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(xiao)的(de)(de)體積，更大(da)的(de)(de)同型(xing)扭(niu)矩和更合理的(de)(de)配比(bi)尺寸(cun)，補償范圍大(da)，質(zhi)量輕轉動慣(guan)量小(xiao)螺栓與膜片組的(de)(de)孔連(lian)接部位(wei)采用特殊的(de)(de)彈性墊套設計，極大(da)減小(xiao)了孔緣部位(wei)應(ying)力的(de)(de)集中，杜絕(jue)膜片的(de)(de)撕裂(lie)交損，延(yan)長使用壽命。

膜片彈性聯軸器采用模塊化(hua)設(she)計，裝配簡單(dan)，維修更換快捷。性(xing)能(neng)遠超國標(biao)JM系(xi)列(lie)產品，大量應用于(yu)風機系(xi)統，汽輪(lun)機組及(ji)其(qi)他重要(yao)工(gong)業(ye)領(ling)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。彈性聯軸器結構緊湊，傳遞(di)扭矩大(da)，使用壽命長，免維護，耐(nai)高(gao)(gao)溫，耐(nai)酸(suan)堿防腐(fu)蝕，適用于高(gao)(gao)溫高(gao)(gao)速及(ji)有腐(fu)蝕工況環境的軸(zhou)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(tong)機(ji)構(gou)中的主動(dong)軸和從動(dong)軸牢(lao)固(gu)地聯接起來一(yi)同(tong)旋(xuan)轉，并傳遞運動(dong)和扭矩的機(ji)械部件。有(you)時也用以聯接軸與(yu)其他(ta)零件（如齒輪、帶輪等）。

靠背輪常(chang)由兩(liang)(liang)半合成，分(fen)別用鍵或(huo)緊配合等聯(lian)接，緊固在兩(liang)(liang)軸端，再通過(guo)某種方式將(jiang)兩(liang)(liang)半聯(lian)接起(qi)來。

靠背(bei)輪聯軸器可兼有補償兩軸之間(jian)由于制造安(an)裝不(bu)精確、工作(zuo)時的(de)變(bian)形或(huo)熱膨脹等原因所發生的(de)偏(pian)(pian)移(yi)(yi)（包(bao)括軸向偏(pian)(pian)移(yi)(yi)、徑向偏(pian)(pian)移(yi)(yi)、角偏(pian)(pian)移(yi)(yi)或(huo)綜合偏(pian)(pian)移(yi)(yi)）；以及緩和沖擊、吸振(zhen)。

靠背輪(lun)為俗稱，專業叫法為聯軸器(qi)以及法蘭，用于機械(xie)設備的連(lian)接(jie)。
