Double Convoluted Air Spring And Applications

 

There is a belt in the middle of the air spring. This belt is called the air spring hoop, and the number of this hoop is one of the basic elements to distinguish the number of convolutions.

 

The double convoluted industrial air spring is a curved capsule made of rubber mesh. The two ends of the capsule need to be connected by two steel plates to form two compressed air chambers. The rubber and mesh cables themselves do not provide the bearing capacity of the load, but are completed by the compressed air filled into the capsule. The hyperbolic industrial air spring is an excellent low-frequency vibration isolator. It relies on the pressure change of the compressed air in the rubber bladder to achieve the required stiffness. At present, the hyperbolic industrial air spring is widely used in precision instruments, precision machinery and special equipment. low frequency vibration isolation.

 

Hyperbolic industrial air springs use the nonlinear restoring force of compressed air to achieve shock isolation and buffering. Since the United States first successfully used air springs as shock-absorbing elastic elements in the industry, air springs have gradually been widely used in many fields. Such as quenching tank pushers, papermaking equipment presses, pickling tank lifts, papermaking press rolls, straightening machines, cable tensioners, etc.
