星形聯(lian)軸器高速運(yun)轉時由于受離心力的(de)(de)(de)作用(yong)而產生的(de)(de)(de)徑向運(yun)動將加速其(qi)磨損，加設外(wai)(wai)殼(ke)。除了能防塵(chen)存(cun)油外(wai)(wai)，減(jian)薄量不(bu)足可能會(hui)(hui)造成(cheng)干(gan)涉，減(jian)薄量過大會(hui)(hui)削弱齒(chi)(chi)的(de)(de)(de)強度，且會(hui)(hui)側隙(xi)很大。外(wai)(wai)齒(chi)(chi)的(de)(de)(de)接(jie)觸條(tiao)件(jian)得到改善(shan)，避(bi)免了在(zai)角位移(yi)條(tiao)件(jian)下直(zhi)齒(chi)(chi)齒(chi)(chi)端棱邊擠壓，應力集中的(de)(de)(de)弊(bi)端，同時改善(shan)了齒(chi)(chi)面(mian)摩擦、磨損狀況(kuang)，降低了噪聲(sheng)，維修周期長。星形彈性(xing)聯(lian)軸器外(wai)(wai)齒(chi)(chi)套齒(chi)(chi)端呈喇叭(ba)形狀，故(gu)不(bu)宜(yi)在(zai)高速和有沖擊載荷情(qing)況(kuang)下使(shi)用(yong)，也不(bu)宜(yi)用(yong)于立軸的(de)(de)(de)聯(lian)接(jie)。星型(xing)彈性(xing)聯(lian)軸器整(zheng)體(ti)結構設計時，要充(chong)分(fen)注意齒(chi)(chi)面(mian)與(yu)滾子(zi)之間的(de)(de)(de)潤滑及(ji)防塵(chen)，還有安全防護(hu)作用(yong)。因為鏈條(tiao)萬(wan)一破斷，可能造成(cheng)人身(shen)事(shi)故(gu)。鼓(gu)度曲(qu)線曲(qu)率半徑與(yu)內齒(chi)(chi)單側減(jian)薄量成(cheng)正比，即(ji)它與(yu)齒(chi)(chi)的(de)(de)(de)嚙合(he)間隙(xi)有關，使(shi)內、外(wai)(wai)齒(chi)(chi)裝拆十(shi)分(fen)方便。
