JMJ type diaphragm coupling

● DiaphragmCouplingDiaphragm couplingRelying on the elastic deformation of the diaphragm to compensate 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, high strength, long service life, no rotation gap, and no Affected by temperature and oil pollution, it 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 power transmission systems for ships, dynamic balance Later, it has been widely used in high-speed transmission shaft systems.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.Diaphragm couplings have been widely used in industrially developed countries in the world.

●The diaphragm coupling is composed of several groups of diaphragms (stainless steel thin plate) which are alternately connected with two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. The diaphragms are divided into rod type and different shapes . The whole piece.
● JZMJ diaphragm for heavy machineryCouplingIt has high mechanical strength, large carrying capacity, light weight, small structure size, high transmission efficiency and transmission accuracy, good reliability, convenient assembly and disassembly, and has no relative sliding, no lubrication, long service life, no noise, acid resistance, Alkali, anti-corrosion and other characteristics, 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 shaft transmission of various mechanical devices with little change in load, it is extremely versatile.

● 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, all screws must be checked for normal operation in one shift. If they are found to be loose, they must be tightened. Repeat this for several shifts to ensure that they will not be loosened;

　　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, a solid lubricant such as molybdenum disulfide can be applied between the diaphragms or the surface of the diaphragm can be coated with anti-friction Layer processing; high-speed diaphragm coupling

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

　　5. During work and operation, check whether the diaphragm coupling is abnormal, and repair it if any abnormality occurs;
　 6. Appropriate protective measures must be taken at various sites where personal and equipment accidents may be caused by the operating diaphragm coupling.
