成形(xing)齒(chi)輪銑(xian)刀銑(xian)齒(chi)法的加工原理

成形齒(chi)(chi)(chi)輪銑刀(dao)(dao)加工(gong)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪屬于(yu)近似(si)成形法加工(gong)。因為(wei)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪的(de)傘形，理論上(shang)(shang)應為(wei)球面(mian)漸(jian) 開(kai)線。由(you)于(yu)球面(mian)不(bu)能(neng)(neng)展開(kai)成平面(mian)，所以是(shi)近似(si)的(de)用背(bei)錐(zhui)(zhui)展開(kai)面(mian)上(shang)(shang)的(de)當量(liang)(liang)漸(jian)開(kai)線齒(chi)(chi)(chi)形來設(she)計成形銑刀(dao)(dao)的(de) 齒(chi)(chi)(chi)形。由(you)于(yu)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪的(de)齒(chi)(chi)(chi)廓(kuo)是(shi)向(xiang)錐(zhui)(zhui)頂收縮，因此沿節(jie)錐(zhui)(zhui)母線上(shang)(shang)各(ge)背(bei)錐(zhui)(zhui)展開(kai)面(mian)上(shang)(shang)的(de)當量(liang)(liang)漸(jian)開(kai)線齒(chi)(chi)(chi)形曲 率(lv)不(bu)同。所以直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪的(de)銑刀(dao)(dao)的(de)齒(chi)(chi)(chi)形只(zhi)能(neng)(neng)按(an)照節(jie)錐(zhui)(zhui)母線上(shang)(shang)某一背(bei)錐(zhui)(zhui)展開(kai)面(mian)上(shang)(shang)的(de)當量(liang)(liang)漸(jian)開(kai)線齒(chi)(chi)(chi)形來設(she) 計，加工(gong)出來的(de)齒(chi)(chi)(chi)輪齒(chi)(chi)(chi)形也只(zhi)能(neng)(neng)在某一剖(pou)面(mian)中比較準確，其(qi)它剖(pou)面(mian)則有一定誤(wu)差(cha)。因此直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪成 形銑刀(dao)(dao)適合粗加工(gong)和加工(gong)低精度的(de)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪。
