成形齒輪銑刀銑齒法的加工原理(li)

成形(xing)齒(chi)(chi)(chi)(chi)輪銑(xian)(xian)(xian)(xian)刀(dao)(dao)加工直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪屬于近似成形(xing)法加工。因(yin)為(wei)直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪的(de)(de)傘形(xing)，理論(lun)上(shang)(shang)應為(wei)球面(mian)漸 開線(xian)。由于球面(mian)不能展(zhan)(zhan)開成平面(mian)，所(suo)以是近似的(de)(de)用背(bei)(bei)錐(zhui)(zhui)(zhui)展(zhan)(zhan)開面(mian)上(shang)(shang)的(de)(de)當(dang)量(liang)漸開線(xian)齒(chi)(chi)(chi)(chi)形(xing)來(lai)設計成形(xing)銑(xian)(xian)(xian)(xian)刀(dao)(dao)的(de)(de) 齒(chi)(chi)(chi)(chi)形(xing)。由于直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪的(de)(de)齒(chi)(chi)(chi)(chi)廓是向(xiang)錐(zhui)(zhui)(zhui)頂收縮，因(yin)此(ci)沿節錐(zhui)(zhui)(zhui)母線(xian)上(shang)(shang)各(ge)背(bei)(bei)錐(zhui)(zhui)(zhui)展(zhan)(zhan)開面(mian)上(shang)(shang)的(de)(de)當(dang)量(liang)漸開線(xian)齒(chi)(chi)(chi)(chi)形(xing)曲 率(lv)不同。所(suo)以直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪的(de)(de)銑(xian)(xian)(xian)(xian)刀(dao)(dao)的(de)(de)齒(chi)(chi)(chi)(chi)形(xing)只(zhi)能按照(zhao)節錐(zhui)(zhui)(zhui)母線(xian)上(shang)(shang)某(mou)一背(bei)(bei)錐(zhui)(zhui)(zhui)展(zhan)(zhan)開面(mian)上(shang)(shang)的(de)(de)當(dang)量(liang)漸開線(xian)齒(chi)(chi)(chi)(chi)形(xing)來(lai)設 計，加工出來(lai)的(de)(de)齒(chi)(chi)(chi)(chi)輪齒(chi)(chi)(chi)(chi)形(xing)也只(zhi)能在某(mou)一剖面(mian)中(zhong)比較準確(que)，其它剖面(mian)則有(you)一定誤差。因(yin)此(ci)直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪成 形(xing)銑(xian)(xian)(xian)(xian)刀(dao)(dao)適合(he)粗加工和加工低(di)精(jing)度的(de)(de)直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪。
