The rubber isolator is made of rubber. The rubber isolator can be used in both compression and shear states. The biggest advantage of rubber isolator is that it has enough internal damping, which is suitable for small static displacement but large dynamic displacement, and can be made into various shapes to meet the requirements of space. The downside is that it will age and creep. Mainly used to isolate high frequency vibration.
Rubber shock isolator is made of metal and rubber, which can prevent metal corrosion. Its natural frequency underrated load is the lowest among various types of rubber shock isolators in China
. It is suitable for the basic vibration and noise reduction of power machinery such as fan, pump, air compressor, refrigerator and so on, whose rotating speed is more than 600 RPM. When the load is larger than the rated load, the natural frequency of the rubber isolator remains unchanged. The damping ratio is large, and the ability to suppress the resonance peak is strong. It can also be fixed and installed with foundation bolts, which can be used safely and reliably. The load range is 30 kg to 850 kg. It is suitable for working in a temperature range of -15~+60 degrees.
Rubber isolator is the simplest vibration isolation component made of rubber material, and it is also a common vibration isolation device in engineering. It can be divided into compression type, shear type and compression shear type. The rubber isolator is generally composed of a restraint surface and a free surface. The restraint surface is usually connected with metal. The free surface refers to the side that deforms when it is loaded vertically on the restraint surface. The vibration isolation parameters of the rubber isolator are not only related to the composition of the rubber material used, but also related to the factors such as the shape of the structure, the mode of force and so on.
The elastic coefficient of the rubber isolator can be changed in a wide range by changing the rubber composition and structure to meet the needs of design and use. The rubber isolator is not suitable for the low natural frequencies, and the static compression capacity cannot be too large. Therefore, it is not suitable for systems with low interference frequency and equipment with large weight. It is more suitable for vibration isolation of small and medium-sized equipment. The commonly used frequency range is 5 ~ 15Hz. The performance of rubber isolator
is greatly affected by temperature, and its performance is not good at high temperature; the elastic coefficient will change when it is used at low temperature.
