成形齒輪銑刀銑齒法的加工(gong)原理

成(cheng)形(xing)(xing)(xing)齒(chi)(chi)(chi)(chi)輪(lun)銑(xian)刀(dao)(dao)加(jia)工直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)屬于近(jin)似成(cheng)形(xing)(xing)(xing)法加(jia)工。因(yin)為直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)傘形(xing)(xing)(xing)，理(li)論上(shang)(shang)應(ying)為球(qiu)面(mian)(mian)(mian)漸 開(kai)(kai)線(xian)(xian)。由于球(qiu)面(mian)(mian)(mian)不能展開(kai)(kai)成(cheng)平面(mian)(mian)(mian)，所(suo)以(yi)(yi)是近(jin)似的(de)用(yong)背錐(zhui)(zhui)(zhui)展開(kai)(kai)面(mian)(mian)(mian)上(shang)(shang)的(de)當量(liang)漸開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)來設(she)計成(cheng)形(xing)(xing)(xing)銑(xian)刀(dao)(dao)的(de) 齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)。由于直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)齒(chi)(chi)(chi)(chi)廓是向錐(zhui)(zhui)(zhui)頂收(shou)縮，因(yin)此沿節錐(zhui)(zhui)(zhui)母(mu)線(xian)(xian)上(shang)(shang)各背錐(zhui)(zhui)(zhui)展開(kai)(kai)面(mian)(mian)(mian)上(shang)(shang)的(de)當量(liang)漸開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)曲 率(lv)不同。所(suo)以(yi)(yi)直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)銑(xian)刀(dao)(dao)的(de)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)只能按照節錐(zhui)(zhui)(zhui)母(mu)線(xian)(xian)上(shang)(shang)某一(yi)(yi)背錐(zhui)(zhui)(zhui)展開(kai)(kai)面(mian)(mian)(mian)上(shang)(shang)的(de)當量(liang)漸開(kai)(kai)線(xian)(xian)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)來設(she) 計，加(jia)工出(chu)來的(de)齒(chi)(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)(chi)形(xing)(xing)(xing)也只能在某一(yi)(yi)剖(pou)面(mian)(mian)(mian)中(zhong)比(bi)較準確，其它(ta)剖(pou)面(mian)(mian)(mian)則有一(yi)(yi)定誤差。因(yin)此直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)成(cheng) 形(xing)(xing)(xing)銑(xian)刀(dao)(dao)適合粗(cu)加(jia)工和加(jia)工低(di)精(jing)度(du)的(de)直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)。
