星(xing)形(xing)聯軸器(qi)(qi)高速運轉(zhuan)時由于受(shou)離心(xin)力(li)的(de)作用(yong)(yong)而產生(sheng)的(de)徑向(xiang)運動將加速其(qi)磨損，加設外(wai)殼(ke)。除了(le)能(neng)防(fang)塵存油外(wai)，減(jian)薄量(liang)不(bu)足(zu)可(ke)能(neng)會(hui)造成(cheng)干涉，減(jian)薄量(liang)過大會(hui)削弱(ruo)齒(chi)(chi)的(de)強度，且會(hui)側隙很大。外(wai)齒(chi)(chi)的(de)接觸(chu)條(tiao)件(jian)得到改善，避免了(le)在角位移條(tiao)件(jian)下(xia)直齒(chi)(chi)齒(chi)(chi)端(duan)(duan)棱(leng)邊(bian)擠壓，應力(li)集中的(de)弊端(duan)(duan)，同時改善了(le)齒(chi)(chi)面摩擦、磨損狀況(kuang)，降低(di)了(le)噪聲，維修周期長。星(xing)形(xing)彈(dan)性聯軸器(qi)(qi)外(wai)齒(chi)(chi)套齒(chi)(chi)端(duan)(duan)呈(cheng)喇(la)叭形(xing)狀，故(gu)不(bu)宜在高速和有(you)沖擊載荷情況(kuang)下(xia)使用(yong)(yong)，也不(bu)宜用(yong)(yong)于立(li)軸的(de)聯接。星(xing)型彈(dan)性聯軸器(qi)(qi)整體結(jie)構設計時，要充分注意齒(chi)(chi)面與滾子之間(jian)(jian)的(de)潤滑及(ji)防(fang)塵，還有(you)安(an)全防(fang)護作用(yong)(yong)。因為鏈條(tiao)萬一(yi)破斷，可(ke)能(neng)造成(cheng)人身事故(gu)。鼓(gu)度曲(qu)線曲(qu)率半徑與內(nei)齒(chi)(chi)單側減(jian)薄量(liang)成(cheng)正(zheng)比，即它(ta)與齒(chi)(chi)的(de)嚙合間(jian)(jian)隙有(you)關(guan)，使內(nei)、外(wai)齒(chi)(chi)裝拆十分方便。
