星形聯軸器高速運(yun)轉時(shi)由(you)于(yu)受離心(xin)力的作用(yong)(yong)而產生的徑(jing)向運(yun)動將加速其磨損，加設(she)外殼。除了(le)(le)能(neng)防塵(chen)存(cun)油外，減薄(bo)(bo)量不(bu)足可能(neng)會(hui)造成(cheng)干涉，減薄(bo)(bo)量過大會(hui)削弱齒(chi)(chi)(chi)(chi)(chi)的強度，且會(hui)側隙很大。外齒(chi)(chi)(chi)(chi)(chi)的接觸條件得到(dao)改善(shan)(shan)，避免了(le)(le)在角位移條件下直齒(chi)(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)(chi)端(duan)棱邊擠壓，應力集中的弊端(duan)，同時(shi)改善(shan)(shan)了(le)(le)齒(chi)(chi)(chi)(chi)(chi)面摩(mo)擦、磨損狀況，降低了(le)(le)噪(zao)聲，維修周期長。星形彈性(xing)聯軸器外齒(chi)(chi)(chi)(chi)(chi)套齒(chi)(chi)(chi)(chi)(chi)端(duan)呈喇叭形狀，故不(bu)宜在高速和有沖(chong)擊載荷情況下使用(yong)(yong)，也(ye)不(bu)宜用(yong)(yong)于(yu)立軸的聯接。星型彈性(xing)聯軸器整體(ti)結構(gou)設(she)計時(shi)，要充分注意齒(chi)(chi)(chi)(chi)(chi)面與(yu)滾子之間(jian)的潤滑及防塵(chen)，還有安全(quan)防護作用(yong)(yong)。因為鏈條萬一(yi)破斷，可能(neng)造成(cheng)人身事故。鼓度曲(qu)線(xian)曲(qu)率(lv)半徑(jing)與(yu)內齒(chi)(chi)(chi)(chi)(chi)單側減薄(bo)(bo)量成(cheng)正比，即它與(yu)齒(chi)(chi)(chi)(chi)(chi)的嚙合間(jian)隙有關，使內、外齒(chi)(chi)(chi)(chi)(chi)裝(zhuang)拆(chai)十分方(fang)便。
