星形(xing)(xing)聯(lian)(lian)軸器高(gao)速運(yun)轉時由于(yu)受離心(xin)力的(de)作(zuo)用(yong)(yong)而產(chan)生(sheng)的(de)徑(jing)(jing)向運(yun)動將加(jia)速其磨(mo)損，加(jia)設外殼(ke)。除了能防(fang)塵(chen)存油(you)外，減薄(bo)量(liang)(liang)不(bu)(bu)(bu)足(zu)可能會造成(cheng)干涉，減薄(bo)量(liang)(liang)過大會削(xue)弱齒(chi)(chi)的(de)強(qiang)度，且會側隙(xi)很大。外齒(chi)(chi)的(de)接觸(chu)條(tiao)件得到(dao)改善(shan)，避免了在角(jiao)位移條(tiao)件下直齒(chi)(chi)齒(chi)(chi)端(duan)棱邊擠(ji)壓，應(ying)力集中的(de)弊端(duan)，同時改善(shan)了齒(chi)(chi)面摩擦、磨(mo)損狀況，降低了噪聲，維修周(zhou)期長。星形(xing)(xing)彈性(xing)聯(lian)(lian)軸器外齒(chi)(chi)套齒(chi)(chi)端(duan)呈喇叭形(xing)(xing)狀，故(gu)不(bu)(bu)(bu)宜在高(gao)速和(he)有沖擊載荷情況下使用(yong)(yong)，也不(bu)(bu)(bu)宜用(yong)(yong)于(yu)立(li)軸的(de)聯(lian)(lian)接。星型彈性(xing)聯(lian)(lian)軸器整體(ti)結構設計時，要充分注(zhu)意齒(chi)(chi)面與滾(gun)子之(zhi)間的(de)潤滑及防(fang)塵(chen)，還(huan)有安全防(fang)護作(zuo)用(yong)(yong)。因為鏈(lian)條(tiao)萬一破(po)斷，可能造成(cheng)人身事故(gu)。鼓度曲(qu)線(xian)曲(qu)率半徑(jing)(jing)與內(nei)齒(chi)(chi)單側減薄(bo)量(liang)(liang)成(cheng)正比，即它與齒(chi)(chi)的(de)嚙合間隙(xi)有關，使內(nei)、外齒(chi)(chi)裝拆十分方(fang)便。
