Rubber air spring is used for efficient vibration isolation of mechanical equipment and assemblies. Prevent vibration caused by shock and oscillation. The bell-shaped parts are manufactured from high-quality synthetic rubber, and their structure allows efficient vibration isolation without excessive horizontal deformation. Rubber air spring RASSM due to its special material, so will not be due to overload or sudden drop in pressure and rupture. Components can increase attenuation and reduce vertical damping. Rubber air bomb RASSM base plate is equipped with anti-skid pad, so it is not necessary to fix the machine to the ground with foot bolts.
Advantages and characteristics of rubber air spring;
1. Variability selection of spring height, bearing capacity and spring stiffness:
When in use, the spring height, bearing capacity and spring stiffness can be selected independently of each other and in a wide range, and extremely flexible spring characteristics can be obtained.
2. Spring height:
The height control valve can be used to properly control the height of the air spring according to the use requirements, and keep a certain height under the condition of changing the sprung load.
3. Carrying capacity:
For rubber air springs of the same size, different bearing capacity can be obtained by changing the internal pressure, and the bearing capacity is roughly proportional to the internal pressure. This achieves the same kind of rubber air spring can adapt to a variety of loading requirements.
4. Spring stiffness:
When designing the stiffness of rubber air spring, it can be selected by changing the internal pressure of the spring, and the stiffness is roughly proportional to the internal pressure. Therefore, the stiffness can be selected as low as needed. For a rubber air spring with a given size, the stiffness is variable, and it varies with the change of load, so the natural frequency is almost constant under any load, so it can make the supported system have almost constant cliff.
5. The inherent vibration frequency is low
The rubber air spring is connected with the additional air chamber, which can reduce the natural vibration frequency of the rubber air spring device to 0.5---3E. Under the action of any load, the rubber air spring can keep a low and almost equal vibration frequency.
6. It can isolate high-frequency vibration and has good noise isolation effect
Rubber-air bullet is composed of air and rubber, and its internal friction is small, so its ability to isolate high-frequency vibration will not be affected by the natural vibration of the bullet basket itself. In addition, the rubber air spring has no contact between metals, so it has a good effect of preventing noise by using it.
7. The damping effect of air can be utilized
A throttle hole is added between the rubber air spring and the additional air chamber. When the spring load vibrates, the energy loss occurs when the air flows through the throttle hole, thus playing a role in attenuating vibration.
8. Longer service life
The fatigue resistance of rubber air spring is many times better than that of metal spring. Fatigue test is carried out for springs in vehicle air spring suspension system. The leaf spring was broken after only hundreds of thousands of vibrations, while the rubber air spring was not broken after 5 million vibrations under the condition of amplitude 40mm and frequency 2.7 Hz (160 times/min).
9. Ontology structure
The body structure of rubber air spring is soft. Therefore, it has the comprehensive vibration isolation function in axial, transverse and rotational directions.
10. Fabrication and installation
The rubber air spring is relatively low in cost and convenient to install and replace. Simple maintenance, no need for frequent maintenance and no need for refueling.
