A double-stage vibration isolation buffer

Abstract

The invention discloses a two-stage vibration isolation buffer, which belongs to the technical field of vibration isolation buffers. The invention solves the problems of low energy conversion rate and longitudinal impact resistance of the existing vibration isolation buffer. The lower part of the connecting end cover is set between the two cylinders and fixedly connected with the secondary cylinder body, the upper part of the connecting end cover is inserted into the primary cylinder body and fixedly connected with the inner wall of the primary cylinder body, and the piston slides up and down and is set at The first-stage cylinder and the upper part of the piston pass through the first-stage cylinder and are fixedly connected to the guide cylinder. The composite diaphragm is fixedly clamped between the connecting end cover and the second-stage cylinder and is attached to the inner wall of the connecting end cover. The composite membrane The upper surface of the middle part of the sheet is attached to the bottom of the piston, and the composite diaphragm, the connecting end cover and the first-stage cylinder form a closed first-stage chamber. This application has two sealed chambers isolated from each other, which realize energy consumption and energy storage at the same time. On the basis of molecular springs, combined with the working principle of energy consumption type vibration isolation buffer, it overcomes the low natural frequency and small vibration under heavy load. Static deformation can not have both problems.

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...
