星(xing)形(xing)聯(lian)(lian)軸器高(gao)速(su)運轉時由于受離心力的作用(yong)而產生的徑(jing)(jing)向(xiang)運動將加(jia)速(su)其磨(mo)損，加(jia)設外(wai)殼(ke)。除了能防塵存油外(wai)，減(jian)(jian)薄量不(bu)足可能會(hui)造(zao)成干(gan)涉，減(jian)(jian)薄量過大會(hui)削弱齒(chi)(chi)的強度，且會(hui)側隙(xi)很大。外(wai)齒(chi)(chi)的接觸(chu)條件得到(dao)改善，避(bi)免(mian)了在(zai)角位移條件下直(zhi)齒(chi)(chi)齒(chi)(chi)端(duan)(duan)棱邊(bian)擠壓，應力集中的弊端(duan)(duan)，同(tong)時改善了齒(chi)(chi)面摩擦、磨(mo)損狀況(kuang)，降低(di)了噪聲，維(wei)修周期長。星(xing)形(xing)彈性(xing)聯(lian)(lian)軸器外(wai)齒(chi)(chi)套(tao)齒(chi)(chi)端(duan)(duan)呈喇叭形(xing)狀，故不(bu)宜在(zai)高(gao)速(su)和(he)有(you)沖擊載荷情況(kuang)下使用(yong)，也(ye)不(bu)宜用(yong)于立軸的聯(lian)(lian)接。星(xing)型彈性(xing)聯(lian)(lian)軸器整體結(jie)構設計(ji)時，要充分注(zhu)意齒(chi)(chi)面與滾子之間(jian)(jian)的潤(run)滑及防塵，還有(you)安全防護作用(yong)。因為(wei)鏈條萬一破斷(duan)，可能造(zao)成人(ren)身事(shi)故。鼓度曲線曲率半(ban)徑(jing)(jing)與內齒(chi)(chi)單側減(jian)(jian)薄量成正比，即它與齒(chi)(chi)的嚙合間(jian)(jian)隙(xi)有(you)關，使內、外(wai)齒(chi)(chi)裝拆十分方便。

星型(xing)聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)有時(shi)被誤認為是(shi)(shi)(shi)梅花聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)，他們安裝后的(de)(de)外(wai)形(xing)(xing)(xing)(xing)(xing)幾乎相似，但是(shi)(shi)(shi)同等型(xing)號下(xia)，星形(xing)(xing)(xing)(xing)(xing)聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)承受的(de)(de)扭力更大，相對梅花聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)，它的(de)(de)內(nei)孔(kong)和外(wai)形(xing)(xing)(xing)(xing)(xing)可(ke)以(yi)做到更小。星形(xing)(xing)(xing)(xing)(xing)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)聚(ju)氨(an)脂彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)體由(you)凸(tu)形(xing)(xing)(xing)(xing)(xing)爪塊限(xian)制(zhi)，聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)是(shi)(shi)(shi)以(yi)工(gong)程(cheng)塑(su)料(liao)作彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)元件(jian)，適用(yong)于(yu)(yu)聯(lian)接(jie)兩(liang)同軸(zhou)(zhou)線的(de)(de)傳動軸(zhou)(zhou)系(xi)，具有補償兩(liang)軸(zhou)(zhou)相對偏移(yi)(yi)、緩(huan)沖(chong)、減震、耐(nai)磨性(xing)(xing)(xing)(xing)(xing)(xing)能，適應場合(he)普遍 ，傳遞轉矩20-35000.N.M,工(gong)作溫度-35-+80攝氏度。星型(xing)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)中的(de)(de)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)元件(jian)是(shi)(shi)(shi)工(gong)程(cheng)塑(su)料(liao)，由(you)于(yu)(yu)該工(gong)程(cheng)塑(su)料(liao)具有良好的(de)(de)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)、緩(huan)沖(chong)性(xing)(xing)(xing)(xing)(xing)(xing)、減震性(xing)(xing)(xing)(xing)(xing)(xing)、耐(nai)磨性(xing)(xing)(xing)(xing)(xing)(xing)，因此能很好的(de)(de)補償兩(liang)傳動軸(zhou)(zhou)系(xi)之間的(de)(de)各種位(wei)移(yi)(yi).星形(xing)(xing)(xing)(xing)(xing)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)的(de)(de)聚(ju)氨(an)脂彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)體由(you)凸(tu)形(xing)(xing)(xing)(xing)(xing)爪塊限(xian)制(zhi)。特點：預應力下(xia)無齒隙(xi)的(de)(de)連接(jie)，用(yong)于(yu)(yu)主軸(zhou)(zhou)傳動、升降平臺和機床等。
