星形聯(lian)軸器(qi)高速(su)(su)運轉(zhuan)時(shi)(shi)由于受(shou)離心力的(de)(de)(de)作用(yong)(yong)而產(chan)生的(de)(de)(de)徑向運動將加(jia)速(su)(su)其磨損(sun)，加(jia)設(she)外(wai)殼(ke)。除了能(neng)防塵存油外(wai)，減(jian)薄(bo)量(liang)不(bu)足可能(neng)會造成干涉，減(jian)薄(bo)量(liang)過大(da)(da)會削弱齒(chi)的(de)(de)(de)強度(du)，且會側隙很大(da)(da)。外(wai)齒(chi)的(de)(de)(de)接(jie)觸條件(jian)得到(dao)改(gai)善，避免(mian)了在角位移條件(jian)下直齒(chi)齒(chi)端(duan)棱邊擠壓，應力集(ji)中的(de)(de)(de)弊端(duan)，同時(shi)(shi)改(gai)善了齒(chi)面摩擦、磨損(sun)狀況，降(jiang)低(di)了噪聲，維修周期長(chang)。星形彈性聯(lian)軸器(qi)外(wai)齒(chi)套齒(chi)端(duan)呈喇叭形狀，故不(bu)宜在高速(su)(su)和有沖擊載荷(he)情況下使用(yong)(yong)，也不(bu)宜用(yong)(yong)于立(li)軸的(de)(de)(de)聯(lian)接(jie)。星型彈性聯(lian)軸器(qi)整體(ti)結構設(she)計時(shi)(shi)，要充分(fen)注(zhu)意(yi)齒(chi)面與滾子之間(jian)的(de)(de)(de)潤滑及(ji)防塵，還(huan)有安全防護作用(yong)(yong)。因為鏈條萬一破斷，可能(neng)造成人(ren)身事故。鼓度(du)曲(qu)線曲(qu)率半徑與內齒(chi)單側減(jian)薄(bo)量(liang)成正比(bi)，即它與齒(chi)的(de)(de)(de)嚙合(he)間(jian)隙有關(guan)，使內、外(wai)齒(chi)裝拆十分(fen)方(fang)便。
