星形(xing)聯軸(zhou)(zhou)器(qi)高(gao)速運(yun)轉時由于受離(li)心(xin)力的(de)(de)作用而(er)產(chan)生的(de)(de)徑向運(yun)動將加速其(qi)磨損(sun)(sun)，加設外殼。除(chu)了(le)能(neng)防(fang)塵存油(you)外，減(jian)(jian)薄(bo)(bo)量不(bu)足可能(neng)會(hui)(hui)造(zao)成(cheng)干(gan)涉，減(jian)(jian)薄(bo)(bo)量過(guo)大會(hui)(hui)削弱齒(chi)(chi)的(de)(de)強度，且會(hui)(hui)側隙(xi)很大。外齒(chi)(chi)的(de)(de)接觸條(tiao)件得到改(gai)善，避免(mian)了(le)在(zai)角(jiao)位移(yi)條(tiao)件下直齒(chi)(chi)齒(chi)(chi)端(duan)棱(leng)邊擠壓，應力集中的(de)(de)弊端(duan)，同時改(gai)善了(le)齒(chi)(chi)面摩擦、磨損(sun)(sun)狀況，降低了(le)噪聲(sheng)，維修周期長。星形(xing)彈性(xing)聯軸(zhou)(zhou)器(qi)外齒(chi)(chi)套(tao)齒(chi)(chi)端(duan)呈喇叭(ba)形(xing)狀，故不(bu)宜(yi)在(zai)高(gao)速和有沖擊載荷情況下使用，也不(bu)宜(yi)用于立軸(zhou)(zhou)的(de)(de)聯接。星型彈性(xing)聯軸(zhou)(zhou)器(qi)整(zheng)體結構設計時，要充分注意齒(chi)(chi)面與(yu)滾子之(zhi)間(jian)的(de)(de)潤滑及防(fang)塵，還有安全防(fang)護作用。因為鏈條(tiao)萬一破斷，可能(neng)造(zao)成(cheng)人(ren)身事故。鼓(gu)度曲(qu)線曲(qu)率半徑與(yu)內齒(chi)(chi)單側減(jian)(jian)薄(bo)(bo)量成(cheng)正比，即它與(yu)齒(chi)(chi)的(de)(de)嚙合間(jian)隙(xi)有關，使內、外齒(chi)(chi)裝拆十分方便。
