星形聯(lian)(lian)(lian)軸器(qi)高速(su)運轉時由于受離心力(li)的(de)作(zuo)用(yong)而產生(sheng)的(de)徑向運動(dong)將加速(su)其磨損(sun)，加設外(wai)殼(ke)。除(chu)了(le)能防(fang)(fang)(fang)塵存油外(wai)，減薄(bo)(bo)(bo)量(liang)(liang)不(bu)足可能會造成(cheng)干涉，減薄(bo)(bo)(bo)量(liang)(liang)過大會削(xue)弱齒(chi)(chi)的(de)強度(du)，且會側隙很大。外(wai)齒(chi)(chi)的(de)接(jie)(jie)觸條(tiao)(tiao)件(jian)得到改善(shan)，避免了(le)在角位移(yi)條(tiao)(tiao)件(jian)下直齒(chi)(chi)齒(chi)(chi)端(duan)棱邊擠壓，應力(li)集中(zhong)的(de)弊(bi)端(duan)，同(tong)時改善(shan)了(le)齒(chi)(chi)面摩(mo)擦、磨損(sun)狀況，降(jiang)低了(le)噪聲(sheng)，維修周期長(chang)。星形彈性聯(lian)(lian)(lian)軸器(qi)外(wai)齒(chi)(chi)套齒(chi)(chi)端(duan)呈喇叭形狀，故不(bu)宜在高速(su)和有沖擊載(zai)荷情況下使用(yong)，也不(bu)宜用(yong)于立軸的(de)聯(lian)(lian)(lian)接(jie)(jie)。星型彈性聯(lian)(lian)(lian)軸器(qi)整體結構設計時，要充分(fen)注意齒(chi)(chi)面與(yu)滾(gun)子之(zhi)間的(de)潤(run)滑(hua)及防(fang)(fang)(fang)塵，還有安(an)全防(fang)(fang)(fang)護作(zuo)用(yong)。因為鏈條(tiao)(tiao)萬一破斷，可能造成(cheng)人身事(shi)故。鼓度(du)曲線曲率半(ban)徑與(yu)內(nei)齒(chi)(chi)單(dan)側減薄(bo)(bo)(bo)量(liang)(liang)成(cheng)正比(bi)，即它與(yu)齒(chi)(chi)的(de)嚙(nie)合(he)間隙有關，使內(nei)、外(wai)齒(chi)(chi)裝(zhuang)拆(chai)十分(fen)方便。
