Damping device

Abstract

The invention discloses a damping device. The damping device comprises an installing portion, an upper connecting rod, a connecting portion, a lower connecting rod and a supporting portion, wherein a first through hole is formed in the installing portion, the two ends of the upper connecting rod are respectively provided with an upper protruding column, a second through hole and a third through hole are formed in the connecting portion, the two ends of the lower connecting rod are respectively provided with a lower protruding column, a fourth through hole is formed in the supporting portion, the two upper protruding columns extend into the first through hole and the second through hole respectively, the position between the first through hole and the upper protruding column extending into the first through hole is filled with a first vibration absorption column, the position between the second through hole and the upper protruding column extending into the second through hole is filled with a second vibration absorption column, the two lower protruding columns extend into the third through hole and the fourth through hole respectively, the position between the third through hole and the lower protruding column extending into the third through hole is filled with a third vibration absorption column, and the position between the fourth through hole and the lower protruding column extending into the fourth through hole is filled with a fourth vibration absorption column. The damping device can be widely applied to various vibrating screens, linear vibration feeding devices and large-sized vibrating devices, is wide in vibration reduction range, cannot be influenced by the weight of materials, is free of noise, and can prevent connection positions from loosening.

Description

Technical field [0001] The invention relates to a vibration damping device, in particular to a vibration damping device used for various types of vibrating screens, linear vibration feeding devices and large-scale vibration equipment. Background technique [0002] At present, all kinds of vibrating screens, linear vibrating feeding devices and large-scale vibrating equipment mainly rely on springs to dampen vibration, and the springs used mainly include metal spiral springs, rubber springs and composite springs. The metal coil spring has good vibration damping performance, but large operating noise; the rubber spring has low operating noise, but the internal resistance is large, and the vibration damping effect is not ideal; because the composite spring is a composite of all the metal coil springs with rubber, its manufacturing cost is relatively high , The adjustment of spring stiffness is also more difficult. Summary of the invention [0003] The purpose of the present inventio...
