2、齒(chi)(chi)(chi)面(mian)(mian)膠合：對于高速重載(zai)的(de)(de)(de)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)傳動中，因齒(chi)(chi)(chi)面(mian)(mian)間的(de)(de)(de)摩擦(ca)力(li)較(jiao)大(da)，相對速大(da)，致使嚙合區溫(wen)過(guo)高，一(yi)旦潤滑條(tiao)件不良，齒(chi)(chi)(chi)面(mian)(mian)間的(de)(de)(de)油膜(mo)便會消(xiao)失，使得兩(liang)輪(lun)(lun)(lun)(lun)齒(chi)(chi)(chi)的(de)(de)(de)金屬表面(mian)(mian)直接接觸，從而發(fa)生(sheng)(sheng)相互粘(zhan)結。當兩(liang)齒(chi)(chi)(chi)面(mian)(mian)繼續相對運(yun)動時，較(jiao)硬(ying)的(de)(de)(de)齒(chi)(chi)(chi)面(mian)(mian)將較(jiao)軟的(de)(de)(de)齒(chi)(chi)(chi)面(mian)(mian)上(shang)的(de)(de)(de)部分材(cai)料沿(yan)滑動方向撕下而形(xing)(xing)(xing)成(cheng)溝(gou)紋。3、齒(chi)(chi)(chi)面(mian)(mian)塑性(xing)(xing)變形(xing)(xing)(xing)：在沖擊載(zai)荷(he)或重載(zai)下，齒(chi)(chi)(chi)面(mian)(mian)易產生(sheng)(sheng)局部的(de)(de)(de)塑性(xing)(xing)變形(xing)(xing)(xing)，從而使漸開線齒(chi)(chi)(chi)廓的(de)(de)(de)曲(qu)面(mian)(mian)發(fa)生(sheng)(sheng)變形(xing)(xing)(xing)。車用(yong)(yong)(yong)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)油和工業齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)油的(de)(de)(de)區別？齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)，相信大(da)家已經不陌生(sheng)(sheng)，知道(dao)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)是(shi)一(yi)種(zhong)傳動裝置，但是(shi)要想保證(zheng)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)的(de)(de)(de)正(zheng)常使用(yong)(yong)(yong)，是(shi)用(yong)(yong)(yong)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)油來進行潤滑的(de)(de)(de)。不同(tong)用(yong)(yong)(yong)途的(de)(de)(de)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)適(shi)用(yong)(yong)(yong)的(de)(de)(de)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)油也(ye)不一(yi)樣，就拿(na)車用(yong)(yong)(yong)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)與(yu)工業齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)來說吧，不能用(yong)(yong)(yong)同(tong)樣的(de)(de)(de)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)油，車用(yong)(yong)(yong)齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)油和工業齒(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)油有什么區別呢?
