de)(de)齒(chi)(chi)(chi)廓(kuo)是(shi)向(xiang)錐(zhui)頂收縮(suo)，因(yin)此沿(yan)節錐(zhui)母(mu)(mu)線(xian)(xian)(xian)上(shang)(shang)各背(bei)(bei)錐(zhui)展(zhan)開(kai)面(mian)上(shang)(shang)的(de)(de)當(dang)量(liang)漸(jian)開(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)形(xing)(xing)曲(qu) 率(lv)不同(tong)。所以直(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪的(de)(de)銑(xian)刀的(de)(de)齒(chi)(chi)(chi)形(xing)(xing)只能(neng)按照(zhao)節錐(zhui)母(mu)(mu)線(xian)(xian)(xian)上(shang)(shang)某一(yi)背(bei)(bei)錐(zhui)展(zhan)開(kai)面(mian)上(shang)(shang)的(de)(de)當(dang)量(liang)漸(jian)開(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)形(xing)(xing)來(lai)設 計，加工(gong)(gong)出來(lai)的(de)(de)齒(chi)(chi)(chi)輪齒(chi)(chi)(chi)形(xing)(xing)也只能(neng)在某一(yi)剖面(mian)中(zhong)比較(jiao)準(zhun)確(que)，其它剖面(mian)則有一(yi)定誤差。因(yin)此直(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪成(cheng) 形(xing)(xing)銑(xian)刀適合粗(cu)加工(gong)(gong)和加工(gong)(gong)低精度的(de)(de)直(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪。
