星形聯(lian)(lian)軸(zhou)(zhou)(zhou)器高速(su)運轉時(shi)由(you)于(yu)受(shou)離心力(li)的(de)作用而產生的(de)徑向運動將加速(su)其(qi)磨損，加設外(wai)(wai)殼。除了(le)能(neng)防(fang)塵存油外(wai)(wai)，減(jian)薄量不(bu)足(zu)可能(neng)會(hui)造(zao)成干涉，減(jian)薄量過(guo)大會(hui)削弱齒(chi)(chi)的(de)強(qiang)度，且會(hui)側隙很(hen)大。外(wai)(wai)齒(chi)(chi)的(de)接觸(chu)條件(jian)(jian)得到改善(shan)，避免了(le)在(zai)角位移條件(jian)(jian)下(xia)(xia)直齒(chi)(chi)齒(chi)(chi)端棱邊擠(ji)壓，應力(li)集中(zhong)的(de)弊(bi)端，同時(shi)改善(shan)了(le)齒(chi)(chi)面摩擦、磨損狀況，降低了(le)噪聲(sheng)，維修周(zhou)期長。星形彈(dan)性聯(lian)(lian)軸(zhou)(zhou)(zhou)器外(wai)(wai)齒(chi)(chi)套(tao)齒(chi)(chi)端呈喇叭形狀，故(gu)不(bu)宜(yi)在(zai)高速(su)和有(you)沖擊載荷(he)情況下(xia)(xia)使用，也不(bu)宜(yi)用于(yu)立(li)軸(zhou)(zhou)(zhou)的(de)聯(lian)(lian)接。星型(xing)彈(dan)性聯(lian)(lian)軸(zhou)(zhou)(zhou)器整體結(jie)構設計時(shi)，要充分(fen)(fen)注意(yi)齒(chi)(chi)面與滾子之間的(de)潤(run)滑及(ji)防(fang)塵，還有(you)安全防(fang)護作用。因為鏈條萬(wan)一破(po)斷(duan)，可能(neng)造(zao)成人身事故(gu)。鼓度曲線曲率半(ban)徑與內齒(chi)(chi)單側減(jian)薄量成正(zheng)比，即它與齒(chi)(chi)的(de)嚙(nie)合間隙有(you)關，使內、外(wai)(wai)齒(chi)(chi)裝(zhuang)拆十分(fen)(fen)方便(bian)。

星(xing)(xing)型聯(lian)軸(zhou)器(qi)有時被誤認(ren)為是(shi)梅(mei)花聯(lian)軸(zhou)器(qi)，他們安裝(zhuang)后的外(wai)形(xing)幾乎相(xiang)(xiang)(xiang)似(si)，但是(shi)同等型號下，星(xing)(xing)形(xing)聯(lian)軸(zhou)器(qi)承受的扭力(li)更大，相(xiang)(xiang)(xiang)對梅(mei)花聯(lian)軸(zhou)器(qi)，它(ta)的內孔和外(wai)形(xing)可以(yi)做到更小(xiao)。星(xing)(xing)形(xing)彈(dan)(dan)(dan)性(xing)(xing)(xing)聯(lian)軸(zhou)器(qi)聚氨脂彈(dan)(dan)(dan)性(xing)(xing)(xing)體(ti)由(you)凸(tu)(tu)形(xing)爪塊限制(zhi)，聯(lian)軸(zhou)器(qi)是(shi)以(yi)工(gong)程塑料(liao)作彈(dan)(dan)(dan)性(xing)(xing)(xing)元件，適用于聯(lian)接兩(liang)同軸(zhou)線的傳動軸(zhou)系(xi)，具有補償兩(liang)軸(zhou)相(xiang)(xiang)(xiang)對偏移、緩(huan)沖、減震、耐磨性(xing)(xing)(xing)能，適應場合普遍(bian) ，傳遞(di)轉矩20-35000.N.M,工(gong)作溫度-35-+80攝氏度。星(xing)(xing)型彈(dan)(dan)(dan)性(xing)(xing)(xing)聯(lian)軸(zhou)器(qi)中的彈(dan)(dan)(dan)性(xing)(xing)(xing)元件是(shi)工(gong)程塑料(liao)，由(you)于該工(gong)程塑料(liao)具有良好的彈(dan)(dan)(dan)性(xing)(xing)(xing)、緩(huan)沖性(xing)(xing)(xing)、減震性(xing)(xing)(xing)、耐磨性(xing)(xing)(xing)，因(yin)此能很好的補償兩(liang)傳動軸(zhou)系(xi)之間的各(ge)種位(wei)移.星(xing)(xing)形(xing)彈(dan)(dan)(dan)性(xing)(xing)(xing)聯(lian)軸(zhou)器(qi)的聚氨脂彈(dan)(dan)(dan)性(xing)(xing)(xing)體(ti)由(you)凸(tu)(tu)形(xing)爪塊限制(zhi)。特點：預(yu)應力(li)下無(wu)齒(chi)隙(xi)的連接，用于主軸(zhou)傳動、升降平(ping)臺和機床等。
