星(xing)形(xing)(xing)聯(lian)軸(zhou)(zhou)(zhou)器高速(su)運轉時(shi)由(you)于(yu)受離(li)心力(li)的(de)作用(yong)(yong)而產生的(de)徑向運動將加速(su)其磨損，加設(she)外(wai)殼(ke)。除了(le)(le)能(neng)防塵(chen)存油外(wai)，減薄(bo)量不足可能(neng)會(hui)造(zao)成干涉，減薄(bo)量過大會(hui)削弱齒(chi)(chi)的(de)強度(du)，且會(hui)側(ce)隙很大。外(wai)齒(chi)(chi)的(de)接(jie)觸條件得(de)到改善(shan)，避免了(le)(le)在角位移條件下直(zhi)齒(chi)(chi)齒(chi)(chi)端棱邊(bian)擠壓(ya)，應力(li)集中的(de)弊端，同時(shi)改善(shan)了(le)(le)齒(chi)(chi)面摩擦、磨損狀(zhuang)況(kuang)(kuang)，降低了(le)(le)噪聲，維修周期長。星(xing)形(xing)(xing)彈(dan)性聯(lian)軸(zhou)(zhou)(zhou)器外(wai)齒(chi)(chi)套(tao)齒(chi)(chi)端呈喇叭形(xing)(xing)狀(zhuang)，故不宜在高速(su)和有(you)沖(chong)擊載荷(he)情況(kuang)(kuang)下使(shi)用(yong)(yong)，也不宜用(yong)(yong)于(yu)立軸(zhou)(zhou)(zhou)的(de)聯(lian)接(jie)。星(xing)型彈(dan)性聯(lian)軸(zhou)(zhou)(zhou)器整體結構(gou)設(she)計(ji)時(shi)，要充分(fen)注(zhu)意齒(chi)(chi)面與滾子之間的(de)潤(run)滑及防塵(chen)，還有(you)安全防護作用(yong)(yong)。因(yin)為鏈條萬一破斷(duan)，可能(neng)造(zao)成人身事(shi)故。鼓(gu)度(du)曲(qu)線曲(qu)率半(ban)徑與內齒(chi)(chi)單(dan)側(ce)減薄(bo)量成正比，即它(ta)與齒(chi)(chi)的(de)嚙合間隙有(you)關(guan)，使(shi)內、外(wai)齒(chi)(chi)裝(zhuang)拆十分(fen)方便。

星(xing)型(xing)聯(lian)(lian)軸器(qi)(qi)(qi)有時被誤(wu)認為是(shi)梅花(hua)聯(lian)(lian)軸器(qi)(qi)(qi)，他們安裝(zhuang)后的(de)(de)外形(xing)(xing)(xing)(xing)幾乎相似，但是(shi)同(tong)(tong)等型(xing)號下(xia)(xia)，星(xing)形(xing)(xing)(xing)(xing)聯(lian)(lian)軸器(qi)(qi)(qi)承受的(de)(de)扭力更(geng)大，相對(dui)梅花(hua)聯(lian)(lian)軸器(qi)(qi)(qi)，它的(de)(de)內(nei)孔和外形(xing)(xing)(xing)(xing)可以做(zuo)到更(geng)小。星(xing)形(xing)(xing)(xing)(xing)彈(dan)(dan)性(xing)(xing)聯(lian)(lian)軸器(qi)(qi)(qi)聚氨脂彈(dan)(dan)性(xing)(xing)體由凸形(xing)(xing)(xing)(xing)爪塊(kuai)限制，聯(lian)(lian)軸器(qi)(qi)(qi)是(shi)以工(gong)(gong)程(cheng)(cheng)塑(su)料作彈(dan)(dan)性(xing)(xing)元件，適用(yong)于(yu)(yu)聯(lian)(lian)接(jie)兩同(tong)(tong)軸線的(de)(de)傳(chuan)動(dong)軸系，具有補(bu)償兩軸相對(dui)偏移(yi)(yi)、緩沖、減震、耐磨性(xing)(xing)能(neng)，適應場合普遍 ，傳(chuan)遞轉矩20-35000.N.M,工(gong)(gong)作溫(wen)度-35-+80攝氏(shi)度。星(xing)型(xing)彈(dan)(dan)性(xing)(xing)聯(lian)(lian)軸器(qi)(qi)(qi)中(zhong)的(de)(de)彈(dan)(dan)性(xing)(xing)元件是(shi)工(gong)(gong)程(cheng)(cheng)塑(su)料，由于(yu)(yu)該(gai)工(gong)(gong)程(cheng)(cheng)塑(su)料具有良好(hao)的(de)(de)彈(dan)(dan)性(xing)(xing)、緩沖性(xing)(xing)、減震性(xing)(xing)、耐磨性(xing)(xing)，因此能(neng)很(hen)好(hao)的(de)(de)補(bu)償兩傳(chuan)動(dong)軸系之間的(de)(de)各種(zhong)位移(yi)(yi).星(xing)形(xing)(xing)(xing)(xing)彈(dan)(dan)性(xing)(xing)聯(lian)(lian)軸器(qi)(qi)(qi)的(de)(de)聚氨脂彈(dan)(dan)性(xing)(xing)體由凸形(xing)(xing)(xing)(xing)爪塊(kuai)限制。特點：預應力下(xia)(xia)無(wu)齒隙的(de)(de)連(lian)接(jie)，用(yong)于(yu)(yu)主軸傳(chuan)動(dong)、升降平臺和機(ji)床等。

彈性柱銷聯軸器是一種結構簡單制造容易，無需潤滑，裝拆彈性柱銷便捷的傳動基礎件，利用兩個帶法蘭孔的半聯和置于起重的非金屬彈性柱銷來傳遞扭矩，適用于中低速和中低扭矩場合。彈性柱銷齒式聯軸器采用非金屬彈性柱銷和兩個帶齒形半聯以及一個外圈的齒形套環設計，利用非金屬彈性的變形來傳遞扭矩同時緩沖減震，補償角向位移。彈性套柱銷聯軸器設計簡單巧妙，適用性較廣的聯軸器，利用帶彈性套的柱銷聯接兩個帶銷孔的半聯，實現扭矩傳遞的同時兼具較大的角向補償，同時減震緩沖性能良好，可以用在速度較快的場合，無需潤滑，銷套更換便捷。
