Flexible Laminated Membrane Couplings

The Flexible Laminated Membrane Coupling is composed of several sets of stainless steel thin plates connected in a staggered manner to the two halves of the coupling. Each set of diaphragms is composed of several stacked pieces, which are fastened to the shaft sleeve with pins. It compensates for the relative displacement of the two shafts connected by the elastic deformation of the diaphragm, which makes the Flexible Laminated Membrane Coupling no longer require lubricating oil, compact in structure, and high in strength.

Main Characteristics

• Strong compensation capability: Flexible Laminated Membrane Couplings can compensate for axial, radial, and angular offsets caused by manufacturing errors, installation errors, load deformation, and temperature rise changes between the active and driven machines. Compared with gear couplings, its angular displacement can be doubled, the reaction force is smaller during radial displacement, and the flexibility is greater.
  

• Shock absorption and noise reduction: Flexible Laminated Membrane Couplings have obvious shock absorption effects, no noise, no wear, and are suitable for environments that require quiet operation.
  

• Wide adaptability: It can work in high temperatures and harsh environments, and can operate safely under conditions of impact and vibration. At the same time, the Flexible Laminated Membrane Coupling is not affected by temperature and oil pollution, and has the characteristics of acid resistance, alkali resistance, and corrosion resistance. It is suitable for shaft transmission in high-temperature, high-speed, and corrosive medium working conditions.
  

• High transmission efficiency: The transmission efficiency of the Flexible Laminated Membrane Coupling can reach 99.86%, especially suitable for medium and high-speed high-power transmission.
  

• Simple and lightweight structure: Its structure is simple, lightweight, small in size, easy to assemble and disassemble, and does not require moving the machine or lubrication.
  

• Accurate transmission of rotational speed: The Flexible Laminated Membrane Coupling can accurately transmit rotational speed without any slip during operation, and can be used for the transmission of precision machinery.

Flexible Laminated Membrane Couplings are widely used in shaft transmission of various mechanical devices, such as water pumps, fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation, high-speed power transmission systems for ships, steam turbines, piston power mechanical transmission systems, tracked vehicles, as well as high-speed and high-power mechanical transmission systems for generator sets.

During installation, it is necessary to ensure that the axis deviation is within the allowable range to avoid deformation or damage to the coupling. After installation, all screws should be checked for looseness and safety devices such as protective covers should be ensured around the coupling.

Regularly check for loose screws and tighten them in a timely manner to prevent loosening. 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.
