星(xing)形聯(lian)軸(zhou)(zhou)器高(gao)速(su)運轉時由于受(shou)離心力(li)的(de)(de)作用(yong)(yong)(yong)而(er)產生的(de)(de)徑(jing)向運動將加(jia)速(su)其磨損(sun)，加(jia)設外殼(ke)。除了能防塵存(cun)油外，減薄量(liang)不(bu)足可(ke)能會造成干涉，減薄量(liang)過大會削弱齒(chi)(chi)(chi)(chi)的(de)(de)強度，且(qie)會側隙很大。外齒(chi)(chi)(chi)(chi)的(de)(de)接觸條(tiao)件得(de)到改善(shan)，避免了在(zai)角位移條(tiao)件下直齒(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)端(duan)(duan)棱邊擠壓，應力(li)集中的(de)(de)弊端(duan)(duan)，同時改善(shan)了齒(chi)(chi)(chi)(chi)面(mian)摩擦、磨損(sun)狀(zhuang)況(kuang)，降(jiang)低了噪聲，維修周期長。星(xing)形彈性聯(lian)軸(zhou)(zhou)器外齒(chi)(chi)(chi)(chi)套齒(chi)(chi)(chi)(chi)端(duan)(duan)呈喇叭形狀(zhuang)，故(gu)不(bu)宜在(zai)高(gao)速(su)和有(you)沖(chong)擊載荷(he)情況(kuang)下使(shi)用(yong)(yong)(yong)，也不(bu)宜用(yong)(yong)(yong)于立軸(zhou)(zhou)的(de)(de)聯(lian)接。星(xing)型彈性聯(lian)軸(zhou)(zhou)器整體(ti)結構設計時，要充(chong)分注(zhu)意齒(chi)(chi)(chi)(chi)面(mian)與(yu)(yu)滾(gun)子之間(jian)的(de)(de)潤滑(hua)及防塵，還(huan)有(you)安全防護(hu)作用(yong)(yong)(yong)。因(yin)為鏈條(tiao)萬一破(po)斷，可(ke)能造成人身事(shi)故(gu)。鼓度曲線曲率半徑(jing)與(yu)(yu)內齒(chi)(chi)(chi)(chi)單側減薄量(liang)成正比，即它與(yu)(yu)齒(chi)(chi)(chi)(chi)的(de)(de)嚙(nie)合(he)間(jian)隙有(you)關，使(shi)內、外齒(chi)(chi)(chi)(chi)裝拆(chai)十分方便。

星(xing)(xing)型(xing)(xing)聯(lian)(lian)軸(zhou)器有時被誤認(ren)為是梅花聯(lian)(lian)軸(zhou)器，他們安裝后的(de)(de)(de)外形(xing)幾(ji)乎(hu)相(xiang)似，但是同(tong)等型(xing)(xing)號下，星(xing)(xing)形(xing)聯(lian)(lian)軸(zhou)器承受(shou)的(de)(de)(de)扭力(li)更(geng)大，相(xiang)對梅花聯(lian)(lian)軸(zhou)器，它的(de)(de)(de)內孔和外形(xing)可以(yi)做到(dao)更(geng)小。星(xing)(xing)形(xing)彈(dan)(dan)(dan)性(xing)(xing)聯(lian)(lian)軸(zhou)器聚(ju)(ju)氨脂(zhi)彈(dan)(dan)(dan)性(xing)(xing)體(ti)由凸形(xing)爪塊限(xian)制，聯(lian)(lian)軸(zhou)器是以(yi)工程(cheng)塑料(liao)(liao)作(zuo)彈(dan)(dan)(dan)性(xing)(xing)元件(jian)，適用于聯(lian)(lian)接(jie)兩同(tong)軸(zhou)線的(de)(de)(de)傳(chuan)(chuan)動(dong)軸(zhou)系，具有補(bu)償兩軸(zhou)相(xiang)對偏移、緩(huan)沖(chong)、減震(zhen)、耐(nai)磨性(xing)(xing)能(neng)(neng)，適應場(chang)合普遍(bian) ，傳(chuan)(chuan)遞轉矩20-35000.N.M,工作(zuo)溫度-35-+80攝氏度。星(xing)(xing)型(xing)(xing)彈(dan)(dan)(dan)性(xing)(xing)聯(lian)(lian)軸(zhou)器中的(de)(de)(de)彈(dan)(dan)(dan)性(xing)(xing)元件(jian)是工程(cheng)塑料(liao)(liao)，由于該工程(cheng)塑料(liao)(liao)具有良(liang)好的(de)(de)(de)彈(dan)(dan)(dan)性(xing)(xing)、緩(huan)沖(chong)性(xing)(xing)、減震(zhen)性(xing)(xing)、耐(nai)磨性(xing)(xing)，因此能(neng)(neng)很好的(de)(de)(de)補(bu)償兩傳(chuan)(chuan)動(dong)軸(zhou)系之間的(de)(de)(de)各種位移.星(xing)(xing)形(xing)彈(dan)(dan)(dan)性(xing)(xing)聯(lian)(lian)軸(zhou)器的(de)(de)(de)聚(ju)(ju)氨脂(zhi)彈(dan)(dan)(dan)性(xing)(xing)體(ti)由凸形(xing)爪塊限(xian)制。特點：預應力(li)下無齒(chi)隙的(de)(de)(de)連接(jie)，用于主軸(zhou)傳(chuan)(chuan)動(dong)、升(sheng)降平臺和機床等。
