成形齒輪銑刀(dao)銑齒法的加工原理

成(cheng)(cheng)形(xing)(xing)齒(chi)(chi)(chi)(chi)輪銑(xian)刀(dao)加工(gong)直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪屬于(yu)近(jin)(jin)似成(cheng)(cheng)形(xing)(xing)法加工(gong)。因(yin)為直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪的傘形(xing)(xing)，理論上(shang)應為球(qiu)面(mian)(mian)漸(jian) 開(kai)(kai)(kai)(kai)線。由于(yu)球(qiu)面(mian)(mian)不能展開(kai)(kai)(kai)(kai)成(cheng)(cheng)平(ping)面(mian)(mian)，所(suo)以是(shi)近(jin)(jin)似的用背錐(zhui)(zhui)(zhui)展開(kai)(kai)(kai)(kai)面(mian)(mian)上(shang)的當(dang)量漸(jian)開(kai)(kai)(kai)(kai)線齒(chi)(chi)(chi)(chi)形(xing)(xing)來(lai)設(she)計成(cheng)(cheng)形(xing)(xing)銑(xian)刀(dao)的 齒(chi)(chi)(chi)(chi)形(xing)(xing)。由于(yu)直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪的齒(chi)(chi)(chi)(chi)廓是(shi)向(xiang)錐(zhui)(zhui)(zhui)頂收(shou)縮，因(yin)此沿節(jie)錐(zhui)(zhui)(zhui)母線上(shang)各(ge)背錐(zhui)(zhui)(zhui)展開(kai)(kai)(kai)(kai)面(mian)(mian)上(shang)的當(dang)量漸(jian)開(kai)(kai)(kai)(kai)線齒(chi)(chi)(chi)(chi)形(xing)(xing)曲 率不同(tong)。所(suo)以直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪的銑(xian)刀(dao)的齒(chi)(chi)(chi)(chi)形(xing)(xing)只能按照節(jie)錐(zhui)(zhui)(zhui)母線上(shang)某一(yi)背錐(zhui)(zhui)(zhui)展開(kai)(kai)(kai)(kai)面(mian)(mian)上(shang)的當(dang)量漸(jian)開(kai)(kai)(kai)(kai)線齒(chi)(chi)(chi)(chi)形(xing)(xing)來(lai)設(she) 計，加工(gong)出(chu)來(lai)的齒(chi)(chi)(chi)(chi)輪齒(chi)(chi)(chi)(chi)形(xing)(xing)也只能在某一(yi)剖面(mian)(mian)中比較(jiao)準確，其它剖面(mian)(mian)則有一(yi)定(ding)誤(wu)差。因(yin)此直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪成(cheng)(cheng) 形(xing)(xing)銑(xian)刀(dao)適合粗加工(gong)和加工(gong)低精度的直(zhi)(zhi)(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪。
