Description

Technical Field

[0001] The utility model discloses a vibration isolator with a metal rubber pad, belonging to the technical field of vibration isolators, and particularly relates to a combined metal rubber pad vibration isolator. Background Art

[0002] Vibration isolators are usually used in engineering and technical fields to reduce the vibration influence or transmission on mechanical equipment or structures during operation. They can help protect equipment from external vibration interference and also reduce the impact of vibration generated by the equipment itself on the surrounding environment.

[0003] The principle of a vibration isolator is to convert vibration energy into other forms of energy (such as heat energy) through a certain material or structure, such as a spring, damping rubber or damping pad, or to reduce the vibration transmission by means of reverse vibration. This can prevent the vibration from spreading in the structure, thereby protecting the surrounding equipment or buildings from damage or interference.

[0004] Common applications include installing vibration isolation devices in building structures to reduce the impact of earthquakes or wind vibrations on buildings, or using them in precision instruments and scientific experimental equipment to ensure the stability and accuracy of their operation are not affected by vibration interference.

[0005] Most of the vibration isolators in the prior art are made of metal or rubber. Metal vibration isolators have high strength, but small plasticity, large generated pressure, and metal vibration isolators are prone to oxidation and rust inside the body, thus affecting the use of the vibration isolator. Rubber vibration isolators have low strength and low lifespan, but large plasticity and small generated pressure. Therefore, a combined metal rubber pad vibration isolator is needed to solve the above problems. Summary of the Utility Model
