星形聯(lian)軸(zhou)器高(gao)速(su)(su)運轉時由于受離心力的作(zuo)用(yong)(yong)(yong)而(er)產生(sheng)的徑向(xiang)運動將加(jia)速(su)(su)其(qi)磨(mo)損(sun)，加(jia)設(she)外殼。除了能防塵(chen)存油外，減薄(bo)量不(bu)足可能會(hui)造成(cheng)(cheng)干涉，減薄(bo)量過大會(hui)削(xue)弱(ruo)齒(chi)的強度，且會(hui)側(ce)隙(xi)很(hen)大。外齒(chi)的接(jie)(jie)觸條件得(de)到改善，避免(mian)了在角(jiao)位(wei)移條件下(xia)直齒(chi)齒(chi)端(duan)棱邊擠壓(ya)，應力集中的弊(bi)端(duan)，同時改善了齒(chi)面摩擦、磨(mo)損(sun)狀況，降低了噪聲，維修(xiu)周期長。星形彈性(xing)聯(lian)軸(zhou)器外齒(chi)套齒(chi)端(duan)呈喇叭形狀，故(gu)不(bu)宜(yi)在高(gao)速(su)(su)和(he)有沖擊載荷情況下(xia)使用(yong)(yong)(yong)，也不(bu)宜(yi)用(yong)(yong)(yong)于立(li)軸(zhou)的聯(lian)接(jie)(jie)。星型(xing)彈性(xing)聯(lian)軸(zhou)器整體結構(gou)設(she)計時，要充(chong)分注意齒(chi)面與滾子之間(jian)的潤滑及防塵(chen)，還有安全防護作(zuo)用(yong)(yong)(yong)。因為鏈條萬(wan)一破斷，可能造成(cheng)(cheng)人身事故(gu)。鼓度曲線(xian)曲率(lv)半徑與內齒(chi)單側(ce)減薄(bo)量成(cheng)(cheng)正比，即它與齒(chi)的嚙合(he)間(jian)隙(xi)有關，使內、外齒(chi)裝(zhuang)拆十分方(fang)便。
