星(xing)形(xing)聯(lian)(lian)軸器(qi)高(gao)速運轉時由于受(shou)離心力(li)的(de)(de)作(zuo)用而產(chan)生(sheng)的(de)(de)徑向運動將加速其(qi)磨損，加設外殼。除了(le)能防塵存油外，減(jian)薄(bo)量(liang)不足可能會(hui)(hui)(hui)造成干涉，減(jian)薄(bo)量(liang)過大會(hui)(hui)(hui)削(xue)弱齒(chi)(chi)(chi)(chi)(chi)的(de)(de)強度(du)(du)，且會(hui)(hui)(hui)側(ce)隙(xi)很大。外齒(chi)(chi)(chi)(chi)(chi)的(de)(de)接觸條件(jian)得到改(gai)善，避免了(le)在角位(wei)移條件(jian)下直(zhi)齒(chi)(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)(chi)端(duan)棱邊擠壓(ya)，應力(li)集中(zhong)的(de)(de)弊(bi)端(duan)，同時改(gai)善了(le)齒(chi)(chi)(chi)(chi)(chi)面摩(mo)擦、磨損狀況，降低了(le)噪聲，維修周期(qi)長。星(xing)形(xing)彈(dan)性(xing)聯(lian)(lian)軸器(qi)外齒(chi)(chi)(chi)(chi)(chi)套齒(chi)(chi)(chi)(chi)(chi)端(duan)呈喇叭形(xing)狀，故不宜在高(gao)速和有(you)沖擊載荷(he)情況下使用，也不宜用于立軸的(de)(de)聯(lian)(lian)接。星(xing)型彈(dan)性(xing)聯(lian)(lian)軸器(qi)整體結構設計時，要充分注(zhu)意齒(chi)(chi)(chi)(chi)(chi)面與(yu)滾(gun)子之(zhi)間的(de)(de)潤滑及防塵，還有(you)安全防護作(zuo)用。因為(wei)鏈條萬一破斷(duan)，可能造成人身(shen)事故。鼓度(du)(du)曲(qu)線曲(qu)率半徑與(yu)內(nei)齒(chi)(chi)(chi)(chi)(chi)單側(ce)減(jian)薄(bo)量(liang)成正比，即它與(yu)齒(chi)(chi)(chi)(chi)(chi)的(de)(de)嚙合間隙(xi)有(you)關，使內(nei)、外齒(chi)(chi)(chi)(chi)(chi)裝拆十分方便。
