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(chuan)遞(di)扭矩大(da)，使用壽命長，免維(wei)護，耐(nai)高(gao)溫(wen)，耐(nai)酸(suan)堿(jian)防腐(fu)蝕(shi)(shi)，適用于(yu)高(gao)溫(wen)高(gao)速及有腐(fu)蝕(shi)(shi)工(gong)況環境的軸系(xi)傳(chuan)動。

膜(mo)片(pian)型聯軸(zhou)(zhou)器(qi)(qi)能補償主(zhu)動(dong)(dong)機與從動(dong)(dong)機之間由于(yu)制造誤差、安(an)裝誤差、承載變形(xing)以及溫升變化的影響等(deng)所引(yin)起的軸(zhou)(zhou)向、徑向和角向偏移。膜(mo)片(pian)彈(dan)(dan)性聯軸(zhou)(zhou)器(qi)(qi)屬金屬彈(dan)(dan)性元(yuan)件撓性聯軸(zhou)(zhou)器(qi)(qi)，其依靠(kao)金屬聯軸(zhou)(zhou)器(qi)(qi)膜(mo)片(pian)來聯接主(zhu)、從動(dong)(dong)機傳遞扭矩，具有彈(dan)(dan)性減振、無噪聲、不需潤滑的優(you)點。
