Abstract
The utility model relates to a shock absorbing structure, which comprises a shock absorbing cylinder body having one open end and a through hole formed in the middle part of the other end, wherein the open end of the shock absorbing cylinder body is fixedly provided with a soleplate and a shock absorbing rod of which one end is in the shock absorbing cylinder body and the other end extends out from the shock absorbing cylinder body by passing through a through hole on the end part of the shock absorbing cylinder body; the end part of the shock absorbing rod in the shock absorbing cylinder body is provided with a magnetic piston and a shock absorbing magnet arranged in the shock absorbing cylinder body and positioned below the magnetic piston; the shock absorbing magnet and the magnetic piston have the same polarity and are arranged opposite to each other; a shock absorbing spring is arranged between the lower end face of the magnetic piston and the upper end face of the shock absorbing magnet, and one end of the shock absorbing spring is fixedly arranged on the upper end face of the shock absorbing magnet. The shock absorbing structure causes no mechanical abrasion because of none contact due to magnetic suspension, thereby having long service life and good shock absorption effect.
Description
Technical field
The utility model relates to a kind of shock-damping structure, is mainly used in the damping shock absorption of industrial machinery equipment vibrations, to reduce the damage of mechanized equipment vibrations to environment and adjacent facility.
Background technique
What at present, be used for that industrial vibration damper adopts is elastic element or the bellows vibration damper as damping member.Such vibration damper is the to-and-fro motion by elastic element or bellows, in the to-and-fro motion of vibration, produces a power opposite with moving direction, and this mechanical resistance hinders shock motion, plays the effect of damping.This vibration frequency is very high, makes damper element be easy to generate fatigue ruption, and vibration damper can very fast forfeiture shock-absorbing function.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides the shock-damping structure of a kind of simple in structure, good damping effect, long service life.
The technological scheme that realizes the utility model purpose is as follows:
A kind of shock-damping structure, comprise that an end opens wide, the other end middle part has the damper cylinder body of through hole, the open end of damper cylinder body is set with base plate, and one end be positioned at damper cylinder body, the through hole that the other end passes the damper cylinder body end stretches out the outer decoupling rod of damper cylinder body, the decoupling rod end that is positioned at damper cylinder body is set with the magnet piston, and be arranged on the damping magnet that is positioned at magnet piston below in the damper cylinder body, damping magnet and magnet piston are that same polarity is oppositely arranged, be provided with damping spring between described magnet piston lower surface and the damping magnet upper-end surface, an end of damping spring is fixedly installed on damping magnet upper-end surface.
Described damping spring is a plurality of, and a plurality of damping springs are distributed on the upper-end surface of damping magnet.One end of damping spring is fixedlyed connected with damping magnet upper-end surface, and the other end only when the decoupling rod load, just contacts with the lower end surface of magnet piston.
Be positioned at magnet piston upper fixed in the described damper cylinder body and be provided with the second damping magnet, the second damping magnet and magnet piston are that same polarity is oppositely arranged.
Further, for the magnet in normal performance of the function that guarantees damping and the protection damper cylinder body, described damper cylinder body, decoupling rod, base plate are NULL and are made.
Adopt such scheme, damping magnet and magnet piston are that same polarity is oppositely arranged, the second damping magnet and magnet piston are that same polarity is oppositely arranged, the principle that the utility model adopts the magnet same sex to repel each other, reach damping effect, the damping spring that is fixedly installed on damping magnet upper-end surface in addition plays cushioning effect further.The utility model can not produce mechanical wear because magnetcisuspension is contactless, thereby long service life, and good damping effect.
