中間(jian)套鼓形(xing)(xing)齒(chi)(chi)(chi)(chi)(chi)(chi)式(shi)聯軸(zhou)(zhou)器是由齒(chi)(chi)(chi)(chi)(chi)(chi)數相同的內齒(chi)(chi)(chi)(chi)(chi)(chi)圈和帶外(wai)齒(chi)(chi)(chi)(chi)(chi)(chi)的凸(tu)緣半(ban)聯軸(zhou)(zhou)器等零件(jian)組成。外(wai)齒(chi)(chi)(chi)(chi)(chi)(chi)分為直齒(chi)(chi)(chi)(chi)(chi)(chi)和鼓形(xing)(xing)齒(chi)(chi)(chi)(chi)(chi)(chi)兩種齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)(xing)，所(suo)謂鼓形(xing)(xing)齒(chi)(chi)(chi)(chi)(chi)(chi)即為將外(wai)齒(chi)(chi)(chi)(chi)(chi)(chi)制(zhi)成球面，球面中心在齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)軸(zhou)(zhou)線上(shang)，齒(chi)(chi)(chi)(chi)(chi)(chi)側(ce)間(jian)隙(xi)較一般(ban)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)大(da)，鼓形(xing)(xing)齒(chi)(chi)(chi)(chi)(chi)(chi)聯軸(zhou)(zhou)器可(ke)允許較大(da)的角(jiao)位移(相對于(yu)直齒(chi)(chi)(chi)(chi)(chi)(chi)聯軸(zhou)(zhou)器)，可(ke)改善齒(chi)(chi)(chi)(chi)(chi)(chi)的接觸條件(jian)，提高(gao)傳遞轉矩的能力，延長使用壽命(ming)。

中間套(tao)鼓形(xing)(xing)齒(chi)式聯軸(zhou)器在工作(zuo)時(shi)，兩軸(zhou)產生(sheng)相對位(wei)移(yi)，內外齒(chi)的齒(chi)面周期性(xing)作(zuo)軸(zhou)向相對滑動，必然形(xing)(xing)成齒(chi)面磨損(sun)和功率(lv)損(sun)耗，因此齒(chi)式聯軸(zhou)器需在良好潤滑和密封的狀態(tai)下工作(zuo)。

中間套鼓(gu)形齒(chi)式聯(lian)(lian)(lian)軸(zhou)器(qi)徑(jing)向(xiang)尺寸小(xiao)，承載能力(li)大，常用于低速重載工(gong)況條件(jian)的(de)軸(zhou)系(xi)(xi)傳(chuan)動(dong)，如冶金、礦(kuang)山、起重運輸(shu)行(xing)業(ye)(ye)，也(ye)適用于石油、化工(gong)、通用機械(xie)等行(xing)業(ye)(ye)。高精度并(bing)經動(dong)平衡的(de)齒(chi)式聯(lian)(lian)(lian)軸(zhou)器(qi)可用于高速傳(chuan)動(dong)，如燃汽輪機的(de)軸(zhou)系(xi)(xi)傳(chuan)動(dong)。由(you)于鼓(gu)形齒(chi)式聯(lian)(lian)(lian)軸(zhou)器(qi)的(de)角向(xiang)補償大于直齒(chi)式聯(lian)(lian)(lian)軸(zhou)器(qi)，國內(nei)外(wai)均廣泛采用鼓(gu)形齒(chi)式聯(lian)(lian)(lian)軸(zhou)器(qi)。
