星形聯軸(zhou)(zhou)器(qi)高(gao)速運(yun)轉時(shi)由(you)于(yu)受離(li)心(xin)力的作用(yong)(yong)(yong)而產(chan)生的徑向運(yun)動(dong)將加速其磨損(sun)(sun)，加設外(wai)(wai)(wai)殼。除(chu)了(le)能防(fang)塵(chen)存油外(wai)(wai)(wai)，減(jian)薄(bo)量(liang)不(bu)足可(ke)能會造成干涉，減(jian)薄(bo)量(liang)過(guo)大會削(xue)弱齒(chi)的強度，且會側(ce)隙很大。外(wai)(wai)(wai)齒(chi)的接(jie)(jie)觸條件(jian)(jian)得(de)到(dao)改善，避免了(le)在角位移(yi)條件(jian)(jian)下(xia)直齒(chi)齒(chi)端(duan)棱邊擠壓，應力集中的弊端(duan)，同時(shi)改善了(le)齒(chi)面摩擦、磨損(sun)(sun)狀(zhuang)況，降(jiang)低了(le)噪聲，維修周期長。星形彈性聯軸(zhou)(zhou)器(qi)外(wai)(wai)(wai)齒(chi)套齒(chi)端(duan)呈喇叭形狀(zhuang)，故不(bu)宜在高(gao)速和有沖擊載荷情況下(xia)使(shi)用(yong)(yong)(yong)，也不(bu)宜用(yong)(yong)(yong)于(yu)立軸(zhou)(zhou)的聯接(jie)(jie)。星型彈性聯軸(zhou)(zhou)器(qi)整體結構設計時(shi)，要充分注(zhu)意齒(chi)面與(yu)滾子之間的潤滑及防(fang)塵(chen)，還有安全防(fang)護作用(yong)(yong)(yong)。因為鏈(lian)條萬一破斷，可(ke)能造成人身事故。鼓度曲(qu)線曲(qu)率半徑與(yu)內齒(chi)單側(ce)減(jian)薄(bo)量(liang)成正比，即它與(yu)齒(chi)的嚙(nie)合(he)間隙有關(guan)，使(shi)內、外(wai)(wai)(wai)齒(chi)裝拆(chai)十分方(fang)便(bian)。

星(xing)(xing)(xing)型(xing)(xing)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)有時被(bei)誤認為(wei)是梅花聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)，他們安(an)裝后的(de)(de)(de)外形(xing)(xing)(xing)幾乎相似，但是同等型(xing)(xing)號下，星(xing)(xing)(xing)形(xing)(xing)(xing)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)承受的(de)(de)(de)扭(niu)力更大，相對(dui)梅花聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)，它的(de)(de)(de)內孔和外形(xing)(xing)(xing)可以做到更小(xiao)。星(xing)(xing)(xing)形(xing)(xing)(xing)彈性(xing)(xing)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)聚氨脂(zhi)彈性(xing)(xing)體由(you)凸形(xing)(xing)(xing)爪塊(kuai)限制，聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)是以工(gong)程塑料(liao)(liao)(liao)作彈性(xing)(xing)元(yuan)件，適用于聯(lian)(lian)接(jie)兩同軸(zhou)(zhou)(zhou)(zhou)(zhou)線的(de)(de)(de)傳(chuan)動軸(zhou)(zhou)(zhou)(zhou)(zhou)系(xi)，具有補償(chang)兩軸(zhou)(zhou)(zhou)(zhou)(zhou)相對(dui)偏移、緩(huan)沖、減震(zhen)、耐磨性(xing)(xing)能，適應場(chang)合普遍 ，傳(chuan)遞轉矩20-35000.N.M,工(gong)作溫度(du)-35-+80攝(she)氏度(du)。星(xing)(xing)(xing)型(xing)(xing)彈性(xing)(xing)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)中的(de)(de)(de)彈性(xing)(xing)元(yuan)件是工(gong)程塑料(liao)(liao)(liao)，由(you)于該工(gong)程塑料(liao)(liao)(liao)具有良好的(de)(de)(de)彈性(xing)(xing)、緩(huan)沖性(xing)(xing)、減震(zhen)性(xing)(xing)、耐磨性(xing)(xing)，因此能很好的(de)(de)(de)補償(chang)兩傳(chuan)動軸(zhou)(zhou)(zhou)(zhou)(zhou)系(xi)之間的(de)(de)(de)各(ge)種位移.星(xing)(xing)(xing)形(xing)(xing)(xing)彈性(xing)(xing)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)的(de)(de)(de)聚氨脂(zhi)彈性(xing)(xing)體由(you)凸形(xing)(xing)(xing)爪塊(kuai)限制。特點：預應力下無齒隙的(de)(de)(de)連接(jie)，用于主軸(zhou)(zhou)(zhou)(zhou)(zhou)傳(chuan)動、升降平臺和機床等。
