成形齒輪銑刀銑齒法的(de)加工原理

成形(xing)齒(chi)(chi)(chi)輪銑刀(dao)加工(gong)直(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪屬(shu)于近似(si)(si)成形(xing)法加工(gong)。因為(wei)(wei)直(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪的(de)(de)(de)傘形(xing)，理論(lun)上(shang)(shang)(shang)應為(wei)(wei)球面(mian)(mian)漸(jian) 開(kai)線(xian)(xian)。由(you)于球面(mian)(mian)不能展開(kai)成平面(mian)(mian)，所以是近似(si)(si)的(de)(de)(de)用背(bei)(bei)錐(zhui)展開(kai)面(mian)(mian)上(shang)(shang)(shang)的(de)(de)(de)當量(liang)(liang)漸(jian)開(kai)線(xian)(xian)齒(chi)(chi)(chi)形(xing)來設計(ji)成形(xing)銑刀(dao)的(de)(de)(de) 齒(chi)(chi)(chi)形(xing)。由(you)于直(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪的(de)(de)(de)齒(chi)(chi)(chi)廓是向錐(zhui)頂收縮，因此沿節(jie)錐(zhui)母(mu)線(xian)(xian)上(shang)(shang)(shang)各(ge)背(bei)(bei)錐(zhui)展開(kai)面(mian)(mian)上(shang)(shang)(shang)的(de)(de)(de)當量(liang)(liang)漸(jian)開(kai)線(xian)(xian)齒(chi)(chi)(chi)形(xing)曲(qu) 率不同。所以直(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪的(de)(de)(de)銑刀(dao)的(de)(de)(de)齒(chi)(chi)(chi)形(xing)只(zhi)能按照節(jie)錐(zhui)母(mu)線(xian)(xian)上(shang)(shang)(shang)某一背(bei)(bei)錐(zhui)展開(kai)面(mian)(mian)上(shang)(shang)(shang)的(de)(de)(de)當量(liang)(liang)漸(jian)開(kai)線(xian)(xian)齒(chi)(chi)(chi)形(xing)來設 計(ji)，加工(gong)出來的(de)(de)(de)齒(chi)(chi)(chi)輪齒(chi)(chi)(chi)形(xing)也只(zhi)能在某一剖(pou)面(mian)(mian)中比較準確，其它剖(pou)面(mian)(mian)則有一定誤差。因此直(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪成 形(xing)銑刀(dao)適合粗加工(gong)和加工(gong)低精(jing)度(du)的(de)(de)(de)直(zhi)齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪。
