Key Features of JMI Type Diaphragm Coupling
1. the ability to compensate for the two axes is not right, compared with the tooth coupling angular displacement can be doubled, the radial displacement of small force, flexible, allowing a certain axial, radial and angular displacement.
2. has a significant damping effect, no noise, no wear.
3.transmission efficiency, up to 99.86%. Especially for high-speed high-power transmission.
4. to adapt to high temperature (-80 +300) and harsh environment work, and in the impact, vibration conditions, safe movement.
5. simple structure, light weight, small size, easy assembly and disassembly. Do not have to move the machine can be assembled with (with intermediate shaft type), without lubrication.
6. can accurately transmit speed, running without slip, can be used for precision machinery transmission. JMI-type diaphragm coupling is widely used in metallurgical, mining, petroleum, chemical, power, ship, lifting transport, textile, light industry, agricultural machinery, printing machinery and pumps, fans, machine tools and other industries in the transmission of power equipment.
Its products apply widely in transportataion, metallurgy, chemical industry, mine, building construction, hoist and other industries and equipments, and supply for various major industries year by year.
