成形(xing)齒輪銑刀(dao)銑齒法的加工原(yuan)理

成形(xing)(xing)(xing)齒(chi)(chi)輪(lun)(lun)(lun)銑刀加工(gong)(gong)(gong)直(zhi)(zhi)齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)(lun)(lun)屬(shu)于近似(si)成形(xing)(xing)(xing)法(fa)加工(gong)(gong)(gong)。因(yin)為(wei)直(zhi)(zhi)齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)(lun)(lun)的(de)傘(san)形(xing)(xing)(xing)，理論上(shang)應為(wei)球(qiu)面(mian)漸 開(kai)(kai)(kai)線(xian)(xian)(xian)。由于球(qiu)面(mian)不能(neng)展開(kai)(kai)(kai)成平面(mian)，所以(yi)是近似(si)的(de)用背錐(zhui)(zhui)展開(kai)(kai)(kai)面(mian)上(shang)的(de)當量漸開(kai)(kai)(kai)線(xian)(xian)(xian)齒(chi)(chi)形(xing)(xing)(xing)來設計成形(xing)(xing)(xing)銑刀的(de) 齒(chi)(chi)形(xing)(xing)(xing)。由于直(zhi)(zhi)齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)(lun)(lun)的(de)齒(chi)(chi)廓是向(xiang)錐(zhui)(zhui)頂收縮，因(yin)此沿節(jie)錐(zhui)(zhui)母線(xian)(xian)(xian)上(shang)各(ge)背錐(zhui)(zhui)展開(kai)(kai)(kai)面(mian)上(shang)的(de)當量漸開(kai)(kai)(kai)線(xian)(xian)(xian)齒(chi)(chi)形(xing)(xing)(xing)曲 率不同(tong)。所以(yi)直(zhi)(zhi)齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)(lun)(lun)的(de)銑刀的(de)齒(chi)(chi)形(xing)(xing)(xing)只(zhi)能(neng)按照節(jie)錐(zhui)(zhui)母線(xian)(xian)(xian)上(shang)某一(yi)(yi)背錐(zhui)(zhui)展開(kai)(kai)(kai)面(mian)上(shang)的(de)當量漸開(kai)(kai)(kai)線(xian)(xian)(xian)齒(chi)(chi)形(xing)(xing)(xing)來設 計，加工(gong)(gong)(gong)出(chu)來的(de)齒(chi)(chi)輪(lun)(lun)(lun)齒(chi)(chi)形(xing)(xing)(xing)也只(zhi)能(neng)在某一(yi)(yi)剖面(mian)中比較準確(que)，其它剖面(mian)則有一(yi)(yi)定(ding)誤差。因(yin)此直(zhi)(zhi)齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)(lun)(lun)成 形(xing)(xing)(xing)銑刀適合粗加工(gong)(gong)(gong)和加工(gong)(gong)(gong)低(di)精(jing)度的(de)直(zhi)(zhi)齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)(lun)(lun)。
