星形聯(lian)(lian)軸(zhou)(zhou)器(qi)高(gao)速(su)運轉時由于受(shou)離(li)心力的(de)(de)(de)作(zuo)用而產生(sheng)的(de)(de)(de)徑向運動將加速(su)其磨損，加設外(wai)殼。除了(le)(le)能(neng)防塵存(cun)油(you)外(wai)，減薄(bo)(bo)量(liang)不足可(ke)能(neng)會(hui)造成(cheng)(cheng)干涉，減薄(bo)(bo)量(liang)過大會(hui)削(xue)弱齒(chi)(chi)的(de)(de)(de)強度，且(qie)會(hui)側(ce)隙(xi)很大。外(wai)齒(chi)(chi)的(de)(de)(de)接(jie)觸條(tiao)(tiao)件得到改善(shan)，避免了(le)(le)在角位移條(tiao)(tiao)件下直齒(chi)(chi)齒(chi)(chi)端(duan)(duan)棱(leng)邊擠壓，應力集中的(de)(de)(de)弊端(duan)(duan)，同時改善(shan)了(le)(le)齒(chi)(chi)面(mian)摩擦、磨損狀況(kuang)，降(jiang)低了(le)(le)噪聲，維修周期長(chang)。星形彈性聯(lian)(lian)軸(zhou)(zhou)器(qi)外(wai)齒(chi)(chi)套齒(chi)(chi)端(duan)(duan)呈(cheng)喇叭形狀，故不宜在高(gao)速(su)和(he)有(you)沖擊載荷情(qing)況(kuang)下使用，也不宜用于立軸(zhou)(zhou)的(de)(de)(de)聯(lian)(lian)接(jie)。星型(xing)彈性聯(lian)(lian)軸(zhou)(zhou)器(qi)整體結構設計(ji)時，要充分(fen)注(zhu)意齒(chi)(chi)面(mian)與滾子之間的(de)(de)(de)潤(run)滑及(ji)防塵，還有(you)安全防護作(zuo)用。因為鏈條(tiao)(tiao)萬一破斷，可(ke)能(neng)造成(cheng)(cheng)人身事故。鼓度曲(qu)線(xian)曲(qu)率半徑與內齒(chi)(chi)單(dan)側(ce)減薄(bo)(bo)量(liang)成(cheng)(cheng)正比，即它與齒(chi)(chi)的(de)(de)(de)嚙合間隙(xi)有(you)關，使內、外(wai)齒(chi)(chi)裝拆十分(fen)方便。

星型(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器有時被(bei)誤認為是(shi)(shi)梅花聯(lian)(lian)(lian)軸(zhou)(zhou)器，他們安裝后的(de)(de)外形(xing)(xing)幾(ji)乎(hu)相似，但(dan)是(shi)(shi)同(tong)等(deng)型(xing)(xing)號下(xia)，星形(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器承受的(de)(de)扭力更大(da)，相對梅花聯(lian)(lian)(lian)軸(zhou)(zhou)器，它的(de)(de)內孔和(he)外形(xing)(xing)可以做到更小。星形(xing)(xing)彈(dan)性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器聚(ju)氨脂彈(dan)性(xing)(xing)體由(you)凸(tu)形(xing)(xing)爪塊限(xian)制，聯(lian)(lian)(lian)軸(zhou)(zhou)器是(shi)(shi)以工(gong)(gong)程塑料(liao)作(zuo)彈(dan)性(xing)(xing)元(yuan)件，適(shi)用于聯(lian)(lian)(lian)接(jie)兩(liang)同(tong)軸(zhou)(zhou)線的(de)(de)傳(chuan)動(dong)軸(zhou)(zhou)系，具有補償兩(liang)軸(zhou)(zhou)相對偏移、緩(huan)沖(chong)、減震(zhen)、耐磨性(xing)(xing)能，適(shi)應場合普遍 ，傳(chuan)遞(di)轉矩20-35000.N.M,工(gong)(gong)作(zuo)溫度(du)(du)-35-+80攝氏度(du)(du)。星型(xing)(xing)彈(dan)性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器中的(de)(de)彈(dan)性(xing)(xing)元(yuan)件是(shi)(shi)工(gong)(gong)程塑料(liao)，由(you)于該(gai)工(gong)(gong)程塑料(liao)具有良好的(de)(de)彈(dan)性(xing)(xing)、緩(huan)沖(chong)性(xing)(xing)、減震(zhen)性(xing)(xing)、耐磨性(xing)(xing)，因此能很好的(de)(de)補償兩(liang)傳(chuan)動(dong)軸(zhou)(zhou)系之間的(de)(de)各(ge)種位移.星形(xing)(xing)彈(dan)性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器的(de)(de)聚(ju)氨脂彈(dan)性(xing)(xing)體由(you)凸(tu)形(xing)(xing)爪塊限(xian)制。特點：預應力下(xia)無(wu)齒隙的(de)(de)連(lian)接(jie)，用于主軸(zhou)(zhou)傳(chuan)動(dong)、升降平臺和(he)機床等(deng)。
