Anti-vibration rubber bushing

Abstract

The invention provides an anti-vibration rubber bushing. Even though the anti-vibration rubber bushing is used for a large-diameter rubber flexible joint, the rubber bushing can bear relatively high load counter-force, and can obtain moderate flexure to exert anti-vibration performance. The anti-vibration rubber bushing (1) is provided with a first flange component (2) which is provided with a bolt through hole (6), a second flange component (3) which is provided with a bolt through hole (7) concentric to the bolt through hole of the first flange component, and an elastic rubber member (5) clamped between the first flange component and the second flange component. The elastic rubber member (5) is integrally configured with a spring member (8) which has better load-resisting property than the elastic rubber member, the spring member (8) being arranged in an embedded manner.

Description

technical field [0001] The present invention relates to an anti-vibration rubber bush, and more specifically, relates to a bolt mounted on a control unit for controlling the elongation of a rubber flexible joint to obtain load resistance (reaction force), moderate deflection, and anti-vibration performance. Excellent rubber bushing. Background technique [0002] Conventional rubber bushes of this type consist of urethane rubber and two steel plates (without welding), and are used in different sizes depending on the caliber of the rubber flexible joint and the type of reaction force. The thickness of the urethane rubber is about 10mm, and the hardness is 90Hs, which is harder than general synthetic rubber, and it is designed to withstand a large load. [0003] However, a control unit that controls the elongation of a rubber flexible joint generally requires a rubber bush as a vibration-proof member. Conventional rubber bushings support the reaction force of the joint only w...

AI Technical Summary

Problems solved by technology

Conventional rubber bushings support the reaction force of the joint only with urethane rubber as described above, but as the diameter of the joint increases, the reaction force increases, and the rubber cannot support it alone, and the rubber is completely crushed.

In addition, the installation space is also limited, and there is a limit to the load resistance

Therefore, there is a problem that even if it is used in a rubber flexible joint with a large diameter, it cannot sufficiently withstand a large load reaction force, and the deflection becomes large, so that the anti-vibration performance cannot be expected.

[0006] However, this anti-vibration rubber bush has a structure in which only the rubber elastic body is sandwiched between the inner cylinder fitting and the outer cylinder fitting as described above, so there is no major change from the conventional rubber bush described above, and there are the same The problem
