星形聯(lian)軸器(qi)(qi)高(gao)速運轉時由(you)于受離心力的(de)作(zuo)(zuo)用(yong)而產生(sheng)的(de)徑向(xiang)運動將加速其(qi)磨損(sun)，加設(she)外殼。除了(le)能防塵存(cun)油外，減(jian)薄(bo)量(liang)不足(zu)可能會(hui)(hui)造(zao)(zao)成干涉(she)，減(jian)薄(bo)量(liang)過大會(hui)(hui)削弱(ruo)齒(chi)(chi)的(de)強度，且會(hui)(hui)側(ce)隙很大。外齒(chi)(chi)的(de)接觸(chu)條(tiao)(tiao)件(jian)得(de)到改(gai)善，避免(mian)了(le)在(zai)(zai)角位移條(tiao)(tiao)件(jian)下(xia)直齒(chi)(chi)齒(chi)(chi)端(duan)(duan)棱邊擠壓(ya)，應(ying)力集(ji)中的(de)弊(bi)端(duan)(duan)，同(tong)時改(gai)善了(le)齒(chi)(chi)面摩(mo)擦、磨損(sun)狀況，降(jiang)低了(le)噪聲，維修(xiu)周期長。星形彈性(xing)(xing)聯(lian)軸器(qi)(qi)外齒(chi)(chi)套齒(chi)(chi)端(duan)(duan)呈喇叭形狀，故不宜在(zai)(zai)高(gao)速和有(you)沖擊載荷(he)情況下(xia)使用(yong)，也不宜用(yong)于立軸的(de)聯(lian)接。星型(xing)彈性(xing)(xing)聯(lian)軸器(qi)(qi)整體(ti)結構(gou)設(she)計時，要(yao)充分注(zhu)意齒(chi)(chi)面與(yu)滾子(zi)之間(jian)的(de)潤滑及防塵，還有(you)安(an)全防護作(zuo)(zuo)用(yong)。因為鏈(lian)條(tiao)(tiao)萬一(yi)破斷，可能造(zao)(zao)成人身事故。鼓(gu)度曲(qu)線曲(qu)率半(ban)徑與(yu)內齒(chi)(chi)單側(ce)減(jian)薄(bo)量(liang)成正比，即它與(yu)齒(chi)(chi)的(de)嚙合間(jian)隙有(you)關，使內、外齒(chi)(chi)裝拆十分方(fang)便。
