星(xing)形聯軸器高(gao)速運轉時由于受(shou)離心力的(de)(de)(de)作用而產生(sheng)的(de)(de)(de)徑向運動將加(jia)速其磨(mo)(mo)損(sun)，加(jia)設(she)外(wai)(wai)殼。除了(le)(le)能防塵存(cun)油外(wai)(wai)，減(jian)(jian)薄量不(bu)足可能會造(zao)成干涉(she)，減(jian)(jian)薄量過(guo)大會削弱(ruo)齒(chi)(chi)的(de)(de)(de)強度，且會側隙很大。外(wai)(wai)齒(chi)(chi)的(de)(de)(de)接觸條(tiao)件得到改善(shan)，避免了(le)(le)在角位移條(tiao)件下直(zhi)齒(chi)(chi)齒(chi)(chi)端棱邊(bian)擠壓，應力集中的(de)(de)(de)弊端，同(tong)時改善(shan)了(le)(le)齒(chi)(chi)面(mian)摩擦、磨(mo)(mo)損(sun)狀(zhuang)況(kuang)，降低(di)了(le)(le)噪聲，維(wei)修周期長。星(xing)形彈(dan)性(xing)聯軸器外(wai)(wai)齒(chi)(chi)套齒(chi)(chi)端呈喇叭形狀(zhuang)，故不(bu)宜在高(gao)速和有(you)沖擊載荷情(qing)況(kuang)下使用，也(ye)不(bu)宜用于立軸的(de)(de)(de)聯接。星(xing)型彈(dan)性(xing)聯軸器整體結構(gou)設(she)計(ji)時，要(yao)充(chong)分注意齒(chi)(chi)面(mian)與滾子之間的(de)(de)(de)潤滑(hua)及(ji)防塵，還有(you)安全防護作用。因為鏈(lian)條(tiao)萬一破斷，可能造(zao)成人身事(shi)故。鼓(gu)度曲線(xian)曲率半徑與內齒(chi)(chi)單側減(jian)(jian)薄量成正(zheng)比，即它與齒(chi)(chi)的(de)(de)(de)嚙合(he)間隙有(you)關，使內、外(wai)(wai)齒(chi)(chi)裝拆十(shi)分方便。
