制造齒(chi)(chi)式聯(lian)軸器(qi)是由齒(chi)(chi)數相同的內齒(chi)(chi)圈和(he)帶外(wai)齒(chi)(chi)的凸緣半聯(lian)軸器(qi)等零件(jian)組(zu)成(cheng)。外(wai)齒(chi)(chi)分為直齒(chi)(chi)和(he)鼓(gu)(gu)形(xing)(xing)(xing)齒(chi)(chi)兩(liang)種齒(chi)(chi)形(xing)(xing)(xing)，所謂(wei)鼓(gu)(gu)形(xing)(xing)(xing)齒(chi)(chi)即為將外(wai)齒(chi)(chi)制成(cheng)球(qiu)面，球(qiu)面中心在齒(chi)(chi)輪(lun)軸線上，齒(chi)(chi)側間(jian)隙較(jiao)一般齒(chi)(chi)輪(lun)大(da)，鼓(gu)(gu)形(xing)(xing)(xing)齒(chi)(chi)聯(lian)軸器(qi)可允許較(jiao)大(da)的角位移(相對于直齒(chi)(chi)聯(lian)軸器(qi))，可改善(shan)齒(chi)(chi)的接觸條件(jian)，提高傳遞(di)轉(zhuan)矩(ju)的能(neng)力，延長使(shi)用壽命。
制造齒式(shi)聯軸器在(zai)工作時(shi)，兩軸產生(sheng)相對位移，內外齒的(de)齒面周期性作軸向相對滑動，必然形成齒面磨(mo)損和功率(lv)損耗，因此(ci)齒式(shi)聯軸器需在(zai)良好潤滑和密封的(de)狀態下(xia)工作。
制造齒(chi)式(shi)聯(lian)軸器(qi)(qi)徑向尺寸小，承載(zai)能力大(da)，常用(yong)(yong)于(yu)(yu)(yu)低速(su)(su)重載(zai)工況條件的(de)軸系傳動，如(ru)冶(ye)金、礦(kuang)山(shan)、起重運輸行業，也適用(yong)(yong)于(yu)(yu)(yu)石油、化工、通用(yong)(yong)機(ji)(ji)械等行業。高(gao)精度并(bing)經動平衡的(de)齒(chi)式(shi)聯(lian)軸器(qi)(qi)可用(yong)(yong)于(yu)(yu)(yu)高(gao)速(su)(su)傳動，如(ru)燃汽輪機(ji)(ji)的(de)軸系傳動。由(you)于(yu)(yu)(yu)鼓(gu)形(xing)齒(chi)式(shi)聯(lian)軸器(qi)(qi)的(de)角向補(bu)償大(da)于(yu)(yu)(yu)直齒(chi)式(shi)聯(lian)軸器(qi)(qi)，國內外均廣泛(fan)采用(yong)(yong)鼓(gu)形(xing)齒(chi)式(shi)聯(lian)軸器(qi)(qi)。
