JZM Diaphragm Coupling for Heavy Machinery

JZM type diaphragm coupling for heavy machinery is composed of several groups of diaphragms (stainless steel thin wrench) which are interlaced with two half couplings by bolts. Each group of diaphragms is composed of several overlapping diaphragms. The diaphragms are divided into connecting rods and whole diaphragms of different shapes.

  JZM type diaphragm coupling for heavy machinery is composed of several groups of diaphragms (stainless steel thin wrench) which are interlaced with two half couplings by bolts. Each group of diaphragms is composed of several overlapping diaphragms. The diaphragms are divided into connecting rods and whole diaphragms of different shapes.

  JZM type diaphragm coupling for heavy machinery compensates the relative displacement of two axes by the elastic deformation of diaphragm. It is a high performance flexible coupling with metal elastic elements. It does not need lubrication, has compact structure, high strength, long service life, no rotating clearance, and is not affected by temperature and oil pollution. It has the characteristics of acid resistance, alkali resistance and corrosion resistance. JZM type diaphragm coupling for heavy machinery has the advantages of acid resistance, alkali resistance and corrosion resistance. Shafting transmission is suitable for high temperature, high speed and corrosive medium working conditions. It is widely used in shafting transmission of various mechanical devices, such as water pump (especially high power, chemical pump), fan, compressor, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopter), high-speed power transmission system of naval vessels. After dynamic balancing, it has been widely used in high-speed transmission shafting.

  JZM type diaphragm coupling for heavy machinery has the characteristics of high mechanical strength, large load-carrying capacity, light weight, small structure size, high transmission efficiency, high transmission accuracy, good reliability, convenient assembly and disassembly, no relative sliding, no lubrication, long service life, no noise, acid-resistant, alkali-resistant and corrosion-resistant. It can be used in high temperature, low temperature, oil, water and corrosive medium working ring. Environment. JZM diaphragm coupling for heavy machinery is suitable for medium, high speed and large torque shafting transmission. As well as the shafting transmission with little change in load of various mechanical devices, it has strong versatility.
