JZM diaphragm coupling for heavy machinery

Diaphragm couplingBecause of its performance, it is favored by construction machinery and rolling machinery. Although diaphragm couplings can fail or even become scrap due to various reasons, it is of great significance to study the causes of failure.Diaphragm damage is the failure of the couplingMain form, damaged diaphragm ring.The fault tree analysis method is a common and practical systematic analysis method in engineering. This method is simple, intuitive and flexible, and is suitable for failure analysis of diaphragm couplings.The author will use this analysis method to analyze the failure mechanism of the diaphragm coupling according to the specific failure mode of the diaphragm coupling in the engineering practice.
The JZM type diaphragm coupling for heavy machinery 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 composed of several pieces stacked together. The diaphragm is divided into Rod type and whole piece type with different shapes.
JZM type diaphragm coupling device for heavy machinery has large load capacity, light weight, small structure size, transmission efficiency and transmission, good performance, convenient assembly and disassembly, and has no relative sliding, no lubrication, long service life, no Noise, acid and alkali resistance, etc., can be used in high temperature, low temperature, oil, water and corrosive medium working conditions, suitable for medium, high speed, large torque shaft transmission, and the load of various mechanical devices has little change The shafting transmission, versatility.
The JZM diaphragm coupling for heavy machinery uses the elastic deformation of the diaphragm to compensate for the relative displacement of the connected two shafts. It does not require lubrication, has a compact structure, has a long service life, has no rotation gap, and is not affected by temperature and oil pollution. It has the characteristics of acid and alkali resistance, suitable for high temperature, high speed, and corrosive medium shafting transmission. It is widely used for shafting 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 (helicopter), naval high-speed power transmission system, after dynamic balance applied to high-speed transmission shaft system has been compared universal.
The diaphragm coupling is a mechanical component that connects the driving part and the driven mechanism to rotate together and transfer energy and movement.Couplings can be divided into rigid couplings and elastic couplings. Rigid couplings are usually used in low-speed and heavy-duty situations, and their main function is to transmit larger power; while elastic couplings are mainly used for high-speed rotors. The system uses elastic elements or specific structures to adjust and compensate for misalignment caused by manufacturing, installation and temperature changes. At the same time, general elastic couplings have the function of vibration isolation. In 1982, my countryTaiwan's high-power high-speed diaphragm flexible coupling was successfully tested in Southern Power Company. This type of coupling has become a hot spot in the domestic engineering community due to its good performance.
The diaphragm coupling has no lubrication, long service life, and compensation capabilities.It transmits torque through flexible steel sheets, and has angular, axial, and radial displacement compensation capabilities and shock absorption.The diaphragm is easy to assemble and disassemble, without lubrication, and can be ideally applied to various working conditions.
