NGCLZ帶(dai)制動(dong)輪鼓(gu)形(xing)(xing)(xing)(xing)齒(chi)(chi)式(shi)聯軸器(qi)是由齒(chi)(chi)數相同的(de)(de)(de)內齒(chi)(chi)圈和帶(dai)外(wai)齒(chi)(chi)的(de)(de)(de)凸(tu)緣半聯軸器(qi)等(deng)零件組(zu)成(cheng)。外(wai)齒(chi)(chi)分為直齒(chi)(chi)和鼓(gu)形(xing)(xing)(xing)(xing)齒(chi)(chi)兩種齒(chi)(chi)形(xing)(xing)(xing)(xing)，所(suo)謂鼓(gu)形(xing)(xing)(xing)(xing)齒(chi)(chi)即為將外(wai)齒(chi)(chi)制成(cheng)球面(mian)，球面(mian)中心在齒(chi)(chi)輪軸線上，齒(chi)(chi)側間(jian)隙較一般齒(chi)(chi)輪大，鼓(gu)形(xing)(xing)(xing)(xing)齒(chi)(chi)聯軸器(qi)可(ke)允(yun)許較大的(de)(de)(de)角位移(相對于直齒(chi)(chi)聯軸器(qi))，可(ke)改善齒(chi)(chi)的(de)(de)(de)接觸(chu)條件，提高傳遞轉矩的(de)(de)(de)能力，延長使用壽命。

NGCLZ帶制動輪鼓(gu)形齒(chi)(chi)(chi)(chi)式聯軸器在工作時(shi)，兩(liang)軸產生相(xiang)對位移，內外(wai)齒(chi)(chi)(chi)(chi)的齒(chi)(chi)(chi)(chi)面周(zhou)期性作軸向相(xiang)對滑動，必然(ran)形成齒(chi)(chi)(chi)(chi)面磨損和(he)(he)功(gong)率損耗，因此齒(chi)(chi)(chi)(chi)式聯軸器需(xu)在良好潤滑和(he)(he)密封(feng)的狀態下工作。

NGCLZ帶(dai)制動(dong)(dong)(dong)輪鼓形齒式聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)徑(jing)向尺寸小，承(cheng)載能力大，常用于低速重載工況條件的(de)軸(zhou)系(xi)傳(chuan)動(dong)(dong)(dong)，如(ru)冶金(jin)、礦山、起重運(yun)輸行業(ye)，也適(shi)用于石油(you)、化工、通用機(ji)械(xie)等行業(ye)。高精度并(bing)經動(dong)(dong)(dong)平(ping)衡的(de)齒式聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)可用于高速傳(chuan)動(dong)(dong)(dong)，如(ru)燃汽輪機(ji)的(de)軸(zhou)系(xi)傳(chuan)動(dong)(dong)(dong)。由于鼓形齒式聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)的(de)角向補(bu)償(chang)大于直齒式聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)，國(guo)內外均(jun)廣泛采(cai)用鼓形齒式聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)。
