公法線長度誤(wu)差(cha):滾(gun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)采用(yong)展成(cheng)法原理(li)進行齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)加工(gong)(gong)。刀(dao)具與(yu)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)坯之(zhi)(zhi)間的分齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)傳動鏈(lian)需要有一定的傳動比，以保證齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)運(yun)動的準確(que)性。由于傳動鏈(lian)由一系列(lie)元(yuan)件(jian)組(zu)成(cheng)，在(zai)制(zhi)造(zao)(zao)或(huo)(huo)組(zu)裝(zhuang)過程中存在(zai)誤(wu)差(cha)，必然會(hui)影響傳動鏈(lian)的零(ling)件(jian)，導致相對(dui)運(yun)動偏差(cha)和(he)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)精度降低。公法線長度主要用(yong)于表示(shi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)牙齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)分布的較大誤(wu)差(cha)，這是滾(gun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)機(ji)工(gong)(gong)作臺蝸桿副旋轉不均勻造(zao)(zao)成(cheng)的。此外(wai)，圓形(xing)導軌與(yu)分度渦輪(lun)的不同(tong)軸(zhou)或(huo)(huo)圓形(xing)導軌磨損，分齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)掛(gua)輪(lun)過緊或(huo)(huo)過松，分齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)掛(gua)輪(lun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)面顛簸(bo)，會(hui)導致公法線誤(wu)差(cha)過大。齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)形(xing)誤(wu)差(cha)：在(zai)實際滾(gun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)加工(gong)(gong)中，漸(jian)開線齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)形(xing)容易出(chu)現各種(zhong)誤(wu)差(cha)，會(hui)影響齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)傳動的穩(wen)定性。一般(ban)來說，在(zai)滾(gun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)加工(gong)(gong)中，通過齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)坯與(yu)滾(gun)刀(dao)之(zhi)(zhi)間的分齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)來確(que)定漸(jian)開線齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)形(xing)。
