Novel air bag vibration isolator

Abstract

The invention relates to a vibration isolator, in particular to a novel air bag vibration isolator. Comprising an outer bag body, cover plates fixed to the two ends of the outer bag body and clamping parts used for connecting the outer bag body and the cover plates, the outer bag body comprises a main bag body and a connecting bag body arranged on the outer side of the end of the main bag body, and a first extrusion ring is arranged between the corresponding connecting bag body and the cover plate; the inner wall of the cover plate is provided with an abutting ring, a filling ring is arranged between the abutting ring and the corresponding first extrusion ring, the side, close to the corresponding cover plate, of the first extrusion ring is provided with a first sliding face, and a sealing belt ring is further arranged between the filling ring and the main bag body. The air leakage problem of the first gap can be effectively solved through the sealing belt ring, the air leakage problem of the second gap can be effectively solved through arrangement of the first sliding face and extrusion of the filling ring and the abutting ring, the vulcanization process between the first extrusion ring and the connecting bag body can be reduced, and the preparation technology is simplified.

Description

technical field [0001] The invention relates to a vibration isolator, in particular to a novel airbag vibration isolator. Background technique [0002] Mechanical noise is one of the main noise sources of large mechanical equipment. Adopting the overall vibration isolation technology for hundreds of tons of large and super-large equipment is the most effective technical means to control mechanical noise at present. In the prior art, a vibration isolator generally includes an outer bladder and upper and lower cover plates located at both ends thereof, wherein the two ends of the outer bladder and the upper and lower cover plates are connected by flanges and fixing bolts, and the outer bladder generally includes forming The main bag of the chamber and the connecting bag used for connection, the connecting bag generally wraps the middle flange, and the upper and lower ends of the connecting bag are respectively provided with internal flanges and external flanges. The flange a...

Problems solved by technology

[0003] In actual use, because the inner flange is made of metal, which is different from the material of the connecting capsule, after vulcanization, because the chamber is filled with high-pressure gas, during long-term use, the inner flange and the connecting capsule will It will gradually peel off in a high-pressure environment, resulting in a decrease in the airtightness of the structure

Due to the limitations of the internal structure of the vibration isolator, the seal between the inner flange and the cover plate is generally only sealed by a single method of sealing strips, and the sealing effect is not very ideal.
