星形聯(lian)軸器高(gao)速(su)運轉時由于受離心(xin)力的(de)(de)作用(yong)而(er)產生的(de)(de)徑(jing)向(xiang)運動將加(jia)速(su)其磨損，加(jia)設(she)外(wai)(wai)殼。除了(le)(le)能(neng)防(fang)塵(chen)存(cun)油外(wai)(wai)，減(jian)(jian)薄量不足可能(neng)會(hui)造成干涉，減(jian)(jian)薄量過(guo)大會(hui)削弱(ruo)齒(chi)(chi)的(de)(de)強度，且(qie)會(hui)側隙(xi)很大。外(wai)(wai)齒(chi)(chi)的(de)(de)接觸條件得到(dao)改善，避免了(le)(le)在角位移條件下(xia)(xia)直齒(chi)(chi)齒(chi)(chi)端(duan)棱邊擠壓，應力集中(zhong)的(de)(de)弊端(duan)，同時改善了(le)(le)齒(chi)(chi)面摩(mo)擦、磨損狀(zhuang)況，降低了(le)(le)噪聲，維修周(zhou)期長。星形彈性聯(lian)軸器外(wai)(wai)齒(chi)(chi)套(tao)齒(chi)(chi)端(duan)呈(cheng)喇叭(ba)形狀(zhuang)，故(gu)不宜在高(gao)速(su)和(he)有沖擊(ji)載(zai)荷情(qing)況下(xia)(xia)使(shi)用(yong)，也不宜用(yong)于立軸的(de)(de)聯(lian)接。星型彈性聯(lian)軸器整體結構設(she)計時，要(yao)充分(fen)注意齒(chi)(chi)面與(yu)滾(gun)子之間的(de)(de)潤滑及防(fang)塵(chen)，還(huan)有安全防(fang)護作用(yong)。因為鏈條萬一破斷，可能(neng)造成人(ren)身事故(gu)。鼓度曲(qu)線曲(qu)率半徑(jing)與(yu)內(nei)齒(chi)(chi)單側減(jian)(jian)薄量成正比，即它與(yu)齒(chi)(chi)的(de)(de)嚙合間隙(xi)有關，使(shi)內(nei)、外(wai)(wai)齒(chi)(chi)裝拆十(shi)分(fen)方便。
