對輪聯軸器慣(guan)性(xing)主(zhu)軸(zhou)(zhou)線(xian)與旋(xuan)轉軸(zhou)(zhou)線(xian)之間(jian)重(zhong)心位置偏心量的(de)(de)可能(neng)值是平方和(he)(he)方根值而決定的(de)(de)，主(zhu)要由兩半(ban)聯(lian)軸(zhou)(zhou)器(qi)和(he)(he)聯(lian)接螺栓組(zu)成(cheng)，對輪聯(lian)軸(zhou)(zhou)器(qi)軸(zhou)(zhou)套孔裝配(pei)前，鏜削切割(ge)和(he)(he)鍵槽(cao)的(de)(de)修整聯(lian)軸(zhou)(zhou)器(qi)端面(mian)和(he)(he)其它表面(mian)的(de)(de)加工(gong)等(deng)。半(ban)聯(lian)軸(zhou)(zhou)器(qi)的(de)(de)軸(zhou)(zhou)套孔有圓(yuan)(yuan)錐(zhui)孔和(he)(he)圓(yuan)(yuan)柱孔兩種形式，圓(yuan)(yuan)錐(zhui)孔比圓(yuan)(yuan)柱孔在工(gong)藝特(te)性(xing)上有較多(duo)的(de)(de)特(te)點，圓(yuan)(yuan)錐(zhui)形軸(zhou)(zhou)套孔容易獲得相配(pei)合部件之間(jian)的(de)(de)同心。

對輪聯軸器(qi)在(zai)工(gong)作過(guo)程中(zhong)，并且(qie)會帶來燃(ran)油(you)消(xiao)耗空氣(qi)污(wu)染等后(hou)果，由于承(cheng)(cheng)受(shou)咬(yao)入沖擊動載(zai)荷，使得(de)聯軸器(qi)受(shou)到峰值(zhi)轉矩，聯軸器(qi)承(cheng)(cheng)載(zai)能(neng)(neng)力下降(jiang)，并在(zai)短時間內(nei)失效，從(cong)而直接(jie)影響其(qi)正常工(gong)作，其(qi)中(zhong)的較薄弱環節進(jin)行替換或維修是重要和實用的。聯軸器(qi)兩軸相對半徑(jing)變位要求較好，找(zhao)耦合(he)同(tong)心度為(wei)0.2~0.6mm，存在(zai)很大困難。如果在(zai)駕駛過(guo)程中(zhong)螺栓(shuan)松動，泵(beng)裝置的振(zhen)動和噪(zao)音可能(neng)(neng)會變大。

凸(tu)(tu)緣聯(lian)(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)屬于(yu)(yu)剛(gang)性聯(lian)(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)，是(shi)(shi)把(ba)兩個帶有凸(tu)(tu)緣的(de)半聯(lian)(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)用(yong)普(pu)(pu)通平鍵(jian)分(fen)別與(yu)兩軸(zhou)(zhou)(zhou)連(lian)(lian)接，然后用(yong)螺(luo)栓把(ba)兩個半聯(lian)(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)連(lian)(lian)成(cheng)一體，以傳(chuan)(chuan)遞(di)運動(dong)和(he)轉(zhuan)(zhuan)(zhuan)(zhuan)矩。這種聯(lian)(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)有兩種主要的(de)結(jie)構(gou)形式：靠(kao)鉸制(zhi)孔用(yong)螺(luo)栓來實現兩軸(zhou)(zhou)(zhou)對中和(he)靠(kao)螺(luo)栓桿承受(shou)擠壓(ya)與(yu)剪切來傳(chuan)(chuan)遞(di)轉(zhuan)(zhuan)(zhuan)(zhuan)矩；靠(kao)一個半聯(lian)(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)上的(de)凸(tu)(tu)肩與(yu)另(ling)一個半聯(lian)(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)上的(de)凹槽相配合而(er)對中。連(lian)(lian)接兩個半聯(lian)(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)的(de)螺(luo)栓可以采用(yong)A級(ji)和(he)B級(ji)的(de)普(pu)(pu)通螺(luo)栓，轉(zhuan)(zhuan)(zhuan)(zhuan)矩靠(kao)兩個半聯(lian)(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)結(jie)合面(mian)的(de)摩(mo)擦力(li)矩來傳(chuan)(chuan)遞(di)。凸(tu)(tu)緣聯(lian)(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)結(jie)構(gou)簡(jian)單，制(zhi)造方便，成(cheng)本較低，工作可靠(kao)，裝拆、維護(hu)均較簡(jian)便，傳(chuan)(chuan)遞(di)轉(zhuan)(zhuan)(zhuan)(zhuan)矩較大，能保證兩軸(zhou)(zhou)(zhou)具(ju)有較高的(de)對中精度，一般常(chang)用(yong)于(yu)(yu)載荷(he)平穩(wen)，高速(su)或傳(chuan)(chuan)動(dong)精度要求較高的(de)軸(zhou)(zhou)(zhou)系(xi)傳(chuan)(chuan)動(dong)。凸(tu)(tu)緣聯(lian)(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)不具(ju)備徑向、軸(zhou)(zhou)(zhou)向和(he)角向補償(chang)。剛(gang)性聯(lian)(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)是(shi)(shi)一種扭轉(zhuan)(zhuan)(zhuan)(zhuan)剛(gang)性的(de)聯(lian)(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)，即使承受(shou)負(fu)載時也無任(ren)何回轉(zhuan)(zhuan)(zhuan)(zhuan)間隙，即便是(shi)(shi)有偏差產生負(fu)荷(he)時，剛(gang)性聯(lian)(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)還是(shi)(shi)剛(gang)性傳(chuan)(chuan)遞(di)扭矩。
