膜片联轴器与柱销联轴器哪个好用一点

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.

柱销联轴器是利用一端套有弹性套（橡胶材料）的柱销，装在两半联轴器凸缘孔中，以实现两半联轴器的联接。

弹性柱销联轴器是一种结构简单制造容易，无需润滑，装拆弹性柱销便捷的传动基础件，利用两个带法兰孔的半联和置于起重的非金属弹性柱销来传递扭矩，适用于中低速和中低扭矩场合。

弹性柱销齿式联轴器采用非金属弹性柱销和两个带齿形半联以及一个外圈的齿形套环设计，利用非金属弹性的变形来传递扭矩同时缓冲减震，补偿角向位移。

弹性套柱销联轴器设计简单巧妙，适用性较广的联轴器，利用带弹性套的柱销联接两个带销孔的半联，实现扭矩传递的同时兼具较大的角向补偿，同时减震缓冲性能良好，可以用在速度较快的场合，无需润滑，销套更换便捷。

The pin gear coupling is designed with non-metallic flexible pin, two toothed semi-couplings and a toothed sleeve ring with an outer ring. It uses non-metallic flexible deformation to transfer torque and cushion shock and compensate angular displacement. The flexible pin coupling is a basic transmission parts that has simple structure, needs no lubrication, and is easy to manufacture, install and disassemble the flexible pin. It uses two semi-couplings with flange holes and a non-metallic flexible pin for crane to transmit torque, suitable for low-to-medium speed and low-to-medium torque occasions. The design of the elastic sleeve pin coupling is simple and clever in design and has wide applicability. It uses the pin with elastic sleeve to connect two semi-couplings with pin holes to realize torque transmission and larger angular compensation. At the same time, Pin and bush couplings has good shock absorption and buffering performance, which can be used in high-speed occasions without lubrication and requiring easy pin sleeve replacement.
