The dual-diaphragm coupling compensates for the relative displacement of the connected two shafts by the elastic deformation of the diaphragm. It is a high-performance flexible coupling with metal elastic elements, which does not require lubrication, has a compact structure, high strength and long service life. , No rotation gap, not affected by temperature and oil pollution, with acid resistance, alkali resistance, and corrosion resistance. It is suitable for high temperature, high speed, and corrosive medium shafting. It is widely used in shafting of various mechanical devices. Transmission, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopter), high-speed naval power The transmission system, after being dynamically balanced, is commonly used in high-speed transmission shaft systems.
Compared with the gear coupling, the double diaphragm coupling has no relative sliding, does not need lubrication, sealing, noise, basically does not require maintenance, and is more convenient to manufacture. It can partially replace the gear coupling.Diaphragm couplings have been widely used in industrially developed countries in the world. In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.
The dual-diaphragm coupling can compensate the axial, radial and angular deviations between the driving machine and the driven machine due to manufacturing errors, installation errors, load-bearing deformation, and the effects of temperature rise changes.The diaphragm coupling is a flexible coupling with a metal elastic element. It relies on the metal coupling diaphragm to connect the main and driven machines to transmit torque. It has the advantages of elastic vibration damping, no noise, and no need for lubrication. It is today's replacement tooth Ideal product for type couplings and general couplings.
The main characteristics of the double diaphragm coupling
1. The double diaphragm coupling has a strong ability to compensate for the misalignment of the two axes. Compared with the gear coupling, the angular displacement can be doubled, the reaction force is small during radial displacement, the flexibility is large, and a certain axial direction is allowed. , Radial and angular displacement.
2. The world of double diaphragm couplings. Diaphragm couplings have obvious shock absorption, no noise and no wear.
3. It is suitable for working in high temperature (-80 300) and harsh environment, and can move safely under shock and vibration conditions.
4. The transmission efficiency of the double diaphragm coupling is high, up to 99.86%.Especially suitable for medium, high speed and high power transmission
