凸(tu)緣(yuan)(yuan)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)屬于(yu)剛(gang)性聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)，是把兩(liang)(liang)個(ge)(ge)帶有(you)(you)凸(tu)緣(yuan)(yuan)的半聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)用(yong)普(pu)(pu)通(tong)平鍵(jian)分別與(yu)兩(liang)(liang)軸(zhou)(zhou)連接，然后用(yong)螺栓(shuan)把兩(liang)(liang)個(ge)(ge)半聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)連成一體，以(yi)傳(chuan)(chuan)(chuan)(chuan)遞(di)運動(dong)和轉(zhuan)矩。這種聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)有(you)(you)兩(liang)(liang)種主要的結(jie)(jie)構形式：靠鉸制孔用(yong)螺栓(shuan)來實現兩(liang)(liang)軸(zhou)(zhou)對中和靠螺栓(shuan)桿承(cheng)受(shou)擠(ji)壓與(yu)剪切(qie)來傳(chuan)(chuan)(chuan)(chuan)遞(di)轉(zhuan)矩；靠一個(ge)(ge)半聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)上的凸(tu)肩與(yu)另一個(ge)(ge)半聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)上的凹槽相配合而對中。連接兩(liang)(liang)個(ge)(ge)半聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)的螺栓(shuan)可以(yi)采用(yong)A級和B級的普(pu)(pu)通(tong)螺栓(shuan)，轉(zhuan)矩靠兩(liang)(liang)個(ge)(ge)半聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)結(jie)(jie)合面的摩擦力(li)矩來傳(chuan)(chuan)(chuan)(chuan)遞(di)。凸(tu)緣(yuan)(yuan)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)結(jie)(jie)構簡單，制造方便(bian)，成本較(jiao)低，工作可靠，裝拆(chai)、維護(hu)均較(jiao)簡便(bian)，傳(chuan)(chuan)(chuan)(chuan)遞(di)轉(zhuan)矩較(jiao)大(da)，能(neng)保證兩(liang)(liang)軸(zhou)(zhou)具有(you)(you)較(jiao)高的對中精(jing)(jing)度(du)，一般常用(yong)于(yu)載荷(he)(he)平穩，高速或傳(chuan)(chuan)(chuan)(chuan)動(dong)精(jing)(jing)度(du)要求(qiu)較(jiao)高的軸(zhou)(zhou)系傳(chuan)(chuan)(chuan)(chuan)動(dong)。凸(tu)緣(yuan)(yuan)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)不具備(bei)徑(jing)向、軸(zhou)(zhou)向和角(jiao)向補(bu)償(chang)。剛(gang)性聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)是一種扭轉(zhuan)剛(gang)性的聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)，即(ji)使承(cheng)受(shou)負(fu)載時(shi)也無任何回(hui)轉(zhuan)間(jian)隙，即(ji)便(bian)是有(you)(you)偏差產生負(fu)荷(he)(he)時(shi)，剛(gang)性聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)還是剛(gang)性傳(chuan)(chuan)(chuan)(chuan)遞(di)扭矩。
