成形齒輪銑刀銑齒法的加工原理

成形(xing)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)銑刀(dao)加工(gong)(gong)(gong)直(zhi)(zhi)(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)屬于近似成形(xing)法加工(gong)(gong)(gong)。因為(wei)直(zhi)(zhi)(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)(de)傘形(xing)，理論上(shang)應為(wei)球面(mian)漸 開線(xian)。由于球面(mian)不能(neng)(neng)展開成平面(mian)，所以是(shi)近似的(de)(de)(de)用背錐(zhui)(zhui)(zhui)展開面(mian)上(shang)的(de)(de)(de)當(dang)(dang)量漸開線(xian)齒(chi)(chi)(chi)(chi)(chi)形(xing)來設計(ji)(ji)成形(xing)銑刀(dao)的(de)(de)(de) 齒(chi)(chi)(chi)(chi)(chi)形(xing)。由于直(zhi)(zhi)(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)廓是(shi)向錐(zhui)(zhui)(zhui)頂(ding)收縮，因此沿(yan)節錐(zhui)(zhui)(zhui)母線(xian)上(shang)各背錐(zhui)(zhui)(zhui)展開面(mian)上(shang)的(de)(de)(de)當(dang)(dang)量漸開線(xian)齒(chi)(chi)(chi)(chi)(chi)形(xing)曲 率不同。所以直(zhi)(zhi)(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)(de)銑刀(dao)的(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)形(xing)只能(neng)(neng)按照(zhao)節錐(zhui)(zhui)(zhui)母線(xian)上(shang)某一背錐(zhui)(zhui)(zhui)展開面(mian)上(shang)的(de)(de)(de)當(dang)(dang)量漸開線(xian)齒(chi)(chi)(chi)(chi)(chi)形(xing)來設 計(ji)(ji)，加工(gong)(gong)(gong)出來的(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)形(xing)也只能(neng)(neng)在(zai)某一剖面(mian)中比較準確，其它(ta)剖面(mian)則有一定誤差。因此直(zhi)(zhi)(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)成 形(xing)銑刀(dao)適合粗加工(gong)(gong)(gong)和加工(gong)(gong)(gong)低(di)精度(du)的(de)(de)(de)直(zhi)(zhi)(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)。
