RL系列膜片聯軸器是結合歐洲與日本等優(yōu)質產品基礎之上獨立開發(fā)的高品質產品。膜片式聯軸器擁有更小的體積，更大的同型扭矩和更合理的配比尺寸，補償范圍大，質量輕轉動慣量小螺栓與膜片組的孔連接部位采用特殊的彈性墊套設計，極大減小了孔緣部位應力的集中，杜絕膜片的撕裂交損，延長使用壽命。

膜片彈性聯軸器采用模塊化設計，裝配簡單，維修更換快捷。性能遠超國標JM系列產品，大量應用于風機系統，汽輪機組及其他重要工業(yè)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，傳遞扭矩大，使用壽命長，免維護，耐高溫，耐酸堿防腐蝕，適用于高溫高速及有腐蝕工況環(huán)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.

凸緣聯軸器屬于剛性聯軸器，是把兩個帶有凸緣的半聯軸器用普通平鍵分別與兩軸連接，然后用螺栓把兩個半聯軸器連成一體，以傳遞運動和轉矩。這種聯軸器有兩種主要的結構形式：靠鉸制孔用螺栓來實現兩軸對中和靠螺栓桿承受擠壓與剪切來傳遞轉矩；靠一個半聯軸器上的凸肩與另一個半聯軸器上的凹槽相配合而對中。連接兩個半聯軸器的螺栓可以采用A級和B級的普通螺栓，轉矩靠兩個半聯軸器結合面的摩擦力矩來傳遞。凸緣聯軸器結構簡單，制造方便，成本較低，工作可靠，裝拆、維護均較簡便，傳遞轉矩較大，能保證兩軸具有較高的對中精度，一般常用于載荷平穩(wěn)，高速或傳動精度要求較高的軸系傳動。凸緣聯軸器不具備徑向、軸向和角向補償。剛性聯軸器是一種扭轉剛性的聯軸器，即使承受負載時也無任何回轉間隙，即便是有偏差產生負荷時，剛性聯軸器還是剛性傳遞扭矩。
