Introduction
Double diaphragm coupling relies on the elastic deformation of the
diaphragm to compensate the relative displacement of the two
shafts. It is a high-performance flexible coupling for metal
elastic components. It is not lubricated, has a compact structure,
high strength and long service life. It has no rotating gap, is not
affected by temperature and oil pollution, and has the
characteristics of acid resistance, alkali resistance and corrosion
resistance. It is suitable for shaft drive of high temperature,
high speed and corrosive medium working conditions, and is widely
used in shafting of various mechanical devices. Transmissions, such
as 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 power of
ships Transmission systems, steam turbine piston-type power
mechanical transmission systems, crawler-type vehicles, and
high-speed, high-power mechanical transmission systems for
generator sets have been widely used in high-speed transmission
shafting after dynamic balancing. Compared with the toothed
coupling, the diaphragm coupling has no relative sliding, no
lubrication, no sealing, no noise, no maintenance, and is
convenient to manufacture. It can partially replace the gear
coupling.
Advantages of diaphragm couplings
1. It has obvious shock absorption effect, no noise and no wear.
2. Adapt to work in high temperature and harsh environment
3. High transmission efficiency, up to 99.86%.
4, simple structure, light weight, small size, convenient assembly
and disassembly. It can be assembled and disassembled without
moving the machine (refers to the type with intermediate shaft),
without lubrication.
5, can accurately transfer speed, no slippage in operation, can be
used for transmission of precision machinery
Application of diaphragm coupling
Suitable for medium, high speed and high torque shaft drive. And
the shafting transmission of various mechanical devices with little
load change is very versatile.
