星形(xing)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)高速運(yun)轉時(shi)由于(yu)受離心力(li)的作(zuo)用而(er)產生的徑(jing)向(xiang)運(yun)動將加速其磨(mo)損，加設(she)外(wai)殼。除了能(neng)防(fang)塵存油外(wai)，減(jian)薄(bo)(bo)量不足(zu)可(ke)能(neng)會造成干涉，減(jian)薄(bo)(bo)量過大會削弱(ruo)齒(chi)(chi)(chi)(chi)的強度(du)，且會側隙很(hen)大。外(wai)齒(chi)(chi)(chi)(chi)的接(jie)觸條(tiao)件得到改善，避免了在(zai)角位移條(tiao)件下(xia)直(zhi)齒(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)端棱邊擠壓，應力(li)集中的弊端，同時(shi)改善了齒(chi)(chi)(chi)(chi)面摩擦、磨(mo)損狀況(kuang)，降低(di)了噪聲，維修周期長。星形(xing)彈(dan)性聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)外(wai)齒(chi)(chi)(chi)(chi)套齒(chi)(chi)(chi)(chi)端呈喇叭形(xing)狀，故不宜在(zai)高速和有沖擊(ji)載荷情況(kuang)下(xia)使用，也不宜用于(yu)立軸(zhou)(zhou)(zhou)的聯(lian)(lian)接(jie)。星型彈(dan)性聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)整體結(jie)構(gou)設(she)計時(shi)，要充分(fen)(fen)注(zhu)意齒(chi)(chi)(chi)(chi)面與滾子之(zhi)間(jian)的潤(run)滑及防(fang)塵，還有安全防(fang)護(hu)作(zuo)用。因為鏈條(tiao)萬(wan)一破斷(duan)，可(ke)能(neng)造成人身(shen)事故。鼓度(du)曲線曲率半徑(jing)與內(nei)齒(chi)(chi)(chi)(chi)單側減(jian)薄(bo)(bo)量成正(zheng)比，即它(ta)與齒(chi)(chi)(chi)(chi)的嚙合間(jian)隙有關，使內(nei)、外(wai)齒(chi)(chi)(chi)(chi)裝拆十(shi)分(fen)(fen)方便。
