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)壽命長，免維護，耐高溫，耐酸堿防腐蝕，適用(yong)于高溫高速及有腐蝕工況環境的軸(zhou)系傳動。

膜片型(xing)聯軸(zhou)(zhou)器能(neng)補償(chang)主動機(ji)與從動機(ji)之間由于制造(zao)誤(wu)差、安(an)裝誤(wu)差、承載變形以及溫升變化(hua)的影響等所引(yin)起的軸(zhou)(zhou)向、徑向和角向偏移。膜片彈(dan)(dan)性(xing)聯軸(zhou)(zhou)器屬金(jin)(jin)屬彈(dan)(dan)性(xing)元(yuan)件(jian)撓(nao)性(xing)聯軸(zhou)(zhou)器，其依靠金(jin)(jin)屬聯軸(zhou)(zhou)器膜片來聯接(jie)主、從動機(ji)傳遞扭(niu)矩，具(ju)有(you)彈(dan)(dan)性(xing)減振(zhen)、無噪聲、不需潤(run)滑的優(you)點。

膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)至少(shao)由一(yi)個(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)和(he)(he)兩(liang)個(ge)(ge)軸(zhou)(zhou)套(tao)組成。膜(mo)片(pian)(pian)(pian)(pian)被用(yong)銷釘緊(jin)固在軸(zhou)(zhou)套(tao)上一(yi)般不(bu)(bu)(bu)會(hui)松動(dong)或(huo)引(yin)起膜(mo)片(pian)(pian)(pian)(pian)和(he)(he)軸(zhou)(zhou)套(tao)之間(jian)(jian)的(de)(de)(de)反沖。有一(yi)些生產(chan)商(shang)提供兩(liang)個(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)的(de)(de)(de)，也有提供三(san)個(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)的(de)(de)(de)，中間(jian)(jian)有一(yi)個(ge)(ge)或(huo)兩(liang)個(ge)(ge)剛性(xing)元件，兩(liang)邊 再連(lian)在軸(zhou)(zhou)套(tao)上。單膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)和(he)(he)雙(shuang)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)的(de)(de)(de)不(bu)(bu)(bu)同(tong)之處是處理各種偏差能力的(de)(de)(de)不(bu)(bu)(bu)同(tong)，鑒(jian)于其需要膜(mo)片(pian)(pian)(pian)(pian)能復雜的(de)(de)(de)彎曲，所以單膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)不(bu)(bu)(bu)太適應(ying)偏心。而雙(shuang)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)可以同(tong)時曲向不(bu)(bu)(bu)同(tong)的(de)(de)(de)方向，以此來補(bu)償偏心。
