星(xing)形(xing)聯軸(zhou)器高(gao)速運轉時由(you)于受離(li)心力的(de)作用而產(chan)生的(de)徑(jing)向運動將加速其磨損，加設外殼。除了(le)能防塵(chen)存油外，減薄量不足可能會(hui)造成(cheng)干涉，減薄量過大會(hui)削弱齒(chi)(chi)(chi)的(de)強度，且(qie)會(hui)側隙很大。外齒(chi)(chi)(chi)的(de)接觸條(tiao)件得到改(gai)善(shan)，避免了(le)在角位(wei)移條(tiao)件下(xia)直齒(chi)(chi)(chi)齒(chi)(chi)(chi)端(duan)(duan)棱邊擠壓，應力集中(zhong)的(de)弊(bi)端(duan)(duan)，同時改(gai)善(shan)了(le)齒(chi)(chi)(chi)面摩擦、磨損狀(zhuang)況，降(jiang)低了(le)噪聲，維修周期長。星(xing)形(xing)彈(dan)性(xing)聯軸(zhou)器外齒(chi)(chi)(chi)套齒(chi)(chi)(chi)端(duan)(duan)呈(cheng)喇(la)叭形(xing)狀(zhuang)，故不宜(yi)在高(gao)速和有(you)沖擊(ji)載荷(he)情況下(xia)使用，也不宜(yi)用于立(li)軸(zhou)的(de)聯接。星(xing)型(xing)彈(dan)性(xing)聯軸(zhou)器整體結構設計時，要充分注意齒(chi)(chi)(chi)面與滾子之間的(de)潤滑及防塵(chen)，還(huan)有(you)安全防護作用。因為鏈條(tiao)萬一破斷，可能造成(cheng)人身事故。鼓度曲線曲率(lv)半徑(jing)與內(nei)齒(chi)(chi)(chi)單側減薄量成(cheng)正比，即(ji)它與齒(chi)(chi)(chi)的(de)嚙(nie)合間隙有(you)關，使內(nei)、外齒(chi)(chi)(chi)裝拆十(shi)分方(fang)便。
