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，傳遞扭(niu)矩(ju)大，使用(yong)壽命長，免(mian)維(wei)護，耐高溫(wen)，耐酸堿防腐蝕，適(shi)用(yong)于高溫(wen)高速(su)及有腐蝕工(gong)況環(huan)境的軸(zhou)系傳動。

膜片(pian)(pian)型聯(lian)軸(zhou)器(qi)能補(bu)償主動機(ji)與從動機(ji)之間由于制造誤(wu)差、安裝誤(wu)差、承載(zai)變形以及(ji)溫升變化的影響等(deng)所引起的軸(zhou)向(xiang)、徑向(xiang)和角(jiao)向(xiang)偏(pian)移。膜片(pian)(pian)彈性聯(lian)軸(zhou)器(qi)屬(shu)金屬(shu)彈性元件撓性聯(lian)軸(zhou)器(qi)，其依(yi)靠金屬(shu)聯(lian)軸(zhou)器(qi)膜片(pian)(pian)來聯(lian)接主、從動機(ji)傳遞(di)扭矩，具(ju)有彈性減振、無噪聲、不需潤滑的優(you)點(dian)。

膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)(qi)至少由(you)一(yi)個膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和兩(liang)個軸(zhou)(zhou)套組成。膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)被用(yong)銷(xiao)釘(ding)緊(jin)固(gu)在軸(zhou)(zhou)套上(shang)一(yi)般不(bu)(bu)會松動或引起膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和軸(zhou)(zhou)套之間的反沖。有(you)一(yi)些生產商(shang)提供兩(liang)個膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的，也有(you)提供三(san)個膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的，中間有(you)一(yi)個或兩(liang)個剛性元(yuan)件，兩(liang)邊 再(zai)連在軸(zhou)(zhou)套上(shang)。單(dan)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)(qi)和雙(shuang)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)(qi)的不(bu)(bu)同之處是(shi)處理各種偏差能力的不(bu)(bu)同，鑒于其需要膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)能復雜(za)的彎曲，所以單(dan)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)(qi)不(bu)(bu)太(tai)適(shi)應偏心。而雙(shuang)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)(qi)可以同時曲向(xiang)不(bu)(bu)同的方向(xiang)，以此來(lai)補償偏心。
