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。膜片式聯軸器擁有更(geng)小的體積，更(geng)大(da)的同(tong)型扭矩和更(geng)合理的配比尺寸(cun)，補(bu)償范圍大(da)，質量輕轉動慣量小螺(luo)栓與膜片組的孔連接部位(wei)采用特殊的彈性墊(dian)套設計，極大(da)減小了孔緣部位(wei)應力的集中(zhong)，杜(du)絕膜片的撕裂交(jiao)損，延(yan)長使(shi)用壽命(ming)。

膜片彈性聯軸器采用模塊化設計，裝配簡單(dan)，維(wei)修更換快捷(jie)。性能遠超國標JM系列產(chan)品，大量應用于風機系統(tong)，汽輪機組及其他重要工(gong)業領域(yu)。

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(jie)構緊(jin)湊，傳遞扭矩大，使用壽命(ming)長，免維(wei)護，耐高溫(wen)，耐酸堿防腐蝕，適(shi)用于高溫(wen)高速(su)及(ji)有腐蝕工況環境的軸系傳動。

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.

靠背輪聯軸器用來將不同機(ji)構中(zhong)的主動軸和從動軸牢(lao)固地(di)聯接起來一同旋轉(zhuan)，并傳遞(di)運動和扭矩的機(ji)械部件(jian)。有時也用以(yi)聯接軸與其他零件(jian)（如(ru)齒輪、帶輪等）。

靠背輪常由兩(liang)(liang)半(ban)合成，分別用鍵或(huo)緊配合等(deng)聯(lian)(lian)接，緊固在兩(liang)(liang)軸(zhou)端，再通過某(mou)種方式將兩(liang)(liang)半(ban)聯(lian)(lian)接起來。

靠背輪聯(lian)軸(zhou)器可兼有補償(chang)兩軸(zhou)之間(jian)由于制造(zao)安裝不精確、工作(zuo)時的變(bian)形或(huo)熱膨脹等原因所發生的偏(pian)(pian)(pian)移（包括(kuo)軸(zhou)向偏(pian)(pian)(pian)移、徑向偏(pian)(pian)(pian)移、角偏(pian)(pian)(pian)移或(huo)綜合(he)偏(pian)(pian)(pian)移）；以及緩和沖擊、吸振。

靠背輪為俗稱，專(zhuan)業(ye)叫法(fa)為聯軸器(qi)以及法(fa)蘭(lan)，用于機(ji)械設備的連接(jie)。
