星(xing)(xing)形(xing)聯(lian)(lian)軸器(qi)高速運(yun)轉時(shi)由于受離心(xin)力(li)(li)的作用而產生的徑向運(yun)動將(jiang)加(jia)速其磨(mo)損(sun)，加(jia)設外殼(ke)。除了能(neng)(neng)防塵(chen)(chen)存油(you)外，減薄量不足(zu)可能(neng)(neng)會(hui)造成干涉(she)，減薄量過大會(hui)削弱齒(chi)(chi)(chi)(chi)(chi)的強度(du)，且會(hui)側隙(xi)很大。外齒(chi)(chi)(chi)(chi)(chi)的接(jie)觸(chu)條(tiao)件得到改善，避免了在(zai)角位移(yi)條(tiao)件下直(zhi)齒(chi)(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)(chi)端(duan)棱邊擠(ji)壓(ya)，應(ying)力(li)(li)集中的弊端(duan)，同時(shi)改善了齒(chi)(chi)(chi)(chi)(chi)面(mian)(mian)摩擦、磨(mo)損(sun)狀況(kuang)，降低(di)了噪聲(sheng)，維(wei)修(xiu)周期長。星(xing)(xing)形(xing)彈性聯(lian)(lian)軸器(qi)外齒(chi)(chi)(chi)(chi)(chi)套齒(chi)(chi)(chi)(chi)(chi)端(duan)呈喇叭形(xing)狀，故不宜在(zai)高速和有沖(chong)擊載荷情(qing)況(kuang)下使(shi)(shi)用，也不宜用于立軸的聯(lian)(lian)接(jie)。星(xing)(xing)型(xing)彈性聯(lian)(lian)軸器(qi)整體結構設計時(shi)，要充分注意齒(chi)(chi)(chi)(chi)(chi)面(mian)(mian)與滾(gun)子之間的潤(run)滑及(ji)防塵(chen)(chen)，還有安(an)全防護(hu)作用。因為鏈(lian)條(tiao)萬(wan)一破斷，可能(neng)(neng)造成人(ren)身事故。鼓(gu)度(du)曲(qu)線(xian)曲(qu)率半徑與內(nei)齒(chi)(chi)(chi)(chi)(chi)單(dan)側減薄量成正比，即它與齒(chi)(chi)(chi)(chi)(chi)的嚙合間隙(xi)有關，使(shi)(shi)內(nei)、外齒(chi)(chi)(chi)(chi)(chi)裝拆十分方便。
