MOREJMI basic diaphragm coupling with counterbore
Diaphragm couplingAlso called elastic laminated coupling, or laminated flexible coupling, one of the new couplings developed in recent years. This product is a new product successfully developed by Changrui Transmission through continuous absorption of technology. The metal film The disc coupling can compensate various misalignment errors of the connected two shaft systems (radial error, axial error, angular displacement error, error caused by temperature rise), JMI type basic diaphragm coupling with counterbore Shafts mainly 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 reduction, no wear, and no maintenance. It is today's replacement of gear couplings and general couplings. The ideal product of our factory is (JB/T 9147-1999).
Main features of JMI diaphragm coupling
1. The ability to compensate for the misalignment of the two axes is strong. Compared with the gear coupling, the angular displacement can be doubled, the reaction force is small during the radial displacement, the flexibility is large, and the larger axial, radial and angle are allowed. To displacement.
2. It has obvious shock absorption, no noise and no wear.
3. High transmission efficiency.Especially suitable for medium, high speed and high power transmission.
4. It is suitable for working in high temperature (-80+300) and harsh environment, and can move under shock and vibration conditions.
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.
