星(xing)形(xing)聯軸器高速(su)運轉時(shi)由于受離心力的(de)(de)作用(yong)而產生(sheng)的(de)(de)徑(jing)向運動將加(jia)速(su)其磨(mo)損，加(jia)設外(wai)殼。除了能(neng)防(fang)(fang)塵存油外(wai)，減薄(bo)(bo)量(liang)(liang)不(bu)足可(ke)能(neng)會造成(cheng)干涉，減薄(bo)(bo)量(liang)(liang)過(guo)大會削弱齒(chi)(chi)(chi)(chi)的(de)(de)強度(du)，且會側隙很大。外(wai)齒(chi)(chi)(chi)(chi)的(de)(de)接(jie)觸條(tiao)件(jian)得到改善，避免(mian)了在角位移條(tiao)件(jian)下直(zhi)齒(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)端(duan)棱(leng)邊擠壓，應力集中的(de)(de)弊端(duan)，同(tong)時(shi)改善了齒(chi)(chi)(chi)(chi)面摩擦、磨(mo)損狀況，降低(di)了噪聲，維修周期長。星(xing)形(xing)彈(dan)性聯軸器外(wai)齒(chi)(chi)(chi)(chi)套齒(chi)(chi)(chi)(chi)端(duan)呈(cheng)喇叭形(xing)狀，故(gu)(gu)不(bu)宜(yi)在高速(su)和(he)有(you)沖擊載荷情況下使用(yong)，也不(bu)宜(yi)用(yong)于立軸的(de)(de)聯接(jie)。星(xing)型彈(dan)性聯軸器整體結(jie)構設計(ji)時(shi)，要充(chong)分注意(yi)齒(chi)(chi)(chi)(chi)面與(yu)滾子(zi)之間的(de)(de)潤(run)滑及防(fang)(fang)塵，還有(you)安(an)全防(fang)(fang)護作用(yong)。因為鏈條(tiao)萬一破斷(duan)，可(ke)能(neng)造成(cheng)人身事故(gu)(gu)。鼓(gu)度(du)曲線曲率半徑(jing)與(yu)內(nei)齒(chi)(chi)(chi)(chi)單側減薄(bo)(bo)量(liang)(liang)成(cheng)正比，即它與(yu)齒(chi)(chi)(chi)(chi)的(de)(de)嚙合間隙有(you)關，使內(nei)、外(wai)齒(chi)(chi)(chi)(chi)裝拆(chai)十分方便(bian)。

星型聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)有時被誤認為是(shi)(shi)梅花(hua)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)，他們安裝后的(de)(de)外形(xing)(xing)(xing)幾乎(hu)相似(si)，但是(shi)(shi)同等型號(hao)下(xia)，星形(xing)(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)承(cheng)受的(de)(de)扭(niu)力更大，相對(dui)梅花(hua)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)，它(ta)的(de)(de)內孔和外形(xing)(xing)(xing)可以(yi)做到(dao)更小(xiao)。星形(xing)(xing)(xing)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)聚(ju)氨脂彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)體由凸(tu)形(xing)(xing)(xing)爪塊(kuai)限制，聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)是(shi)(shi)以(yi)工程塑(su)料(liao)(liao)作彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)元件(jian)，適用(yong)于聯(lian)(lian)(lian)接(jie)兩同軸(zhou)(zhou)線的(de)(de)傳(chuan)(chuan)動軸(zhou)(zhou)系，具(ju)有補(bu)償兩軸(zhou)(zhou)相對(dui)偏移(yi)、緩(huan)沖、減震(zhen)、耐磨(mo)(mo)性(xing)(xing)(xing)(xing)能(neng)，適應場(chang)合普遍 ，傳(chuan)(chuan)遞轉矩20-35000.N.M,工作溫(wen)度-35-+80攝氏度。星型彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)中的(de)(de)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)元件(jian)是(shi)(shi)工程塑(su)料(liao)(liao)，由于該工程塑(su)料(liao)(liao)具(ju)有良(liang)好的(de)(de)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)、緩(huan)沖性(xing)(xing)(xing)(xing)、減震(zhen)性(xing)(xing)(xing)(xing)、耐磨(mo)(mo)性(xing)(xing)(xing)(xing)，因此(ci)能(neng)很(hen)好的(de)(de)補(bu)償兩傳(chuan)(chuan)動軸(zhou)(zhou)系之間(jian)的(de)(de)各種位(wei)移(yi).星形(xing)(xing)(xing)彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)的(de)(de)聚(ju)氨脂彈(dan)(dan)(dan)性(xing)(xing)(xing)(xing)體由凸(tu)形(xing)(xing)(xing)爪塊(kuai)限制。特點：預應力下(xia)無齒隙的(de)(de)連接(jie)，用(yong)于主軸(zhou)(zhou)傳(chuan)(chuan)動、升降平臺和機床等。
