Gas spring type vibration removal device

Abstract

An isolator (2) is provided with a vertical air spring (S1) which vertically supports a mounting base (3), and horizontal air springs (S2, S2, ...) which horizontally support the mounting base (3). The gas springs (S1, S2, S2, ...) respectively have an inner casing (20), an outer casing (200), a piston (30, 300), and a diaphragm (40, 400) which defines an air chamber (23, 230). The air springs (S2, S2, ...) are removably mounted to the outer peripheral surface of the inner casing (20) of the air spring (S1).

Description

technical field [0001] The present disclosure relates to a gas spring type vibration isolation device. Background technique [0002] For example, Patent Document 1 discloses such a gas spring type vibration isolator. In the gas spring type vibration isolator, an up-down direction gas spring that supports the supported body in the vertical direction and a horizontal direction gas spring that supports the supported body in the horizontal direction The gas spring is set on a fixed base made of steel. [0003] In this vibration isolator, the gas springs in the horizontal direction are disposed opposite to each other on both sides in the horizontal direction with the fixed base interposed therebetween, and the central axes substantially coincide with each other. Furthermore, the vertical direction gas spring and the horizontal direction gas spring each include a concave portion, a piston, and a diaphragm. Wherein, the concave part of the fixed base has an opening facing outward...

Problems solved by technology

[0007] However, if Image 6 As shown, the gas spring type vibration isolator disclosed in Patent Document 1 has the following problem: Since the concave portion of the gas spring in the horizontal direction is provided on the side wall member of the fixed base, the gas chamber of the gas spring in the vertical direction cannot be enlarged. volume
