星(xing)形(xing)聯(lian)軸器(qi)(qi)高(gao)速運轉時由于受(shou)離心力(li)的作(zuo)用(yong)(yong)而產(chan)生的徑向運動將(jiang)加速其磨(mo)損，加設外殼。除了(le)能防(fang)塵存(cun)油(you)外，減(jian)薄(bo)量(liang)不(bu)(bu)足(zu)可能會(hui)(hui)造成干涉，減(jian)薄(bo)量(liang)過大會(hui)(hui)削(xue)弱(ruo)齒(chi)的強度，且會(hui)(hui)側隙(xi)很大。外齒(chi)的接觸條(tiao)(tiao)(tiao)件得到改(gai)善，避(bi)免了(le)在角位移條(tiao)(tiao)(tiao)件下直齒(chi)齒(chi)端(duan)棱邊(bian)擠(ji)壓，應力(li)集中的弊端(duan)，同時改(gai)善了(le)齒(chi)面(mian)摩擦、磨(mo)損狀況(kuang)，降低(di)了(le)噪(zao)聲(sheng)，維修周期長。星(xing)形(xing)彈性聯(lian)軸器(qi)(qi)外齒(chi)套齒(chi)端(duan)呈喇(la)叭形(xing)狀，故不(bu)(bu)宜在高(gao)速和(he)有沖擊載荷(he)情況(kuang)下使(shi)(shi)用(yong)(yong)，也不(bu)(bu)宜用(yong)(yong)于立軸的聯(lian)接。星(xing)型彈性聯(lian)軸器(qi)(qi)整(zheng)體(ti)結(jie)構設計時，要充分注意齒(chi)面(mian)與(yu)滾(gun)子之間的潤滑及防(fang)塵，還有安(an)全防(fang)護作(zuo)用(yong)(yong)。因為鏈條(tiao)(tiao)(tiao)萬一破斷，可能造成人身事故。鼓度曲線曲率(lv)半徑與(yu)內(nei)(nei)齒(chi)單側減(jian)薄(bo)量(liang)成正比，即它與(yu)齒(chi)的嚙合(he)間隙(xi)有關，使(shi)(shi)內(nei)(nei)、外齒(chi)裝拆十(shi)分方便。
