Guangdong JM Ⅱ type non-counterbore basic diaphragm coupling

The JMⅡ type non-counterbore basic diaphragm coupling 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 made up of several pieces. The diaphragm is divided into two groups. It is a connecting rod type and a whole piece type of different shapes.Its elastic deformation compensates for the relative displacement of the connected two shafts. It is a high-performance flexible coupling with metal elastic elements. It does not require lubrication, has a compact structure, has a long service life, has no rotation gap, and is not subject to temperature and oil pollution. It has the characteristics of acid and alkali resistance. 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, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopter), naval high-speed power transmission system, after being dynamically balanced, it is applied to high-speed transmission shaft system Has become more common.Compared with the gear coupling, there is 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 the industrially developed industry. In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.Basic parameters and main dimensions of JMⅡ diaphragm coupling mm (JB/T 9147-1999)
