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(yong)有更小(xiao)的(de)體積，更大(da)(da)的(de)同(tong)型扭矩和更合理的(de)配(pei)比(bi)尺(chi)寸(cun)，補(bu)償范圍大(da)(da)，質量輕轉(zhuan)動慣量小(xiao)螺(luo)栓與膜(mo)片組的(de)孔連接部位(wei)采(cai)用特殊(shu)的(de)彈性墊套設計(ji)，極大(da)(da)減小(xiao)了孔緣(yuan)部位(wei)應力的(de)集中，杜(du)絕膜(mo)片的(de)撕裂交(jiao)損，延(yan)長使用壽命。

膜片彈性聯軸器采用模塊化設(she)計，裝配簡(jian)單，維修更(geng)換快捷。性能遠超國標JM系(xi)列產品，大量應用于風機系(xi)統(tong)，汽輪機組及其他重(zhong)要工業(ye)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(jin)湊，傳遞扭(niu)矩大，使用壽命長，免(mian)維護，耐高溫，耐酸(suan)堿防腐(fu)蝕，適(shi)用于高溫高速及有腐(fu)蝕工況環境的軸系傳動(dong)。

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機構中(zhong)的(de)主動(dong)(dong)軸和從動(dong)(dong)軸牢固地聯(lian)接(jie)起來一(yi)同旋轉，并傳遞(di)運動(dong)(dong)和扭(niu)矩的(de)機械部(bu)件。有時也用以(yi)聯(lian)接(jie)軸與其他零件（如齒輪、帶(dai)輪等）。

靠背(bei)輪(lun)常由兩半(ban)合成，分別用鍵或緊(jin)配合等聯接(jie)，緊(jin)固在(zai)兩軸(zhou)端，再通過某種方式將兩半(ban)聯接(jie)起來(lai)。

靠背(bei)輪聯軸器可兼有(you)補償兩軸之間由于制(zhi)造安裝(zhuang)不(bu)精確(que)、工(gong)作時的變(bian)形或熱膨(peng)脹等原因所發生(sheng)的偏移(yi)（包括軸向(xiang)偏移(yi)、徑(jing)向(xiang)偏移(yi)、角偏移(yi)或綜合偏移(yi)）；以及緩和沖擊、吸振。

靠背(bei)輪為俗稱，專業(ye)叫法為聯軸器以(yi)及法蘭，用(yong)于機械設備(bei)的(de)連接。
