星形聯軸器(qi)高速運轉時由于受離(li)心力的(de)(de)作(zuo)用而產生(sheng)的(de)(de)徑向運動將加速其磨(mo)損(sun)，加設(she)外(wai)(wai)殼(ke)。除了能防(fang)塵存油(you)外(wai)(wai)，減(jian)薄(bo)量不(bu)(bu)足可能會造成(cheng)干(gan)涉(she)，減(jian)薄(bo)量過大(da)會削弱(ruo)齒(chi)(chi)(chi)的(de)(de)強度，且會側隙很大(da)。外(wai)(wai)齒(chi)(chi)(chi)的(de)(de)接(jie)觸條(tiao)件(jian)得到改善(shan)，避免了在(zai)角位(wei)移條(tiao)件(jian)下直(zhi)齒(chi)(chi)(chi)齒(chi)(chi)(chi)端棱邊擠壓，應力集中(zhong)的(de)(de)弊端，同時改善(shan)了齒(chi)(chi)(chi)面(mian)摩擦(ca)、磨(mo)損(sun)狀(zhuang)況，降低了噪(zao)聲，維修周期長。星形彈性聯軸器(qi)外(wai)(wai)齒(chi)(chi)(chi)套齒(chi)(chi)(chi)端呈喇(la)叭(ba)形狀(zhuang)，故不(bu)(bu)宜在(zai)高速和有沖擊載荷(he)情況下使用，也(ye)不(bu)(bu)宜用于立軸的(de)(de)聯接(jie)。星型彈性聯軸器(qi)整體結構設(she)計時，要(yao)充(chong)分注(zhu)意(yi)齒(chi)(chi)(chi)面(mian)與滾子(zi)之(zhi)間(jian)(jian)的(de)(de)潤滑及防(fang)塵，還有安全防(fang)護作(zuo)用。因為鏈條(tiao)萬一(yi)破(po)斷，可能造成(cheng)人身事(shi)故。鼓度曲線曲率(lv)半徑與內(nei)齒(chi)(chi)(chi)單側減(jian)薄(bo)量成(cheng)正比，即它(ta)與齒(chi)(chi)(chi)的(de)(de)嚙合間(jian)(jian)隙有關，使內(nei)、外(wai)(wai)齒(chi)(chi)(chi)裝拆十分方(fang)便。

星(xing)型聯(lian)(lian)軸(zhou)器(qi)(qi)有時(shi)被誤認為是(shi)梅花(hua)聯(lian)(lian)軸(zhou)器(qi)(qi)，他們安裝后的(de)(de)外(wai)形(xing)(xing)幾(ji)乎相(xiang)似，但是(shi)同等型號下，星(xing)形(xing)(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)承受的(de)(de)扭力更(geng)(geng)大，相(xiang)對(dui)梅花(hua)聯(lian)(lian)軸(zhou)器(qi)(qi)，它的(de)(de)內孔和外(wai)形(xing)(xing)可以(yi)做到更(geng)(geng)小(xiao)。星(xing)形(xing)(xing)彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)聚氨(an)脂(zhi)彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)體(ti)(ti)由(you)凸形(xing)(xing)爪塊限(xian)制，聯(lian)(lian)軸(zhou)器(qi)(qi)是(shi)以(yi)工程(cheng)(cheng)塑(su)料作(zuo)彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)元(yuan)件，適(shi)用于聯(lian)(lian)接兩(liang)(liang)同軸(zhou)線的(de)(de)傳動(dong)軸(zhou)系(xi)，具(ju)有補償(chang)兩(liang)(liang)軸(zhou)相(xiang)對(dui)偏(pian)移、緩(huan)沖(chong)、減(jian)震、耐磨性(xing)(xing)(xing)(xing)(xing)能(neng)，適(shi)應(ying)場(chang)合普(pu)遍(bian) ，傳遞轉矩20-35000.N.M,工作(zuo)溫(wen)度(du)-35-+80攝氏(shi)度(du)。星(xing)型彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)中的(de)(de)彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)元(yuan)件是(shi)工程(cheng)(cheng)塑(su)料，由(you)于該工程(cheng)(cheng)塑(su)料具(ju)有良好的(de)(de)彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)、緩(huan)沖(chong)性(xing)(xing)(xing)(xing)(xing)、減(jian)震性(xing)(xing)(xing)(xing)(xing)、耐磨性(xing)(xing)(xing)(xing)(xing)，因此(ci)能(neng)很好的(de)(de)補償(chang)兩(liang)(liang)傳動(dong)軸(zhou)系(xi)之間的(de)(de)各(ge)種位移.星(xing)形(xing)(xing)彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)的(de)(de)聚氨(an)脂(zhi)彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)(xing)(xing)體(ti)(ti)由(you)凸形(xing)(xing)爪塊限(xian)制。特(te)點：預應(ying)力下無齒隙的(de)(de)連接，用于主軸(zhou)傳動(dong)、升降平臺和機床等。
