星(xing)形聯(lian)軸(zhou)器高(gao)速(su)運轉時由于受離心力的(de)(de)作(zuo)用(yong)而(er)產生的(de)(de)徑(jing)向運動將加(jia)速(su)其磨(mo)(mo)損，加(jia)設(she)外(wai)殼。除了能防(fang)塵存油(you)外(wai)，減(jian)薄量(liang)不足(zu)可(ke)能會造成(cheng)干涉，減(jian)薄量(liang)過大會削弱齒(chi)(chi)(chi)的(de)(de)強度，且(qie)會側隙很大。外(wai)齒(chi)(chi)(chi)的(de)(de)接觸條件(jian)得到改(gai)善(shan)，避免了在角位移條件(jian)下(xia)直齒(chi)(chi)(chi)齒(chi)(chi)(chi)端棱邊擠壓，應力集中的(de)(de)弊端，同(tong)時改(gai)善(shan)了齒(chi)(chi)(chi)面摩擦、磨(mo)(mo)損狀(zhuang)況(kuang)，降(jiang)低(di)了噪(zao)聲，維(wei)修周期(qi)長。星(xing)形彈(dan)性聯(lian)軸(zhou)器外(wai)齒(chi)(chi)(chi)套齒(chi)(chi)(chi)端呈喇叭形狀(zhuang)，故不宜在高(gao)速(su)和有沖擊載荷情況(kuang)下(xia)使(shi)用(yong)，也不宜用(yong)于立(li)軸(zhou)的(de)(de)聯(lian)接。星(xing)型彈(dan)性聯(lian)軸(zhou)器整體(ti)結構設(she)計時，要充分(fen)注(zhu)意齒(chi)(chi)(chi)面與(yu)(yu)(yu)滾子之(zhi)間的(de)(de)潤滑及防(fang)塵，還有安全(quan)防(fang)護作(zuo)用(yong)。因為鏈條萬一破斷，可(ke)能造成(cheng)人身事故。鼓度曲線曲率半徑(jing)與(yu)(yu)(yu)內(nei)齒(chi)(chi)(chi)單側減(jian)薄量(liang)成(cheng)正比(bi)，即它與(yu)(yu)(yu)齒(chi)(chi)(chi)的(de)(de)嚙合間隙有關(guan)，使(shi)內(nei)、外(wai)齒(chi)(chi)(chi)裝拆十分(fen)方(fang)便。
