星(xing)(xing)形(xing)聯軸(zhou)(zhou)器(qi)高速運轉時由于(yu)受離心(xin)力(li)的(de)(de)作用而產(chan)生的(de)(de)徑向運動(dong)將加速其(qi)磨損，加設(she)外(wai)(wai)殼。除了(le)(le)能(neng)防(fang)塵存油外(wai)(wai)，減薄量不足可能(neng)會造(zao)成(cheng)干涉，減薄量過大(da)會削弱齒(chi)(chi)(chi)(chi)(chi)的(de)(de)強(qiang)度(du)(du)，且(qie)會側隙(xi)很大(da)。外(wai)(wai)齒(chi)(chi)(chi)(chi)(chi)的(de)(de)接(jie)觸條件得(de)到改善，避免(mian)了(le)(le)在角(jiao)位移條件下直齒(chi)(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)(chi)端棱邊擠壓，應(ying)力(li)集(ji)中的(de)(de)弊端，同(tong)時改善了(le)(le)齒(chi)(chi)(chi)(chi)(chi)面摩擦、磨損狀況(kuang)，降(jiang)低了(le)(le)噪聲，維修(xiu)周期長(chang)。星(xing)(xing)形(xing)彈性聯軸(zhou)(zhou)器(qi)外(wai)(wai)齒(chi)(chi)(chi)(chi)(chi)套齒(chi)(chi)(chi)(chi)(chi)端呈喇叭(ba)形(xing)狀，故不宜(yi)在高速和有沖擊載荷情況(kuang)下使用，也(ye)不宜(yi)用于(yu)立軸(zhou)(zhou)的(de)(de)聯接(jie)。星(xing)(xing)型(xing)彈性聯軸(zhou)(zhou)器(qi)整(zheng)體(ti)結構設(she)計時，要充分注意齒(chi)(chi)(chi)(chi)(chi)面與滾子之間的(de)(de)潤(run)滑及防(fang)塵，還有安全防(fang)護作用。因為鏈條萬一破斷，可能(neng)造(zao)成(cheng)人身事故。鼓度(du)(du)曲線曲率半徑與內齒(chi)(chi)(chi)(chi)(chi)單側減薄量成(cheng)正比，即它與齒(chi)(chi)(chi)(chi)(chi)的(de)(de)嚙合間隙(xi)有關，使內、外(wai)(wai)齒(chi)(chi)(chi)(chi)(chi)裝拆十分方便。
