成形齒(chi)輪(lun)銑刀(dao)銑齒(chi)法(fa)的加(jia)工原理

成(cheng)形(xing)齒(chi)(chi)(chi)(chi)輪(lun)銑(xian)刀(dao)加工(gong)(gong)直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)屬(shu)于近似成(cheng)形(xing)法加工(gong)(gong)。因(yin)(yin)(yin)為(wei)直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)(de)傘形(xing)，理論(lun)上(shang)應為(wei)球(qiu)面漸 開線。由于球(qiu)面不能(neng)展(zhan)(zhan)開成(cheng)平面，所以是(shi)(shi)近似的(de)(de)(de)用背錐(zhui)展(zhan)(zhan)開面上(shang)的(de)(de)(de)當量漸開線齒(chi)(chi)(chi)(chi)形(xing)來(lai)設(she)(she)計成(cheng)形(xing)銑(xian)刀(dao)的(de)(de)(de) 齒(chi)(chi)(chi)(chi)形(xing)。由于直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)(de)齒(chi)(chi)(chi)(chi)廓是(shi)(shi)向錐(zhui)頂收(shou)縮，因(yin)(yin)(yin)此沿節錐(zhui)母(mu)線上(shang)各背錐(zhui)展(zhan)(zhan)開面上(shang)的(de)(de)(de)當量漸開線齒(chi)(chi)(chi)(chi)形(xing)曲 率不同(tong)。所以直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)(de)銑(xian)刀(dao)的(de)(de)(de)齒(chi)(chi)(chi)(chi)形(xing)只(zhi)能(neng)按照節錐(zhui)母(mu)線上(shang)某一背錐(zhui)展(zhan)(zhan)開面上(shang)的(de)(de)(de)當量漸開線齒(chi)(chi)(chi)(chi)形(xing)來(lai)設(she)(she) 計，加工(gong)(gong)出(chu)來(lai)的(de)(de)(de)齒(chi)(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)(chi)形(xing)也(ye)只(zhi)能(neng)在某一剖面中比較(jiao)準確，其(qi)它剖面則有一定誤差。因(yin)(yin)(yin)此直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)成(cheng) 形(xing)銑(xian)刀(dao)適合粗加工(gong)(gong)和加工(gong)(gong)低精度的(de)(de)(de)直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)。
