齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)面(mian)粗糙度(du)(du)差(cha)的原(yuan)因(yin)有(you)：機床、刀具(ju)或工(gong)(gong)(gong)件系(xi)(xi)統間(jian)隙大，整體剛(gang)度(du)(du)差(cha)；切(qie)割參數(shu)問(wen)題；工(gong)(gong)(gong)件和(he)滾(gun)(gun)刀位置變化；零(ling)件本身材料不均勻，滾(gun)(gun)刀磨削不當。通過以(yi)上描(miao)述，我們(men)對(dui)影響滾(gun)(gun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)精(jing)(jing)度(du)(du)的因(yin)素有(you)了一定的了解，特(te)別是(shi)(shi)各種誤差(cha)的原(yuan)因(yin)。結合以(yi)上問(wen)題，筆者認為，提高滾(gun)(gun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)加(jia)(jia)工(gong)(gong)(gong)精(jing)(jing)度(du)(du)可(ke)以(yi)從工(gong)(gong)(gong)藝系(xi)(xi)統精(jing)(jing)度(du)(du)、加(jia)(jia)工(gong)(gong)(gong)零(ling)件本身、加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)具(ju)、加(jia)(jia)工(gong)(gong)(gong)機床、加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝等方面(mian)進行(xing)控(kong)制，從而(er)提高滾(gun)(gun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)的加(jia)(jia)工(gong)(gong)(gong)精(jing)(jing)度(du)(du)。具(ju)體方法(fa)有(you)：提高齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)坯加(jia)(jia)工(gong)(gong)(gong)質(zhi)量：對(dui)于齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)加(jia)(jia)工(gong)(gong)(gong)，齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)坯的質(zhi)量直接影響齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)的精(jing)(jing)度(du)(du)。提高齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)坯質(zhi)量是(shi)(shi)提高齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)精(jing)(jing)度(du)(du)的基(ji)礎和(he)關鍵。齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)內孔和(he)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)端面(mian)是(shi)(shi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)加(jia)(jia)工(gong)(gong)(gong)的定位基(ji)準(zhun)。以(yi)往(wang)普通卡盤加(jia)(jia)工(gong)(gong)(gong)的齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)坯端面(mian)跳動(dong)≥0.05mm，而(er)精(jing)(jing)車夾具(ju)采用(yong)粘接增套技術，夾具(ju)精(jing)(jing)度(du)(du)可(ke)達0.005mm，加(jia)(jia)工(gong)(gong)(gong)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)坯精(jing)(jing)度(du)(du)≤0.015mm，提高定位基(ji)準(zhun)精(jing)(jing)度(du)(du)，可(ke)大大提高齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)加(jia)(jia)工(gong)(gong)(gong)精(jing)(jing)度(du)(du)，特(te)別是(shi)(shi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)向(xiang)精(jing)(jing)度(du)(du)。
