Jiangsu 304 stainless steel diaphragm

304不锈钢膜片厚度一般为0. 2mm～0. 6mm, 材质为1Cr18Ni9TI，膜片形状主要有圆环式、轮幅式、连杆式、多边式和束腰式。

Flexible metal diaphragmCouplingThe structure is mainly composed of metal diaphragm group (diaphragm), half coupling, intermediate section, compression element, bolt, lock nut, washer, etc.

The working principle is: the torque is input from the half coupling of the active end, and the torque is transmitted to the diaphragm group through the main torsion high-strength bolts arranged at intervals along the circumference, and then the diaphragm group is transmitted to the middle section through the high-strength bolts. , And also output by the diaphragm set at the other end, high-strength bolts and the driven end half coupling.The metal diaphragm is the key component of the flexible coupling. It is composed of a large number of thin metal diaphragms laminated to form a diaphragm group, through which torque and movement are transmitted.

The 304 stainless steel diaphragm compensates for 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, high strength, and long service life. Rotational clearance is not affected by temperature and oil pollution. It 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 high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), naval high-speed power transmission systems, 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, repeat this for several shifts to ensure that they will not 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. 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 various sites where personal and equipment accidents may be caused by the operating diaphragm coupling.
