Description

Engineering machinery shock absorber

Technical Field

The utility model relates to a shock attenuation equipment technical field specifically is an engineering machine tool shock absorber.

Background

The rubber shock pad is generally made of natural rubber and chloroprene rubber, and for the rubber shock pad with special application, the performance of the rubber shock pad is changed by doping a small amount of other rubber in the production process, for example, nitrile rubber is doped which requires oil resistance, silicon rubber is doped which requires high and low temperature resistance, butyl rubber is doped which requires high damping, and the like. Rubber shock absorbing pads are generally made into supporting or connecting pieces and widely used in various vehicles, ships, machinery, instruments, bridges and buildings to eliminate or alleviate the adverse effects of vibration.

The rubber part of the existing rubber shock absorber is made of an integral material, has consistent performance, cannot be well adhered to a metal part and absorb vibration in any direction, and is adhered to a metal connecting part in a plane manner, so that the metal connecting part is easy to rust and can generate impact during mechanical vibration; furthermore, the rubber member itself cannot undergo viscoelastic deformation, and cannot simultaneously perform active damping and passive damping.
