成形齒(chi)輪銑刀(dao)銑齒(chi)法的加工原理(li)

成形(xing)(xing)(xing)(xing)齒(chi)(chi)(chi)輪(lun)銑刀加工(gong)(gong)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)屬于(yu)近似成形(xing)(xing)(xing)(xing)法加工(gong)(gong)。因為直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)的(de)(de)傘形(xing)(xing)(xing)(xing)，理(li)論上(shang)(shang)應為球面(mian)漸 開(kai)(kai)(kai)(kai)線(xian)。由于(yu)球面(mian)不能展(zhan)開(kai)(kai)(kai)(kai)成平面(mian)，所以是(shi)近似的(de)(de)用背錐(zhui)(zhui)(zhui)(zhui)(zhui)展(zhan)開(kai)(kai)(kai)(kai)面(mian)上(shang)(shang)的(de)(de)當(dang)量(liang)漸開(kai)(kai)(kai)(kai)線(xian)齒(chi)(chi)(chi)形(xing)(xing)(xing)(xing)來(lai)設(she)計成形(xing)(xing)(xing)(xing)銑刀的(de)(de) 齒(chi)(chi)(chi)形(xing)(xing)(xing)(xing)。由于(yu)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)的(de)(de)齒(chi)(chi)(chi)廓(kuo)是(shi)向錐(zhui)(zhui)(zhui)(zhui)(zhui)頂收縮，因此(ci)沿節錐(zhui)(zhui)(zhui)(zhui)(zhui)母(mu)線(xian)上(shang)(shang)各背錐(zhui)(zhui)(zhui)(zhui)(zhui)展(zhan)開(kai)(kai)(kai)(kai)面(mian)上(shang)(shang)的(de)(de)當(dang)量(liang)漸開(kai)(kai)(kai)(kai)線(xian)齒(chi)(chi)(chi)形(xing)(xing)(xing)(xing)曲(qu) 率(lv)不同。所以直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)的(de)(de)銑刀的(de)(de)齒(chi)(chi)(chi)形(xing)(xing)(xing)(xing)只能按照節錐(zhui)(zhui)(zhui)(zhui)(zhui)母(mu)線(xian)上(shang)(shang)某(mou)(mou)一背錐(zhui)(zhui)(zhui)(zhui)(zhui)展(zhan)開(kai)(kai)(kai)(kai)面(mian)上(shang)(shang)的(de)(de)當(dang)量(liang)漸開(kai)(kai)(kai)(kai)線(xian)齒(chi)(chi)(chi)形(xing)(xing)(xing)(xing)來(lai)設(she) 計，加工(gong)(gong)出來(lai)的(de)(de)齒(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)形(xing)(xing)(xing)(xing)也只能在(zai)某(mou)(mou)一剖(pou)(pou)面(mian)中比較準確(que)，其(qi)它剖(pou)(pou)面(mian)則有一定誤差。因此(ci)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)成 形(xing)(xing)(xing)(xing)銑刀適合(he)粗加工(gong)(gong)和加工(gong)(gong)低(di)精(jing)度的(de)(de)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)。
