成(cheng)形齒輪銑刀(dao)銑齒法的加工原(yuan)理

成(cheng)(cheng)形(xing)(xing)(xing)(xing)齒(chi)(chi)(chi)(chi)(chi)輪銑(xian)刀(dao)加工(gong)直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪屬于近似成(cheng)(cheng)形(xing)(xing)(xing)(xing)法加工(gong)。因(yin)為直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪的(de)(de)傘形(xing)(xing)(xing)(xing)，理論上(shang)應為球(qiu)面(mian)漸 開(kai)(kai)線(xian)(xian)(xian)。由于球(qiu)面(mian)不能展(zhan)開(kai)(kai)成(cheng)(cheng)平面(mian)，所以(yi)是(shi)近似的(de)(de)用背錐(zhui)展(zhan)開(kai)(kai)面(mian)上(shang)的(de)(de)當量漸開(kai)(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)(xing)(xing)來設計成(cheng)(cheng)形(xing)(xing)(xing)(xing)銑(xian)刀(dao)的(de)(de) 齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)(xing)(xing)。由于直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪的(de)(de)齒(chi)(chi)(chi)(chi)(chi)廓是(shi)向錐(zhui)頂收縮，因(yin)此沿節錐(zhui)母線(xian)(xian)(xian)上(shang)各背錐(zhui)展(zhan)開(kai)(kai)面(mian)上(shang)的(de)(de)當量漸開(kai)(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)(xing)(xing)曲 率不同。所以(yi)直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪的(de)(de)銑(xian)刀(dao)的(de)(de)齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)(xing)(xing)只(zhi)能按照節錐(zhui)母線(xian)(xian)(xian)上(shang)某(mou)一背錐(zhui)展(zhan)開(kai)(kai)面(mian)上(shang)的(de)(de)當量漸開(kai)(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)(xing)(xing)來設 計，加工(gong)出(chu)來的(de)(de)齒(chi)(chi)(chi)(chi)(chi)輪齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)(xing)(xing)也只(zhi)能在某(mou)一剖(pou)面(mian)中比較準確，其它剖(pou)面(mian)則有一定誤差。因(yin)此直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪成(cheng)(cheng) 形(xing)(xing)(xing)(xing)銑(xian)刀(dao)適合粗(cu)加工(gong)和加工(gong)低精度的(de)(de)直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪。
