成形齒輪銑刀(dao)銑齒法的加工原理

成形(xing)(xing)(xing)齒(chi)(chi)輪(lun)(lun)銑刀加(jia)(jia)工(gong)(gong)直齒(chi)(chi)錐(zhui)齒(chi)(chi)輪(lun)(lun)屬(shu)于近似成形(xing)(xing)(xing)法加(jia)(jia)工(gong)(gong)。因為直齒(chi)(chi)錐(zhui)齒(chi)(chi)輪(lun)(lun)的傘形(xing)(xing)(xing)，理論上(shang)(shang)應為球(qiu)面漸(jian) 開線(xian)。由于球(qiu)面不能展(zhan)開成平(ping)面，所(suo)以(yi)是近似的用背錐(zhui)展(zhan)開面上(shang)(shang)的當量(liang)漸(jian)開線(xian)齒(chi)(chi)形(xing)(xing)(xing)來(lai)(lai)設計成形(xing)(xing)(xing)銑刀的 齒(chi)(chi)形(xing)(xing)(xing)。由于直齒(chi)(chi)錐(zhui)齒(chi)(chi)輪(lun)(lun)的齒(chi)(chi)廓是向(xiang)錐(zhui)頂(ding)收縮，因此(ci)沿(yan)節錐(zhui)母線(xian)上(shang)(shang)各背錐(zhui)展(zhan)開面上(shang)(shang)的當量(liang)漸(jian)開線(xian)齒(chi)(chi)形(xing)(xing)(xing)曲(qu) 率不同(tong)。所(suo)以(yi)直齒(chi)(chi)錐(zhui)齒(chi)(chi)輪(lun)(lun)的銑刀的齒(chi)(chi)形(xing)(xing)(xing)只(zhi)能按照節錐(zhui)母線(xian)上(shang)(shang)某(mou)一背錐(zhui)展(zhan)開面上(shang)(shang)的當量(liang)漸(jian)開線(xian)齒(chi)(chi)形(xing)(xing)(xing)來(lai)(lai)設 計，加(jia)(jia)工(gong)(gong)出來(lai)(lai)的齒(chi)(chi)輪(lun)(lun)齒(chi)(chi)形(xing)(xing)(xing)也只(zhi)能在某(mou)一剖面中比較準(zhun)確，其它剖面則有一定(ding)誤差(cha)。因此(ci)直齒(chi)(chi)錐(zhui)齒(chi)(chi)輪(lun)(lun)成 形(xing)(xing)(xing)銑刀適(shi)合粗(cu)加(jia)(jia)工(gong)(gong)和加(jia)(jia)工(gong)(gong)低精度(du)的直齒(chi)(chi)錐(zhui)齒(chi)(chi)輪(lun)(lun)。
