ngcl型帶制動輪鼓形(xing)(xing)齒(chi)(chi)(chi)(chi)式聯(lian)軸(zhou)器(qi)是由齒(chi)(chi)(chi)(chi)數相同(tong)的內(nei)齒(chi)(chi)(chi)(chi)圈和帶外(wai)齒(chi)(chi)(chi)(chi)的凸緣(yuan)半聯(lian)軸(zhou)器(qi)等零件組(zu)成。外(wai)齒(chi)(chi)(chi)(chi)分為(wei)直齒(chi)(chi)(chi)(chi)和鼓形(xing)(xing)齒(chi)(chi)(chi)(chi)兩種(zhong)齒(chi)(chi)(chi)(chi)形(xing)(xing)，所謂鼓形(xing)(xing)齒(chi)(chi)(chi)(chi)即為(wei)將外(wai)齒(chi)(chi)(chi)(chi)制成球(qiu)(qiu)面，球(qiu)(qiu)面中(zhong)心在(zai)齒(chi)(chi)(chi)(chi)輪軸(zhou)線上，齒(chi)(chi)(chi)(chi)側間隙較一(yi)般齒(chi)(chi)(chi)(chi)輪大，鼓形(xing)(xing)齒(chi)(chi)(chi)(chi)聯(lian)軸(zhou)器(qi)可允許較大的角(jiao)位移(yi)(相對于直齒(chi)(chi)(chi)(chi)聯(lian)軸(zhou)器(qi))，可改(gai)善齒(chi)(chi)(chi)(chi)的接觸條件，提高傳遞(di)轉矩(ju)的能力，延長使(shi)用(yong)壽命(ming)。

ngcl型(xing)帶制動輪(lun)鼓(gu)形齒式(shi)聯軸(zhou)器在工(gong)作時(shi)，兩軸(zhou)產生相對(dui)位(wei)移(yi)，內外齒的齒面周期性作軸(zhou)向相對(dui)滑動，必然(ran)形成齒面磨損和(he)(he)功率損耗，因此齒式(shi)聯軸(zhou)器需在良好潤滑和(he)(he)密封的狀態下工(gong)作。

ngcl型帶制動(dong)(dong)輪(lun)鼓(gu)形(xing)齒式聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)徑向(xiang)尺寸小，承(cheng)載能力(li)大，常用于低(di)速重(zhong)載工(gong)況條件的(de)軸(zhou)(zhou)(zhou)系(xi)傳(chuan)動(dong)(dong)，如(ru)冶金、礦山、起重(zhong)運(yun)輸行業，也適用于石油、化工(gong)、通用機(ji)械等行業。高精度并經動(dong)(dong)平衡(heng)的(de)齒式聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)可(ke)用于高速傳(chuan)動(dong)(dong)，如(ru)燃汽(qi)輪(lun)機(ji)的(de)軸(zhou)(zhou)(zhou)系(xi)傳(chuan)動(dong)(dong)。由于鼓(gu)形(xing)齒式聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)的(de)角向(xiang)補(bu)償(chang)大于直齒式聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)，國內外(wai)均(jun)廣(guang)泛采用鼓(gu)形(xing)齒式聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)。
