成形齒輪(lun)銑刀(dao)銑齒法的加工原理

成(cheng)(cheng)形(xing)(xing)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)銑刀加(jia)工直(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)屬于近似成(cheng)(cheng)形(xing)(xing)法加(jia)工。因(yin)(yin)為(wei)直(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)的(de)(de)(de)傘(san)形(xing)(xing)，理論上(shang)(shang)(shang)應為(wei)球面(mian)(mian)漸(jian)(jian)(jian) 開(kai)線。由于球面(mian)(mian)不(bu)能展(zhan)開(kai)成(cheng)(cheng)平(ping)面(mian)(mian)，所以是(shi)近似的(de)(de)(de)用(yong)背錐(zhui)(zhui)(zhui)展(zhan)開(kai)面(mian)(mian)上(shang)(shang)(shang)的(de)(de)(de)當(dang)量(liang)(liang)(liang)漸(jian)(jian)(jian)開(kai)線齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)來(lai)(lai)設(she)計成(cheng)(cheng)形(xing)(xing)銑刀的(de)(de)(de) 齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)。由于直(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)的(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)廓是(shi)向錐(zhui)(zhui)(zhui)頂收縮，因(yin)(yin)此(ci)沿節錐(zhui)(zhui)(zhui)母線上(shang)(shang)(shang)各背錐(zhui)(zhui)(zhui)展(zhan)開(kai)面(mian)(mian)上(shang)(shang)(shang)的(de)(de)(de)當(dang)量(liang)(liang)(liang)漸(jian)(jian)(jian)開(kai)線齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)曲 率不(bu)同。所以直(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)的(de)(de)(de)銑刀的(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)只能按照節錐(zhui)(zhui)(zhui)母線上(shang)(shang)(shang)某一(yi)(yi)(yi)背錐(zhui)(zhui)(zhui)展(zhan)開(kai)面(mian)(mian)上(shang)(shang)(shang)的(de)(de)(de)當(dang)量(liang)(liang)(liang)漸(jian)(jian)(jian)開(kai)線齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)來(lai)(lai)設(she) 計，加(jia)工出(chu)來(lai)(lai)的(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)也(ye)只能在某一(yi)(yi)(yi)剖面(mian)(mian)中(zhong)比較準確，其(qi)它剖面(mian)(mian)則(ze)有一(yi)(yi)(yi)定誤差。因(yin)(yin)此(ci)直(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)成(cheng)(cheng) 形(xing)(xing)銑刀適合粗加(jia)工和加(jia)工低(di)精(jing)度的(de)(de)(de)直(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)。
