星(xing)形聯(lian)軸器(qi)高速運轉時由(you)于受離心力(li)(li)的(de)(de)(de)(de)作用(yong)(yong)而產生(sheng)的(de)(de)(de)(de)徑向運動將加速其(qi)磨損，加設(she)外(wai)殼。除了(le)(le)能(neng)防(fang)塵存油外(wai)，減薄(bo)量不(bu)足可能(neng)會(hui)(hui)造成干涉，減薄(bo)量過大會(hui)(hui)削弱齒(chi)(chi)的(de)(de)(de)(de)強度，且會(hui)(hui)側隙很大。外(wai)齒(chi)(chi)的(de)(de)(de)(de)接(jie)(jie)觸(chu)條件得到(dao)改善，避免了(le)(le)在角位移條件下直(zhi)齒(chi)(chi)齒(chi)(chi)端棱邊擠壓，應力(li)(li)集中的(de)(de)(de)(de)弊端，同時改善了(le)(le)齒(chi)(chi)面摩擦、磨損狀況，降低了(le)(le)噪聲，維修周期長。星(xing)形彈性聯(lian)軸器(qi)外(wai)齒(chi)(chi)套齒(chi)(chi)端呈喇叭形狀，故(gu)不(bu)宜(yi)(yi)在高速和有(you)沖擊載荷情況下使(shi)用(yong)(yong)，也不(bu)宜(yi)(yi)用(yong)(yong)于立軸的(de)(de)(de)(de)聯(lian)接(jie)(jie)。星(xing)型(xing)彈性聯(lian)軸器(qi)整體結構設(she)計時，要(yao)充分(fen)注意齒(chi)(chi)面與(yu)滾子之間的(de)(de)(de)(de)潤滑及防(fang)塵，還有(you)安(an)全防(fang)護作用(yong)(yong)。因為鏈條萬一破斷，可能(neng)造成人身事故(gu)。鼓度曲線(xian)曲率半(ban)徑與(yu)內(nei)(nei)齒(chi)(chi)單側減薄(bo)量成正(zheng)比，即(ji)它(ta)與(yu)齒(chi)(chi)的(de)(de)(de)(de)嚙(nie)合(he)間隙有(you)關，使(shi)內(nei)(nei)、外(wai)齒(chi)(chi)裝拆(chai)十分(fen)方便。

星(xing)(xing)型聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)有時被(bei)誤(wu)認為(wei)是梅花聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)，他們(men)安裝后的(de)(de)外形(xing)(xing)幾乎(hu)相似，但(dan)是同(tong)等(deng)型號(hao)下(xia)，星(xing)(xing)形(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)承受的(de)(de)扭(niu)力更大，相對梅花聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)，它的(de)(de)內孔(kong)和外形(xing)(xing)可(ke)以(yi)做到更小(xiao)。星(xing)(xing)形(xing)(xing)彈(dan)性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)聚氨(an)脂彈(dan)性(xing)(xing)體由凸形(xing)(xing)爪塊限(xian)制，聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)是以(yi)工(gong)(gong)程塑(su)料(liao)作(zuo)彈(dan)性(xing)(xing)元(yuan)件(jian)，適用于(yu)聯(lian)(lian)(lian)接兩(liang)同(tong)軸(zhou)(zhou)(zhou)(zhou)線的(de)(de)傳動(dong)軸(zhou)(zhou)(zhou)(zhou)系，具有補償(chang)兩(liang)軸(zhou)(zhou)(zhou)(zhou)相對偏移、緩沖(chong)、減(jian)震、耐(nai)(nai)磨性(xing)(xing)能(neng)(neng)，適應(ying)場(chang)合普(pu)遍 ，傳遞轉矩(ju)20-35000.N.M,工(gong)(gong)作(zuo)溫(wen)度-35-+80攝氏(shi)度。星(xing)(xing)型彈(dan)性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)中的(de)(de)彈(dan)性(xing)(xing)元(yuan)件(jian)是工(gong)(gong)程塑(su)料(liao)，由于(yu)該(gai)工(gong)(gong)程塑(su)料(liao)具有良好的(de)(de)彈(dan)性(xing)(xing)、緩沖(chong)性(xing)(xing)、減(jian)震性(xing)(xing)、耐(nai)(nai)磨性(xing)(xing)，因此能(neng)(neng)很好的(de)(de)補償(chang)兩(liang)傳動(dong)軸(zhou)(zhou)(zhou)(zhou)系之間的(de)(de)各(ge)種位移.星(xing)(xing)形(xing)(xing)彈(dan)性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)的(de)(de)聚氨(an)脂彈(dan)性(xing)(xing)體由凸形(xing)(xing)爪塊限(xian)制。特點：預應(ying)力下(xia)無(wu)齒(chi)隙(xi)的(de)(de)連接，用于(yu)主軸(zhou)(zhou)(zhou)(zhou)傳動(dong)、升降平臺(tai)和機床等(deng)。
