MOREJZMJ type diaphragm coupling for heavy machinery
The JZMJ type diaphragm coupling for heavy machinery is composed of several groups of diaphragms (stainless steel thin plate) that are alternately connected to the two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. The diaphragm is divided into Rod type and different shapes of the whole piece type.
JZMJ type diaphragm couplingCoupling diaphragmIt is a kind of high-performance flexible coupling with metal elastic element, which does not need lubrication, has a compact structure, high strength, long service life, no rotation gap, and is not affected by temperature and Influenced by oil pollution, it is suitable for shafting transmission in high temperature, high speed, and corrosive medium conditions. It is widely used for shafting transmission of various mechanical devices, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulics High-speed power transmission systems of machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), and naval vessels are commonly used in high-speed drive shaft systems after dynamic balancing.
The JZMJ diaphragm coupling for heavy machinery produced by our factory 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 no relative sliding , No lubrication, long service life, no noise, can be used in high temperature, low temperature, oil, water and corrosive medium working environment.Suitable for medium, high speed and large torque shaft transmission.As well as the shaft transmission with little change in load of various mechanical devices, it has strong versatility.
