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(di)扭矩(ju)大，使用壽命(ming)長，免(mian)維護，耐高溫，耐酸堿防腐蝕，適(shi)用于高溫高速及有腐蝕工況環境的(de)軸(zhou)系傳動。

膜片(pian)型聯(lian)(lian)軸器能補償(chang)主動(dong)機(ji)與(yu)從(cong)(cong)動(dong)機(ji)之間(jian)由(you)于(yu)制造誤差、安裝誤差、承載變形(xing)以及(ji)溫(wen)升變化的影響等所引起(qi)的軸向、徑向和角向偏移(yi)。膜片(pian)彈性(xing)聯(lian)(lian)軸器屬金屬彈性(xing)元(yuan)件(jian)撓性(xing)聯(lian)(lian)軸器，其(qi)依靠(kao)金屬聯(lian)(lian)軸器膜片(pian)來聯(lian)(lian)接主、從(cong)(cong)動(dong)機(ji)傳遞扭(niu)矩，具有彈性(xing)減振、無噪(zao)聲、不(bu)需潤(run)滑的優點。

膜(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器至少(shao)由(you)一(yi)(yi)個膜(mo)片(pian)(pian)(pian)和兩個軸(zhou)(zhou)(zhou)套組成。膜(mo)片(pian)(pian)(pian)被(bei)用銷釘緊(jin)固(gu)在(zai)(zai)軸(zhou)(zhou)(zhou)套上一(yi)(yi)般不(bu)(bu)會(hui)松動或引起(qi)膜(mo)片(pian)(pian)(pian)和軸(zhou)(zhou)(zhou)套之(zhi)間(jian)的(de)反沖。有一(yi)(yi)些生產商提供(gong)兩個膜(mo)片(pian)(pian)(pian)的(de)，也(ye)有提供(gong)三個膜(mo)片(pian)(pian)(pian)的(de)，中間(jian)有一(yi)(yi)個或兩個剛(gang)性元件，兩邊(bian) 再連在(zai)(zai)軸(zhou)(zhou)(zhou)套上。單膜(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器和雙膜(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器的(de)不(bu)(bu)同(tong)(tong)(tong)之(zhi)處(chu)是(shi)處(chu)理各種偏差能力的(de)不(bu)(bu)同(tong)(tong)(tong)，鑒于(yu)其需要膜(mo)片(pian)(pian)(pian)能復雜的(de)彎曲，所以單膜(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器不(bu)(bu)太(tai)適(shi)應偏心。而雙膜(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器可以同(tong)(tong)(tong)時曲向(xiang)不(bu)(bu)同(tong)(tong)(tong)的(de)方向(xiang)，以此來(lai)補償偏心。
