星形聯(lian)軸器(qi)(qi)高(gao)速運轉時由于受(shou)離心力的(de)(de)作用而產生的(de)(de)徑向(xiang)運動將加(jia)速其磨(mo)損，加(jia)設(she)外(wai)(wai)殼。除了(le)能防(fang)塵(chen)存(cun)油外(wai)(wai)，減薄量不足可(ke)能會(hui)造成(cheng)(cheng)干(gan)涉，減薄量過大(da)(da)會(hui)削弱齒(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)強度，且會(hui)側隙很(hen)大(da)(da)。外(wai)(wai)齒(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)接(jie)觸條件得到改善，避免了(le)在角位移(yi)條件下直(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)(chi)(chi)端棱邊擠壓，應力集中的(de)(de)弊端，同時改善了(le)齒(chi)(chi)(chi)(chi)(chi)(chi)面摩擦、磨(mo)損狀況(kuang)，降低了(le)噪聲(sheng)，維修周期長(chang)。星形彈(dan)性(xing)聯(lian)軸器(qi)(qi)外(wai)(wai)齒(chi)(chi)(chi)(chi)(chi)(chi)套齒(chi)(chi)(chi)(chi)(chi)(chi)端呈喇(la)叭形狀，故不宜在高(gao)速和(he)有(you)(you)沖擊載(zai)荷情況(kuang)下使用，也不宜用于立(li)軸的(de)(de)聯(lian)接(jie)。星型彈(dan)性(xing)聯(lian)軸器(qi)(qi)整體結構設(she)計(ji)時，要充(chong)分注(zhu)意齒(chi)(chi)(chi)(chi)(chi)(chi)面與滾子之間(jian)的(de)(de)潤滑及防(fang)塵(chen)，還有(you)(you)安全防(fang)護作用。因為鏈(lian)條萬一破斷，可(ke)能造成(cheng)(cheng)人身事故。鼓度曲(qu)線曲(qu)率半徑與內齒(chi)(chi)(chi)(chi)(chi)(chi)單(dan)側減薄量成(cheng)(cheng)正(zheng)比，即它與齒(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)嚙合間(jian)隙有(you)(you)關，使內、外(wai)(wai)齒(chi)(chi)(chi)(chi)(chi)(chi)裝拆十(shi)分方便。
