A double-material spring vibration isolation buffer

Abstract

A double-material spring vibration isolation buffer belongs to the technical field of vibration isolation buffers. The invention solves the problems that the piston stroke of the existing molecular spring vibration isolation buffer is relatively short, the hydrophobic particles used therein are prone to friction with the piston, and the bearing capacity is inconvenient to adjust. The main piston and the secondary piston are slidably arranged on the inner and outer sides of the second guide cylinder. The pre-tension spring is sleeved on the secondary piston and the bottom end is set against the top of the pre-tension block. The main piston slides through the ring-shaped end cover and the ring plate is located under the ring-shaped end cover. The cylinder body forms a closed cavity through the ring-shaped end cover, the main piston and the second guide cylinder. The inside of the cylinder is paved with hydrophobic porous The material layer and the water medium accommodated in the cavity constitute a molecular spring. Water and hydrophobic porous material layers are sealed in hydraulic containers to obtain molecular springs, and water molecules are used to enter and exit nano-scale hydrophobic pores under high pressure to complete energy conversion and loss, and realize vibration isolation and buffer protection for equipment.

Description

technical field [0001] The invention relates to a double-material spring vibration isolation buffer, which belongs to the technical field of vibration isolation buffers. Background technique [0002] With the development of the field of machinery manufacturing, modern engineering technology no longer pursues high power and high speed alone, and the vibration and shock of equipment has 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. Passive vibration isolation equipment has been widely used because of its simple principle, low cost, and stable operation. However, traditional passive vibration isolation equipment does not perform satisfactorily in the field of heavy load and low frequency. 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 molecule...
