齒(chi)(chi)(chi)(chi)輪(lun)(lun)加(jia)(jia)工(gong)(gong)(gong)誤差與加(jia)(jia)工(gong)(gong)(gong)方法(fa)有關。齒(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)切削加(jia)(jia)工(gong)(gong)(gong)方法(fa)較(jiao)多，按照齒(chi)(chi)(chi)(chi)廓成(cheng)(cheng)(cheng)(cheng)形(xing)原理可分為(wei)仿 形(xing)法(fa)和展成(cheng)(cheng)(cheng)(cheng)法(fa)。仿形(xing)法(fa)是(shi)通(tong)過(guo)逐齒(chi)(chi)(chi)(chi)間斷分度(du)來完成(cheng)(cheng)(cheng)(cheng)整個齒(chi)(chi)(chi)(chi)輪(lun)(lun)齒(chi)(chi)(chi)(chi)圈(quan)的(de)(de)加(jia)(jia)工(gong)(gong)(gong)，而且切齒(chi)(chi)(chi)(chi)刀(dao)具(ju)的(de)(de)刀(dao) 刃形(xing)狀與被(bei)加(jia)(jia)工(gong)(gong)(gong)齒(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)漸開線(xian)(xian)齒(chi)(chi)(chi)(chi)廓相同，如(ru)(ru)用成(cheng)(cheng)(cheng)(cheng)形(xing)銑刀(dao)銑齒(chi)(chi)(chi)(chi)、成(cheng)(cheng)(cheng)(cheng)形(xing)磨齒(chi)(chi)(chi)(chi)等。屁(pi)成(cheng)(cheng)(cheng)(cheng)法(fa)是(shi)通(tong)過(guo)專用 齒(chi)(chi)(chi)(chi)輪(lun)(lun)加(jia)(jia)工(gong)(gong)(gong)機床的(de)(de)屁(pi)成(cheng)(cheng)(cheng)(cheng)運(yun)動形(xing)成(cheng)(cheng)(cheng)(cheng)漸開線(xian)(xian)齒(chi)(chi)(chi)(chi)面(mian)，如(ru)(ru)滾齒(chi)(chi)(chi)(chi)、插齒(chi)(chi)(chi)(chi)、磨齒(chi)(chi)(chi)(chi)、剃齒(chi)(chi)(chi)(chi)、沂齒(chi)(chi)(chi)(chi)、研齒(chi)(chi)(chi)(chi)等。齒(chi)(chi)(chi)(chi)輪(lun)(lun)加(jia)(jia)工(gong)(gong)(gong) 通(tong)常采用展成(cheng)(cheng)(cheng)(cheng)法(fa)。

    齒(chi)輪在加(jia)(jia)工(gong)(gong)過程中總是(shi)存在加(jia)(jia)工(gong)(gong)誤(wu)(wu)差。齒(chi)輪制(zhi)造(zao)誤(wu)(wu)差主要(yao)包(bao)括齒(chi)坯(pi)的制(zhi)造(zao)與(yu)安裝(zhuang)(zhuang)誤(wu)(wu)差t 安裝(zhuang)(zhuang)調整誤(wu)(wu)差、齒(chi)輪加(jia)(jia)工(gong)(gong)機(ji)床誤(wu)(wu)差、刀(dao)具的制(zhi)造(zao)與(yu)安裝(zhuang)(zhuang)誤(wu)(wu)差和夾具誤(wu)(wu)差等。各種(zhong)加(jia)(jia)工(gong)(gong)方法都有 多種(zhong)復(fu)雜(za)的工(gong)(gong)藝誤(wu)(wu)差因素，其誤(wu)(wu)差規(gui)律(lv)也不(bu)盡相同。以波齒(chi)加(jia)(jia)工(gong)(gong)為例(li)討論齒(chi) 輪加(jia)(jia)工(gong)(gong)誤(wu)(wu)差的主要(yao)來源。
