Detailed introduction of diaphragm coupling

Published: 2017-12-15

Diaphragm couplingIt is a kind of coupling model. Here we will take you to understand the diaphragm coupling in detail.

Several groups of diaphragms (stainless steel thin plate) are alternately connected with the two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. The diaphragms are divided into connecting rod type and different shape of the whole piece type.

The diaphragm coupling relies on the elastic deformation of the diaphragm to compensate for the relative displacement of the connected two shafts. 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 resistance, alkali resistance, and corrosion 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), high-speed naval power transmission systems, After balancing, it is relatively common to apply to high-speed transmission shafts.

JZMJ type diaphragm coupling device for heavy machinery, large load capacity, light weight, small structure size, high transmission efficiency and transmission accuracy, good performance, convenient assembly and disassembly, and has no relative sliding, does not need lubrication, and has a long service life , No noise, acid and alkali resistance, etc., can be used in high temperature, low temperature, oil, water and corrosive media working environment.Suitable for medium, high speed and large torque shaft transmission.As well as the shafting transmission with little change in the load of various mechanical devices, it has strong versatility.

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 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. 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.
