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.

萬向聯軸器采用十字軸承聯接兩端聯接法蘭，可以傳遞完全不在同一軸線的扭矩，對角向的補償可達25?以上，采用花鍵聯接可以大距離地補償軸向位移。萬向軸承載能力高，傳動效率優異，在現代工業領域被廣泛采用。

SWP十字萬向聯軸器采用剖分式叉頭布局，與SWC十字萬向聯軸器使用的場合相近，主要運用在重載大型裝備領域，回轉直徑可達1200mm。

SWC十字萬向聯軸器采用整體式叉頭布局，主要用于軋鋼機械，起重運輸機械等其他重型裝備領域，回轉直徑可到1600mm，扭矩傳遞距離可達30m以上，是運用相當廣泛的萬向聯軸器。

萬向節聯軸器的不同軸可能是徑向位移，傾斜或兩者兼而有之。測量同軸度應在十字軸萬向聯軸器端面和圓周上均勻分布的四個位置進行。十字軸式萬向聯軸器聯接的機泵在安裝過程中都不可避免地要進行同軸度的調整，使對輪既同心又平行，否則將影響機泵使用效率或造成設備運行事故。

For nearly 30 years, Rokee has always adhered to the road of innovation. Using our full understanding of this unique product and years of manufacturing experience, we have continuously optimized the design and manufacture of our Universal Joint Shaft products to supply various industrial fields with our Cost-effective and high-performance products. Our products are widely used and have many impressive records. From micro Universal Shafts for modern logistics, artificial intelligence machinery, light products used in the paper industry, high speed and high performance products for engineering and railway vehicles, to super heavy duty products used in metallurgical rolling system systems, Rokee has won us with mature products and quality Long-term trust of customers, widely exported to Europe, America and other parts of the world.

We have 4 series of nearly 100 standard models and various extended design Universal Joint Couplings based on this for our customers to choose, Torque from *** to ***, diameter from 58mm to 1200mm, ranging from light products to super heavy-duty products, the service field covers almost all transmission occasions. All standard products of Rokee are optimized design products based on the combination of decades of experience and computer design technology. The Universal Couplings we are proud of are not only different from the national technical standards of China but also the standards of other manufacturers in the world. Unique design ideas and make perfection more perfect sprit drive our products find a better balance between lower price and rotational and transmission torque performance. Rokee's standardized products also mean faster delivery and easier spare parts availability as well as quick maintenance service. The cardan shaft products used in important equipment and core industrial fields have not only undergone careful design, but also comprehensive torque, stiffness, balance performance and life tests.

靠背輪聯軸器用來將不同機構中的主動軸和從動軸牢固地聯接起來一同旋轉，并傳遞運動和扭矩的機械部件。有時也用以聯接軸與其他零件（如齒輪、帶輪等）。

靠背輪常由兩半合成，分別用鍵或緊配合等聯接，緊固在兩軸端，再通過某種方式將兩半聯接起來。

靠背輪聯軸器可兼有補償兩軸之間由于制造安裝不精確、工作時的變形或熱膨脹等原因所發生的偏移（包括軸向偏移、徑向偏移、角偏移或綜合偏移）；以及緩和沖擊、吸振。

靠背輪為俗稱，專業叫法為聯軸器以及法蘭，用于機械設備的連接。
