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(jie)構緊湊(cou)，傳遞扭矩(ju)大(da)，使用壽命長，免維護，耐高溫，耐酸堿防腐蝕，適用于高溫高速(su)及有腐蝕工況環(huan)境的軸系傳動(dong)。

膜(mo)片型(xing)聯(lian)(lian)軸器能補償主動(dong)機與(yu)從動(dong)機之間由于制造誤(wu)差(cha)、安裝(zhuang)誤(wu)差(cha)、承載變形以(yi)及溫升變化的影響等所引(yin)起(qi)的軸向(xiang)(xiang)(xiang)、徑向(xiang)(xiang)(xiang)和角(jiao)向(xiang)(xiang)(xiang)偏移。膜(mo)片彈(dan)(dan)性聯(lian)(lian)軸器屬金屬彈(dan)(dan)性元件撓性聯(lian)(lian)軸器，其依靠(kao)金屬聯(lian)(lian)軸器膜(mo)片來聯(lian)(lian)接主、從動(dong)機傳遞扭矩，具有彈(dan)(dan)性減振(zhen)、無(wu)噪聲(sheng)、不需潤滑的優(you)點。
