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)(geng)小的(de)體積，更(geng)(geng)大的(de)同型扭矩(ju)和(he)更(geng)(geng)合理的(de)配比尺(chi)寸，補償范圍大，質量輕轉動慣量小螺栓(shuan)與膜片(pian)組(zu)的(de)孔(kong)連接部(bu)位采用特殊的(de)彈性墊套設計，極(ji)大減小了孔(kong)緣部(bu)位應力的(de)集中，杜絕膜片(pian)的(de)撕裂交損(sun)，延長使用壽命。

膜片彈性聯軸器采(cai)用(yong)(yong)模塊化設計，裝(zhuang)配簡單，維(wei)修更(geng)換快(kuai)捷。性能遠超(chao)國(guo)標JM系列產品，大量(liang)應用(yong)(yong)于風(feng)機(ji)系統，汽(qi)輪機(ji)組及其(qi)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(chuan)遞扭(niu)矩大，使用(yong)壽命長(chang)，免維護，耐(nai)高(gao)(gao)溫，耐(nai)酸堿(jian)防腐蝕，適(shi)用(yong)于高(gao)(gao)溫高(gao)(gao)速及有腐蝕工況(kuang)環境的軸系傳(chuan)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(lai)將(jiang)不同機(ji)構中(zhong)的主動軸(zhou)和(he)從(cong)動軸(zhou)牢固地聯(lian)接起來(lai)一同旋(xuan)轉，并傳遞(di)運動和(he)扭矩的機(ji)械部(bu)件(jian)。有時也用以(yi)聯(lian)接軸(zhou)與其他(ta)零件(jian)（如齒輪(lun)、帶輪(lun)等）。

靠背輪常由兩(liang)半(ban)合成，分別用鍵或緊配合等聯接(jie)，緊固(gu)在兩(liang)軸(zhou)端(duan)，再通過某(mou)種方式(shi)將兩(liang)半(ban)聯接(jie)起(qi)來。

靠背輪聯軸器可兼有(you)補償(chang)兩軸之(zhi)間由于制造(zao)安裝不精確、工(gong)作時的(de)變形或(huo)熱膨脹等原因所發生的(de)偏(pian)移(yi)(yi)(yi)（包括(kuo)軸向偏(pian)移(yi)(yi)(yi)、徑向偏(pian)移(yi)(yi)(yi)、角偏(pian)移(yi)(yi)(yi)或(huo)綜合偏(pian)移(yi)(yi)(yi)）；以及(ji)緩和沖擊、吸(xi)振。

靠背輪為俗稱(cheng)，專業叫法為聯(lian)軸器以及法蘭，用于機(ji)械(xie)設(she)備的連接。
