The JZM type heavy-duty machinery diaphragm coupling is composed of several sets of diaphragms (stainless steel thin plates) connected to the two halves of the coupling in a staggered manner with bolts. Each set of diaphragms is composed of several stacked pieces, and the diaphragms are divided into connecting rod type and integral pieces of different shapes.

JZM type diaphragm coupling for heavy machinery compensates for the relative displacement of the two shafts by the elastic deformation of the diaphragm. It is a high-performance metal elastic element flexible coupling that does not require lubrication, has a compact structure, high strength, long service life, no rotational clearance, and is not affected by temperature and oil pollution. It has the characteristics of acid resistance, alkali resistance, and corrosion resistance, and is suitable for shaft transmission in high-temperature, high-speed, and corrosive medium working environments. It is widely used in shaft transmission of various mechanical devices, such as water pumps (especially high-power and chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), and high-speed power transmission systems for ships. After balancing, it has been widely applied to high-speed transmission shaft systems.

The JZM type diaphragm coupling for heavy machinery has high mechanical strength, large load-bearing capacity, light weight, small structural dimensions, high transmission efficiency and accuracy, good reliability, easy assembly and disassembly, and has the characteristics of no relative sliding, no need for lubrication, long service life, no noise, acid resistance, alkali resistance, corrosion resistance, etc. It can be used in high temperature, low temperature, and working conditions with oil, water, and corrosive media. Suitable for medium, high-speed, and high torque shaft transmission. And the shaft transmission with minimal load changes in various mechanical devices has strong universality.
