JMIJ connected to the intermediate shaft type doubleDiaphragm couplingIt consists of several sets of diaphragms (stainless steel thin plate) with bolts staggered with two halvesCouplingConnected, each group of diaphragms is made up of several sheets, and the diaphragms are divided into connecting rod type and different shapes of whole piece type.

JMIJ connects intermediate shaft type double diaphragmFlexible couplingRelying on the elastic deformation of the diaphragm to compensate for the relative displacement of the two shafts connected, it is a high-performance flexible coupling with metal elastic elements. It does not require lubrication, has a compact structure, high strength, long service life, no rotation gap, and no Affected by temperature and oil pollution, it has the characteristics of acid resistance, alkali resistance, and corrosion resistance. It is suitable for shaft transmission in high temperature, high speed, and corrosive medium conditions. It is widely used in shaft 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 (helicopters), high-speed power transmission systems for ships, dynamic balance Later, it has been widely used in high-speed transmission shaft systems.

JMIJ connects intermediate shaft type double diaphragmFlexible couplingCompared 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 couplingThe application in developed countries in the world has been very common. In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.

Protective device of JMIJ connecting intermediate shaft type double diaphragm elastic coupling:

XNUMX. The coupling guard is usually provided by the buyer.Therefore, this part of the content does not belong to the requirements of the coupling.
XNUMX. Basic requirements
1. The buyer or contractor shall specify the type of protective device required.
2. Each coupling should have a protective device to close the coupling and the shaft to prevent people or objects from entering this dangerous area when the unit is running.
3. The protective device should be easy to disassemble, so that the connected machine will not be affected when the coupling is overhauled and maintained.
4. The structure of the protective device must have sufficient rigidity. When bearing a static load of 900N, its deflection shall not exceed 0.0005 times the unsupported length of the protective device.
5. The protective device of the coupling that needs lubrication should be sealed.
6. When necessary, the protective device should be equipped with anti-turbulence baffle to reduce the influence of gas or oil whirlpool.
7. If necessary, the protective device can be made of materials that will not produce sparks due to friction.
XNUMX. Flange-connected cylindrical shell protection devices are usually used on medium and high-speed gear couplings and diaphragm couplings.
1. The structure of the protective device is cylindrical and split along the axial direction. The protective device is connected to the corresponding equipment in the unit by flanges at both ends.There should be an expansion joint at one end of the protective device, and an O-ring seal should be installed at the expansion joint.
2. If the coupling is working under corrosive conditions and needs protection, the protective device must be equipped with pipe joints to allow access to dry air or inert gas.
3. Protective device for continuous lubrication of the coupling
(A) Each fuel injection nozzle must be screwed to the protective device in the appropriate direction, so that the oil is sprayed in the direction of transfer.If the unit is running in forward and reverse directions, the oil is injected along the axial direction.The oil nozzle or oil pipe is not allowed to collide with the coupling.
(B) The protective device shall remain airtight for at least 3 years.
(C) IfCouplingIf the return oil cannot flow smoothly into the oil drain pipe of the connected machine, a flanged oil drain connection must be provided under the protective device.
(D) If specified by the buyer, set up a transparent viewing window on the protective device so that the working condition of each injector can be checked during the operation of the coupling.
