    JMⅡJ Type Intermediate Shaft Type Diaphragm Coupling (JB/T 9147-1999)

      ●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 relies on the elastic deformation of the diaphragm to compensate 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, 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. The JZM diaphragm coupling is a high-performance flexible coupling that is promoted and applied in my country, and it has been widely adopted in industrialized countries.In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.

    Diaphragm coupling
    Diaphragm Coupling Judging from the series of reports on the special planning of equipment industry joint venture changes recently launched by this newspaper, there is an intriguing phenomenon: almost all joint venture changes occur in state-owned enterprises.But Xiao Yaqing also believes that the global aluminum ore resources are still relatively abundant.
    The pre-processes of the diaphragm coupling imported from Italy, such as raw material production, heat treatment, pickling, phosphating, etc., are centrally completed by companies such as Xinggang. The production plant can divide labor and professional production, and unify the issues of logistics, energy saving, environmental protection and pollution Centralized processing greatly reduces costs. The method of "connecting with points and connecting with lines" will be more conducive to the development of Jinggong Valve Corporation, more conducive to market development, and more conducive to serving users.

    In this way, lean production was pushed to the forefront of the application of Chinese manufacturing companies, the encoder-specific diaphragm coupling, and it was at this time that many talents were really sober and realized that while the domestic market is being eroded by foreign powers, the foreign market is also the same. Facing a complicated situation.
    The corporate operation strategy is shifting from domestic to globalization, internal to the Internet value chain, power and money to conceptual recognition, and price wars to core competitiveness. Ball screw diaphragm couplings are now being used by most domestic construction machinery manufacturers. The paint is a two-component acrylic polyurethane paint, which not only has high gloss, plump paint film, but also good weather resistance. In fact, some scientific research units and enterprises have made a lot of efforts in the recovery and recycling of scrap aluminum.
