齒式聯軸器是運用內外齒齒合來完成兩截連軸器連接的，因為內外唇間有不錯的相互配合，好幾個齒另外觸碰，齒側空隙一般較傳動齒輪大，因而具備不錯的徑向，軸向，角向賠償工作能力，尤其是鼓形齒式聯軸器能考慮很大的角向偏移。因為在高速運行時，各連軸器會產生三向飄移，使齒側表面相對滑動，因此 齒式聯軸器需有靠譜的潤化。

齒(chi)(chi)式聯(lian)軸(zhou)器(qi)(qi)假(jia)如無法得到非常(chang)好(hao)的(de)(de)(de)潤(run)化(hua)，可能大大縮短連軸(zhou)器(qi)(qi)的(de)(de)(de)使(shi)用期(qi)，立(li)即危害生產流水線(xian)的(de)(de)(de)運行(xing)。要常(chang)常(chang)定(ding)期(qi)維護，按(an)時(shi)(shi)(shi)(shi)填(tian)補，按(an)時(shi)(shi)(shi)(shi)拆換(huan)，確保(bao)潤(run)滑脂的(de)(de)(de)總數和品質，隨時(shi)(shi)(shi)(shi)隨地留意填(tian)補，按(an)時(shi)(shi)(shi)(shi)清(qing)理連軸(zhou)器(qi)(qi)元(yuan)器(qi)(qi)件，拆換(huan)新油，以防囤(dun)積油垢過多，危害潤(run)化(hua)實(shi)際效果。有的(de)(de)(de)生產廠家(jia)換(huan)潤(run)滑液的(de)(de)(de)時(shi)(shi)(shi)(shi)間(jian)間(jian)隔為(wei)6-12個(ge)月，潤(run)滑液不(bu)夠，將造成(cheng) 損壞(huai)，齒(chi)(chi)合(he)的(de)(de)(de)齒(chi)(chi)造成(cheng)黏(nian)著(zhu)，假(jia)如2年維修一次，這類潤(run)化(hua)標(biao)準不(bu)可以考慮連軸(zhou)器(qi)(qi)的(de)(de)(de)要求，很有可能造成(cheng) 齒(chi)(chi)式聯(lian)軸(zhou)器(qi)(qi)無效。
