星(xing)(xing)形聯(lian)軸(zhou)器高速運轉時由(you)于受離心(xin)力(li)的(de)作(zuo)用而產生的(de)徑向運動將加速其磨損，加設外(wai)殼。除了能(neng)防(fang)(fang)塵存油外(wai)，減薄(bo)量不(bu)足可能(neng)會(hui)造成(cheng)干(gan)涉，減薄(bo)量過(guo)大會(hui)削弱齒(chi)(chi)(chi)(chi)(chi)的(de)強度(du)(du)，且(qie)會(hui)側(ce)隙很(hen)大。外(wai)齒(chi)(chi)(chi)(chi)(chi)的(de)接(jie)觸條(tiao)件(jian)得到(dao)改善，避免了在角位移條(tiao)件(jian)下直齒(chi)(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)(chi)端棱邊擠壓，應力(li)集中的(de)弊端，同時改善了齒(chi)(chi)(chi)(chi)(chi)面摩擦、磨損狀況(kuang)，降低了噪聲，維修周(zhou)期長。星(xing)(xing)形彈性聯(lian)軸(zhou)器外(wai)齒(chi)(chi)(chi)(chi)(chi)套齒(chi)(chi)(chi)(chi)(chi)端呈喇叭形狀，故不(bu)宜(yi)在高速和有(you)沖擊(ji)載荷(he)情況(kuang)下使用，也(ye)不(bu)宜(yi)用于立軸(zhou)的(de)聯(lian)接(jie)。星(xing)(xing)型彈性聯(lian)軸(zhou)器整體結(jie)構(gou)設計時，要(yao)充分注意齒(chi)(chi)(chi)(chi)(chi)面與滾子之間的(de)潤滑及防(fang)(fang)塵，還有(you)安全(quan)防(fang)(fang)護作(zuo)用。因為鏈條(tiao)萬一(yi)破(po)斷，可能(neng)造成(cheng)人身事故。鼓度(du)(du)曲(qu)線曲(qu)率半徑與內齒(chi)(chi)(chi)(chi)(chi)單側(ce)減薄(bo)量成(cheng)正(zheng)比，即它(ta)與齒(chi)(chi)(chi)(chi)(chi)的(de)嚙合間隙有(you)關(guan)，使內、外(wai)齒(chi)(chi)(chi)(chi)(chi)裝拆十分方(fang)便。

星型聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)有時被(bei)誤(wu)認為是梅花聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)，他們安裝后的(de)(de)外(wai)形(xing)(xing)幾乎相似，但是同(tong)(tong)等型號下，星形(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)承受的(de)(de)扭力更大，相對梅花聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)，它的(de)(de)內孔和外(wai)形(xing)(xing)可以做到更小。星形(xing)(xing)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)聚氨脂彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)體(ti)由凸(tu)形(xing)(xing)爪塊(kuai)限制，聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)是以工(gong)程塑(su)料作彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)元件(jian)，適用于聯(lian)(lian)(lian)接兩(liang)同(tong)(tong)軸(zhou)(zhou)線的(de)(de)傳(chuan)動(dong)軸(zhou)(zhou)系，具(ju)(ju)有補償(chang)兩(liang)軸(zhou)(zhou)相對偏移(yi)、緩沖、減震、耐(nai)磨(mo)性(xing)(xing)(xing)(xing)能(neng)(neng)，適應場合普(pu)遍 ，傳(chuan)遞轉矩(ju)20-35000.N.M,工(gong)作溫度(du)-35-+80攝氏(shi)度(du)。星型彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)中的(de)(de)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)元件(jian)是工(gong)程塑(su)料，由于該工(gong)程塑(su)料具(ju)(ju)有良(liang)好的(de)(de)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)、緩沖性(xing)(xing)(xing)(xing)、減震性(xing)(xing)(xing)(xing)、耐(nai)磨(mo)性(xing)(xing)(xing)(xing)，因(yin)此能(neng)(neng)很好的(de)(de)補償(chang)兩(liang)傳(chuan)動(dong)軸(zhou)(zhou)系之間的(de)(de)各種位移(yi).星形(xing)(xing)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)的(de)(de)聚氨脂彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)體(ti)由凸(tu)形(xing)(xing)爪塊(kuai)限制。特點：預(yu)應力下無齒(chi)隙的(de)(de)連(lian)接，用于主軸(zhou)(zhou)傳(chuan)動(dong)、升降平臺和機床(chuang)等。
