成形(xing)齒輪銑刀銑齒法的加工原理

成(cheng)形(xing)齒(chi)(chi)(chi)(chi)輪(lun)銑(xian)刀(dao)加工(gong)直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)屬于(yu)近(jin)似成(cheng)形(xing)法加工(gong)。因為(wei)直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)傘形(xing)，理論上應(ying)為(wei)球面(mian)漸 開線。由于(yu)球面(mian)不能(neng)展開成(cheng)平(ping)面(mian)，所以是近(jin)似的(de)(de)用背錐(zhui)(zhui)(zhui)展開面(mian)上的(de)(de)當量漸開線齒(chi)(chi)(chi)(chi)形(xing)來(lai)設計成(cheng)形(xing)銑(xian)刀(dao)的(de)(de) 齒(chi)(chi)(chi)(chi)形(xing)。由于(yu)直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)齒(chi)(chi)(chi)(chi)廓是向錐(zhui)(zhui)(zhui)頂(ding)收縮，因此(ci)沿節錐(zhui)(zhui)(zhui)母(mu)線上各背錐(zhui)(zhui)(zhui)展開面(mian)上的(de)(de)當量漸開線齒(chi)(chi)(chi)(chi)形(xing)曲(qu) 率不同。所以直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)銑(xian)刀(dao)的(de)(de)齒(chi)(chi)(chi)(chi)形(xing)只能(neng)按照節錐(zhui)(zhui)(zhui)母(mu)線上某一(yi)背錐(zhui)(zhui)(zhui)展開面(mian)上的(de)(de)當量漸開線齒(chi)(chi)(chi)(chi)形(xing)來(lai)設 計，加工(gong)出來(lai)的(de)(de)齒(chi)(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)(chi)形(xing)也只能(neng)在某一(yi)剖面(mian)中比(bi)較準確，其它剖面(mian)則(ze)有一(yi)定誤差。因此(ci)直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)成(cheng) 形(xing)銑(xian)刀(dao)適合(he)粗加工(gong)和加工(gong)低精(jing)度的(de)(de)直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)。
