Advantages and application fields of high speed diaphragm coupling

The basic structure of high performance diaphragm coupling is two special metal diaphragm of unequal thickness, two fairing and an intermediate shaft, connected by precision bolts. Torque is transmitted from the drive shaft through a rigid hub and then through a flexible diaphragm disc to the compartment. In transferring torque, the diaphragm ADAPTS to misalignment by deforming. The matching of the bushing drive connection on the driven device to accomplish torque transfer. The high speed and high performance diaphragm coupling can effectively absorb the position error of the transmission (rotation) parts, and can compensate in a pure elastic way under the condition of large axial, radial and Angle deviation between the connected shafts. It is a flexible transmission product with low additional bending moment and high performance specially developed for high-speed rotating machinery. Especially suitable for high speed and low bending moment units. Such as: steam turbine, gas turbine and so on.

The diaphragm coupling has the following outstanding advantages:

1, the membrane plate coupling structure is simple, in a thin metal sheet to achieve high strength, high stiffness and high barrier complete unity;

2, diaphragm coupling high strength, low moment of inertia, misalignment compensation ability of the unit, small deformation additional bending moment, can maximize the peak compensation between the radial displacement, axial displacement and angular displacement;

3, membrane disc coupling small volume, light weight, high critical speed, long fatigue life, high reliability, strong impact interference ability on the unit;

4, membrane plate coupling zero clearance transmission of high torque, effectively reduce the shaft end of the bending load, axial reaction is minimal;

5, diaphragm coupling balance precision is high, complete dynamic balance reproduction;

6, the film disc coupling corrosion resistance is good, can work continuously in the wet, heat and salt fog and other harsh working conditions;

7, membrane plate coupling maintenance free design, no lubrication or maintenance, can work continuously in a variety of bad working conditions;

8. Diaphragm coupling conforms to API671 standard.

Coupling is mainly used in oil refining and petrochemical compressor units, gas and steam turbine generator sets and special pumps and other high-speed equipment in different industries. TARR series should be preferred for general high-speed units, which are easy to be disassembled and repaired. TARM series is recommended for units requiring higher additional bending moment at shaft end, which can reach peak bending moment at small shaft end and has good dynamic characteristics. TARS series should be preferred for units with small shaft spacing, which can reach the peak of small design shaft spacing. TAHP series is recommended for honing units with higher requirements on axial displacement, which can reach the peak of large axial displacement compensation.

My company's products only for general industrial process application requirements, for some special, professional applications, such as all kinds of test rig, the compensation ability of overspeed devices and need more special equipment, can not sure where to select the appropriate model, in this case we can according to the actual requirements for special design, to meet customer special equipment professional requirements.
