星(xing)(xing)(xing)形(xing)聯(lian)軸器高(gao)速(su)運轉時(shi)由于(yu)受離(li)心力的(de)(de)作用(yong)而產生(sheng)的(de)(de)徑(jing)向運動將加速(su)其磨損(sun)，加設外(wai)(wai)殼。除了(le)(le)能防(fang)(fang)塵存油外(wai)(wai)，減薄(bo)量(liang)(liang)不足可能會造成干(gan)涉，減薄(bo)量(liang)(liang)過大會削弱(ruo)齒(chi)(chi)(chi)的(de)(de)強(qiang)度，且會側(ce)隙(xi)很大。外(wai)(wai)齒(chi)(chi)(chi)的(de)(de)接觸條件得到改善，避免了(le)(le)在(zai)角位(wei)移條件下(xia)直齒(chi)(chi)(chi)齒(chi)(chi)(chi)端棱(leng)邊擠壓，應力集中(zhong)的(de)(de)弊端，同時(shi)改善了(le)(le)齒(chi)(chi)(chi)面摩(mo)擦、磨損(sun)狀況(kuang)，降(jiang)低了(le)(le)噪聲(sheng)，維修周期長。星(xing)(xing)(xing)形(xing)彈(dan)性(xing)聯(lian)軸器外(wai)(wai)齒(chi)(chi)(chi)套齒(chi)(chi)(chi)端呈喇叭形(xing)狀，故不宜在(zai)高(gao)速(su)和有(you)沖擊載(zai)荷情況(kuang)下(xia)使用(yong)，也不宜用(yong)于(yu)立(li)軸的(de)(de)聯(lian)接。星(xing)(xing)(xing)型(xing)彈(dan)性(xing)聯(lian)軸器整體(ti)結(jie)構(gou)設計時(shi)，要充分(fen)注意齒(chi)(chi)(chi)面與滾(gun)子之間(jian)的(de)(de)潤滑(hua)及(ji)防(fang)(fang)塵，還有(you)安全防(fang)(fang)護(hu)作用(yong)。因為鏈(lian)條萬(wan)一破斷，可能造成人身事故。鼓(gu)度曲線曲率半徑(jing)與內齒(chi)(chi)(chi)單側(ce)減薄(bo)量(liang)(liang)成正比，即它與齒(chi)(chi)(chi)的(de)(de)嚙合(he)間(jian)隙(xi)有(you)關，使內、外(wai)(wai)齒(chi)(chi)(chi)裝拆十分(fen)方便。
