星形聯(lian)軸器高速運轉時由(you)于受離心(xin)力的(de)作(zuo)(zuo)用(yong)而(er)產生的(de)徑向運動將(jiang)加速其磨(mo)(mo)損，加設(she)外殼。除了能防(fang)塵(chen)存油(you)外，減薄(bo)(bo)量(liang)不(bu)(bu)足可能會造成干(gan)涉，減薄(bo)(bo)量(liang)過大會削弱齒(chi)(chi)(chi)(chi)的(de)強(qiang)度(du)，且會側(ce)隙很大。外齒(chi)(chi)(chi)(chi)的(de)接觸條(tiao)(tiao)件得到改善，避免(mian)了在(zai)角位移條(tiao)(tiao)件下(xia)直齒(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)端(duan)棱邊(bian)擠壓，應力集中(zhong)的(de)弊端(duan)，同時改善了齒(chi)(chi)(chi)(chi)面摩擦、磨(mo)(mo)損狀況，降低了噪(zao)聲，維修周期長(chang)。星形彈性聯(lian)軸器外齒(chi)(chi)(chi)(chi)套齒(chi)(chi)(chi)(chi)端(duan)呈喇(la)叭形狀，故不(bu)(bu)宜在(zai)高速和(he)有沖(chong)擊(ji)載荷情況下(xia)使(shi)用(yong)，也(ye)不(bu)(bu)宜用(yong)于立(li)軸的(de)聯(lian)接。星型彈性聯(lian)軸器整(zheng)體結構設(she)計時，要充(chong)分注意(yi)齒(chi)(chi)(chi)(chi)面與(yu)滾子之間(jian)(jian)的(de)潤滑(hua)及(ji)防(fang)塵(chen)，還有安全(quan)防(fang)護作(zuo)(zuo)用(yong)。因為鏈條(tiao)(tiao)萬一(yi)破斷，可能造成人身事故。鼓(gu)度(du)曲線曲率半(ban)徑與(yu)內(nei)齒(chi)(chi)(chi)(chi)單側(ce)減薄(bo)(bo)量(liang)成正比，即它與(yu)齒(chi)(chi)(chi)(chi)的(de)嚙合間(jian)(jian)隙有關，使(shi)內(nei)、外齒(chi)(chi)(chi)(chi)裝拆(chai)十分方便。
