星(xing)形(xing)聯(lian)(lian)軸器高(gao)速(su)(su)運轉時由于(yu)受離心力的(de)(de)(de)作(zuo)用(yong)而產(chan)生的(de)(de)(de)徑向運動(dong)將加速(su)(su)其磨損(sun)，加設外(wai)(wai)殼。除了能(neng)防塵(chen)存油外(wai)(wai)，減薄(bo)量(liang)不(bu)(bu)足(zu)可能(neng)會造成(cheng)干(gan)涉(she)，減薄(bo)量(liang)過(guo)大會削弱齒(chi)(chi)(chi)(chi)的(de)(de)(de)強度，且會側隙很大。外(wai)(wai)齒(chi)(chi)(chi)(chi)的(de)(de)(de)接(jie)觸條(tiao)件得到改善(shan)(shan)，避(bi)免了在角位移(yi)條(tiao)件下直齒(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)端(duan)棱邊(bian)擠壓，應力集中的(de)(de)(de)弊端(duan)，同時改善(shan)(shan)了齒(chi)(chi)(chi)(chi)面(mian)摩(mo)擦、磨損(sun)狀(zhuang)況(kuang)，降(jiang)低了噪聲，維修周期長。星(xing)形(xing)彈性聯(lian)(lian)軸器外(wai)(wai)齒(chi)(chi)(chi)(chi)套齒(chi)(chi)(chi)(chi)端(duan)呈喇叭形(xing)狀(zhuang)，故(gu)不(bu)(bu)宜在高(gao)速(su)(su)和有沖擊(ji)載荷情況(kuang)下使用(yong)，也不(bu)(bu)宜用(yong)于(yu)立軸的(de)(de)(de)聯(lian)(lian)接(jie)。星(xing)型彈性聯(lian)(lian)軸器整體結構設計時，要充分(fen)注(zhu)意齒(chi)(chi)(chi)(chi)面(mian)與滾子之(zhi)間的(de)(de)(de)潤滑(hua)及防塵(chen)，還有安(an)全防護作(zuo)用(yong)。因(yin)為鏈條(tiao)萬一破(po)斷(duan)，可能(neng)造成(cheng)人身事故(gu)。鼓度曲線曲率半徑與內齒(chi)(chi)(chi)(chi)單側減薄(bo)量(liang)成(cheng)正比(bi)，即它與齒(chi)(chi)(chi)(chi)的(de)(de)(de)嚙合間隙有關，使內、外(wai)(wai)齒(chi)(chi)(chi)(chi)裝拆十分(fen)方便。

星(xing)型聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)有時被誤認為(wei)是梅花聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)，他們安裝后(hou)的(de)(de)(de)外形(xing)(xing)幾(ji)乎相(xiang)似，但是同等(deng)(deng)型號下，星(xing)形(xing)(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)承受的(de)(de)(de)扭力(li)更大，相(xiang)對梅花聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)，它(ta)的(de)(de)(de)內孔和外形(xing)(xing)可以(yi)做到更小。星(xing)形(xing)(xing)彈(dan)(dan)(dan)(dan)性(xing)(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)聚氨脂(zhi)彈(dan)(dan)(dan)(dan)性(xing)(xing)體由(you)(you)凸形(xing)(xing)爪塊(kuai)(kuai)限(xian)制，聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)是以(yi)工程塑料(liao)作(zuo)彈(dan)(dan)(dan)(dan)性(xing)(xing)元件，適(shi)用(yong)于聯(lian)(lian)接(jie)兩(liang)同軸(zhou)線的(de)(de)(de)傳動(dong)軸(zhou)系，具有補償兩(liang)軸(zhou)相(xiang)對偏移、緩(huan)沖(chong)、減(jian)震、耐磨(mo)(mo)性(xing)(xing)能，適(shi)應場合(he)普(pu)遍 ，傳遞轉矩(ju)20-35000.N.M,工作(zuo)溫度-35-+80攝氏(shi)度。星(xing)型彈(dan)(dan)(dan)(dan)性(xing)(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)中的(de)(de)(de)彈(dan)(dan)(dan)(dan)性(xing)(xing)元件是工程塑料(liao)，由(you)(you)于該工程塑料(liao)具有良好(hao)的(de)(de)(de)彈(dan)(dan)(dan)(dan)性(xing)(xing)、緩(huan)沖(chong)性(xing)(xing)、減(jian)震性(xing)(xing)、耐磨(mo)(mo)性(xing)(xing)，因此能很好(hao)的(de)(de)(de)補償兩(liang)傳動(dong)軸(zhou)系之間的(de)(de)(de)各(ge)種(zhong)位移.星(xing)形(xing)(xing)彈(dan)(dan)(dan)(dan)性(xing)(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)的(de)(de)(de)聚氨脂(zhi)彈(dan)(dan)(dan)(dan)性(xing)(xing)體由(you)(you)凸形(xing)(xing)爪塊(kuai)(kuai)限(xian)制。特點：預應力(li)下無齒隙的(de)(de)(de)連(lian)接(jie)，用(yong)于主(zhu)軸(zhou)傳動(dong)、升降平臺和機(ji)床(chuang)等(deng)(deng)。
