A Gas Linear Damping Constant Stiffness Vibration Isolator

Abstract

The invention discloses a linear damping type constant-rigidity vibration isolator for gas and belongs to the field of isolators. The isolator includes a housing, an end cover A, an end cover B and acombined piston module, wherein the end covers A and B are installed at the two ends of the housing, and the combined piston module is installed in the housing; the combined piston module includes a cylinder body, a piston capable of sliding freely in the cylinder body, a piston rod installed on the piston and a baffle installed on the piston rod; one end of the piston rod penetrates through a liner bearing on the end cover B and extends to the outer side of the end cover B. The vibration isolator also includes metal spiral springs which are installed at the two ends of the piston rod and connected with the baffle and the end cover B respectively; the cylinder body is a thin-wall drum with two porous ends, one end of the cylinder body is fixedly installed on the end cover A, and the otherend of the cylinder body is installed in the housing; a chamber, between the piston and the end cover A, of the interior of the cylinder body is filled with compressible gas. The linear damping type constant-rigidity vibration isolator for gas can increase damping.

Description

technical field [0001] The invention mainly relates to the field of vibration isolators, in particular to a gas linear damping type constant stiffness vibration isolator. Background technique [0002] Various requirements for precision electronic instruments As the precision requirements of instruments are getting higher and higher, although the vibration isolators widely used in the prior art have both stiffness and damping characteristics, the stiffness and damping are usually provided by general-purpose structural elements , that is, it is difficult for them to meet the requirements of constant stiffness and increased damping of electronic equipment during transportation. Therefore, it is of great significance to involve a vibration isolator with constant stiffness and linear transformation of damping. Contents of the invention [0003] The technical problem to be solved by the present invention is: Aiming at the technical problems existing in the prior art, the presen...
