MI typeDiaphragm coupling (JB/T 9147-1999)
Custom-made various splits, integral coupling diaphragms (1-7 days construction period)
●The diaphragm coupling is composed of several groups of diaphragms (stainless steel thin plate) which are alternately connected with the two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. The diaphragms are divided into connecting rod type and different The shape of the whole piece.
●The diaphragm coupling compensates for the relative displacement of the two shafts connected by the elastic deformation of the diaphragm. It is a high-performance flexible coupling with metal elastic elements. It does not require lubrication, has a compact structure, high strength and long service life. , No rotation gap, not affected by temperature and oil pollution, with acid resistance, alkali resistance, and corrosion resistance. It is suitable for high temperature, high speed, and corrosive medium shafting. It is widely used in shafting of various mechanical devices. Transmission, 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 (helicopters), high-speed naval power The transmission system, after being dynamically balanced, is commonly used in high-speed transmission shaft systems.
●Compared with the gear coupling, the diaphragm coupling has no relative sliding, no lubrication, sealing, no noise, basically no maintenance, more convenient to manufacture, and can partially replace the gear coupling.Diaphragm couplings have been widely used in industrially developed countries in the world. In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.
