Henan double diaphragm coupling

The dual-diaphragm coupling compensates the relative displacement of the two shafts connected by the elastic deformation of the diaphragm. It is a high-performance flexible coupling with metal elastic elements. It does not require lubrication, has a compact structure, has a long service life, and does not rotate. The gap is not affected by temperature and oil pollution, and has the characteristics of acid and alkali resistance. It is suitable for shaft transmission in high temperature, high speed, and corrosive medium conditions. It is widely used in shaft transmission of various mechanical devices, such as water pumps (especially It is a high-power, chemical pump), fan, compressor, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, (helicopter), high-speed power transmission system for ships, after being dynamically balanced It has been widely used in high-speed transmission shaft systems.

Double diaphragm coupling andDrum gear couplingIn contrast, there is no relative sliding, no lubrication, sealing, no noise, basically no maintenance, more convenient manufacturing, and can partially replace gear couplings.Diaphragm couplings have been widely used in industrially developed areas in Shanghai. 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 low 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 the axial and radial directions are allowed. 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 under shock and vibration conditions.

4. The transmission effect of double diaphragm coupling is good.Especially suitable for medium, high speed and high power transmission.

Maintenance method of double diaphragm coupling

1. Before installation, clean the end faces of the two shafts and check the fit of the key grooves on the end faces;

2. After the diaphragm coupling is installed, run a shift normally, check all the screws, if found to be loose, tighten them, and repeat several shifts so as not to loosen;

3. In order to prevent the fretting of the diaphragm during high-speed operation, causing microcracks and damage to the bolt holes of the diaphragm, solid lubricants such as molybdenum disulfide can be applied between the diaphragms or the surface of the diaphragm can be coated with anti-friction Layer processing

4. The diaphragm coupling should avoid long-term overload use and operation accidents;

5. When the diaphragm coupling is in operation, check whether the diaphragm coupling is abnormal, and repair it if any abnormality occurs;

6. Diaphragm couplings Take appropriate protective measures at various locations that may be caused by operating diaphragm couplings and equipment accidents.
