星(xing)形聯(lian)(lian)(lian)軸(zhou)器(qi)高速(su)(su)運轉(zhuan)時(shi)由(you)于(yu)受離(li)心(xin)力的作用(yong)而產生的徑(jing)(jing)向運動將加速(su)(su)其磨損，加設外殼。除了能(neng)防塵存油外，減(jian)薄(bo)量(liang)不足可(ke)能(neng)會造成干涉，減(jian)薄(bo)量(liang)過大(da)會削弱齒(chi)(chi)的強度(du)，且(qie)會側隙(xi)很大(da)。外齒(chi)(chi)的接(jie)觸條(tiao)件得到改善(shan)，避免(mian)了在(zai)角位移條(tiao)件下直(zhi)齒(chi)(chi)齒(chi)(chi)端(duan)棱邊擠壓，應力集中的弊端(duan)，同時(shi)改善(shan)了齒(chi)(chi)面摩擦(ca)、磨損狀況，降低了噪聲，維修周期長。星(xing)形彈(dan)性聯(lian)(lian)(lian)軸(zhou)器(qi)外齒(chi)(chi)套齒(chi)(chi)端(duan)呈喇叭(ba)形狀，故(gu)不宜在(zai)高速(su)(su)和有(you)沖擊載(zai)荷情況下使用(yong)，也不宜用(yong)于(yu)立軸(zhou)的聯(lian)(lian)(lian)接(jie)。星(xing)型彈(dan)性聯(lian)(lian)(lian)軸(zhou)器(qi)整體結構設計時(shi)，要(yao)充分注意齒(chi)(chi)面與滾子之間(jian)的潤滑及防塵，還(huan)有(you)安全(quan)防護(hu)作用(yong)。因為鏈(lian)條(tiao)萬一破斷(duan)，可(ke)能(neng)造成人(ren)身事故(gu)。鼓度(du)曲線曲率(lv)半徑(jing)(jing)與內齒(chi)(chi)單側減(jian)薄(bo)量(liang)成正比，即它(ta)與齒(chi)(chi)的嚙(nie)合間(jian)隙(xi)有(you)關，使內、外齒(chi)(chi)裝拆十分方便。
