星(xing)形聯軸(zhou)器高速(su)運轉時(shi)(shi)由于受離心力(li)(li)的(de)(de)作(zuo)用(yong)(yong)而產生的(de)(de)徑向(xiang)運動將加速(su)其磨損，加設(she)外(wai)(wai)殼。除了(le)能防塵存油外(wai)(wai)，減薄(bo)量不足(zu)可能會造(zao)成(cheng)(cheng)干(gan)涉，減薄(bo)量過大(da)會削弱齒(chi)(chi)的(de)(de)強(qiang)度，且會側隙很大(da)。外(wai)(wai)齒(chi)(chi)的(de)(de)接觸條(tiao)(tiao)件得到改善，避免了(le)在角位移條(tiao)(tiao)件下直(zhi)齒(chi)(chi)齒(chi)(chi)端棱邊擠壓，應力(li)(li)集中的(de)(de)弊端，同時(shi)(shi)改善了(le)齒(chi)(chi)面(mian)摩擦、磨損狀況，降(jiang)低(di)了(le)噪聲，維修(xiu)周期長。星(xing)形彈(dan)性聯軸(zhou)器外(wai)(wai)齒(chi)(chi)套齒(chi)(chi)端呈喇(la)叭形狀，故(gu)不宜(yi)在高速(su)和有(you)沖擊載荷(he)情況下使用(yong)(yong)，也不宜(yi)用(yong)(yong)于立軸(zhou)的(de)(de)聯接。星(xing)型彈(dan)性聯軸(zhou)器整(zheng)體結構(gou)設(she)計時(shi)(shi)，要充分注意齒(chi)(chi)面(mian)與滾(gun)子之間(jian)(jian)的(de)(de)潤滑及(ji)防塵，還有(you)安全防護作(zuo)用(yong)(yong)。因為鏈條(tiao)(tiao)萬(wan)一(yi)破斷，可能造(zao)成(cheng)(cheng)人身事(shi)故(gu)。鼓度曲線曲率半徑與內齒(chi)(chi)單側減薄(bo)量成(cheng)(cheng)正比，即它與齒(chi)(chi)的(de)(de)嚙合間(jian)(jian)隙有(you)關，使內、外(wai)(wai)齒(chi)(chi)裝拆十分方便。

星(xing)型聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)有(you)(you)時(shi)被(bei)誤認為是(shi)(shi)梅花聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)，他們安(an)裝后的(de)(de)外形(xing)(xing)(xing)幾乎相(xiang)似，但(dan)是(shi)(shi)同等型號(hao)下(xia)，星(xing)形(xing)(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)承(cheng)受的(de)(de)扭力(li)更(geng)大，相(xiang)對梅花聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)，它(ta)的(de)(de)內(nei)孔和(he)外形(xing)(xing)(xing)可以(yi)做(zuo)到更(geng)小。星(xing)形(xing)(xing)(xing)彈(dan)性(xing)(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)聚氨脂彈(dan)性(xing)(xing)(xing)體(ti)(ti)由(you)凸形(xing)(xing)(xing)爪(zhua)塊限制(zhi)，聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)是(shi)(shi)以(yi)工(gong)程(cheng)(cheng)塑(su)料(liao)作彈(dan)性(xing)(xing)(xing)元件，適用于聯(lian)(lian)(lian)接兩(liang)同軸(zhou)(zhou)線的(de)(de)傳(chuan)動軸(zhou)(zhou)系(xi)，具有(you)(you)補(bu)償兩(liang)軸(zhou)(zhou)相(xiang)對偏移、緩沖(chong)、減(jian)震、耐磨(mo)性(xing)(xing)(xing)能(neng)，適應場合普遍 ，傳(chuan)遞(di)轉矩20-35000.N.M,工(gong)作溫度-35-+80攝(she)氏度。星(xing)型彈(dan)性(xing)(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)中的(de)(de)彈(dan)性(xing)(xing)(xing)元件是(shi)(shi)工(gong)程(cheng)(cheng)塑(su)料(liao)，由(you)于該(gai)工(gong)程(cheng)(cheng)塑(su)料(liao)具有(you)(you)良好(hao)的(de)(de)彈(dan)性(xing)(xing)(xing)、緩沖(chong)性(xing)(xing)(xing)、減(jian)震性(xing)(xing)(xing)、耐磨(mo)性(xing)(xing)(xing)，因(yin)此(ci)能(neng)很(hen)好(hao)的(de)(de)補(bu)償兩(liang)傳(chuan)動軸(zhou)(zhou)系(xi)之間的(de)(de)各(ge)種位移.星(xing)形(xing)(xing)(xing)彈(dan)性(xing)(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)的(de)(de)聚氨脂彈(dan)性(xing)(xing)(xing)體(ti)(ti)由(you)凸形(xing)(xing)(xing)爪(zhua)塊限制(zhi)。特點：預應力(li)下(xia)無齒隙的(de)(de)連接，用于主(zhu)軸(zhou)(zhou)傳(chuan)動、升降平臺和(he)機床等。
