成形齒輪銑刀銑齒法的加工原(yuan)理

成形齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)銑(xian)刀加工(gong)直齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)屬于(yu)近似成形法加工(gong)。因(yin)(yin)為(wei)直齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)的(de)(de)傘形，理(li)論上(shang)應為(wei)球面(mian)(mian)(mian)漸(jian) 開(kai)(kai)線。由于(yu)球面(mian)(mian)(mian)不能展(zhan)開(kai)(kai)成平面(mian)(mian)(mian)，所以是近似的(de)(de)用背(bei)錐(zhui)展(zhan)開(kai)(kai)面(mian)(mian)(mian)上(shang)的(de)(de)當(dang)量(liang)漸(jian)開(kai)(kai)線齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)形來(lai)設(she)計(ji)成形銑(xian)刀的(de)(de) 齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)形。由于(yu)直齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)的(de)(de)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)廓是向錐(zhui)頂收縮，因(yin)(yin)此沿節(jie)錐(zhui)母(mu)線上(shang)各背(bei)錐(zhui)展(zhan)開(kai)(kai)面(mian)(mian)(mian)上(shang)的(de)(de)當(dang)量(liang)漸(jian)開(kai)(kai)線齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)形曲 率不同。所以直齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)的(de)(de)銑(xian)刀的(de)(de)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)形只能按(an)照節(jie)錐(zhui)母(mu)線上(shang)某一背(bei)錐(zhui)展(zhan)開(kai)(kai)面(mian)(mian)(mian)上(shang)的(de)(de)當(dang)量(liang)漸(jian)開(kai)(kai)線齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)形來(lai)設(she) 計(ji)，加工(gong)出來(lai)的(de)(de)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)形也只能在某一剖面(mian)(mian)(mian)中比(bi)較準確(que)，其它剖面(mian)(mian)(mian)則有一定誤差。因(yin)(yin)此直齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)成 形銑(xian)刀適(shi)合粗加工(gong)和加工(gong)低精度(du)的(de)(de)直齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)。
