成(cheng)形齒(chi)輪銑刀銑齒(chi)法的加(jia)工(gong)原理

成形(xing)(xing)(xing)齒(chi)(chi)(chi)(chi)輪(lun)銑(xian)刀加工(gong)直(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)輪(lun)屬于近似成形(xing)(xing)(xing)法(fa)加工(gong)。因為直(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)傘形(xing)(xing)(xing)，理論上(shang)應為球(qiu)面(mian)(mian)(mian)漸 開(kai)(kai)線。由于球(qiu)面(mian)(mian)(mian)不能展(zhan)(zhan)開(kai)(kai)成平面(mian)(mian)(mian)，所(suo)(suo)以(yi)是(shi)(shi)近似的(de)(de)用背(bei)錐展(zhan)(zhan)開(kai)(kai)面(mian)(mian)(mian)上(shang)的(de)(de)當量(liang)漸開(kai)(kai)線齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)來設計(ji)成形(xing)(xing)(xing)銑(xian)刀的(de)(de) 齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)。由于直(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)齒(chi)(chi)(chi)(chi)廓是(shi)(shi)向(xiang)錐頂收(shou)縮(suo)，因此(ci)沿節錐母(mu)(mu)線上(shang)各背(bei)錐展(zhan)(zhan)開(kai)(kai)面(mian)(mian)(mian)上(shang)的(de)(de)當量(liang)漸開(kai)(kai)線齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)曲 率不同。所(suo)(suo)以(yi)直(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)銑(xian)刀的(de)(de)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)只能按照節錐母(mu)(mu)線上(shang)某(mou)一背(bei)錐展(zhan)(zhan)開(kai)(kai)面(mian)(mian)(mian)上(shang)的(de)(de)當量(liang)漸開(kai)(kai)線齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)來設 計(ji)，加工(gong)出來的(de)(de)齒(chi)(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)也只能在某(mou)一剖面(mian)(mian)(mian)中比較準確(que)，其它(ta)剖面(mian)(mian)(mian)則有一定誤(wu)差。因此(ci)直(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)輪(lun)成 形(xing)(xing)(xing)銑(xian)刀適合粗加工(gong)和加工(gong)低(di)精度的(de)(de)直(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)輪(lun)。
