星形聯(lian)(lian)軸(zhou)(zhou)器高速(su)運轉時由于(yu)受離心力的(de)(de)(de)作用(yong)而產(chan)生的(de)(de)(de)徑(jing)(jing)向運動(dong)將加(jia)速(su)其(qi)磨損，加(jia)設外(wai)殼。除了(le)能(neng)防(fang)塵存(cun)油外(wai)，減(jian)薄量不(bu)(bu)(bu)足(zu)可能(neng)會造成(cheng)(cheng)干涉，減(jian)薄量過大(da)會削弱齒的(de)(de)(de)強度(du)，且會側隙(xi)很大(da)。外(wai)齒的(de)(de)(de)接(jie)觸條件(jian)得到改善，避(bi)免(mian)了(le)在角位移條件(jian)下直(zhi)齒齒端(duan)棱邊擠壓，應力集中的(de)(de)(de)弊端(duan)，同時改善了(le)齒面摩(mo)擦、磨損狀況，降低了(le)噪聲，維(wei)修(xiu)周期長。星形彈性聯(lian)(lian)軸(zhou)(zhou)器外(wai)齒套齒端(duan)呈喇叭形狀，故不(bu)(bu)(bu)宜在高速(su)和有(you)(you)沖擊(ji)載荷情況下使(shi)用(yong)，也不(bu)(bu)(bu)宜用(yong)于(yu)立軸(zhou)(zhou)的(de)(de)(de)聯(lian)(lian)接(jie)。星型彈性聯(lian)(lian)軸(zhou)(zhou)器整體結構設計時，要充分注意齒面與滾子之間(jian)的(de)(de)(de)潤滑及防(fang)塵，還有(you)(you)安全防(fang)護作用(yong)。因為鏈條萬一破斷，可能(neng)造成(cheng)(cheng)人(ren)身事故。鼓度(du)曲線曲率半徑(jing)(jing)與內(nei)齒單(dan)側減(jian)薄量成(cheng)(cheng)正比，即(ji)它與齒的(de)(de)(de)嚙合間(jian)隙(xi)有(you)(you)關，使(shi)內(nei)、外(wai)齒裝拆十分方便。

星型聯(lian)軸(zhou)(zhou)(zhou)器有時被誤(wu)認(ren)為(wei)是(shi)梅(mei)花聯(lian)軸(zhou)(zhou)(zhou)器，他們安裝后的(de)(de)(de)外形幾(ji)乎(hu)相(xiang)似(si)，但是(shi)同(tong)等型號(hao)下，星形聯(lian)軸(zhou)(zhou)(zhou)器承受的(de)(de)(de)扭力更(geng)大，相(xiang)對梅(mei)花聯(lian)軸(zhou)(zhou)(zhou)器，它的(de)(de)(de)內孔和(he)外形可以做到更(geng)小。星形彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)聯(lian)軸(zhou)(zhou)(zhou)器聚氨脂(zhi)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)體(ti)由凸(tu)形爪塊限制，聯(lian)軸(zhou)(zhou)(zhou)器是(shi)以工程塑(su)料作(zuo)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)元件(jian)，適用(yong)于(yu)聯(lian)接兩(liang)同(tong)軸(zhou)(zhou)(zhou)線的(de)(de)(de)傳動(dong)軸(zhou)(zhou)(zhou)系，具(ju)有補償兩(liang)軸(zhou)(zhou)(zhou)相(xiang)對偏移、緩沖(chong)、減震、耐(nai)磨(mo)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)能，適應場合普遍 ，傳遞轉矩20-35000.N.M,工作(zuo)溫度(du)-35-+80攝氏度(du)。星型彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)聯(lian)軸(zhou)(zhou)(zhou)器中的(de)(de)(de)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)元件(jian)是(shi)工程塑(su)料，由于(yu)該(gai)工程塑(su)料具(ju)有良好(hao)的(de)(de)(de)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)、緩沖(chong)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)、減震性(xing)(xing)(xing)(xing)(xing)(xing)(xing)、耐(nai)磨(mo)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)，因此能很好(hao)的(de)(de)(de)補償兩(liang)傳動(dong)軸(zhou)(zhou)(zhou)系之間(jian)的(de)(de)(de)各種位移.星形彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)聯(lian)軸(zhou)(zhou)(zhou)器的(de)(de)(de)聚氨脂(zhi)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)體(ti)由凸(tu)形爪塊限制。特點：預應力下無齒隙的(de)(de)(de)連接，用(yong)于(yu)主軸(zhou)(zhou)(zhou)傳動(dong)、升降平臺和(he)機床等。
