Metal compounded rubber vibration isolator

Abstract

The invention discloses a metal compounded rubber vibration isolator; and a traditional vibration isolator adopts a pure rubber, so that the service life is short. The metal compounded rubber vibration isolator comprises a shell, a rubber spring and a positioning sleeve. Multiple flanges are symmetrically arranged at the edge of the shell; and a frustum body with an L-shaped section is arranged in the middle. Multiple steps are arranged on the outer wall of the positioning sleeve; the positioning sleeve is positioned in the shell; and the rubber spring is arranged between the positioning sleeve and the inner wall of the shell. The rubber spring between the shell and the positioning sleeve relieves the vibration generated by the impact force of an external component on the rubber spring so as to realize the purpose of vibration isolation. Through the shape design of the L-shaped frustum body of the shell and the multiple steps on the outer wall of the positioning sleeve, the phenomenon of axial shrinkage or radial shrinkage of a runner body of a traditional vibration isolator is prominently improved, and the service life of the packer is prolonged. As the invention discloses the metal compounded rubber vibration isolator, the metal compounded rubber vibration isolator cannot be used under the effect of heavy load for a long time, and has the characteristic of high wear resistance.

Description

technical field [0001] The invention relates to a vibration isolator, in particular to a vibration isolator between two components in heavy machinery, and belongs to the technical field of vibration reduction. Background technique [0002] It is known that large-scale machinery has high requirements on the damping capacity of the support damper, and generally adopts flexible connection, such as using pure rubber as the support damper, which can control the transmission of vibration and alleviate the impact force caused by vibration between components. However, the strength of the support shock absorber of this type of structure is low, and due to long-term use in a heavy-load environment, it is easy to produce "axial retraction" or "radial retraction", which greatly shortens the service life of the vibration isolator. Therefore, the design of a metal shell shock absorber not only ensures that the isolator has sufficient elasticity, but also makes the isolator have high wear ...

However, the strength of the support shock absorber of this type of structure is low, and due to long-term use in a heavy-load environment, it is easy to produce "axial retraction" or "radial retraction", which greatly shortens the service life of the vibration isolator. Therefore, designing a metal shell shock absorber not only ensures the sufficient elasticity of the vibration isolator, but also makes the vibration isolator have high wear resistance and high strength characteristics, which plays an important role in prolonging the service life of the vibration isolator
