凸緣(yuan)聯(lian)(lian)軸(zhou)器(qi)屬于剛(gang)(gang)性聯(lian)(lian)軸(zhou)器(qi)，是(shi)(shi)(shi)把兩(liang)個帶有凸緣(yuan)的半聯(lian)(lian)軸(zhou)器(qi)用普通(tong)平鍵分別與(yu)兩(liang)軸(zhou)連(lian)接，然后用螺(luo)(luo)栓把兩(liang)個半聯(lian)(lian)軸(zhou)器(qi)連(lian)成(cheng)(cheng)一體，以(yi)傳(chuan)(chuan)遞(di)運動(dong)(dong)和(he)(he)轉矩(ju)(ju)。這種聯(lian)(lian)軸(zhou)器(qi)有兩(liang)種主要的結構形式：靠鉸制(zhi)孔用螺(luo)(luo)栓來(lai)實現兩(liang)軸(zhou)對中和(he)(he)靠螺(luo)(luo)栓桿(gan)承(cheng)受(shou)擠壓與(yu)剪切來(lai)傳(chuan)(chuan)遞(di)轉矩(ju)(ju)；靠一個半聯(lian)(lian)軸(zhou)器(qi)上的凸肩與(yu)另一個半聯(lian)(lian)軸(zhou)器(qi)上的凹槽相配合而(er)對中。連(lian)接兩(liang)個半聯(lian)(lian)軸(zhou)器(qi)的螺(luo)(luo)栓可(ke)以(yi)采用A級和(he)(he)B級的普通(tong)螺(luo)(luo)栓，轉矩(ju)(ju)靠兩(liang)個半聯(lian)(lian)軸(zhou)器(qi)結合面的摩擦(ca)力矩(ju)(ju)來(lai)傳(chuan)(chuan)遞(di)。凸緣(yuan)聯(lian)(lian)軸(zhou)器(qi)結構簡(jian)單，制(zhi)造方便(bian)，成(cheng)(cheng)本較(jiao)(jiao)低，工作可(ke)靠，裝(zhuang)拆、維(wei)護(hu)均較(jiao)(jiao)簡(jian)便(bian)，傳(chuan)(chuan)遞(di)轉矩(ju)(ju)較(jiao)(jiao)大，能保證(zheng)兩(liang)軸(zhou)具(ju)有較(jiao)(jiao)高的對中精度，一般常用于載(zai)荷平穩，高速或傳(chuan)(chuan)動(dong)(dong)精度要求較(jiao)(jiao)高的軸(zhou)系(xi)傳(chuan)(chuan)動(dong)(dong)。凸緣(yuan)聯(lian)(lian)軸(zhou)器(qi)不(bu)具(ju)備徑向、軸(zhou)向和(he)(he)角向補償。剛(gang)(gang)性聯(lian)(lian)軸(zhou)器(qi)是(shi)(shi)(shi)一種扭轉剛(gang)(gang)性的聯(lian)(lian)軸(zhou)器(qi)，即使承(cheng)受(shou)負載(zai)時也(ye)無任何(he)回轉間隙，即便(bian)是(shi)(shi)(shi)有偏差產生負荷時，剛(gang)(gang)性聯(lian)(lian)軸(zhou)器(qi)還(huan)是(shi)(shi)(shi)剛(gang)(gang)性傳(chuan)(chuan)遞(di)扭矩(ju)(ju)。
