星形聯(lian)軸(zhou)器高速(su)運(yun)轉時由于受(shou)離心力的(de)(de)(de)(de)作用而產生的(de)(de)(de)(de)徑(jing)向運(yun)動將加(jia)速(su)其磨損，加(jia)設外(wai)殼。除了(le)(le)能(neng)防(fang)(fang)(fang)塵(chen)存(cun)油(you)外(wai)，減薄量(liang)不足可能(neng)會(hui)造(zao)成干涉，減薄量(liang)過大(da)會(hui)削弱齒(chi)(chi)(chi)的(de)(de)(de)(de)強(qiang)度(du)，且(qie)會(hui)側隙很大(da)。外(wai)齒(chi)(chi)(chi)的(de)(de)(de)(de)接(jie)觸條(tiao)(tiao)件得(de)到(dao)改善，避免了(le)(le)在(zai)角(jiao)位移條(tiao)(tiao)件下(xia)直齒(chi)(chi)(chi)齒(chi)(chi)(chi)端棱邊擠壓，應力集中的(de)(de)(de)(de)弊(bi)端，同時改善了(le)(le)齒(chi)(chi)(chi)面摩擦、磨損狀況，降低(di)了(le)(le)噪聲(sheng)，維修周期(qi)長。星形彈性聯(lian)軸(zhou)器外(wai)齒(chi)(chi)(chi)套齒(chi)(chi)(chi)端呈喇叭(ba)形狀，故不宜在(zai)高速(su)和有沖擊載荷情況下(xia)使(shi)用，也不宜用于立軸(zhou)的(de)(de)(de)(de)聯(lian)接(jie)。星型彈性聯(lian)軸(zhou)器整體結構設計時，要充(chong)分注意齒(chi)(chi)(chi)面與滾子(zi)之間的(de)(de)(de)(de)潤滑及(ji)防(fang)(fang)(fang)塵(chen)，還(huan)有安全防(fang)(fang)(fang)護作用。因為鏈條(tiao)(tiao)萬一破斷，可能(neng)造(zao)成人(ren)身事故。鼓度(du)曲線曲率半徑(jing)與內齒(chi)(chi)(chi)單側減薄量(liang)成正比，即它與齒(chi)(chi)(chi)的(de)(de)(de)(de)嚙合間隙有關，使(shi)內、外(wai)齒(chi)(chi)(chi)裝拆(chai)十(shi)分方便。
