星(xing)形聯(lian)軸器(qi)高速(su)運(yun)(yun)轉(zhuan)時(shi)由(you)于受離(li)心力的(de)作用(yong)而產生的(de)徑向運(yun)(yun)動(dong)將加(jia)速(su)其磨(mo)損，加(jia)設外(wai)(wai)(wai)殼。除了(le)能防塵存油(you)外(wai)(wai)(wai)，減(jian)(jian)薄(bo)量(liang)不足可能會造成(cheng)(cheng)干涉，減(jian)(jian)薄(bo)量(liang)過大會削(xue)弱(ruo)齒(chi)(chi)的(de)強度，且(qie)會側隙很大。外(wai)(wai)(wai)齒(chi)(chi)的(de)接(jie)(jie)觸(chu)條(tiao)件(jian)得(de)到(dao)改(gai)善，避免(mian)了(le)在角位移條(tiao)件(jian)下直齒(chi)(chi)齒(chi)(chi)端棱邊擠壓(ya)，應力集(ji)中的(de)弊端，同時(shi)改(gai)善了(le)齒(chi)(chi)面摩擦、磨(mo)損狀況，降(jiang)低(di)了(le)噪聲，維修(xiu)周期長。星(xing)形彈性聯(lian)軸器(qi)外(wai)(wai)(wai)齒(chi)(chi)套齒(chi)(chi)端呈喇叭形狀，故不宜在高速(su)和有沖擊載荷情況下使用(yong)，也(ye)不宜用(yong)于立軸的(de)聯(lian)接(jie)(jie)。星(xing)型彈性聯(lian)軸器(qi)整體結(jie)構設計時(shi)，要充(chong)分注意(yi)齒(chi)(chi)面與滾子之間的(de)潤滑及(ji)防塵，還有安(an)全(quan)防護作用(yong)。因為(wei)鏈條(tiao)萬一破(po)斷，可能造成(cheng)(cheng)人身事故。鼓(gu)度曲線曲率半徑與內齒(chi)(chi)單側減(jian)(jian)薄(bo)量(liang)成(cheng)(cheng)正比(bi)，即它與齒(chi)(chi)的(de)嚙合間隙有關，使內、外(wai)(wai)(wai)齒(chi)(chi)裝(zhuang)拆十分方便(bian)。
