膜片式联轴器是刚性轴承吗

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.

凸缘联轴器属于刚性联轴器，是把两个带有凸缘的半联轴器用普通平键分别与两轴连接，然后用螺栓把两个半联轴器连成一体，以传递运动和转矩。这种联轴器有两种主要的结构形式：靠铰制孔用螺栓来实现两轴对中和靠螺栓杆承受挤压与剪切来传递转矩；靠一个半联轴器上的凸肩与另一个半联轴器上的凹槽相配合而对中。连接两个半联轴器的螺栓可以采用A级和B级的普通螺栓，转矩靠两个半联轴器结合面的摩擦力矩来传递。凸缘联轴器结构简单，制造方便，成本较低，工作可靠，装拆、维护均较简便，传递转矩较大，能保证两轴具有较高的对中精度，一般常用于载荷平稳，高速或传动精度要求较高的轴系传动。凸缘联轴器不具备径向、轴向和角向补偿。刚性联轴器是一种扭转刚性的联轴器，即使承受负载时也无任何回转间隙，即便是有偏差产生负荷时，刚性联轴器还是刚性传递扭矩。
