成形齒輪銑刀銑齒法的加工原理

成(cheng)形(xing)(xing)(xing)(xing)齒(chi)(chi)(chi)輪(lun)(lun)銑刀(dao)加(jia)工(gong)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)屬于近似成(cheng)形(xing)(xing)(xing)(xing)法加(jia)工(gong)。因(yin)(yin)為直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)的(de)(de)傘形(xing)(xing)(xing)(xing)，理論上應為球(qiu)(qiu)面(mian)漸(jian)(jian) 開(kai)線(xian)(xian)(xian)。由于球(qiu)(qiu)面(mian)不能展開(kai)成(cheng)平面(mian)，所以(yi)是近似的(de)(de)用背錐(zhui)(zhui)(zhui)展開(kai)面(mian)上的(de)(de)當量(liang)(liang)漸(jian)(jian)開(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)形(xing)(xing)(xing)(xing)來(lai)設計(ji)成(cheng)形(xing)(xing)(xing)(xing)銑刀(dao)的(de)(de) 齒(chi)(chi)(chi)形(xing)(xing)(xing)(xing)。由于直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)的(de)(de)齒(chi)(chi)(chi)廓是向錐(zhui)(zhui)(zhui)頂收縮，因(yin)(yin)此(ci)(ci)沿節(jie)(jie)錐(zhui)(zhui)(zhui)母線(xian)(xian)(xian)上各背錐(zhui)(zhui)(zhui)展開(kai)面(mian)上的(de)(de)當量(liang)(liang)漸(jian)(jian)開(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)形(xing)(xing)(xing)(xing)曲 率不同。所以(yi)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)的(de)(de)銑刀(dao)的(de)(de)齒(chi)(chi)(chi)形(xing)(xing)(xing)(xing)只能按照節(jie)(jie)錐(zhui)(zhui)(zhui)母線(xian)(xian)(xian)上某一背錐(zhui)(zhui)(zhui)展開(kai)面(mian)上的(de)(de)當量(liang)(liang)漸(jian)(jian)開(kai)線(xian)(xian)(xian)齒(chi)(chi)(chi)形(xing)(xing)(xing)(xing)來(lai)設 計(ji)，加(jia)工(gong)出來(lai)的(de)(de)齒(chi)(chi)(chi)輪(lun)(lun)齒(chi)(chi)(chi)形(xing)(xing)(xing)(xing)也只能在某一剖面(mian)中(zhong)比(bi)較(jiao)準確，其它剖面(mian)則有一定誤差。因(yin)(yin)此(ci)(ci)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)成(cheng) 形(xing)(xing)(xing)(xing)銑刀(dao)適(shi)合粗加(jia)工(gong)和加(jia)工(gong)低精度的(de)(de)直(zhi)齒(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)輪(lun)(lun)。
