Abstract
A spiral compression spring, the thread pitch and the diameter of which are variable, aims at solving the technical problem of unfavorable effect in a nonlinear application occasion of an equal stiffness spiral compression spring in the prior art. The invention is formed by coiling a piece of steel wire which is coiled into a spiral structure. The spiral structure at least comprises more than 3 effective screws. The distance between any two neighboring effective screws is larger or less than the distance between any two of the other neighboring effective screws. The diameters of the effective screws are all equal or the diameters of the effective screws change along a coaxial direction of the spiral structure. As the thread pitch of the spiral structure forming the spring changes, the spring can achieve a characteristic curve of variable stiffness. The invention forms the spring by utilizing the spiral structure steel wire with unequal thread pitches, thereby having a simple structure.
Description
Technical field:
The present invention relates to mechanical field, relate in particular to the elastic mechanical element, particularly a kind of variable-pitch variable-diameter spiral compression spring.
Background technique:
In the prior art, manufacturings such as machinery, electrical equipment, hydraulic pressure such as generally adopt as elastic element at the stiffness helix pressure spring.Characteristic curve Deng the stiffness helix pressure spring is a straight line, and therefore effect is undesirable in some nonlinear applications.
Summary of the invention:
The purpose of this invention is to provide a kind of variable-pitch variable-diameter spiral compression spring, described this variable-pitch variable-diameter spiral compression spring will solve prior art moderate stiffness spiral compression spring unfavorable technical problem of effect in nonlinear application.
This variable-pitch variable-diameter spiral compression spring of the present invention by a steel wire coil around constituting, wherein, described steel wire coil coiling structure, described helix structure includes the effective helix angle more than 3 at least, distance between any two adjacent effective helix angles all is greater than or less than the distance between remaining any two adjacent effective helix angle, and described gauge of wire is along the axial change of steel wire.
Further, the diameter of described effective helix angle all equates.
Further, the diameter of described effective helix angle is along all axial changes of described helix structure.
Further, described steel wire is coniform.
Perhaps, to connecting and composing, any one section described cylindrical diameter all is greater than or less than the cylindrical body of any one adjacent connection to described steel wire by at least two sections cylinder axis.
Working principle of the present invention is: change owing to constitute the pitch of the helix structure of spring, simultaneously, constitute the axial change of the gauge of wire of spring along steel wire, so spring can obtain to become the characteristic curve of rigidity.
The present invention and prior art contrast, and its effect is actively with tangible.The steel wire that the present invention utilizes diameter not wait constitutes the helix structure that pitch does not wait, and can obtain to become the characteristic curve of rigidity.Simple in structure.
Description of drawings:
Fig. 1 is the structural representation of variable-pitch variable-diameter spiral compression spring of the present invention.
Embodiment:
As shown in Figure 1, variable-pitch variable-diameter spiral compression spring of the present invention by a steel wire coil around constituting, wherein, described steel wire coil coiling structure 1, described helix structure 1 includes the effective helix angle 2 more than 3 at least, distance between any two adjacent effective helix angles 2 all is greater than or less than the distance between remaining any two adjacent effective helix angle 2, and described gauge of wire is along the axial change of steel wire.
Further, the diameter of described effective helix angle 2 all equates.
Perhaps, the diameter of described effective helix angle 2 is along all axial changes of described helix structure 1.
Further, described steel wire is coniform.
Perhaps, to connecting and composing, any one section described cylindrical diameter all is greater than or less than the cylindrical body of any one adjacent connection to described steel wire by at least two sections cylinder axis.
Working principle of the present invention is: change owing to constitute the pitch of the helix structure 1 of spring, simultaneously, constitute the axial change of the gauge of wire of spring along steel wire, so spring can obtain to become the characteristic curve of rigidity.
