國產(chan)齒(chi)(chi)(chi)(chi)式聯(lian)(lian)軸(zhou)(zhou)器(qi)是由齒(chi)(chi)(chi)(chi)數相同的內齒(chi)(chi)(chi)(chi)圈和(he)帶外(wai)齒(chi)(chi)(chi)(chi)的凸緣半聯(lian)(lian)軸(zhou)(zhou)器(qi)等零件組成。外(wai)齒(chi)(chi)(chi)(chi)分為(wei)直齒(chi)(chi)(chi)(chi)和(he)鼓(gu)形齒(chi)(chi)(chi)(chi)兩種齒(chi)(chi)(chi)(chi)形，所謂鼓(gu)形齒(chi)(chi)(chi)(chi)即為(wei)將外(wai)齒(chi)(chi)(chi)(chi)制成球面，球面中(zhong)心在齒(chi)(chi)(chi)(chi)輪軸(zhou)(zhou)線上，齒(chi)(chi)(chi)(chi)側間(jian)隙(xi)較一般齒(chi)(chi)(chi)(chi)輪大，鼓(gu)形齒(chi)(chi)(chi)(chi)聯(lian)(lian)軸(zhou)(zhou)器(qi)可允(yun)許較大的角位移(相對于直齒(chi)(chi)(chi)(chi)聯(lian)(lian)軸(zhou)(zhou)器(qi))，可改善(shan)齒(chi)(chi)(chi)(chi)的接(jie)觸條件，提高(gao)傳遞轉(zhuan)矩(ju)的能力，延長使(shi)用壽命。

國(guo)產齒式聯軸(zhou)器在(zai)工作時，兩軸(zhou)產生(sheng)相對位移，內外齒的(de)齒面周期性(xing)作軸(zhou)向相對滑(hua)動，必(bi)然形成齒面磨損和功率損耗，因(yin)此齒式聯軸(zhou)器需在(zai)良好(hao)潤滑(hua)和密封(feng)的(de)狀態(tai)下工作。

國(guo)產(chan)齒(chi)式(shi)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)徑向(xiang)(xiang)尺寸小，承載能力大，常用于(yu)(yu)低(di)速(su)重載工(gong)況條件的軸(zhou)(zhou)系傳動(dong)(dong)，如冶金、礦山、起重運輸(shu)行業，也適(shi)用于(yu)(yu)石油、化工(gong)、通用機械等行業。高精度并經動(dong)(dong)平衡的齒(chi)式(shi)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)可用于(yu)(yu)高速(su)傳動(dong)(dong)，如燃汽(qi)輪機的軸(zhou)(zhou)系傳動(dong)(dong)。由于(yu)(yu)鼓(gu)形(xing)(xing)齒(chi)式(shi)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)的角向(xiang)(xiang)補償大于(yu)(yu)直齒(chi)式(shi)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)，國(guo)內外均廣泛采用鼓(gu)形(xing)(xing)齒(chi)式(shi)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)。
