Embodiment 1

[0018] A conical spring, the spring is a single material, the cross-sectional area of ​​the spring gradually decreases from the spring top 1 to the spring bottom 2; the elastic coefficient of the spring is 21N / m from the elastic coefficient of the spring top 1, and the spring bottom The elastic coefficient of 2 is 1N / m, and the length of the spring is 20cm. The elastic coefficient of the spring changes linearly from the spring top 1 to the spring bottom 2, that is, kL=1+L*k2; L is the length of the spring from the spring bottom 2 , k2 is the elastic coefficient of spring bottom 2.

[0019] When a force of 1N is used to apply pressure to the spring, the elasticity of the spring is F=k*x, F is the spring force of the spring, and x is the deformation of the spring. It can be seen that the spring force of the spring increases gradually with the deformation of the spring. This increase is caused not only by an increase in spring deformation but also by an increase in the spring con...

Embodiment 2

[0021] A conical spring, the spring is a single material, the cross-sectional area of ​​the spring gradually increases from the spring top 1 to the spring bottom 2; the elastic coefficient of the spring is 1N / m from the spring top 1 to the spring bottom 2 The elastic coefficient of the spring is 21N / m, and the length of the spring is 20cm. The elastic coefficient of the spring changes linearly from the spring top 1 to the spring bottom 2, that is, kL=1+L*k1; L is the length of the spring from the spring top 1, k1 is the spring constant of spring top 1.

Embodiment 3

[0023] A kind of conical spring, this spring is a single material, the cross-sectional area of ​​this spring first increases and then decreases from spring top 1 to spring bottom 2; the elastic coefficient of this spring is 1N / m from the elastic coefficient of spring top 1, The elastic coefficient of the spring bottom 2 is 1N / m, the elastic coefficient of the spring middle 3 is 21N / m, the length of the spring is 40cm, and the elastic coefficient of the spring changes linearly from the spring top 1, the spring middle 3 to the spring bottom 2, namely kL =1+L*k1, or kL=1+L*k2, L is the length of the spring from the spring top 1 or the spring bottom 2, k1 is the elastic coefficient of the spring top 1, and k2 is the elastic coefficient of the spring bottom 2.

Abstract

The invention relates to a conical spring, which belongs to the technical field of springs. Elasticity coefficient of the spring is decreased or increased progressively from one end of the spring to the other end of the spring. When the spring is made of a single material, cross sectional area of the spring is increased or decreased progressively. When the spring is made of composite materials, the elasticity coefficient of the spring is increased or decreased progressively although materials of different stages of the spring are different. The conical spring can be widely applied to vehicle bumpers, spring beds, spring clamps, buffering seat cushions, machines, meters and sports equipment. The elasticity of the spring is gentle, so that the conical spring meets ergonomics, and direct injury to human bodies and objects can be avoided.

Description

technical field [0001] The invention relates to a conical spring and belongs to the technical field of springs. Background technique [0002] At present, the cross-sectional area and elastic coefficient of the springs in the world are constant from the beginning to the end, so the radial load of each spring and the radial stiffness of the spring are invariable. The flexibility of this kind of spring is very low. And the security is not good. Contents of the invention [0003] The purpose of the invention is to propose a conical spring in order to allow the spring to exert its greater value. [0004] The purpose of the present invention is achieved through the following technical solutions. [0005] In the conical spring of the present invention, the elastic coefficient of the spring decreases, increases, first increases and then decreases, or first decreases and then increases from one end of the spring to the other end of the spring. [0006] When the spring is a singl...
