Rokee® Customized Flexible Double Diaphragm Coupling for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
The flexible double diaphragm coupling is a high-performance metal elastic element flexible coupling. The flexible double diaphragm coupling is composed of several sets of diaphragms (stainless steel thin plates) connected to the two halves of the coupling by bolts in a staggered manner. Each set of diaphragms is composed of several stacked pieces. It compensates for the relative displacement of the two axes connected by the elastic deformation of the membrane, such as axial displacement, radial displacement, and angular displacement.
Characteristics and advantages
Compact structure: The flexible double diaphragm coupling has a compact design, small volume, light weight, and is easy to install and maintain.
High strength and long service life: Using stainless steel sheet as the membrane material, it has high strength and corrosion resistance, and a long service life.
No rotational clearance: Due to the elastic deformation of the diaphragm, the flexible double diaphragm coupling has no rotational clearance during operation, resulting in high transmission efficiency.
Temperature and corrosion resistance: Suitable for shaft transmission in high temperature and corrosive medium working conditions, it has the characteristics of acid resistance, alkali resistance, and corrosion resistance.
Shock absorption and noise reduction: It has a significant shock absorption effect and operates without noise or wear.
Easy to install: No lubrication required, easy to assemble and disassemble, no need to move the machine body for loading and unloading.
Flexible double diaphragm couplings are widely used in shaft transmission systems of various mechanical devices, such as water pumps, fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, as well as high-speed power transmission systems for aviation and naval vessels. Especially in situations where high power transmission, high-speed operation, and the presence of corrosive media are required, flexible double diaphragm couplings have significant advantages.
When installing a flexible double diaphragm coupling, the following points should be noted:
Proper installation of bolts: Bolts are one of the important components of double diaphragm couplings, and their correct installation directly affects the performance, service life, and safety of the coupling. Therefore, installation should be carried out in the correct direction and method, and ensure that the bolt components perform well.
Check the gap between the diaphragm: Before installation, it is necessary to check whether the gap between the diaphragm and the intermediate extension joint meets the requirements to avoid problems such as diaphragm distortion and deformation during installation and operation.
Maintain cleanliness: During installation, the coupling and its connecting components should be kept clean to avoid impurities and dirt from affecting the performance of the coupling.
Although the flexible double diaphragm coupling has the characteristic of maintenance free, regular inspection and maintenance are still required during long-term operation. The main inspection contents include the tightening of bolts, the wear of diaphragms, and the overall operating status of the coupling. If any abnormal situation is found, it should be dealt with and replaced in a timely manner to avoid damage to the equipment.
Flexible double diaphragm couplings play an important role in mechanical transmission systems due to their unique structure and performance advantages. In the selection and use process, its characteristics and requirements should be fully considered to ensure the normal operation and long-term stability of the equipment.
