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(jin)湊，傳遞扭矩大，使用壽命長，免(mian)維護，耐高(gao)溫，耐酸堿防腐蝕，適用于高(gao)溫高(gao)速及有腐蝕工況(kuang)環境的軸(zhou)系傳動。

膜(mo)片型聯(lian)軸器能補(bu)償(chang)主動(dong)機(ji)與從動(dong)機(ji)之間由(you)于制造誤差、安裝(zhuang)誤差、承載變形以及溫升變化的影響等所引起(qi)的軸向(xiang)、徑向(xiang)和角向(xiang)偏移(yi)。膜(mo)片彈(dan)性聯(lian)軸器屬金(jin)屬彈(dan)性元件撓性聯(lian)軸器，其依靠(kao)金(jin)屬聯(lian)軸器膜(mo)片來聯(lian)接主、從動(dong)機(ji)傳遞扭矩，具有彈(dan)性減振(zhen)、無噪聲、不需潤滑的優點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器(qi)(qi)至少由一個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)和兩(liang)個(ge)軸套組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)被用(yong)銷釘緊固在軸套上一般(ban)不(bu)會(hui)松動或引起膜(mo)(mo)片(pian)(pian)(pian)(pian)和軸套之間的(de)反沖。有一些生產(chan)商提供(gong)兩(liang)個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，也有提供(gong)三個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，中間有一個(ge)或兩(liang)個(ge)剛(gang)性元件，兩(liang)邊(bian) 再連在軸套上。單膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器(qi)(qi)和雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器(qi)(qi)的(de)不(bu)同(tong)(tong)之處是(shi)處理各種偏(pian)差能力的(de)不(bu)同(tong)(tong)，鑒于其需(xu)要膜(mo)(mo)片(pian)(pian)(pian)(pian)能復雜(za)的(de)彎曲(qu)，所(suo)以單膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器(qi)(qi)不(bu)太適應偏(pian)心。而(er)雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器(qi)(qi)可以同(tong)(tong)時曲(qu)向不(bu)同(tong)(tong)的(de)方向，以此來補(bu)償偏(pian)心。
