A new round of diaphragm coupling selection and design

Let’s first learn about the structural principle of the diaphragm coupling. It is a product that relies on the elastic 

deformation of the diaphragm to compensate for the relative displacement of the two connected shafts. It is a high-

performance flexible coupling with strong metal components. No lubricating oil is required during use, the structure 

is compact, the strength is high, the service life is long, there is no rotation gap, and it is not affected by temperature 

and oil pollution. It has the characteristics of acid resistance, alkali resistance and corrosion resistance, and is suitable 

for high temperature, high speed, and corrosive medium working conditions. The shaft system transmission is also 

used as usual.


It is mainly used by customers for shaft system transmission of various mechanical devices, such as water pumps 

(especially high-power and chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing 

machinery, textile machinery, chemical machinery, mining machinery, and metallurgy. High-speed power transmission 

systems of machinery, aviation (helicopters), ships, steam turbine units, and occasions requiring high-speed transmission 

need to be installed and used after dynamic balancing.
