Spring device with continuously adjustable spring characteristics

Abstract

The invention relates to a spring device with continuously adjustable spring characteristics, which is characterized in that a spiral spring is connected in parallel with a second adjusting device and then is connected in series with a first adjusting device, and the angle of a first piston adjusting plate in the first adjusting device can be adjusted through a controller, so that the elastic coefficient of the whole spring device is changed; the continuously adjustable elastic coefficient of the spring device can be obtained by continuously adjusting the angle of the first piston adjusting plate; in addition, the elastic coefficient of the first adjusting device can be additionally changed by adjusting the gas pressure in the first air cylinder so as to adjust the elastic coefficient of the spring device, and additionally, the elastic coefficient of the second adjusting device can be changed by adjusting other pressure in the second adjusting device. Therefore, the elastic coefficient of the whole spring device can be continuously adjusted in real time, the large adjusting range and space are achieved, and the complex and changeable vibration reduction requirements can be met very timely.

Description

technical field [0001] The invention relates to the field of vibration damping, in particular to a spring, in particular to a spring device with continuously adjustable spring characteristics. Background technique [0002] In the machinery industry or electromechanical industry, a large number of equipments need to use vibration damping devices to buffer and absorb the vibration and shock generated in the equipment, to ensure that the equipment is not affected by vibration and shock, or to isolate the equipment itself. Effects of vibration and shock on the outside world. [0003] The coil spring is the most commonly used vibration damping device. The coil spring is usually made of wire made of spring steel. The diameter or cross-sectional area of ​​the wire, the outer diameter of the spring and the material properties of the spring steel make the coil spring have have predetermined spring rate characteristics. Among them, the spring stiffness, also known as spring constant...

AI Technical Summary

Problems solved by technology

[0004] During the use of the equipment, in many cases, the vibration and shock conditions of the equipment are not stable and fixed, and various Different and complex and changeable vibration conditions, which will put forward strict and demanding requirements for vibration reduction

In order to meet complex and changeable vibration damping conditions, generally a plurality of coil springs with different spring characteristics are configured to meet the vibration damping requirements through a combined configuration, which will cause the vibration damping device to be extremely complex and bulky, and The vibration damping performance is still not able to meet the needs of the equipment well
