星形(xing)(xing)(xing)聯(lian)(lian)軸(zhou)器高速運轉時(shi)由(you)于(yu)受離心(xin)力的(de)(de)作用而產(chan)生的(de)(de)徑向運動將加速其(qi)磨(mo)損，加設外(wai)殼。除了(le)能(neng)防塵(chen)存油外(wai)，減薄(bo)(bo)量不(bu)足可(ke)能(neng)會造(zao)成干涉，減薄(bo)(bo)量過大會削(xue)弱齒(chi)(chi)(chi)(chi)的(de)(de)強度，且會側(ce)隙很大。外(wai)齒(chi)(chi)(chi)(chi)的(de)(de)接觸條(tiao)件得到改(gai)善，避免了(le)在角位移條(tiao)件下直齒(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)端棱邊擠壓，應(ying)力集中(zhong)的(de)(de)弊端，同時(shi)改(gai)善了(le)齒(chi)(chi)(chi)(chi)面(mian)摩擦、磨(mo)損狀況，降低了(le)噪聲，維(wei)修周期長。星形(xing)(xing)(xing)彈性聯(lian)(lian)軸(zhou)器外(wai)齒(chi)(chi)(chi)(chi)套齒(chi)(chi)(chi)(chi)端呈喇叭形(xing)(xing)(xing)狀，故不(bu)宜在高速和有沖擊(ji)載荷情況下使用，也不(bu)宜用于(yu)立軸(zhou)的(de)(de)聯(lian)(lian)接。星型彈性聯(lian)(lian)軸(zhou)器整體結構設計時(shi)，要充分注意齒(chi)(chi)(chi)(chi)面(mian)與滾(gun)子之間(jian)的(de)(de)潤滑及防塵(chen)，還(huan)有安全防護作用。因為鏈條(tiao)萬(wan)一破斷，可(ke)能(neng)造(zao)成人身事故。鼓度曲線曲率(lv)半徑與內(nei)齒(chi)(chi)(chi)(chi)單(dan)側(ce)減薄(bo)(bo)量成正比，即它(ta)與齒(chi)(chi)(chi)(chi)的(de)(de)嚙(nie)合間(jian)隙有關，使內(nei)、外(wai)齒(chi)(chi)(chi)(chi)裝(zhuang)拆十(shi)分方便。

星型(xing)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)有時被誤認(ren)為是梅花聯軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)，他們安裝后的外(wai)(wai)形幾乎相似，但是同等(deng)型(xing)號下，星形聯軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)承受的扭(niu)力更大，相對(dui)梅花聯軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)，它的內孔(kong)和(he)外(wai)(wai)形可(ke)以做到(dao)更小(xiao)。星形彈(dan)(dan)性(xing)(xing)(xing)(xing)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)聚氨脂(zhi)彈(dan)(dan)性(xing)(xing)(xing)(xing)體由凸(tu)形爪塊限(xian)制，聯軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)是以工(gong)程塑料作彈(dan)(dan)性(xing)(xing)(xing)(xing)元件(jian)，適用(yong)(yong)于(yu)聯接(jie)兩(liang)同軸(zhou)(zhou)(zhou)(zhou)線(xian)的傳(chuan)動軸(zhou)(zhou)(zhou)(zhou)系(xi)，具(ju)(ju)有補償兩(liang)軸(zhou)(zhou)(zhou)(zhou)相對(dui)偏(pian)移(yi)、緩(huan)(huan)沖、減震(zhen)、耐(nai)(nai)磨性(xing)(xing)(xing)(xing)能，適應場合普遍 ，傳(chuan)遞轉矩20-35000.N.M,工(gong)作溫(wen)度-35-+80攝氏(shi)度。星型(xing)彈(dan)(dan)性(xing)(xing)(xing)(xing)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)中(zhong)的彈(dan)(dan)性(xing)(xing)(xing)(xing)元件(jian)是工(gong)程塑料，由于(yu)該工(gong)程塑料具(ju)(ju)有良好(hao)(hao)的彈(dan)(dan)性(xing)(xing)(xing)(xing)、緩(huan)(huan)沖性(xing)(xing)(xing)(xing)、減震(zhen)性(xing)(xing)(xing)(xing)、耐(nai)(nai)磨性(xing)(xing)(xing)(xing)，因此能很(hen)好(hao)(hao)的補償兩(liang)傳(chuan)動軸(zhou)(zhou)(zhou)(zhou)系(xi)之(zhi)間的各種位(wei)移(yi).星形彈(dan)(dan)性(xing)(xing)(xing)(xing)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)的聚氨脂(zhi)彈(dan)(dan)性(xing)(xing)(xing)(xing)體由凸(tu)形爪塊限(xian)制。特點：預應力下無齒隙的連接(jie)，用(yong)(yong)于(yu)主軸(zhou)(zhou)(zhou)(zhou)傳(chuan)動、升降平(ping)臺和(he)機床等(deng)。
