RL系列膜片聯軸器是結合歐洲與日本等優質產品基礎之上獨立開發的高品質產品。膜片式聯軸器擁(yong)有更小的(de)體積，更大的(de)同型扭(niu)矩和(he)更合(he)理的(de)配比(bi)尺寸，補償范圍大，質(zhi)量輕轉動慣量小螺栓與膜片(pian)(pian)組的(de)孔連(lian)接部位采用特殊的(de)彈性墊套設(she)計，極大減(jian)小了孔緣部位應力的(de)集中，杜(du)絕膜片(pian)(pian)的(de)撕(si)裂(lie)交(jiao)損，延長使(shi)用壽命。

膜片彈性聯軸器采用模塊化設(she)計，裝(zhuang)配簡單，維修更(geng)換快捷(jie)。性能遠超國標JM系(xi)列(lie)產品，大量應用于風機系(xi)統，汽輪機組及其他重要(yao)工業領域。

彈性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。彈性聯軸器結構緊湊，傳(chuan)遞扭(niu)矩大，使用壽命長，免維護，耐(nai)高溫(wen)，耐(nai)酸堿防腐蝕，適用于高溫(wen)高速及有腐蝕工(gong)況環(huan)境的軸系傳(chuan)動(dong)。

The steel lamina coupling is an efficient flexible coupling with no back clearance and free from maintenance. Due to its unique structural design, it can achieve the perfect delivery of torque. Meanwhile, it has excellent performances, including large axial and radial compensation ability, low reply feedback force and wide thermal adaptability, etc. With different change design, it can be applied at most power transmission sites.

Rokee's RL series steel laminae coupling is a high-quality product developed independently on basis of combination of advanced products from Europe and Japan, etc. It has smaller size, larger torque of the same model, more reasonable proportioning size, large compensation scope, light weight and small rotational inertia. With modularized design, it’s easy for assembly, maintenance and replacement. Its performance far exceeds the one of JM series diaphragm coupling. It’s widely applied in the fields of fan systems, turboset and other pumps, etc.

靠背輪聯軸器用(yong)來(lai)將不同機構中的主動(dong)軸和從動(dong)軸牢固(gu)地聯接(jie)起來(lai)一(yi)同旋轉，并傳遞運(yun)動(dong)和扭矩的機械(xie)部件。有(you)時(shi)也用(yong)以聯接(jie)軸與其他零件（如齒輪、帶輪等）。

靠背輪(lun)常由兩半(ban)合成(cheng)，分(fen)別用(yong)鍵或緊配合等聯接，緊固在(zai)兩軸端，再通過(guo)某(mou)種方式(shi)將兩半(ban)聯接起來。

靠背輪聯軸(zhou)器可兼有補償兩軸(zhou)之間(jian)由于(yu)制造安裝不精確(que)、工作時的變形或熱膨(peng)脹等原(yuan)因所發生的偏移（包括軸(zhou)向(xiang)偏移、徑向(xiang)偏移、角偏移或綜合偏移）；以及緩和沖擊、吸(xi)振。

靠背輪為俗稱，專業叫(jiao)法(fa)為聯軸器以(yi)及法(fa)蘭(lan)，用(yong)于機械設備的(de)連接(jie)。
