星(xing)形聯軸(zhou)器高速運轉時由于受離心力的(de)(de)作用而產生的(de)(de)徑向運動(dong)將(jiang)加速其磨(mo)損，加設(she)外殼。除了(le)能防塵存(cun)油外，減(jian)薄(bo)量不足(zu)可(ke)能會造(zao)成干涉，減(jian)薄(bo)量過大會削弱齒(chi)(chi)的(de)(de)強度，且會側隙很大。外齒(chi)(chi)的(de)(de)接(jie)觸條(tiao)件得到改善，避免了(le)在角位移條(tiao)件下直齒(chi)(chi)齒(chi)(chi)端棱邊擠壓，應力集中(zhong)的(de)(de)弊端，同(tong)時改善了(le)齒(chi)(chi)面(mian)摩(mo)擦、磨(mo)損狀(zhuang)況，降低了(le)噪聲，維修周期長(chang)。星(xing)形彈(dan)性聯軸(zhou)器外齒(chi)(chi)套齒(chi)(chi)端呈喇叭形狀(zhuang)，故不宜在高速和有沖擊(ji)載荷情況下使用，也不宜用于立軸(zhou)的(de)(de)聯接(jie)。星(xing)型彈(dan)性聯軸(zhou)器整(zheng)體結(jie)構設(she)計時，要充分注意(yi)齒(chi)(chi)面(mian)與滾子之(zhi)間(jian)的(de)(de)潤滑及防塵，還有安(an)全防護(hu)作用。因為鏈條(tiao)萬一(yi)破(po)斷，可(ke)能造(zao)成人身(shen)事故。鼓度曲線曲率半徑與內齒(chi)(chi)單(dan)側減(jian)薄(bo)量成正比(bi)，即它與齒(chi)(chi)的(de)(de)嚙合(he)間(jian)隙有關，使內、外齒(chi)(chi)裝拆十(shi)分方便。

星(xing)型聯(lian)(lian)(lian)(lian)(lian)軸(zhou)器有(you)(you)時被誤認為是梅(mei)花(hua)聯(lian)(lian)(lian)(lian)(lian)軸(zhou)器，他(ta)們安裝后的(de)外(wai)形幾乎相似(si)，但是同等(deng)型號下，星(xing)形聯(lian)(lian)(lian)(lian)(lian)軸(zhou)器承受(shou)的(de)扭力更大，相對梅(mei)花(hua)聯(lian)(lian)(lian)(lian)(lian)軸(zhou)器，它的(de)內孔(kong)和(he)外(wai)形可以做(zuo)到更小(xiao)。星(xing)形彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)聯(lian)(lian)(lian)(lian)(lian)軸(zhou)器聚氨脂彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)體由凸(tu)(tu)形爪(zhua)塊(kuai)限制(zhi)，聯(lian)(lian)(lian)(lian)(lian)軸(zhou)器是以工(gong)程(cheng)塑料(liao)(liao)作彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)元件，適(shi)用于(yu)聯(lian)(lian)(lian)(lian)(lian)接(jie)兩同軸(zhou)線的(de)傳(chuan)動軸(zhou)系，具有(you)(you)補償兩軸(zhou)相對偏移、緩(huan)沖、減震、耐磨性(xing)(xing)(xing)(xing)(xing)(xing)能，適(shi)應場合普遍 ，傳(chuan)遞轉矩20-35000.N.M,工(gong)作溫度(du)-35-+80攝氏(shi)度(du)。星(xing)型彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)聯(lian)(lian)(lian)(lian)(lian)軸(zhou)器中的(de)彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)元件是工(gong)程(cheng)塑料(liao)(liao)，由于(yu)該(gai)工(gong)程(cheng)塑料(liao)(liao)具有(you)(you)良好的(de)彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)、緩(huan)沖性(xing)(xing)(xing)(xing)(xing)(xing)、減震性(xing)(xing)(xing)(xing)(xing)(xing)、耐磨性(xing)(xing)(xing)(xing)(xing)(xing)，因此(ci)能很好的(de)補償兩傳(chuan)動軸(zhou)系之間的(de)各(ge)種(zhong)位移.星(xing)形彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)聯(lian)(lian)(lian)(lian)(lian)軸(zhou)器的(de)聚氨脂彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)(xing)體由凸(tu)(tu)形爪(zhua)塊(kuai)限制(zhi)。特點：預應力下無(wu)齒隙的(de)連(lian)接(jie)，用于(yu)主軸(zhou)傳(chuan)動、升降平臺和(he)機床(chuang)等(deng)。
