凸(tu)緣聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)屬(shu)于剛性(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)，是(shi)把(ba)(ba)兩(liang)個(ge)(ge)帶(dai)有(you)(you)凸(tu)緣的(de)半(ban)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)用(yong)普(pu)通平鍵分別與(yu)兩(liang)軸(zhou)連(lian)(lian)接，然后用(yong)螺栓把(ba)(ba)兩(liang)個(ge)(ge)半(ban)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)連(lian)(lian)成一(yi)(yi)(yi)體(ti)，以(yi)傳(chuan)遞(di)(di)運(yun)動(dong)和(he)轉(zhuan)(zhuan)(zhuan)矩(ju)(ju)(ju)。這種聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)有(you)(you)兩(liang)種主要(yao)的(de)結(jie)構(gou)形式：靠(kao)鉸制孔(kong)用(yong)螺栓來(lai)實(shi)現兩(liang)軸(zhou)對中(zhong)(zhong)和(he)靠(kao)螺栓桿承受(shou)擠壓(ya)與(yu)剪(jian)切來(lai)傳(chuan)遞(di)(di)轉(zhuan)(zhuan)(zhuan)矩(ju)(ju)(ju)；靠(kao)一(yi)(yi)(yi)個(ge)(ge)半(ban)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)上(shang)的(de)凸(tu)肩與(yu)另一(yi)(yi)(yi)個(ge)(ge)半(ban)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)上(shang)的(de)凹(ao)槽相配(pei)合(he)而對中(zhong)(zhong)。連(lian)(lian)接兩(liang)個(ge)(ge)半(ban)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)的(de)螺栓可以(yi)采用(yong)A級和(he)B級的(de)普(pu)通螺栓，轉(zhuan)(zhuan)(zhuan)矩(ju)(ju)(ju)靠(kao)兩(liang)個(ge)(ge)半(ban)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)結(jie)合(he)面的(de)摩(mo)擦力矩(ju)(ju)(ju)來(lai)傳(chuan)遞(di)(di)。凸(tu)緣聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)結(jie)構(gou)簡單，制造(zao)方便，成本(ben)較(jiao)低(di)，工作可靠(kao)，裝拆、維護均較(jiao)簡便，傳(chuan)遞(di)(di)轉(zhuan)(zhuan)(zhuan)矩(ju)(ju)(ju)較(jiao)大(da)，能(neng)保證兩(liang)軸(zhou)具有(you)(you)較(jiao)高的(de)對中(zhong)(zhong)精度，一(yi)(yi)(yi)般常用(yong)于載(zai)荷(he)平穩，高速或傳(chuan)動(dong)精度要(yao)求(qiu)較(jiao)高的(de)軸(zhou)系傳(chuan)動(dong)。凸(tu)緣聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)不具備徑向(xiang)、軸(zhou)向(xiang)和(he)角(jiao)向(xiang)補償。剛性(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)是(shi)一(yi)(yi)(yi)種扭轉(zhuan)(zhuan)(zhuan)剛性(xing)的(de)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)，即使承受(shou)負載(zai)時(shi)也無任何(he)回轉(zhuan)(zhuan)(zhuan)間隙(xi)，即便是(shi)有(you)(you)偏差產生負荷(he)時(shi)，剛性(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)還是(shi)剛性(xing)傳(chuan)遞(di)(di)扭矩(ju)(ju)(ju)。
