传动座膜片联轴器标准

RL系列膜片联轴器是结合欧洲与日本等优质产品基础之上独立开发的高品质产品。膜片式联轴器拥有更小的体积，更大的同型扭矩和更合理的配比尺寸，补偿范围大，质量轻转动惯量小螺栓与膜片组的孔连接部位采用特殊的弹性垫套设计，极大减小了孔缘部位应力的集中，杜绝膜片的撕裂交损，延长使用寿命。

膜片弹性联轴器采用模块化设计，装配简单，维修更换快捷。性能远超国标JM系列产品，大量应用于风机系统，汽轮机组及其他重要工业领域。

弹性膜片联轴器在传递扭矩的同时通过弹性膜片的的变形来补偿轴向和角向的位移，是一种高性能的金属弹性挠性联轴器。弹性联轴器结构紧凑，传递扭矩大，使用寿命长，免维护，耐高温，耐酸碱防腐蚀，适用于高温高速及有腐蚀工况环境的轴系传动。

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.

靠背轮联轴器用来将不同机构中的主动轴和从动轴牢固地联接起来一同旋转，并传递运动和扭矩的机械部件。有时也用以联接轴与其他零件（如齿轮、带轮等）。

靠背轮常由两半合成，分别用键或紧配合等联接，紧固在两轴端，再通过某种方式将两半联接起来。

靠背轮联轴器可兼有补偿两轴之间由于制造安装不精确、工作时的变形或热膨胀等原因所发生的偏移（包括轴向偏移、径向偏移、角偏移或综合偏移）；以及缓和冲击、吸振。

靠背轮为俗称，专业叫法为联轴器以及法兰，用于机械设备的连接。
