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)大的同(tong)型扭矩和更(geng)合理的配(pei)比尺寸，補償范圍大，質量輕轉動慣量小螺栓與膜片組的孔(kong)連接部(bu)位采用特(te)殊的彈(dan)性(xing)墊(dian)套設計(ji)，極大減小了孔(kong)緣部(bu)位應力(li)的集中，杜絕膜片的撕裂交損，延長使用壽(shou)命。

膜片彈性聯軸器采用(yong)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(yong)于風機系統，汽(qi)輪(lun)機組(zu)及其他(ta)重要(yao)工業領(ling)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(jie)構緊湊(cou)，傳遞扭(niu)矩大，使用壽(shou)命長，免維護(hu)，耐高(gao)溫(wen)，耐酸(suan)堿防腐蝕(shi)，適用于高(gao)溫(wen)高(gao)速及有腐蝕(shi)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(yong)(yong)來將(jiang)不同(tong)機(ji)構中的(de)主動(dong)軸(zhou)和從動(dong)軸(zhou)牢固(gu)地聯(lian)接起來一同(tong)旋轉，并傳遞運(yun)動(dong)和扭矩(ju)的(de)機(ji)械部(bu)件。有(you)時也用(yong)(yong)以聯(lian)接軸(zhou)與其他零(ling)件（如齒輪、帶輪等(deng)）。

靠背輪常(chang)由兩(liang)半合成，分(fen)別用(yong)鍵或緊(jin)配合等聯接，緊(jin)固在兩(liang)軸端(duan)，再(zai)通(tong)過某種方式將兩(liang)半聯接起來。

靠(kao)背輪聯軸器可兼(jian)有補償兩軸之(zhi)間由于制(zhi)造(zao)安裝不精確、工(gong)作時的變形或熱膨脹等原因所發生(sheng)的偏移（包括軸向(xiang)偏移、徑(jing)向(xiang)偏移、角偏移或綜合偏移）；以(yi)及緩(huan)和(he)沖(chong)擊(ji)、吸(xi)振。

靠(kao)背輪為俗稱(cheng)，專業叫(jiao)法為聯軸器(qi)以及法蘭，用(yong)于機械設備的連接。
