Common application areas of diaphragm couplings Couplings are 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), naval high-speed power transmission systems, steam turbines, piston-type power mechanical transmission systems, crawler vehicles, and high-speed, high-power mechanical transmission systems of generator sets. After dynamic balancing, it is more common to apply to high-speed transmission shafting.

　　What are the operating characteristics of the diaphragm coupling:

　　1. The diaphragm coupling exerts a predictable low additional load on the connected device. Compared with similar flexible transmission elements, the diaphragm coupling exerts the smallest predictable force and bending moment on the connected device.

　　2. The diaphragm coupling has a high power-to-mass ratio, which is especially suitable for connecting high-power power devices.

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

　　4. The diaphragm coupling should not be lubricated, and maintenance-free can fundamentally eliminate the vibration of the gear coupling due to tooth surface wear and avoid a series of troubles such as a new imbalance of the gear coupling due to oil accumulation.

　　5. The diaphragm coupling can be assembled and disassembled without interfering with the main-slave device. The replacement of the coupling can be completed within 2 hours, which improves equipment utilization.

　　6. The diaphragm coupling can operate under harsh environmental conditions, can operate within 300 degrees Celsius, and can operate in corrosive environments such as acid, alkali, and salt spray.

　　7. The diaphragm coupling has a strong ability to withstand misalignment, and has a certain ability to reduce vibration and noise. The misalignment ability can meet the misalignment requirements of most power transmission devices in operation.

　　8. The diaphragm coupling has zero clearance and constant low unbalance. The noise-free coupling parts are assembled without gaps, no operating noise, and maintain the same initial dynamic balance accuracy.
