星(xing)(xing)形聯(lian)軸器高(gao)速(su)運轉時由于(yu)受(shou)離心(xin)力的(de)(de)(de)(de)作用而產(chan)生(sheng)的(de)(de)(de)(de)徑向運動(dong)將加速(su)其磨損，加設外殼。除了能(neng)防(fang)塵存油外，減薄量(liang)不足可能(neng)會(hui)造(zao)成干涉(she)，減薄量(liang)過(guo)大會(hui)削弱齒(chi)(chi)的(de)(de)(de)(de)強度，且(qie)會(hui)側(ce)隙很大。外齒(chi)(chi)的(de)(de)(de)(de)接觸(chu)條件得到改善(shan)，避(bi)免了在角位移條件下(xia)直齒(chi)(chi)齒(chi)(chi)端(duan)棱邊擠(ji)壓，應力集中(zhong)的(de)(de)(de)(de)弊端(duan)，同時改善(shan)了齒(chi)(chi)面(mian)摩擦、磨損狀況(kuang)，降低了噪(zao)聲，維修周期長。星(xing)(xing)形彈性(xing)聯(lian)軸器外齒(chi)(chi)套齒(chi)(chi)端(duan)呈(cheng)喇(la)叭形狀，故不宜(yi)(yi)在高(gao)速(su)和有(you)沖擊載荷情況(kuang)下(xia)使(shi)用，也(ye)不宜(yi)(yi)用于(yu)立軸的(de)(de)(de)(de)聯(lian)接。星(xing)(xing)型彈性(xing)聯(lian)軸器整(zheng)體結構設計時，要充分(fen)注意齒(chi)(chi)面(mian)與滾子之間的(de)(de)(de)(de)潤滑及(ji)防(fang)塵，還有(you)安全(quan)防(fang)護(hu)作用。因為(wei)鏈條萬一破斷，可能(neng)造(zao)成人身(shen)事故。鼓度曲線曲率半徑與內齒(chi)(chi)單側(ce)減薄量(liang)成正比，即(ji)它與齒(chi)(chi)的(de)(de)(de)(de)嚙合間隙有(you)關，使(shi)內、外齒(chi)(chi)裝拆十分(fen)方便。
