Elastic device

Abstract

The invention relates to an elastic device which comprises an elastic body. The elastic body is formed by curling and stacking a metal wire. The cross section of the metal wire is almost shaped like a regular polygon. A strengthened layer is arranged on the outer surface of the elastic body. Compared with a spring with the turns and the length identical to those of the elastic device and a circular spring with the cross sectional area identical to that of the elastic device, in other words, compared with the spring with the elastic force equal to that of the elastic device, the gaps between the turns of a spring are larger, the compression space of the spring is larger, and the compression effect is better; through the arrangement of the strengthened layer, the fatigue strength of the spring is remarkably improved, the fatigue life of the spring is prolonged more than one time, the corrosion resistance of the spring is improved, and the cost of the high-strength spring is effectively reduced.

Description

technical field [0001] The invention relates to the field of springs, in particular to an elastic device. Background technique [0002] A spring is a mechanical part that uses elasticity to work, and is generally made of spring steel. It is used to control the movement of parts, alleviate shock or vibration, store energy, measure force, etc. It is widely used in machines and instruments. The spring is just an accumulator. It has the function of storing energy, but it cannot release the energy slowly. To realize the function of releasing energy slowly, it should be realized by "spring + large transmission ratio mechanism", which is common in mechanical watches. Springs have been used a long time ago, and ancient bows and crossbows are two types of springs in a broad sense. According to the nature of the force, the spring can be divided into tension spring, elastic device, torsion spring and bending spring, and can be divided into disc spring, ring spring, plate spring, ...

AI Technical Summary

Problems solved by technology

[0003] The elastic device is a kind of mechanical power storage structure, which is widely used in modern industry, but the existing tension springs include elastic bodies, the elastic bodies are formed by curling and superimposing metal wires, and the cross-sections of the metal wires are generally It is a circular spring with the same number of coils and length. When compressed, because the distance between the spring coils is relatively small and the compression space is small, the compression effect is poor, and the cushioning effect that can be achieved is not good; and the elasticity Fatigue fracture occurs in the device, and the anti-corrosion effect is poor
