成形(xing)齒輪銑(xian)刀銑(xian)齒法的加(jia)工原理(li)

成(cheng)(cheng)形(xing)齒(chi)(chi)(chi)輪(lun)(lun)(lun)銑(xian)刀(dao)加工(gong)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)屬于近似成(cheng)(cheng)形(xing)法加工(gong)。因(yin)(yin)為(wei)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)的(de)傘形(xing)，理論上(shang)(shang)應為(wei)球面(mian)漸 開(kai)線(xian)(xian)(xian)。由于球面(mian)不能展(zhan)開(kai)成(cheng)(cheng)平面(mian)，所以(yi)是近似的(de)用背(bei)錐(zhui)(zhui)展(zhan)開(kai)面(mian)上(shang)(shang)的(de)當(dang)量(liang)漸開(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)形(xing)來(lai)設(she)計(ji)成(cheng)(cheng)形(xing)銑(xian)刀(dao)的(de) 齒(chi)(chi)(chi)形(xing)。由于直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)的(de)齒(chi)(chi)(chi)廓是向(xiang)錐(zhui)(zhui)頂收縮(suo)，因(yin)(yin)此沿節錐(zhui)(zhui)母(mu)線(xian)(xian)(xian)上(shang)(shang)各背(bei)錐(zhui)(zhui)展(zhan)開(kai)面(mian)上(shang)(shang)的(de)當(dang)量(liang)漸開(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)形(xing)曲 率不同。所以(yi)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)的(de)銑(xian)刀(dao)的(de)齒(chi)(chi)(chi)形(xing)只能按照節錐(zhui)(zhui)母(mu)線(xian)(xian)(xian)上(shang)(shang)某一背(bei)錐(zhui)(zhui)展(zhan)開(kai)面(mian)上(shang)(shang)的(de)當(dang)量(liang)漸開(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)形(xing)來(lai)設(she) 計(ji)，加工(gong)出(chu)來(lai)的(de)齒(chi)(chi)(chi)輪(lun)(lun)(lun)齒(chi)(chi)(chi)形(xing)也只能在某一剖面(mian)中比較準確(que)，其它(ta)剖面(mian)則有(you)一定誤差。因(yin)(yin)此直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)成(cheng)(cheng) 形(xing)銑(xian)刀(dao)適合粗加工(gong)和(he)加工(gong)低精度的(de)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)。
