How can the service life of the diaphragm coupling be extended

The diaphragm coupling is made up of several groups of diaphragm (stainless steel thin plate) interlaced with bolts and the two halves of the coupling, each group of diaphragm by a number of overlapping, diaphragm is divided into connecting rod type and different shapes of the whole piece. Is a high-performance metal flexible coupling components elastic, no lubrication, structure is compact, high intensity, long service life, no rotating clearance, not influenced by temperature and oil pollution, has the characteristics of acid and alkali resistance, corrosion resistance, suitable for high temperature, high speed, working condition of a corrosive medium environment of shaft drive, shaft drive is widely used in all kinds of machinery, 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 is applied to high-speed drive shafting has been more common. Our company specializes in the production of universal coupling

The vulnerable part of the diaphragm coupling is the diaphragm assembly. The service life of the diaphragm assembly determines the service life and mission efficiency of the coupling. The diaphragm coupling produced in China has a certain gap with foreign products in terms of appearance quality and service life. Therefore, researchers on the diaphragm coupling research from the practical damage of the diaphragm group and theoretical analysis, the main damage of the diaphragm assembly appears in the hinge point of the diaphragm group. This is because when there is angular displacement and axial displacement between the power machine and the task machine, additional stress will occur to the diaphragm group in the diaphragm coupling connecting the power machine and the task machine. When the diaphragm coupling is in high speed operation or repeated positive rotation, the diaphragm group accepts the effect of alternating stress and is easy to be destroyed.

Compared with the tooth coupling, diaphragm coupling has no relative sliding, no need for lubrication, sealing, no noise, basic need not maintenance, more convenient manufacturing, can partly replace the tooth coupling. Diaphragm coupling has been widely used in developed areas. In practical application, intermediate shaft type is generally adopted to improve the performance of offset of two axes.
