In the actual working process of the diaphragm coupling, a major feature is its nature, so when they are working, especially during the entire rotation, there is no gap at all.
Diaphragm couplings were used in developed industrial applications in the 20s and 60s.After the reform and opening up, with the introduction of large-scale complete sets of industrial equipment, diaphragm couplings have gradually become known to Chinese people.
Pump couplings are common couplings. There are three types: claw-type elastic coupling, elastic pin coupling and diaphragm coupling.
The selection of the diaphragm coupling should be based on the machine type provided by the complete set or the host manufacturer and the shaft power under normal conditions, and should not be over-coded.
The elastic coupling relies on the elastic deformation of the elastic element to compensate the relative displacement of the two axes, and can also buffer and reduce vibration to avoid resonance.
The high-elastic coupling is formed by clamping a metal connecting piece and an elastic element under the pretension of a bolt group, and the elastic element is formed by vulcanizing and tightly combining rubber and a cord.
The serpentine spring coupling tooth type is curvilinear: when the load is small, the straight part of the serpentine spring is basically parallel to the connected axis.
Diaphragm couplings are used in a variety of different host products, and the surrounding working environment is more complicated, such as temperature, humidity, water, steam, sand, alkali, salt water, radiation and other conditions.
