成形齒輪銑刀銑齒法(fa)的加工原理(li)

成(cheng)形(xing)(xing)齒(chi)輪(lun)(lun)銑(xian)刀加(jia)工直齒(chi)錐(zhui)(zhui)(zhui)齒(chi)輪(lun)(lun)屬于近似成(cheng)形(xing)(xing)法加(jia)工。因(yin)為直齒(chi)錐(zhui)(zhui)(zhui)齒(chi)輪(lun)(lun)的(de)傘形(xing)(xing)，理論上(shang)(shang)(shang)(shang)應為球面漸 開線(xian)。由于球面不能展開成(cheng)平面，所(suo)以(yi)是近似的(de)用背錐(zhui)(zhui)(zhui)展開面上(shang)(shang)(shang)(shang)的(de)當量漸開線(xian)齒(chi)形(xing)(xing)來(lai)設計(ji)成(cheng)形(xing)(xing)銑(xian)刀的(de) 齒(chi)形(xing)(xing)。由于直齒(chi)錐(zhui)(zhui)(zhui)齒(chi)輪(lun)(lun)的(de)齒(chi)廓是向錐(zhui)(zhui)(zhui)頂收(shou)縮，因(yin)此沿節錐(zhui)(zhui)(zhui)母線(xian)上(shang)(shang)(shang)(shang)各背錐(zhui)(zhui)(zhui)展開面上(shang)(shang)(shang)(shang)的(de)當量漸開線(xian)齒(chi)形(xing)(xing)曲 率不同。所(suo)以(yi)直齒(chi)錐(zhui)(zhui)(zhui)齒(chi)輪(lun)(lun)的(de)銑(xian)刀的(de)齒(chi)形(xing)(xing)只能按照節錐(zhui)(zhui)(zhui)母線(xian)上(shang)(shang)(shang)(shang)某一(yi)背錐(zhui)(zhui)(zhui)展開面上(shang)(shang)(shang)(shang)的(de)當量漸開線(xian)齒(chi)形(xing)(xing)來(lai)設 計(ji)，加(jia)工出來(lai)的(de)齒(chi)輪(lun)(lun)齒(chi)形(xing)(xing)也只能在某一(yi)剖面中(zhong)比較準(zhun)確，其它剖面則(ze)有一(yi)定(ding)誤差。因(yin)此直齒(chi)錐(zhui)(zhui)(zhui)齒(chi)輪(lun)(lun)成(cheng) 形(xing)(xing)銑(xian)刀適(shi)合粗加(jia)工和加(jia)工低精(jing)度的(de)直齒(chi)錐(zhui)(zhui)(zhui)齒(chi)輪(lun)(lun)。
