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湊，傳遞(di)扭矩(ju)大，使用壽命(ming)長，免維護，耐(nai)(nai)高溫，耐(nai)(nai)酸堿防腐(fu)蝕，適用于(yu)高溫高速及有腐(fu)蝕工況環(huan)境的(de)軸系(xi)傳動。

膜(mo)片(pian)型聯軸(zhou)器(qi)(qi)(qi)能補償(chang)主動(dong)機(ji)與從動(dong)機(ji)之間由于制造誤差、安裝誤差、承載(zai)變形以及溫升變化的(de)影響等(deng)所(suo)引起(qi)的(de)軸(zhou)向、徑向和(he)角向偏(pian)移(yi)。膜(mo)片(pian)彈(dan)性(xing)聯軸(zhou)器(qi)(qi)(qi)屬金屬彈(dan)性(xing)元件撓性(xing)聯軸(zhou)器(qi)(qi)(qi)，其依(yi)靠金屬聯軸(zhou)器(qi)(qi)(qi)膜(mo)片(pian)來聯接主、從動(dong)機(ji)傳(chuan)遞(di)扭矩，具有彈(dan)性(xing)減(jian)振(zhen)、無噪聲、不需潤滑的(de)優(you)點。
