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。膜片式聯軸器結構緊(jin)湊，傳遞扭矩大(da)，使(shi)用壽命長，免(mian)維(wei)護(hu)，耐高溫，耐酸(suan)堿防腐蝕，適用于高溫高速(su)及(ji)有腐蝕工況(kuang)環境的軸(zhou)系傳動。

膜片型聯(lian)軸器(qi)(qi)能補償(chang)主動(dong)機(ji)與從(cong)動(dong)機(ji)之間由于(yu)制造(zao)誤差(cha)、安裝誤差(cha)、承載變(bian)(bian)形以及溫升(sheng)變(bian)(bian)化的影響(xiang)等所(suo)引(yin)起的軸向(xiang)、徑向(xiang)和角向(xiang)偏移。膜片彈(dan)性聯(lian)軸器(qi)(qi)屬金(jin)屬彈(dan)性元(yuan)件(jian)撓(nao)性聯(lian)軸器(qi)(qi)，其依(yi)靠(kao)金(jin)屬聯(lian)軸器(qi)(qi)膜片來(lai)聯(lian)接主、從(cong)動(dong)機(ji)傳遞(di)扭(niu)矩，具有(you)彈(dan)性減振、無噪(zao)聲、不需潤滑的優點。

膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)至少由一個膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和兩個軸(zhou)(zhou)套組(zu)成。膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)被用銷釘緊固在軸(zhou)(zhou)套上一般不(bu)會松(song)動或(huo)引(yin)起(qi)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和軸(zhou)(zhou)套之(zhi)間的(de)反沖(chong)。有(you)一些生產商提(ti)供兩個膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的(de)，也(ye)有(you)提(ti)供三個膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的(de)，中(zhong)間有(you)一個或(huo)兩個剛性(xing)元件，兩邊 再(zai)連(lian)在軸(zhou)(zhou)套上。單(dan)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)和雙膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)的(de)不(bu)同(tong)之(zhi)處是處理各種(zhong)偏(pian)差能力的(de)不(bu)同(tong)，鑒于(yu)其需要膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)能復雜的(de)彎曲(qu)，所以(yi)(yi)(yi)單(dan)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)不(bu)太適應偏(pian)心。而雙膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)可以(yi)(yi)(yi)同(tong)時曲(qu)向不(bu)同(tong)的(de)方向，以(yi)(yi)(yi)此來補(bu)償偏(pian)心。
