成(cheng)形齒輪銑刀(dao)銑齒法(fa)的(de)加工原理

成(cheng)(cheng)形(xing)(xing)(xing)齒(chi)(chi)輪(lun)銑(xian)(xian)刀加工(gong)(gong)(gong)直齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)屬于(yu)近似(si)成(cheng)(cheng)形(xing)(xing)(xing)法加工(gong)(gong)(gong)。因為(wei)直齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)的(de)傘形(xing)(xing)(xing)，理論(lun)上(shang)應為(wei)球(qiu)(qiu)面(mian)(mian)漸(jian) 開線(xian)(xian)。由于(yu)球(qiu)(qiu)面(mian)(mian)不能(neng)展開成(cheng)(cheng)平面(mian)(mian)，所以是(shi)近似(si)的(de)用(yong)背(bei)(bei)錐(zhui)(zhui)展開面(mian)(mian)上(shang)的(de)當(dang)量(liang)漸(jian)開線(xian)(xian)齒(chi)(chi)形(xing)(xing)(xing)來(lai)設(she)計成(cheng)(cheng)形(xing)(xing)(xing)銑(xian)(xian)刀的(de) 齒(chi)(chi)形(xing)(xing)(xing)。由于(yu)直齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)的(de)齒(chi)(chi)廓是(shi)向錐(zhui)(zhui)頂收縮，因此沿節錐(zhui)(zhui)母(mu)線(xian)(xian)上(shang)各背(bei)(bei)錐(zhui)(zhui)展開面(mian)(mian)上(shang)的(de)當(dang)量(liang)漸(jian)開線(xian)(xian)齒(chi)(chi)形(xing)(xing)(xing)曲 率不同。所以直齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)的(de)銑(xian)(xian)刀的(de)齒(chi)(chi)形(xing)(xing)(xing)只能(neng)按照(zhao)節錐(zhui)(zhui)母(mu)線(xian)(xian)上(shang)某(mou)一(yi)(yi)背(bei)(bei)錐(zhui)(zhui)展開面(mian)(mian)上(shang)的(de)當(dang)量(liang)漸(jian)開線(xian)(xian)齒(chi)(chi)形(xing)(xing)(xing)來(lai)設(she) 計，加工(gong)(gong)(gong)出來(lai)的(de)齒(chi)(chi)輪(lun)齒(chi)(chi)形(xing)(xing)(xing)也(ye)只能(neng)在(zai)某(mou)一(yi)(yi)剖面(mian)(mian)中比較準(zhun)確，其它剖面(mian)(mian)則(ze)有一(yi)(yi)定誤差。因此直齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)成(cheng)(cheng) 形(xing)(xing)(xing)銑(xian)(xian)刀適合粗加工(gong)(gong)(gong)和加工(gong)(gong)(gong)低(di)精度(du)的(de)直齒(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)輪(lun)。
