星(xing)(xing)形聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)高速(su)(su)運(yun)(yun)轉時(shi)由于受離心力的作用而(er)產生的徑向運(yun)(yun)動將(jiang)加速(su)(su)其磨損，加設外(wai)殼。除了(le)(le)能(neng)防塵存油外(wai)，減薄量不(bu)足可能(neng)會造(zao)成干(gan)涉(she)，減薄量過大會削弱齒(chi)(chi)的強(qiang)度(du)，且(qie)會側隙很大。外(wai)齒(chi)(chi)的接觸條(tiao)(tiao)件得到改善，避(bi)免了(le)(le)在角(jiao)位移條(tiao)(tiao)件下(xia)直(zhi)齒(chi)(chi)齒(chi)(chi)端(duan)棱邊擠壓(ya)，應力集中的弊端(duan)，同時(shi)改善了(le)(le)齒(chi)(chi)面摩擦、磨損狀況(kuang)，降低(di)了(le)(le)噪聲，維修周期(qi)長(chang)。星(xing)(xing)形彈(dan)性(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)外(wai)齒(chi)(chi)套齒(chi)(chi)端(duan)呈喇叭形狀，故不(bu)宜在高速(su)(su)和(he)有(you)(you)沖擊載(zai)荷情況(kuang)下(xia)使(shi)用，也不(bu)宜用于立軸(zhou)的聯(lian)(lian)接。星(xing)(xing)型彈(dan)性(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)整體(ti)結構設計時(shi)，要充分注意齒(chi)(chi)面與(yu)滾子之間的潤滑及防塵，還(huan)有(you)(you)安(an)全防護(hu)作用。因為(wei)鏈條(tiao)(tiao)萬一(yi)破斷，可能(neng)造(zao)成人身事(shi)故。鼓度(du)曲線曲率半(ban)徑與(yu)內(nei)(nei)齒(chi)(chi)單側減薄量成正比，即它與(yu)齒(chi)(chi)的嚙合間隙有(you)(you)關，使(shi)內(nei)(nei)、外(wai)齒(chi)(chi)裝拆十分方便。
