Rubber buffering and vibration isolating elastomer structure

Abstract

The invention relates to a rubber buffering and vibration isolating elastomer structure which comprises an upper metal part, a rubber part and a lower metal part. An internal cavity structure is adopted by the rubber body of the invention to increase the buffering stroke of the rubber body, and the buffering deformation of the rubber body can reach 100%; and if the space along the axial direction of the elastomer structure is large enough, the buffering deformation can reach about 150%. The design of the cavity structure greatly increases the buffering deformation stroke of the rubber part by 2-4 times of the traditional rubber isolator, thereby greatly improving the buffering effect. The structure of the invention adopts the design of a gas channel; on the one hand, by the design of the gas channel, when the elastomer bears the impact load, because the action time of the load is short, the gas in the cavity is quickly discharged outwards through the gas channel, and the friction action of the gas and the channel increases the damping of the elastomer structure, thereby increasing the buffering effect of the elastomer structure; and on the other hand, by the design of the gas channel, the gas in the cavity can be smoothly discharged under the action of the load to avoid the uneven deformation of the rubber part caused by sealing of the cavity, thereby ensuring the rigidity stability of the elastomer structure in the deformation process.

Description

technical field [0001] The invention relates to a buffer and vibration isolation structure, in particular to a metal and rubber composite buffer and vibration isolation structure, which belongs to the technical field of rubber vibration isolator structures and is mainly used for buffer and vibration isolation treatment of equipment or instruments. Background technique [0002] Rubber vibration isolators are widely used because of their simple manufacturing process, convenient and effective use, and a certain buffering effect. It should be pointed out that, theoretically, vibration isolation and buffering are a pair of contradictions. An ideal vibration isolator has no buffering effect, and an ideal buffer has no vibration isolation effect. Although the traditional rubber vibration isolator has the function of vibration isolation, it is often powerless to deal with the impact problem, especially the impact problem under the condition of heavy load. Vibrating equipment or ins...

Problems solved by technology

Although the traditional rubber vibration isolator has the function of vibration isolation, it is often powerless to deal with the impact problem, especially the impact problem under the condition of heavy load. Vibrating equipment or instruments impact the mechanical environment

The reason is mainly that the traditional rubber vibration isolator has a limited cushioning stroke under impact load, and the rubber vibration isolator has a nonlinear rigidity caused by the nonlinearity of the rubber material properties within the limited buffering stroke, resulting in its cushioning effect. not obvious
