JMIJ type connecting intermediate shaft type diaphragm coupling
JMIJ type with intermediate shaft typeDiaphragm couplingMainly rely on the elastic metal diaphragm in the middle of the coupling to transmit the torque between the two shafts. It has the advantages of vibration absorption, no wear and no maintenance. It is an ideal product to replace gear couplings and general couplings today. .
Main features of JMIJ type diaphragm coupling with intermediate shaft:
1. To compensate for the misalignment of the two axes, the angular displacement can be doubled compared with the gear coupling, the reaction force is small during radial displacement, the flexibility is large, and some axial, radial and angular displacement are allowed.
2. It has obvious shock absorption, no noise and no wear.
3. Transmission can reach 99.86%.Especially suitable for medium, high speed and high power transmission.
4. Adapt to high temperature (-80+300) and work in harsh environments, and can work under shock and vibration conditionsMove.
5. Simple structure, light weight, small size, convenient assembly and disassembly.It can be assembled and disassembled without moving the machine (refer to the type with intermediate shaft), and no lubrication is required.
6. It can accurately transmit the speed without slip, and can be used for mechanical transmission. JMI diaphragm couplings are widely used in metallurgy, mining, petroleum, chemical, electric power, shipbuilding, lifting and transportation, textiles, light industry, agricultural machinery, printing machinery and water pumps, fans, machine tools and other industries to transmit power in mechanical equipment.
JMIJ type intermediate shaft diaphragm coupling 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 (helicopters), naval high-speed power transmission systems, after being dynamically balanced, applied to high-speed transmission shafts Department has become more common.Compared with gear couplings, there is no relative sliding, no lubrication, sealing, noise, basically no maintenance, more convenient to manufacture, can partially replace gear couplings, diaphragm couplingsDeveloped industryThe application has been very common. In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.
The JMIJ type diaphragm coupling with intermediate shaft is deformed to compensate for the relative displacement of the connected two shafts. It is a flexible coupling with metal elastic elements. It does not require lubrication, has a compact structure, has a long service life, and has no rotation gap. , It is not affected by temperature and oil pollution, and has the characteristics of acid and alkali resistance.
