星(xing)(xing)形聯(lian)軸器高速運轉時由于受離心(xin)力的(de)(de)(de)(de)作用(yong)而產生的(de)(de)(de)(de)徑向運動將加速其磨(mo)損，加設外(wai)(wai)殼。除了(le)能防(fang)塵存油外(wai)(wai)，減(jian)薄量不足(zu)可能會造(zao)成干涉，減(jian)薄量過大(da)會削弱(ruo)齒(chi)(chi)的(de)(de)(de)(de)強度，且(qie)會側(ce)(ce)隙很大(da)。外(wai)(wai)齒(chi)(chi)的(de)(de)(de)(de)接觸條件(jian)得到改(gai)善(shan)，避免了(le)在(zai)角位移條件(jian)下直齒(chi)(chi)齒(chi)(chi)端棱邊擠(ji)壓，應力集中的(de)(de)(de)(de)弊端，同時改(gai)善(shan)了(le)齒(chi)(chi)面摩(mo)擦、磨(mo)損狀(zhuang)(zhuang)況，降低(di)了(le)噪(zao)聲，維修周期(qi)長。星(xing)(xing)形彈(dan)性(xing)聯(lian)軸器外(wai)(wai)齒(chi)(chi)套齒(chi)(chi)端呈喇叭形狀(zhuang)(zhuang)，故(gu)不宜(yi)在(zai)高速和有沖擊載荷(he)情況下使用(yong)，也不宜(yi)用(yong)于立軸的(de)(de)(de)(de)聯(lian)接。星(xing)(xing)型彈(dan)性(xing)聯(lian)軸器整體結構設計(ji)時，要(yao)充分注意(yi)齒(chi)(chi)面與滾子(zi)之間(jian)的(de)(de)(de)(de)潤滑(hua)及(ji)防(fang)塵，還有安全防(fang)護作用(yong)。因為鏈條萬一破斷，可能造(zao)成人身事(shi)故(gu)。鼓度曲(qu)線(xian)曲(qu)率半(ban)徑與內(nei)齒(chi)(chi)單側(ce)(ce)減(jian)薄量成正比，即(ji)它與齒(chi)(chi)的(de)(de)(de)(de)嚙合間(jian)隙有關，使內(nei)、外(wai)(wai)齒(chi)(chi)裝拆十(shi)分方便。
