Diaphragm of Henan coupling

Coupling diaphragmIt is composed of several groups of diaphragms (stainless steel thin plate) which are connected with two halves of the coupling in a staggered manner with bolts. Each group of diaphragms is composed of several stacked ones. The diaphragms are divided into connecting rod type and whole piece type of different shapes.

The diaphragm coupling relies on the elastic deformation of the coupling diaphragm to compensate the relative displacement of the two shafts connected. It is a high-performance flexible coupling with metal elastic elements. It does not require lubrication, has a compact structure and a long service life. No rotation gap, not affected by temperature and oil pollution, acid and alkali resistance, suitable for shaft transmission in high temperature, high speed, and corrosive medium working conditions, and widely used in shaft transmission of various mechanical devices, 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 (helicopters), high-speed power transmission systems for ships, After dynamic balancing, it is more common to be applied to high-speed transmission shaft systems.

Use and maintenance

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, so that they will not be loosened after several shifts;

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. Long-term overload use and operation accidents should be avoided;

5. During work and operation, check whether the diaphragm coupling is abnormal. If any abnormality occurs, perform maintenance;

6. Appropriate protective measures shall be taken at each site where personal and equipment accidents may be caused by the operating diaphragm coupling.
