膜片聯軸器在傳遞扭矩的同時通過彈性膜片的的變形來補償軸向和角向的位移，是一種高性能的金屬彈性撓性聯軸器。膜片式聯軸器結構(gou)緊湊，傳遞扭(niu)矩大，使用(yong)(yong)壽命長，免維護，耐(nai)高(gao)溫，耐(nai)酸堿防腐蝕，適用(yong)(yong)于高(gao)溫高(gao)速及有腐蝕工(gong)況環境的(de)軸系傳動。

膜(mo)片(pian)(pian)型(xing)聯軸器(qi)能補(bu)償(chang)主(zhu)(zhu)動機(ji)與從(cong)動機(ji)之間由于(yu)制(zhi)造(zao)誤差、安裝誤差、承載變形以及溫升變化的影響(xiang)等所引(yin)起的軸向、徑向和角(jiao)向偏移。膜(mo)片(pian)(pian)彈(dan)性聯軸器(qi)屬(shu)金(jin)(jin)屬(shu)彈(dan)性元件撓性聯軸器(qi)，其(qi)依靠金(jin)(jin)屬(shu)聯軸器(qi)膜(mo)片(pian)(pian)來聯接主(zhu)(zhu)、從(cong)動機(ji)傳遞扭(niu)矩，具(ju)有彈(dan)性減振、無(wu)噪(zao)聲、不需潤滑(hua)的優點(dian)。

膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)(qi)至少(shao)由一個膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和(he)兩(liang)個軸(zhou)套組成(cheng)。膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)被用(yong)銷釘(ding)緊固在(zai)軸(zhou)套上一般不(bu)會(hui)松動或引起膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和(he)軸(zhou)套之間的(de)反沖。有一些生產商提供(gong)(gong)兩(liang)個膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的(de)，也(ye)有提供(gong)(gong)三個膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的(de)，中(zhong)間有一個或兩(liang)個剛性元件，兩(liang)邊 再連在(zai)軸(zhou)套上。單膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)(qi)和(he)雙膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)(qi)的(de)不(bu)同之處(chu)是處(chu)理(li)各種偏(pian)差能力的(de)不(bu)同，鑒于(yu)其需要膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)能復雜的(de)彎曲(qu)，所以單膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)(qi)不(bu)太適應偏(pian)心。而(er)雙膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)(qi)可(ke)以同時曲(qu)向(xiang)不(bu)同的(de)方(fang)向(xiang)，以此來補償偏(pian)心。
