星形聯(lian)軸器高(gao)速(su)(su)運(yun)轉時(shi)由于受離心(xin)力的作用(yong)而產生的徑向運(yun)動將加(jia)速(su)(su)其(qi)磨損(sun)，加(jia)設(she)外殼。除了(le)能(neng)防(fang)塵(chen)存油外，減(jian)(jian)薄(bo)量(liang)不足可能(neng)會造(zao)成干涉，減(jian)(jian)薄(bo)量(liang)過大會削弱齒(chi)(chi)(chi)的強度(du)(du)，且會側(ce)隙很大。外齒(chi)(chi)(chi)的接(jie)(jie)觸條(tiao)件得(de)到(dao)改(gai)善(shan)，避免了(le)在(zai)角位(wei)移條(tiao)件下(xia)直齒(chi)(chi)(chi)齒(chi)(chi)(chi)端(duan)棱邊擠壓，應力集(ji)中(zhong)的弊(bi)端(duan)，同時(shi)改(gai)善(shan)了(le)齒(chi)(chi)(chi)面摩(mo)擦、磨損(sun)狀(zhuang)況，降低了(le)噪聲，維修周期長。星形彈(dan)性(xing)聯(lian)軸器外齒(chi)(chi)(chi)套齒(chi)(chi)(chi)端(duan)呈(cheng)喇叭形狀(zhuang)，故不宜(yi)(yi)在(zai)高(gao)速(su)(su)和有沖(chong)擊載荷(he)情況下(xia)使(shi)用(yong)，也不宜(yi)(yi)用(yong)于立軸的聯(lian)接(jie)(jie)。星型彈(dan)性(xing)聯(lian)軸器整體結構設(she)計時(shi)，要充分注(zhu)意齒(chi)(chi)(chi)面與滾(gun)子之(zhi)間(jian)的潤滑及防(fang)塵(chen)，還(huan)有安全防(fang)護作用(yong)。因為(wei)鏈(lian)條(tiao)萬(wan)一破斷，可能(neng)造(zao)成人身事故。鼓度(du)(du)曲(qu)線曲(qu)率(lv)半徑與內齒(chi)(chi)(chi)單側(ce)減(jian)(jian)薄(bo)量(liang)成正比，即它與齒(chi)(chi)(chi)的嚙合間(jian)隙有關，使(shi)內、外齒(chi)(chi)(chi)裝拆十(shi)分方(fang)便。

星型聯(lian)(lian)(lian)軸(zhou)(zhou)器有時被(bei)誤認為是梅花聯(lian)(lian)(lian)軸(zhou)(zhou)器，他(ta)們安裝(zhuang)后的(de)(de)(de)外形(xing)(xing)(xing)(xing)幾乎相(xiang)似(si)，但是同等型號下(xia)，星形(xing)(xing)(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器承受的(de)(de)(de)扭力更大，相(xiang)對梅花聯(lian)(lian)(lian)軸(zhou)(zhou)器，它的(de)(de)(de)內(nei)孔和外形(xing)(xing)(xing)(xing)可(ke)以(yi)做到更小。星形(xing)(xing)(xing)(xing)彈性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器聚氨(an)脂彈性(xing)(xing)體由凸(tu)形(xing)(xing)(xing)(xing)爪塊(kuai)限(xian)制，聯(lian)(lian)(lian)軸(zhou)(zhou)器是以(yi)工(gong)(gong)程塑(su)料作彈性(xing)(xing)元件(jian)，適用(yong)于(yu)聯(lian)(lian)(lian)接兩(liang)同軸(zhou)(zhou)線的(de)(de)(de)傳(chuan)動軸(zhou)(zhou)系(xi)，具有補償兩(liang)軸(zhou)(zhou)相(xiang)對偏移、緩沖(chong)、減(jian)震、耐磨(mo)性(xing)(xing)能，適應(ying)場合普遍 ，傳(chuan)遞轉矩20-35000.N.M,工(gong)(gong)作溫(wen)度(du)-35-+80攝氏度(du)。星型彈性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器中的(de)(de)(de)彈性(xing)(xing)元件(jian)是工(gong)(gong)程塑(su)料，由于(yu)該工(gong)(gong)程塑(su)料具有良好的(de)(de)(de)彈性(xing)(xing)、緩沖(chong)性(xing)(xing)、減(jian)震性(xing)(xing)、耐磨(mo)性(xing)(xing)，因此(ci)能很好的(de)(de)(de)補償兩(liang)傳(chuan)動軸(zhou)(zhou)系(xi)之間的(de)(de)(de)各(ge)種位移.星形(xing)(xing)(xing)(xing)彈性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器的(de)(de)(de)聚氨(an)脂彈性(xing)(xing)體由凸(tu)形(xing)(xing)(xing)(xing)爪塊(kuai)限(xian)制。特點：預應(ying)力下(xia)無齒(chi)隙的(de)(de)(de)連接，用(yong)于(yu)主軸(zhou)(zhou)傳(chuan)動、升降平臺和機(ji)床等。
