Common application fields of diaphragm couplings are widely used in 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 (helicopter), high-speed warships. Power transmission system, steam turbine, piston power mechanical transmission system, tracked vehicle, and high-speed and high-power mechanical transmission system of generator set have been widely used in high-speed transmission shafting after dynamic balancing.

What are the operating characteristics of diaphragm coupling?

1. The diaphragm coupling exerts predictable low additional negative force and bending moment on the connecting device compared with the same kind of flexible transmission elements.

2. Diaphragm coupling has high power-mass ratio, which is especially suitable for connecting high-power power power devices.

3. The non-linear change of the stiffness between the diaphragm couplings effectively restricts the drift of the magnetic center of the motor.

4. Non-lubrication and maintenance of diaphragm couplings can fundamentally eliminate the vibration of gear couplings caused by tooth surface wear and avoid a series of troubles such as new imbalance caused by oil accumulation of gear couplings.

5. The diaphragm coupling can be assembled and disassembled without disturbing the master-slave device. The replacement of the coupling can be completed within 2 hours to improve the utilization rate of the equipment.

6. Diaphragm couplings can operate in harsh environment and under 300 degrees Celsius. They can operate in corrosive environments such as acid, alkali and salt spray.

7. Diaphragm coupling has strong ability to withstand misalignment. It has certain ability to reduce vibration and noise. It can meet the misalignment requirements of most power transmission devices.

8. The diaphragm coupling has zero clearance and constant low unbalance. The noise-free coupling parts are assembled without clearance, no running noise, and the initial dynamic balance accuracy remains unchanged.
