成形齒輪銑刀銑齒法的(de)加工原(yuan)理

成(cheng)(cheng)形(xing)(xing)(xing)齒(chi)(chi)(chi)輪銑(xian)(xian)刀(dao)加工(gong)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪屬于(yu)近似成(cheng)(cheng)形(xing)(xing)(xing)法加工(gong)。因(yin)為直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪的傘形(xing)(xing)(xing)，理(li)論上應為球面漸(jian) 開(kai)(kai)線(xian)(xian)。由于(yu)球面不能展(zhan)開(kai)(kai)成(cheng)(cheng)平面，所(suo)(suo)以(yi)(yi)是(shi)近似的用背(bei)錐(zhui)(zhui)(zhui)展(zhan)開(kai)(kai)面上的當量(liang)漸(jian)開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)形(xing)(xing)(xing)來(lai)設計(ji)成(cheng)(cheng)形(xing)(xing)(xing)銑(xian)(xian)刀(dao)的 齒(chi)(chi)(chi)形(xing)(xing)(xing)。由于(yu)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪的齒(chi)(chi)(chi)廓是(shi)向錐(zhui)(zhui)(zhui)頂收縮，因(yin)此沿(yan)節錐(zhui)(zhui)(zhui)母(mu)線(xian)(xian)上各背(bei)錐(zhui)(zhui)(zhui)展(zhan)開(kai)(kai)面上的當量(liang)漸(jian)開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)形(xing)(xing)(xing)曲 率不同。所(suo)(suo)以(yi)(yi)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪的銑(xian)(xian)刀(dao)的齒(chi)(chi)(chi)形(xing)(xing)(xing)只能按照節錐(zhui)(zhui)(zhui)母(mu)線(xian)(xian)上某(mou)一(yi)背(bei)錐(zhui)(zhui)(zhui)展(zhan)開(kai)(kai)面上的當量(liang)漸(jian)開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)形(xing)(xing)(xing)來(lai)設 計(ji)，加工(gong)出(chu)來(lai)的齒(chi)(chi)(chi)輪齒(chi)(chi)(chi)形(xing)(xing)(xing)也(ye)只能在某(mou)一(yi)剖(pou)面中(zhong)比較準確，其它剖(pou)面則有一(yi)定誤差。因(yin)此直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪成(cheng)(cheng) 形(xing)(xing)(xing)銑(xian)(xian)刀(dao)適合粗加工(gong)和加工(gong)低精(jing)度(du)的直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪。
