成形(xing)齒輪銑刀銑齒法的(de)加工原理

成形(xing)齒(chi)(chi)輪(lun)銑(xian)刀(dao)加(jia)工(gong)(gong)直(zhi)(zhi)齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)屬于近(jin)似成形(xing)法加(jia)工(gong)(gong)。因(yin)(yin)為(wei)直(zhi)(zhi)齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)的(de)(de)(de)傘形(xing)，理論上(shang)(shang)應為(wei)球面(mian)(mian)漸(jian)(jian) 開線(xian)。由(you)于球面(mian)(mian)不(bu)(bu)能(neng)展(zhan)開成平(ping)面(mian)(mian)，所以(yi)是近(jin)似的(de)(de)(de)用(yong)背(bei)(bei)錐(zhui)(zhui)展(zhan)開面(mian)(mian)上(shang)(shang)的(de)(de)(de)當量漸(jian)(jian)開線(xian)齒(chi)(chi)形(xing)來(lai)設(she)計成形(xing)銑(xian)刀(dao)的(de)(de)(de) 齒(chi)(chi)形(xing)。由(you)于直(zhi)(zhi)齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)的(de)(de)(de)齒(chi)(chi)廓是向錐(zhui)(zhui)頂收縮，因(yin)(yin)此沿節錐(zhui)(zhui)母(mu)線(xian)上(shang)(shang)各背(bei)(bei)錐(zhui)(zhui)展(zhan)開面(mian)(mian)上(shang)(shang)的(de)(de)(de)當量漸(jian)(jian)開線(xian)齒(chi)(chi)形(xing)曲 率(lv)不(bu)(bu)同。所以(yi)直(zhi)(zhi)齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)的(de)(de)(de)銑(xian)刀(dao)的(de)(de)(de)齒(chi)(chi)形(xing)只(zhi)(zhi)能(neng)按(an)照節錐(zhui)(zhui)母(mu)線(xian)上(shang)(shang)某一背(bei)(bei)錐(zhui)(zhui)展(zhan)開面(mian)(mian)上(shang)(shang)的(de)(de)(de)當量漸(jian)(jian)開線(xian)齒(chi)(chi)形(xing)來(lai)設(she) 計，加(jia)工(gong)(gong)出來(lai)的(de)(de)(de)齒(chi)(chi)輪(lun)齒(chi)(chi)形(xing)也只(zhi)(zhi)能(neng)在某一剖面(mian)(mian)中比較準確，其(qi)它剖面(mian)(mian)則有(you)一定誤差(cha)。因(yin)(yin)此直(zhi)(zhi)齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)成 形(xing)銑(xian)刀(dao)適合(he)粗加(jia)工(gong)(gong)和加(jia)工(gong)(gong)低精度的(de)(de)(de)直(zhi)(zhi)齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)。
