Two-stage vibration isolation buffer

Abstract

The invention discloses a two-stage vibration isolation buffer, and belongs to the technical field of vibration isolation buffers. The problems that an existing vibration isolation buffer is low in energy conversion rate and longitudinal impact resistance are solved. The lower portion of a connecting end cover is arranged between two cylinder bodies and fixedly connected with the second-stage cylinder body, the upper portion of the connecting end cover is inserted into the first-stage cylinder body and fixedly connected with the inner wall of the first-stage cylinder body, a piston is arrangedin the first-stage cylinder body in an up-down sliding mode, and the upper portion of the piston penetrates through the first-stage cylinder body and is fixedly connected with a guide cylinder; and acomposite membrane is fixedly clamped between the connecting end cover and the second-stage cylinder body and attached to the inner wall of the connecting end cover, the upper surface of the middle of the composite membrane is attached to the bottom of the piston, and the composite membrane, the connecting end cover and the first-stage cylinder body form a closed first-stage cavity. Two closed cavities which are isolated from each other are formed, energy consumption and energy storage are achieved at the same time, and on the basis of a molecular spring, the problem that low inherent frequency and small static deformation cannot be achieved at the same time under heavy loads is solved in combination with the working principle of the energy consumption type vibration isolation buffer.

Description

technical field [0001] The invention relates to a double-stage vibration-isolation buffer, which belongs to the technical field of vibration-isolation buffers. Background technique [0002] In the field of modern machinery manufacturing, heavy equipment no longer pursues high power and high speed alone, and its vibration and shock have also attracted widespread attention. Mechanical vibration will not only generate noise, but also cause fatigue damage to components and reduce the service life of equipment. At present, passive vibration isolation equipment has been widely used because of its simple structure, low cost and stable operation. However, the performance of traditional passive vibration isolation equipment in the field of heavy load and low frequency is not satisfactory. [0003] At present, a new type of vibration isolation buffer with molecular springs as the core is gradually being developed and applied. This technology uses water molecules to enter and exit nan...
