成形齒輪銑刀銑齒法的加工原理(li)

成(cheng)(cheng)(cheng)形(xing)齒(chi)(chi)輪銑(xian)刀(dao)加工(gong)直齒(chi)(chi)錐(zhui)齒(chi)(chi)輪屬(shu)于近似成(cheng)(cheng)(cheng)形(xing)法(fa)加工(gong)。因(yin)(yin)為直齒(chi)(chi)錐(zhui)齒(chi)(chi)輪的傘形(xing)，理論上(shang)應為球面漸(jian) 開(kai)(kai)線(xian)(xian)。由于球面不能(neng)(neng)展開(kai)(kai)成(cheng)(cheng)(cheng)平面，所以是近似的用背(bei)錐(zhui)展開(kai)(kai)面上(shang)的當(dang)(dang)量(liang)漸(jian)開(kai)(kai)線(xian)(xian)齒(chi)(chi)形(xing)來設計成(cheng)(cheng)(cheng)形(xing)銑(xian)刀(dao)的 齒(chi)(chi)形(xing)。由于直齒(chi)(chi)錐(zhui)齒(chi)(chi)輪的齒(chi)(chi)廓是向(xiang)錐(zhui)頂收縮，因(yin)(yin)此(ci)沿節錐(zhui)母(mu)線(xian)(xian)上(shang)各背(bei)錐(zhui)展開(kai)(kai)面上(shang)的當(dang)(dang)量(liang)漸(jian)開(kai)(kai)線(xian)(xian)齒(chi)(chi)形(xing)曲 率不同。所以直齒(chi)(chi)錐(zhui)齒(chi)(chi)輪的銑(xian)刀(dao)的齒(chi)(chi)形(xing)只能(neng)(neng)按照(zhao)節錐(zhui)母(mu)線(xian)(xian)上(shang)某一背(bei)錐(zhui)展開(kai)(kai)面上(shang)的當(dang)(dang)量(liang)漸(jian)開(kai)(kai)線(xian)(xian)齒(chi)(chi)形(xing)來設 計，加工(gong)出(chu)來的齒(chi)(chi)輪齒(chi)(chi)形(xing)也只能(neng)(neng)在某一剖(pou)面中(zhong)比(bi)較準確(que)，其它(ta)剖(pou)面則有一定誤差。因(yin)(yin)此(ci)直齒(chi)(chi)錐(zhui)齒(chi)(chi)輪成(cheng)(cheng)(cheng) 形(xing)銑(xian)刀(dao)適合粗加工(gong)和加工(gong)低(di)精度(du)的直齒(chi)(chi)錐(zhui)齒(chi)(chi)輪。
