Roll-free variable-stiffness vibration damping bearing

Abstract

The invention discloses a roll-free variable-stiffness vibration damping bearing. The roll-free variable-stiffness vibration damping bearing comprises a lower basin, a rubber plate body, a liner plate body and a backing plate body, wherein the rubber plate body is arranged in at bottom of the inner side of the lower basin; the lower surface of the liner plate body is in contact connection with the upper surface of the rubber plate body; the upper surface of the liner plate body is in contact connection with the lower surface of the backing plate body. Grooves are respectively formed in the upper surface or / and the lower surface of the rubber plate body of the roll-free variable-stiffness vibration damping bearing disclosed by the invention, so that the grooves can provide space for the compression deformation of the rubber plate body; the area proportion of the different grooves is adjusted, the rubber plate body with different elastic properties can be obtained; the rubber plate body is relatively closed in the inner space by the lower basin of the roll-free variable-stiffness vibration damping bearing; the conditions that the rubber plate body is exposed in air and directly radiated the ultraviolet rays, and is directly eroded by poor weather conditions are avoided; the service life of the vibration damping bearing disclosed by the invention is prolonged.

Description

technical field [0001] The invention relates to an elastic support structure, in particular to a vibration-damping support with variable stiffness without side tilt. Background technique [0002] At present, with the rapid development of urban rail transit and more and more construction mileage, the backing plate supporting the track must have certain elastic properties to reduce the impact, vibration and noise generated when the train is running, while the track backing plate in the prior art , either the elastic performance is poor, the effect of vibration and noise reduction is not ideal, or the price is expensive, and the cost is too high, so the rail backing plate urgently needs to further improve its elastic performance and reduce the cost of the vibration-damping support. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a non-rolling variable stiffness vibration damping support, which has the advantages of ...
