RLAD Standard Double Section Metal Diaphragm Coupling

The classic design of metal flexible diaphragm couplings is a reliable choice for medium to low speed applications.

The standard double diaphragm coupling is a high-performance metal elastic element flexible coupling. The 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, and the diaphragms are divided into connecting rod type and integral pieces of different shapes. It compensates for the relative displacement of the two axes connected by the elastic deformation of the membrane.

Main characteristics

• Strong compensation capability: The double Plate coupling has a strong ability to compensate for the misalignment of two axes. Compared with the gear coupling, its angular displacement compensation capability can be doubled. When there is radial displacement, the reaction force is small and the flexibility is large, allowing for certain axial, radial, and angular displacements.
  

• Shock absorption and noise reduction: This coupling has a significant shock absorption effect, no noise, no wear, and is suitable for various occasions that require quiet and smooth operation.
  

• High temperature and corrosion resistance: The Shim Pack coupling can adapt to high temperatures (-80~300 ℃) and harsh environments, and has the characteristics of acid and alkali corrosion resistance. It can operate safely under impact and vibration conditions.
  

• High transmission efficiency: Its transmission efficiency can reach 99.86%, especially suitable for medium and high-speed high-power transmission.
  

• Simple structure and light weight: The Steel Laminae coupling has a simple structure, light weight, small volume, easy assembly and disassembly, and does not require moving the machine body for assembly and disassembly, and does not require lubrication.

Double Metal diaphragm couplings are widely used for shaft transmission in various mechanical devices, such as water pumps (especially high-power and chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopter), high-speed power transmission systems for ships, and high-speed and high-power mechanical transmission systems for generator sets.

Installation method: The installation of the Laminated Membrane coupling requires following certain steps and precautions, such as ensuring that the axis deviation is within the allowable range, using a torque wrench to tighten screws to the specified torque, etc.

Maintenance: Regularly check whether the screws are loose and tighten them in a timely manner; In order to prevent micro motion wear of the diaphragm during high-speed operation, solid lubricants such as molybdenum disulfide can be applied between the diaphragms or the diaphragm surface can be treated with a wear-resistant coating.

The standard Flexible Membrane coupling plays an important role in the shaft transmission of various mechanical devices due to its unique structure and superior performance.
