對輪聯軸器慣性(xing)主軸(zhou)(zhou)(zhou)線(xian)與旋轉(zhuan)軸(zhou)(zhou)(zhou)線(xian)之(zhi)間(jian)重心位置偏心量的(de)(de)(de)可能值(zhi)是平方(fang)和(he)方(fang)根值(zhi)而決定的(de)(de)(de)，主要由兩(liang)(liang)半(ban)聯(lian)軸(zhou)(zhou)(zhou)器(qi)和(he)聯(lian)接(jie)螺栓組成，對輪聯(lian)軸(zhou)(zhou)(zhou)器(qi)軸(zhou)(zhou)(zhou)套孔(kong)(kong)(kong)裝配前(qian)，鏜削切割和(he)鍵(jian)槽的(de)(de)(de)修(xiu)整聯(lian)軸(zhou)(zhou)(zhou)器(qi)端(duan)面(mian)和(he)其它表面(mian)的(de)(de)(de)加工(gong)等。半(ban)聯(lian)軸(zhou)(zhou)(zhou)器(qi)的(de)(de)(de)軸(zhou)(zhou)(zhou)套孔(kong)(kong)(kong)有圓(yuan)錐孔(kong)(kong)(kong)和(he)圓(yuan)柱孔(kong)(kong)(kong)兩(liang)(liang)種形式，圓(yuan)錐孔(kong)(kong)(kong)比圓(yuan)柱孔(kong)(kong)(kong)在工(gong)藝特(te)性(xing)上有較(jiao)多(duo)的(de)(de)(de)特(te)點，圓(yuan)錐形軸(zhou)(zhou)(zhou)套孔(kong)(kong)(kong)容易獲得相配合(he)部件之(zhi)間(jian)的(de)(de)(de)同心。

對輪聯(lian)(lian)軸(zhou)器(qi)在工(gong)作過程(cheng)中(zhong)(zhong)，并且會(hui)帶來燃油(you)消(xiao)耗(hao)空氣污染等后果，由(you)于承(cheng)受(shou)咬入沖擊動(dong)載(zai)荷(he)，使得聯(lian)(lian)軸(zhou)器(qi)受(shou)到峰值轉矩(ju)，聯(lian)(lian)軸(zhou)器(qi)承(cheng)載(zai)能力(li)下降，并在短時間內失效，從而直(zhi)接(jie)影響其正常工(gong)作，其中(zhong)(zhong)的(de)較薄弱環節進行替換或(huo)維修(xiu)是重要(yao)和實用的(de)。聯(lian)(lian)軸(zhou)器(qi)兩軸(zhou)相對半(ban)徑變位要(yao)求較好，找耦合同心度為0.2~0.6mm，存在很大困難。如果在駕駛過程(cheng)中(zhong)(zhong)螺栓松(song)動(dong)，泵(beng)裝置的(de)振動(dong)和噪音(yin)可(ke)能會(hui)變大。
