星(xing)形(xing)聯(lian)軸(zhou)(zhou)(zhou)器(qi)高速運(yun)轉時(shi)由于(yu)受離心力(li)的(de)作用而產(chan)生的(de)徑向(xiang)運(yun)動將加速其磨損(sun)，加設外(wai)(wai)(wai)殼。除了(le)能防塵存(cun)油外(wai)(wai)(wai)，減薄量(liang)不(bu)(bu)足可能會(hui)造成干涉，減薄量(liang)過大會(hui)削弱齒(chi)(chi)的(de)強度，且會(hui)側隙很大。外(wai)(wai)(wai)齒(chi)(chi)的(de)接觸條件(jian)得到改(gai)善，避免了(le)在(zai)角位移條件(jian)下直齒(chi)(chi)齒(chi)(chi)端(duan)棱邊擠壓，應(ying)力(li)集中的(de)弊端(duan)，同時(shi)改(gai)善了(le)齒(chi)(chi)面摩擦、磨損(sun)狀(zhuang)況(kuang)，降(jiang)低了(le)噪聲，維修周(zhou)期(qi)長。星(xing)形(xing)彈性聯(lian)軸(zhou)(zhou)(zhou)器(qi)外(wai)(wai)(wai)齒(chi)(chi)套齒(chi)(chi)端(duan)呈喇叭形(xing)狀(zhuang)，故不(bu)(bu)宜在(zai)高速和(he)有(you)沖擊載荷情況(kuang)下使用，也不(bu)(bu)宜用于(yu)立軸(zhou)(zhou)(zhou)的(de)聯(lian)接。星(xing)型彈性聯(lian)軸(zhou)(zhou)(zhou)器(qi)整體(ti)結構設計時(shi)，要充分注意(yi)齒(chi)(chi)面與滾(gun)子之間(jian)的(de)潤滑及防塵，還(huan)有(you)安(an)全防護作用。因(yin)為(wei)鏈條萬(wan)一(yi)破斷，可能造成人身事(shi)故。鼓度曲(qu)(qu)線曲(qu)(qu)率(lv)半(ban)徑與內齒(chi)(chi)單(dan)側減薄量(liang)成正比，即它與齒(chi)(chi)的(de)嚙合間(jian)隙有(you)關，使內、外(wai)(wai)(wai)齒(chi)(chi)裝拆十分方便(bian)。
