星形(xing)(xing)聯(lian)軸器高速運轉時由于(yu)受(shou)離心(xin)力(li)的(de)作(zuo)用而(er)產生的(de)徑向運動將加速其磨損，加設外(wai)殼(ke)。除了能(neng)(neng)防塵(chen)(chen)存油外(wai)，減(jian)薄(bo)量(liang)不(bu)足可能(neng)(neng)會(hui)造成(cheng)干涉，減(jian)薄(bo)量(liang)過大(da)會(hui)削弱齒(chi)(chi)的(de)強度(du)，且會(hui)側隙很大(da)。外(wai)齒(chi)(chi)的(de)接觸(chu)條件得到改善，避(bi)免了在角位移條件下直齒(chi)(chi)齒(chi)(chi)端棱邊(bian)擠(ji)壓，應力(li)集中(zhong)的(de)弊(bi)端，同時改善了齒(chi)(chi)面摩擦、磨損狀況(kuang)，降低了噪聲(sheng)，維修周期長。星形(xing)(xing)彈性聯(lian)軸器外(wai)齒(chi)(chi)套齒(chi)(chi)端呈喇叭形(xing)(xing)狀，故不(bu)宜在高速和有(you)沖擊(ji)載荷(he)情況(kuang)下使用，也不(bu)宜用于(yu)立軸的(de)聯(lian)接。星型彈性聯(lian)軸器整體結構設計時，要充分(fen)注意齒(chi)(chi)面與滾(gun)子之(zhi)間的(de)潤滑及防塵(chen)(chen)，還有(you)安全防護作(zuo)用。因為鏈條萬一破斷，可能(neng)(neng)造成(cheng)人身事故。鼓度(du)曲線(xian)曲率半徑與內(nei)齒(chi)(chi)單側減(jian)薄(bo)量(liang)成(cheng)正比，即它與齒(chi)(chi)的(de)嚙合間隙有(you)關，使內(nei)、外(wai)齒(chi)(chi)裝(zhuang)拆十分(fen)方便。
